Then, describe the action of the camera 1 of present embodiment 1 in detail with reference to Fig. 2 and Fig. 3.Wherein, action (action during the camera shooting pattern) when in the following description, being conceived to roughly show in real time image (hereinafter referred to as the browse graph picture) from imaging apparatus 102 on the TFT liquid crystal panel 144 as the part performance function of electronic viewfinder describes.Other actions can be and the general roughly the same actions of camera such as digital still image camera usually.For example, the active after camera 1 starting is done with general usually cameras such as digital still image camera roughly the same.Therefore, below, be purpose with the simplified illustration, omit its detailed icon and explanation.
When power knob in user's operation keys matrix 150 or lens cap etc., the action (camera shooting schema management step) of camera 1 when initiatively making the camera shooting pattern shown in Figure 2 of starting in the flow process.In addition, the camera shooting pattern is to go up the pattern that shows the subject image at electronic viewfinder (particularly the TFT liquid crystal panel 144).For example the opening/closing to this camera shooting pattern manages in CPU 110.In other words, the CPU 110 camera shooting schema management portion performance function that manages of the opening/closing of camera shooting pattern in contrast.
In the action when the camera shooting pattern, as shown in Figure 2, at first, camera 1 is carried out initialization process (step S101) under the control of CPU 110.Particularly, for example CPU 110 makes camera lens 101 move to initial position, and refreshes imaging apparatus 102 by actuator driving circuit 103 drive actuator 104.
Then, camera 1 is carried out live view photography (step S102).Particularly, under the control of CPU 110, drive imaging circuit 105, read and the corresponding signal of telecommunication of electric charge accumulation amount, generate analog picture signal, this picture signal is input to A/D change-over circuit 131 from imaging apparatus 102.131 pairs of analog picture signals of being imported of A/D change-over circuit are carried out the A/D conversion process, generate DID thus.View data after the A/D conversion is directly inputted to FIFO memory 132 by the total line traffic control based on internal bus 130, perhaps is input to FIFO memory 132 after the Digital Signal Processing by CPU 120 enforcement regulations.On the other hand, drive TFT liquid crystal display drive circuit 141 under the control of CPU 110 is read view data at every row from FIFO memory 132, be entered into TFT liquid crystal panel 144.At this moment, CPU 110 lights back light unit 143.Thus, on TFT liquid crystal panel 144, roughly show image in real time, as the browse graph picture based on the view data of reading from imaging apparatus 102 as the part of electronic viewfinder.
Then, camera 1 is according to the view data that generates in the live view photography of step S102, and whether the camera photosensitive degree of judging imaging apparatus 102 is less than predefined common minimum photosensitivity (step S103).Particularly, under the control of internal bus 130, will be input to CPU 120 from the DID of A/D change-over circuit 131 outputs.CPU 120 starting camera photosensitive degree decision-making functions 126 carry out this action, thus, calculate the light quantity of the optical image that incides imaging apparatus 102 according to the view data of being imported, judge that whether the camera photosensitive degree of obtaining according to this calculated value is less than predefined common minimum photosensitivity.
(step S103: not), camera 1 is transferred to common live view pattern, carries out this action (step S104) under the result of determination of step S103 for the camera photosensitive degree is situation more than the common minimum photosensitivity.In common live view pattern, the picture signal that obtains from imaging apparatus 102 is input to TFT liquid crystal display drive circuit 141 via A/D change-over circuit 131 and FIFO memory 132.Therefore, show directly that on TFT liquid crystal panel 144 this image is as the browse graph picture.
On the other hand, be (step S103: be) under the situation of camera photosensitive degree less than common minimum photosensitivity in the result of determination of step S103, camera 1 is transferred to pseudo-color live view pattern, carries out this action (step S105).In addition, below, the details of pseudo-color live view pattern is described with reference to Fig. 3.
After the action when the pseudo-color live view pattern of the common live view pattern of execution in step S104 or step S105, camera 1 returns initiatively and does.
Action when then, using Fig. 3 to describe pseudo-color live view pattern shown in the step S105 of Fig. 2 in detail.In the action when pseudo-color live view pattern, as shown in Figure 3, at first, camera 1 is set to zoom ratio wide-angle side (step S111) under the control of CPU 110.That is, when image pickup part generated view data (the 1st view data), the optical system that comprises camera lens 101 was set to wide-angle side with zoom ratio.Particularly, for example CPU 110 makes camera lens 101 move to wide-angle side by actuator driving circuit 103 drive actuator 104.Thus, on the sensitive surface of imaging apparatus 102, form under the technical conditions of camera 1 optical image of wide-angle.
Then, camera 1 drives photoflash lamp 106 (step S112) under the control of CPU 110, particularly photoflash lamp controlled function 112.Thus, the camera coverage to camera 1 throws light at least, and, on the sensitive surface of imaging apparatus 102, be formed for the optical image of the abundant light quantity of reproducing color therewith information.
Then, camera 1 drives imaging circuit 105 under the control of CPU 110, reads picture signal (step S113: the 1st shooting step) from imaging apparatus 102 thus.At this moment, the control by step S112 drives photoflash lamp 106, so, on imaging apparatus 102, form the optical image of abundant light quantity.Therefore, the picture signal of the image I M0 that reads from imaging apparatus 102 has the color of reproducing subject OB0 and background BK0 and is required to be sufficient signal strength signal intensity (colouring information) as shown in Figure 4.In addition, Fig. 4 is the figure that the example of the image I M0 that obtains when driving photoflash lamp 106 is shown.And the picture signal of being read is input to after A/D change-over circuit 131 carries out the A/D conversion process, outputs to internal bus 130 as DID (the 1st view data).Internal bus 130 total line traffic control according to the rules is input to CPU 120 with DID.
Like this, in the present embodiment, at CPU 110 (camera shooting schema management portion) when opening the camera shooting pattern, Lighting Division and image pickup part carry out at least once following processing: described subject is thrown light on, and generate view data (the 1st view data) according to the optical image of the subject of being thrown light on.
Then, camera 1 is at the view data that is input to CPU 120, extract the colouring information (the 1st colouring information) of each subject (or its zone) that this view data comprises, for example it is stored in (step S114: the colouring information analytical procedure) in not shown high-speed cache etc.Particularly, at first, CPU 120 accesses image identification function 121, makes this image identification function 121 extract characteristic point in the image according to the component of the color that view data comprised and gray scale etc., extracts zone in the recognition image as a result etc. according to this.Then, CPU 120 accesses subject recognition function 124, makes this subject recognition function 124 according to by the configuration in the zone of image identification function 121 identifications etc., (the subject identification steps) such as shapes of the subject that is comprised in the recognition image.Then, CPU 120 accesses colouring information analysis/representational role 123, makes this colouring information analysis/representational role 123 determine each regional colouring information by the subject of subject recognition function 124 identifications.Each regional colouring information of the subject that obtains thus is stored in not shown high-speed cache etc. as mentioned above.In addition, the colouring information of being stored also comprises the shape information of subject, the information of for example color region.
Then, camera 1 by actuator driving circuit 103 drive actuator 104, makes camera lens 101 return initial position (step S115) under the control of CPU 110 thus.
Then, camera 1 drives imaging circuit 105 under the control of CPU 110, reads picture signal as browse graph picture (the 2nd view data) (step S116: the 2nd shooting step) from imaging apparatus 102 thus.At this moment, do not drive photoflash lamp 106, so the light quantity of the optical image that forms is little on the sensitive surface of imaging apparatus 102.Therefore, the browse graph before the colour correction of reading from imaging apparatus 102 shown in Fig. 5 (a), becomes the required inadequate signal strength signal intensity of color (colouring information) of reproducing subject OB1 and background BK1 as the signal strength signal intensity (colouring information) of the picture signal of IM1.In addition, Fig. 5 illustrates the figure of browse graph before the colour correction of the present embodiment browse graph after as IM1 and colour correction as IM2 (with reference to Fig. 5 (b)).And subject OB0, OB2 among subject OB1 among Fig. 5 (a) and the entity of background BK1 and Fig. 4 and Fig. 5 (b) and the entity of background BK0, BK2 are identical.And then the picture signal of reading in step S116 is input to after A/D change-over circuit 131 carries out the A/D conversion process, is input to internal bus 130 as DID.Internal bus 130 total line traffic control according to the rules is input to CPU 120 with DID.
Then, camera 1 is carried out the graphical analysis (step S117) of the view data that is input to CPU 120.In addition, for convenience of explanation, will in this step S117, the view data as analytic target be called browsing image data, will be called the browse graph picture based on the image of this view data.In step S 117, particularly, at first, CPU 120 accesses image identification function 121, make this image identification function 121 extract characteristic point in the image, extract zone in the recognition image as a result etc. according to this according to the component of the color that browsing image data comprised and gray scale etc.Then, CPU 120 accesses subject recognition function 124, makes this subject recognition function 124 according to by the configuration in the zone of image identification function 121 identifications etc., the shape of the subject that is comprised in the identification browse graph picture etc.
Then, camera 1 reads out in the colouring information (the 1st colouring information) of each subject (or its zone) of storing among the step S114, and colouring information of being read and the subject of determining in the graphical analysis of step S117 (or its zone) are checked (step S118).Particularly, CPU 120 accesses colouring information analysis/representational role 123, and, read out in the colouring information of each subject (or its zone) of storing among the step S114, make colouring information analysis/representational role 123 determine the colouring information of each subject (or its zone) that subject recognition function 124 is discerned in this step S117.
The colouring information of each subject (or its zone) really usual practice as can followingly realizing: between the browsing image data of the view data of step S114 and this step S117, calculate each regional dynamic vector, between view data and browse graph picture, determine corresponding zone according to this dynamic vector, determine the colouring information of this corresponding region according to the colouring information of in step S114, storing.
Then, camera 1 is according to the colouring information (the 1st colouring information) of each subject (or its zone) of determining in step S118, and the colouring information (the 2nd colouring information) of each subject that view data comprised (or its zone) of looking like to read as browse graph in step S116 is proofreaied and correct (step S119: the colouring information aligning step).Thus, as the browse graph before the colour correction shown in Fig. 5 (a) as the browse graph of IM1 after the colour correction shown in Fig. 5 (b) as IM2, the browse graph of demonstration on as the TFT liquid crystal panel 144 of the part of electronic viewfinder is looked like to carry out colour correction (reproduction step).In addition, here, colouring information after the correction of each subject (or its zone) can carry out various distortion, and the color that for example is the information of each the regional average color in the view data, the subject (or its zone) that will determine in step S114 is directly as the information of texture etc.And the browsing image data after the colour correction is buffered in the FIFO memory 132 via internal bus 130 temporarily.Then, drive TFT liquid crystal display drive circuit 141 under the control of CPU 110 is read browsing image data at every row from FIFO memory 132, according to this browsing image data drive TFT liquid crystal panel 144.Thus, the browse graph after display color on the TFT liquid crystal panel 144 is proofreaied and correct is as IM2 (with reference to Fig. 5 (b)).
Then, to detect the posture (in other words for imaging apparatus 102 towards) of camera 1 self be camera pose information (step S120: the posture detection step) for camera 1.That is, the camera 1 of present embodiment have to image pickup part towards the posture detecting part that detects of variation.The test example of this camera pose information is as waiting the whole bag of tricks to realize by the following method: determine the camera pose of camera 1 according to the browsing image data that is taken in step S116, thereby judge the method whether this posture significantly changes; Tremble to proofread and correct and be used for posture detection being located at hand in the camera 1, detect the method etc. of the posture of camera 1 with gyrosensor 108 (with reference to Fig. 1).
Then, camera 1 judges whether camera pose information surpasses the predetermined limit (threshold value), be camera 1 photography direction towards or the composition of the optical image that on imaging apparatus 102, forms whether significantly change (step S121), under the situation that the variation of camera pose oversteps the extreme limit (step S121: be), return step S111, the view data during once more according to driving photoflash lamp 106 obtains the colouring information in each subject (or its zone).
Promptly, in present embodiment 1, posture detecting part detect image pickup part towards the situation of variation under, Lighting Division and image pickup part carry out at least once following processing: subject is thrown light on, and generate view data (the 1st view data) according to the optical image of the subject of being thrown light on, obtain its colouring information (the 1st colouring information).
But, the invention is not restricted to the situation that above-mentioned camera pose changes, for example also can constitute, detecting when having changed the situation etc. of the zoom ratio or the angle of visual field in manual or automatic mode, Lighting Division and image pickup part carry out at least once following processing: subject is thrown light on, and generate view data (the 1st view data) according to the optical image of the subject of being thrown light on, obtain its colouring information (the 1st colouring information).
On the other hand, if the result of determination of step S121 is variation (the step S121: not) of the camera pose that do not overstep the extreme limit, then camera 1 is judged the end indication (step S122) of whether having imported the action of the browse graph picture after display color on the TFT liquid crystal panel 144 is proofreaied and correct from for example key matrix 150, (step S122: not) under the situation of the end indication of not importing this browse graph picture demonstration, return step S116, obtain new browse graph picture, after it is carried out colour correction, the browse graph picture after display color on the TFT liquid crystal panel 144 is proofreaied and correct.Thus, the browse graph picture after display color is proofreaied and correct on as the TFT liquid crystal panel 144 of the part of electronic viewfinder is as the live view image.On the other hand, under the situation of having imported the end indication that the browse graph picture shows (step S122: be), the action when camera 1 returns the camera shooting pattern of Fig. 2.
As described above, in present embodiment 1, utilize to reproduce the colouring information (the 1st colouring information) of the view data (the 1st view data) of the subject sufficient signal strength signal intensity that color is required to be that comprises background, the colouring information (the 2nd colouring information) of browsing image data (the 2nd view data) that reproduction is comprised the subject inadequate signal strength signal intensity that color is required to be of background carries out colour correction.Its result in the present embodiment, also can show real subject image to the user via electronic viewfinder under the low-light (level) environment.
And, can on electronic viewfinder, show the identical image of image when driving photoflash lamp 106, so, can reduce the image when being taken into image and the image that is taken between the difference of tone.Its result in the dark also can be to user's realization uncomfortable operability seldom even can provide.
In addition, the subject identification part performance function discerned as the subject that view data (the 1st view data) and browsing image data (the 2nd view data) are comprised of the subject recognition function among the CPU 120 124.Therefore, the colouring information extraction unit is analyzed colouring information (the 1st colouring information) at by each subject in the view data (the 1st view data) of subject identification part identification.And, the colouring information correction unit utilizes the colouring information (the 1st colouring information) of view data (the 1st view data) that colouring information (the 2nd colouring information) is proofreaied and correct at by each subject in the browsing image data (the 2nd view data) of subject identification part identification.
(variation 1-1)
In addition, the renewal of the colouring information of subject is not limited to the situation (the step S 121 of Fig. 3: be) that the variation of camera pose oversteps the extreme limit.For example also can constitute, when the user aims at specific subject, upgrade the colouring information of this subject.Below, the variation 1-1 as present embodiment 1 describes with this situation.When in addition, aiming at subject for example is that first shutter 151 detects partly on time waiting of shutter release button.
