  Hereinafter, although an embodiment of an image evaluation apparatus of the present invention will be described, the present invention is not limited to this embodiment. The embodiment of the present invention shows the most preferable mode of the present invention, and the terminology of the present invention is not limited to this.

  FIG. 1 is a schematic configuration diagram of a photography system to which an image evaluation apparatus of the present invention is applied, and FIG. 2 is a diagram showing a monitor image display. The photographic system 1 of this embodiment is used when a subject 4 is photographed using a photographic photosensitive material in a studio such as a photo studio or an event venue.

  The photographic system 1 includes a main camera 2 that records an image on a photographic photosensitive material such as a photographic film or a photographic dry plate, and an auxiliary camera 3 that has at least part of the field of view of the main camera 2 as a field of view. The main camera 2 and the auxiliary camera 3 have substantially the same angle so that a large parallax does not occur between the main camera 2 and the auxiliary camera 3 with respect to the subject 4.

  The main camera 2 records an image on the photosensitive material 22 when the shutter 21 is opened. The auxiliary camera 3 includes an image sensor 31 such as a CCD, and converts an image of the subject 4 into an electrical signal. This electric signal is taken out in synchronism with the opening of the shutter 21 provided in the main camera 2. That is, an image is recorded on the photographic photosensitive material 22 when the shutter 21 of the main camera 2 is opened, and at the same time, the auxiliary camera 3 extracts an electrical signal for one screen relating to the same subject 4.

  The auxiliary camera 3 is configured to take out an electric signal for one screen, and is provided with a gate portion 32 through which an electric signal output from the image sensor 31 passes. The gate portion 32 receives an open signal output from the synchronization portion 33. It is released while The synchronization unit 33 generates an opening signal in a period in which an electrical signal for one screen passes in synchronization with the opening of the shutter 21 in the main camera 2.

  As the gate unit 32 and the synchronization unit 33, a commercially available electronic still camera or a built-in video camera capable of single-frame shooting can be used, and 1 is synchronized with the opening of the shutter 21 of the main camera 2. If the electrical signal for the screen can be extracted, it can be used for the auxiliary camera 2.

  A normal camera that can be used as the main camera 2 includes a flash tuning contact 23 and a motor drive tuning contact as a contact that is synchronized with the opening of the shutter 21, and an electronic still camera that is used as the auxiliary camera 3 has a release terminal. Therefore, if the contact point provided on the main camera 2 and the terminal provided on the auxiliary camera 3 are connected using a cable, the configuration for taking out an electrical signal for one screen in synchronization with the opening of the shutter 21 is easy. Can be realized. Note that, in order to take a picture in synchronization with the photographing operation, the flash tuning contact 23 may be used as a trigger for recording, or a signal from an element (not shown) for detecting light from the flash 24 may be used as a trigger.

  The same number of images recorded by the auxiliary camera 3 are recorded on the flexible disk by the disk drive 50 as recording means, and the images recorded on the flexible disk are reproduced by the reproduction means provided in the control device 5 after the photographing is completed. Read by a certain disk drive 51. Alternatively, the image may be recorded on the hard disk by the disk drive 50 as the recording means, and the image recorded on the hard disk may be distributed to the control device 5 and read by the disk drive 51 as the reproducing means after the photographing is finished.

  An image photographed by the auxiliary camera 3 is recorded on the disk drive 50 and simultaneously displayed on the monitor device 7 as display means. The monitor device 7 is preferably capable of color display, and normally a CRT is used, but a liquid crystal display or a projection type monitor device 7 may be used. In the monitor device 7, an image photographed by the main camera 2 is displayed for a certain period of time after the shutter 21 is opened, and the time for displaying an image photographed by the auxiliary camera 3 is limited to a certain period of time. Each image can be displayed sequentially when one photo is taken after another. Therefore, when the screen of the monitor device 7 is viewed, the facial expression of the subject 4 photographed by the main camera 2 can be confirmed immediately.

  An operation device 6 and a monitor device 8 are connected to the control device 5, and an image is displayed on the monitor device 8 by operation of the operation device 6. The control device 5 includes an image processing unit 52, a screen dividing unit 53, a monitor driving unit 29, a control unit 11, and an EEPROM 26. When a plurality of photographs are taken with the main camera 2, they are read out by the disk drive 51 as a reproducing means after the photographing is finished. That is, the disk drive 51 reads a plurality of still images to be compared among the still images recorded on a flexible disk or a hard disk as recording means.

  The image read by the disk drive 51 is displayed on the monitor device 8 by the image processing unit 52, the screen dividing unit 53, and the monitor driving unit 29 controlled by the control unit 11. The monitor device 8 includes monitor units 8a1 and 8a2 serving as comparison monitor units and a monitor unit 8b serving as a selection monitor unit. The monitor units 8a1, 8a2 and 8b have a relatively large screen and can be displayed in color. Since CRT is desirable, CRT is usually used.

  In addition, the control unit 11 controls the screen dividing unit 53 and the monitor driving unit 29 to select only a desired image from the plurality of images displayed on the monitor units 8a1 and 8a2 and display the selected image on the monitor unit 8b. In addition to the single device, the control device 5 may be one in which a video board is mounted on a personal computer and control software is installed. The monitor devices 7 and 8 may be other display devices such as liquid crystal, PDP, and organic EL.

  For example, as shown in FIG. 2, if the subject 4 takes eight types of photographs, in this case, the screen division unit 53 sets the screens of the monitor units 8a1 and 8a2 serving as the comparison monitor means to the same size. It is divided into four areas and displayed.

  As described above, the monitor units 8a1 and 8a2 which are comparison monitor means display a plurality of still images read by the reproducing means. The monitor unit 8a1 displays four images 1 to 4 one by one in order, and the monitor unit 8a2 displays the other four images 5 to 8 one by one.

  Here, the control unit 11 appropriately selects the images 1 to 8 displayed in the respective areas of the monitor units 8a1 and 8a2 that are comparison monitor means, and displays them on the monitor units 8a1 and 8a2. The monitor drive unit 29 is controlled.

  In this embodiment, the monitor unit 8b serving as the selection monitor unit is disposed between the monitor units 8a1 and 8a2 serving as the comparison monitor unit, and the still image selected by the monitor unit 8b is stored in the monitor units 8a1 and 8a2 before selection. By displaying in the center area, the selected still image is close to any of the still images that were not selected, making it easy to compare them. Can be done.

  The control unit 11 includes a CPU 11a, a ROM 11b, and a RAM 11c. The CPU 11a reads a control program stored in advance in the ROM 11b, expands it in the RAM 11c, and performs overall control according to the expanded program. Further, the CPU 11a executes various processes including a photographing evaluation process described later according to the developed program.

  The ROM 11b is composed of a non-luminous memory such as a semiconductor. The ROM 11b stores in advance various programs such as a control program and a processing program, and data referred to by the various programs. The RAM 11c temporarily stores programs and various data read from the ROM 11b in various processes executed by the CPU 11a.

  The monitor driving unit 29 drives the monitor 23 to display the digital image data output from the image processing unit 52. The operation device 6 includes a power switch, a reproduction switch, a touch panel, and the like, and outputs an operation signal from the user to the CPU 11a.

  The EEPROM 26 is composed of a nonvolatile memory, and preliminarily stores adjustment data used for various operations. In this embodiment, the EEPR0M 26 stores a smile evaluation reference table 261 and a straightness evaluation reference table 262.

  3A is a diagram illustrating an example of storing data in the smile evaluation criterion table 261. As illustrated in FIG. 3A, the smile evaluation criterion table 261 includes an element region 261a, a coefficient region 261b, and the like. The element region 261a stores data representing this component (for example, eyebrows, eyes, mouth) as “elements.” The coefficient region 261b has a corresponding face. The data (for example, 2, 5, 4) representing the coefficients of the constituent elements are stored as “coefficients.” The evaluation point area 261c stores the reference image of the corresponding facial constituent element and its evaluation points. For eyebrows, the rising reference image is associated with a lower evaluation point depending on the angle, and as the angle decreases, the reference image becomes a higher evaluation point. As for the eyes, the reference image whose pupil is closed is associated with a lower evaluation point due to the degree of opening of the pupil, and the higher the evaluation point as the pupil opens. The reference image is stored in association with the evaluation point, and when the eyes are closed, the reference image is stored in association with the evaluation point so as to be a negative point. The reference image in which is lowered is associated with a low point, and the reference image is stored in association with the evaluation point so as to become a high evaluation point as the angles of both ends increase.

  FIG. 3B is a diagram illustrating an example of data storage inside the straightness evaluation criterion table 262. As shown in FIG. 3B, the correct evaluation reference table 262 includes an element area 262a, a coefficient area 262b, and an evaluation point area 262c. The element area 262a stores data representing face components (for example, face 1, face 2, eyebrows,...) As “elements”. The coefficient area 262b stores data (for example, 1, 2, 2,...) Representing the coefficients of the corresponding face components as “coefficients”. The evaluation point area 262c stores the reference image of the corresponding facial component and its evaluation point.

  For example, with regard to the orientation of the face, those that face directly in front are regarded as high evaluation points, and those that face face to the left and right, and those that are necked, are standardized so that the higher the degree, the lower the evaluation point. Images are stored in association with evaluation points. The eyebrows are stored in association with the evaluation points so that a flat reference image has a high evaluation point, and a reference image with an increasing or decreasing angle has a lower evaluation point as its degree increases. Yes. The reference image is stored in association with the evaluation point so that the reference image with the pupil open has a high evaluation point, the reference image with the pupil closed, and the reference image with the eye closed has a low evaluation point. Yes. In the mouth, a reference image is stored in association with an evaluation point so that an image whose angle at both ends increases or decreases becomes a lower evaluation point.

  Next, the operation will be described. First, the captured image evaluation process executed by the CPU 11a will be described with reference to the flowchart of FIG.

  The CPU 11a waits for the playback switch to be pressed (step S1). When the playback switch is pressed (step S1; YES), the CPU 11a determines whether or not the evaluation mode is set (step S2), and determines that the evaluation mode is not set. Then (step S2; No), normal display processing is executed (step S3). That is, the CPU 11a performs image processing on an image obtained by photographing a subject and displays the image on the monitor device 8.

  On the other hand, when the CPU 11a determines that the evaluation mode is set in step S2, the CPU 11a displays a plurality of captured images (step S4). At this time, the displayed image is subjected to continuous shooting and a plurality of still images are displayed.

  After the still image is displayed, an input operation of the controller device 6 is used to evaluate the weight of the person (when calculating a smile evaluation value and a neat evaluation value, which will be described later, the other person is weighted to obtain the overall evaluation value of the frame image. When the instruction of (calculate) is input (step S5; YES), the CPU 11a displays a weighting setting screen on the monitor device 8, and for the person specified by the operation device 6, the specified order and its position. Information is acquired and set to be weighted and evaluated in the specified order (step S6).

  Next, the CPU 11a waits for the start of evaluation to be instructed by the operation device 6, and when the start of evaluation is instructed (step S7; YES), each subject person (person) in each captured frame image ) Face image is acquired and its position information is acquired, and smile evaluation (evaluation of the degree of smile of facial expression) and neat evaluation (evaluation of the degree of facial expression neatness) are performed for each face image (step) S8). For smile evaluation, reference is made to the smile evaluation criteria table 261 stored in the EEPROM 26, and the evaluation points of the shape of each element of the eyebrows, pupils and mouth of the face image are calculated, and each evaluation point is weighted by a coefficient. Are combined into a smile evaluation value for the face image of the frame image. For eyebrows and eyes, the evaluation points may be calculated for both the left and right to be ½, or one may be evaluated. As the neatness evaluation, referring to the neatness evaluation standard table 262 stored in the EEPROM 26, the evaluation points of the face orientation and the shape of each element of the eyebrows, the pupil and the mouth are calculated, and each evaluation point is weighted by a coefficient. Those are added together to obtain a positive evaluation value in the face image. For eyebrows and eyes, the evaluation points may be calculated for both the left and right to be ½, or one may be evaluated.

  Next, for each of the frame images, the CPU 11a calculates the average smile evaluation value and the average evaluation value calculated for each face image in step S10, and calculates the total smile evaluation value and the total correction value of each frame image. Here, the CPU 11a calculates the total smile evaluation value and the total correct evaluation value of each frame image when a weighted evaluation of the person is set in step S8. The algorithm calculates the total smile evaluation value and the total correct evaluation value by weighting the smile evaluation value and the correct evaluation value of the face image at the position of the specified position information or a position in the vicinity thereof based on the specified order. To do.

  Next, the CPU 11a analyzes one of the frame images, for example, the frame image 101, and determines whether the captured image is a casual scene or a formal screen (step S10). Specifically, the CPU 11a determines whether the scene is a formal scene or a casual scene, depending on whether it is indoor shooting or outdoor shooting, whether the clothes are dressed up, whether the hairstyle is rough, or the like. If it is determined that the shooting is for a casual scene (step S10; 1), the CPU 11a sets the priority evaluation value as a smile evaluation value (step S11). On the other hand, if it is determined in step S10 that the shooting is for a formal scene (step S10; 2), the CPU 11a sets the priority evaluation value as the formal evaluation value (step S12).

  Next, the CPU 11a extracts, for each person's face image, the face image of the frame image having the highest priority evaluation value among the frame images (step S13), collects the extracted face images, and synthesizes one frame. The image is synthesized (step S14). If there is only one person, step S13, step S14, and step S15 can be omitted. Further, for example, high facial expressions may be collected from facial parts to create one facial expression.

  Next, the CPU 11a sets the order from the highest priority evaluation value to each frame image with the composite image created in step S14 as the highest rank (step S15). Then, the CPU 11a creates an evaluation value file 211 in which evaluation value information including the total smile evaluation value and the total correct evaluation value corresponding to each frame image is arranged according to the rank and stored as a text file (step S16). In addition, the frame images are arranged in accordance with the ranks, and are stored as an image file in association with the evaluation file 211 (step S17). Then, the CPU 11a displays the highest frame image on the monitor device 8 (step S18).

  FIG. 5 is a diagram showing a data storage example of the evaluation value file 211 created in step S16 of FIG. As shown in FIG. 5, the evaluation value file 211 includes a NO area 211a, a NAME area 211b, a SMTILE area 211c, a FORMAT area 211d, a PERSON area 211e, a PERSON NO area 211f, an AREA area 211g, and SMILEP. The area 211h and the FORMAT area 211i are configured.

  The NO castle 211a stores data (for example, 1, 2,...) Indicating the priority evaluation value set in step S11 or 12 as “NO”. The NAME area 211b stores data indicating the name of the frame image (for example, DSC00001.xxx, DSC00002.xxx...) As “NAME”. The SMILE area 211c stores data (for example, 35, 25...) Representing the total smile evaluation value of the frame image as “SMILE”. The FORMAT area 211d stores data (for example, 32, 38...) Representing the overall correct evaluation value of the frame image as “FORMAT”. The PERSON area 211e stores data (for example, 3, 3,...) Representing the number of subjects (persons) photographed in the frame image as “PERSON”.

  In the PERSON NO area 211f, a code (for example, 001, 002, 003,...) Uniquely assigned to identify the person (person) photographed in the frame image is set as “PERSON No”. Store. The AREA area 211g is data (for example, (50.150) − (200.300), (100, 200) −) indicating position information of the face image of the photographed person to whom the corresponding code is assigned in the frame image. (600,700), (256.389)-(769,864),...) Are stored as “AREA”. The SMILEP area 211h stores data (for example, 40, 30, 35,...) Indicating the smile evaluation value of the subject to whom the corresponding PERSON NO is assigned as “SMILEP”. The FORMAT area 211i stores data (for example, 32, 29, 35,...) Indicating the correct evaluation value of the subject to whom the corresponding PERSON NO is assigned as “FORMALP”.

  FIG. 6 is a diagram showing an example of the data structure of the image file stored in the recording media 21 in step S17 of FIG. As shown in FIG. 6, the image file stores a comment area in which comments for the image file are stored, a frame image data area in which each frame image data is stored, and an evaluation value file corresponding to the image. It consists of an evaluation value file area. Each frame image data has a header area and an image information area. In the header area, auxiliary information regarding each frame image data is stored. This is an example of the data structure of a file based on these still images, but the present invention can also be applied to a file in a moving image format to facilitate image evaluation from a plurality of frames.

  In a moving image format such as MPEG, in order to compress the amount of information, a difference between a still image and a still image is extracted, encoded, and stored, and between the still images is complemented using the code during reproduction. However, it is desirable to evaluate each frame image in the captured image evaluation process using an “I picture (Intra-coded Picture)” having the most information amount as a still image. The image file data structure is not limited to this. For example, information in the evaluation value file may be stored in the comment area.

  The evaluation value file 211 stores the priority evaluation value rank, the overall smile evaluation value, the overall correctness evaluation value, the number of subjects to be photographed in association with each frame image captured by the moving image, and the frame image was captured. The face position information, smile evaluation value, and neat evaluation value for each person are also stored. As shown in FIG. 6, the evaluation value file 211 is stored in the recording medium 28 in association with the frame image data. Therefore, for example, by mounting the recording medium 28 on an external output device, it is possible to print on the external output device in the order of priority evaluation values.

  FIG. 7 is a diagram showing an example of a surface image display screen displayed on the monitor device 8 in step S18 of FIG. On the monitor device 8, the monitor units 8a1 and 8a2 which are comparison monitor units display a plurality of still images read by the reproducing unit, and the monitor unit 8a1 sequentially displays four images 1 to 4 one by one. The other four images 5 to 8 are displayed one by one on the monitor unit 8a2. The monitor unit 8b serving as the selection monitor unit is disposed between the monitor units 8a1 and 8a2 serving as the comparison monitor unit, and the still image selected by the monitor unit 8b is displayed in a substantially central region of the monitor units 8a1 and 8a2 before selection. To do.

  In this embodiment, there are provided evaluation means for displaying a plurality of images in the inputted photographed image and evaluating the facial expressions of the plurality of images. This evaluation means is constituted by the control unit 11 and is provided in the monitor units 8a1 and 8a2. Display multiple images and evaluate facial expressions of multiple images.

  It is a figure which shows an example displayed when it is judged on the screens 8a11 and 8a12 of the monitor part 8a1 as a casual scene by step S10 of FIG. On the screen 8a11, together with the frame image, the total smile evaluation value and the total correctness evaluation value of the frame image are displayed with the total smile evaluation value facing up. Only the overall smile evaluation value, which is the priority evaluation value, may be displayed together with the frame image. When display of the evaluation value of each subject is instructed by an operation from the operation device 6, the smile evaluation value and neat evaluation value of each subject are displayed as shown on the screen 8a12. Only the smile evaluation value of each subject may be displayed.

  It is a figure which shows an example displayed when it is judged on the screens 8a13 and 8a14 that it is a formal scene by step S10 of FIG. On the screen 8a13, together with the frame image, the total smile evaluation value and the total correct evaluation value of the frame image are displayed with the total correct evaluation value facing upward. Only the overall smile evaluation value, which is the priority evaluation value, may be displayed together with the frame image. When display of the evaluation value of each subject is instructed by an operation from the operation device 6, the smile evaluation value and the neat evaluation value of each subject are displayed on the screen 8a14. Only the correct evaluation value of each subject may be displayed. The screens 8a21 and 8a22 are diagrams illustrating an example displayed when weighting is set for the bride and groom images in step S6 of FIG. 4 and display of evaluation values of each subject is instructed. On the screen 8a21, the neat evaluation values of subjects other than the groom and the bride are low (20 to 40 points), but the neat evaluation values of the groom and the bride are high (70 points and 80 points). Increases to 74 points. On the contrary, as shown in the screen 8a22, although the neat evaluation values of the subjects other than the groom and the bride are high (80 to 90 points), the neat evaluation values of the groom and the bride are low (40 points and 30 points). The overall neat evaluation value is as low as 50 points.

  In this embodiment, it is possible to display a plurality of images in the input captured image and evaluate the quality of the facial expressions of the plurality of images. Therefore, for example, the user can quickly select an order image for a photo print, the rotation rate of shooting in a studio such as a photo studio or an event venue is improved, and the user's satisfaction is also improved.

  FIG. 8 is a diagram showing an embodiment in which evaluations are extracted from a plurality of images and displayed side by side. In this embodiment, evaluations are extracted from a plurality of images and displayed side by side on the screens 8a11 to 8a14 of the monitor unit 8a1, and the image number, the part used for the determination, and the evaluation are displayed. The image numbers are, for example, number 025 to number 028. If there is no image number, it will be unknown. As a part used for the determination, for example, eyes are used, but a mouth or the like may be displayed. As an evaluation, for example, evaluation points are given, but the highest rank may be ranked with ◎, the lowest rank with ×, etc. The evaluation is a numerical value or a rank, and it is possible to easily and reliably evaluate the quality of the facial expression of the image without fail. In addition, the evaluation may support the user's selection not only by numbers but also by warnings such as pictograms by rank and blinking.

  As described above, since the evaluation is extracted from the plurality of images and displayed side by side, it is easy to compare them. Therefore, it is possible to quickly and easily evaluate the quality of the expressions of the plurality of images. Furthermore, by displaying at least one of the image number, the part used for the determination, and the evaluation, it is possible to easily and reliably evaluate the quality of the expressions of the images without fail.

  FIG. 9 is a diagram showing an embodiment provided with a touch panel of an operation screen provided in the operation device. On the touch panel 60 of this embodiment, an operation instruction display 61 is displayed. When each part 71 to 75 of the image 70 displayed according to the operation instruction display 61 is selected and touched with the cursor 76 or the like, the image number, The part and evaluation used for the judgment are displayed.

  For example, when the eyebrows 72, the eyes 73, the mouth 74, etc. are touched, only the eyebrows 72, the eyes 73, the mouth 74 are discriminated from each image, and they are scored in close-up. When the eye 73 is touched, the screen is displayed as shown in FIG. In this way, it is possible to select a part of the image by the touch panel 60 and evaluate the quality of the image.

  When the props 71 and 75 are touched with the cursor 76 or the like, the evaluation of the props 71 and 75 is displayed. The evaluation of the props 71 and 75 is whether or not they are covered with a person (skin color), whether or not the costume and hue are separated (if they are the same, they are buried). The props 71 and 75 can be easily separated from costumes, persons, and backgrounds by registering colors and shapes in advance.

  In this embodiment, the background is evaluated. For example, the evaluation is made based on whether the three sides 77a to 77c of the background are cut off, and there is no extra reflection such as a lamp 78, or whether the clothes, props, hues and brightness are not separated from each other. . The props and backgrounds need not be discriminated in detail, and may be ranked in three stages such as A, B, C, or ◯, Δ, or X, for example.

  FIG. 10 is a diagram showing an embodiment in which an image with high evaluation is first arranged on the selection screen. In this embodiment, a monitor unit 8b which is a selection monitor unit and monitor units 8a1 to 8a8 which are comparison monitor units are arranged around the monitor unit 8b, and a highly evaluated image is displayed on the selection screen of the monitor unit 8b. Place it first. This may be the highest level image synthesized in step S14. In this way, the selected still image with a high evaluation is displayed in a substantially central region of the plurality of still images before selection.

  For example, on the monitor units 8a1 to 8a8, the total score of the image and the evaluation is displayed, the total score of the image of the monitor unit 8a1 is 88 points, and an image with high evaluation is first displayed on the selection screen of the monitor unit 8b. .

  For example, the total point of the image can be determined by weighting the background 20%, the expression 50%, and the prop 30%. Further, the score display is not limited to the total score display of the image, and for example, the score display for each part used for the determination of the eyes, the mouth, etc., the score display of the weighted evaluation of the person, and the like can be performed.

  In this embodiment, by placing an image with high evaluation on the selection screen first, for example, the user can quickly select an order image of a photo print by paying attention to the selection screen, and a studio such as a photo studio or an event venue. In addition, the rotation rate of shooting is improved and user satisfaction is also improved.

  Further, by displaying at least one of the image number of the selection screen, the part used for the determination, and the evaluation, it is possible to easily and reliably evaluate the quality of the expression of the plurality of images without fail. If the number of pixels of the auxiliary camera is suitable for printing, the main camera can be omitted. Even if the auxiliary camera is a moving image camera, it is easy to select a frame suitable for printing from the frames. In this way, this system can continue to be used effectively in the future.

  This image evaluation device can quickly and easily select a photograph with good image quality. For example, when photographing a subject using a photographic photosensitive material in a studio such as a photo studio or an event venue. It can be applied to the photography system used.
