Description

  The present invention relates to a technique for creating and displaying an enlarged image including a portion that is desired to be confirmed whether or not the image is good for a user from an image captured by a digital camera or the like.

  2. Description of the Related Art Conventionally, there has been known an image selection support device that supports effective selection of an image with a good image of a human image from a large number of images captured by a digital camera or the like (see, for example, Patent Document 1). ).

Among such image selection support devices, an image in which a feature part such as a face is partially enlarged is created for each image from the large number of images, and the created image group is displayed side by side (patent In paragraphs “0042” to “0050” of FIG. 1 and FIG. 9A), images obtained by partially enlarging feature portions such as thumbnails and faces are created from the large number of images, respectively, and the created thumbnails and enlarged images Are displayed in association with each other (see paragraph “0051” of FIG. 9B and FIG. 9B). As a result, it is possible to effectively select an image with a good image quality that is free from camera shake, out-of-focus, exposure setting error, frame-out, and the like from such a large number of images.

  However, in the image selection support apparatus as described above, there is a problem in that a portion for which it is desired to confirm whether or not the image looks good for the user is not always included in the above-described enlarged image. This is due to the following reason. That is, in the above-described image selection support device, an image in which a characteristic part such as a face is partially enlarged is created, but the part of the person who wants to check whether the image looks good for the user is the above-mentioned human face or the like Not necessarily. For example, there are cases where the user wants to check the clothes of a person who is the subject and the appearance of scenery such as plants and mountains. When a landscape is photographed instead of a person, the face of the person does not exist in the image.

  The present invention has been made in view of such a problem, and the object of the present invention is to include a portion where it is desired to confirm whether or not the image looks good for the user from an image captured by a digital camera or the like. The object is to provide a technique for creating and presenting an enlarged image.

  The image presentation system according to claim 1, which has been made to solve the above-described problem, is “a rectangular area that identifies the position of the focal point of an image when the image to be imaged is imaged, and that is centered on the focal position of the image. The feature is to create and present thumbnails from

  Specifically, the image presentation system of the present invention includes an “imaging device” that captures an image to be captured, and an “image presentation device” that creates and presents a thumbnail from the image captured by the imaging device.

  Among these, the imaging apparatus includes an “imaging unit” that can capture an image to be captured, an “instruction unit” that instructs the imaging unit to perform an imaging operation, a focus information specifying unit, a storage unit, and storage control. Means. The focus information specifying unit specifies a focus position in an image captured by the imaging unit. In addition, the storage control unit associates the “image” captured by the imaging unit and the “focus information” indicating the position of the focus specified by the focus information specifying unit, and stores them in the storage unit.

  On the other hand, the image presentation device includes an acquisition unit, a reception unit, a thumbnail creation unit, a presentation unit, and a presentation control unit. The acquisition means can acquire the image and focus information stored in the storage means of the imaging apparatus from the imaging apparatus, and the reception means is an “ordinary thumbnail presentation instruction” that is an instruction to present a normal thumbnail created from the image. Alternatively, it is possible to accept an “enlarged thumbnail presentation instruction” which is an instruction to present a thumbnail created from a rectangular area centered on the focal position in the image. When the accepting unit accepts the normal thumbnail presentation instruction, the thumbnail creating unit executes a normal thumbnail creating process for creating a normal thumbnail from the image acquired by the acquiring unit. On the other hand, when the accepting unit accepts the enlarged thumbnail presentation instruction, the thumbnail creating unit sets a rectangular area centered on the position of the focus acquired by the acquiring unit for the image acquired by the acquiring unit, and the image An enlarged thumbnail creation process for creating a thumbnail from the rectangular area is executed. Further, the presentation control means causes the presentation means to present the thumbnail created by the thumbnail creation means.

Specifically, as in claim 2, the accepting unit can accept a “both thumbnail simultaneous presentation instruction” indicating that a normal thumbnail and an enlarged thumbnail are presented side by side, and the thumbnail creating unit accepts both thumbnails. When the simultaneous presentation instruction is accepted, the normal thumbnail process and the enlarged thumbnail process are executed to create the normal thumbnail and the enlarged thumbnail, and the presentation control unit presents the normal thumbnail and the enlarged thumbnail created by the thumbnail creating unit. It is possible to present them side by side.

  According to the image presentation system of the present invention configured as described above, the normal thumbnail and the enlarged thumbnail presented by the user can be compared, so it is easy to confirm whether or not the image looks good. The user can check the focus, camera shake, etc. more easily.

The “presentation instruction” can be accepted. When the accepting unit accepts the normal thumbnail presentation instruction, the thumbnail creating unit executes a normal thumbnail creating process for creating a normal thumbnail from the image acquired by the acquiring unit. On the other hand, when the accepting unit accepts the enlarged thumbnail presentation instruction, the thumbnail creating unit sets a rectangular area centered on the position of the focus acquired by the acquiring unit for the image acquired by the acquiring unit, and the image An enlarged thumbnail creation process for creating an enlarged thumbnail from the rectangular area is executed. Further, the presentation control means causes the presentation means to present the thumbnail created by the thumbnail creation means.

  According to the image presentation device of the present invention configured as described above, an image captured by the imaging device and information indicating the focus position of the image are acquired, and the focus position in the acquired image is centered. Since a thumbnail is created from a rectangular area and presented, an enlarged image (thumbnail) that includes a portion that the user wants to check whether the image looks good is created and presented from an image captured by a digital camera or the like. Therefore, the user can easily confirm focus, camera shake, and the like.

  In this case, it is conceivable to present the above-described normal thumbnail and enlarged thumbnail side by side. Specifically, as in claim 4, when the accepting unit can accept the “both thumbnails simultaneous presentation instruction” and the thumbnail creating unit accepts the both thumbnails simultaneous presentation instruction, It is conceivable that the thumbnail processing and the enlarged thumbnail processing are executed to create a normal thumbnail and an enlarged thumbnail, and the presentation control unit causes the presentation unit to present the normal thumbnail and the enlarged thumbnail created by the thumbnail creation unit side by side.

  According to the image presentation device of the present invention configured as described above, since the normal thumbnail and the enlarged thumbnail presented by the user can be compared, it is easy to confirm whether or not the image looks good. The user can easily check focus, camera shake, and the like.

  As a specific example of the method of presenting the above-mentioned thumbnail to the user, as described above, the created thumbnail is displayed on a display unit such as a monitor, or the created thumbnail is printed on a recording medium such as paper. It is possible.

By thinning out in such a manner, an image having a smaller number of pixels than the number of pixels of the display unit 141 is generated. The image generated in this way is a reduced image that is smaller than the screen of the display unit 141. Then, the generated image is displayed on the display unit 141.

  (C) When an image is enlarged and displayed (enlarged display), the CPU 139 displays the entire image at a ratio of thinning out pixels from the original image stored in the frame memory area of the buffer memory 129. By setting the ratio smaller than the case, an image having a larger number of pixels than the number of pixels of the display unit 141 is generated. As a result, the image appears to be enlarged as compared with the case where the entire image is displayed on the display unit 141. Then, the generated image is displayed on the display unit 141. Note that, in the case of the maximum enlargement display, the pixel thinning process is not performed as described above.

This imaging process is executed when the imaging apparatus 100 is powered on.
First, the CPU 139 determines whether or not the release switch has been pressed by the user by determining whether or not the signal from the operation unit 137 has been received (S310). When the release switch is pressed by the user, the following steps are executed by controlling the memory controller 125. That is, the in-focus position (X1, Y1) is determined (S320, see FIG. 5A), and automatic exposure is determined (S330). Then, shooting information including information on the in-focus position is recorded in the buffer memory 129 in the data area of the buffer memory 129 (S340).

  Subsequently, it is determined whether or not to display the enlarged thumbnail on the display unit 216 (S430). Specifically, whether or not the user I / F 212 has received an “enlarged thumbnail presentation instruction” via the operation key 212 a is determined based on a signal transferred from the user I / F 212. When the user I / F 212 receives an “enlarged thumbnail presentation instruction” (S430: YES), the enlarged thumbnail is displayed on the display unit 216. That is, information on the in-focus position is read from the shooting information recorded in the RAM 208 (S440), and a partially enlarged image (enlarged thumbnail) is created around the in-focus position (X1, Y1) based on the information about the in-focus position. (S450). Then, the created enlarged thumbnail is displayed on the display unit 216 (S460, see FIG. 1), and this process is terminated.

  On the other hand, when the user I / F 212 has not received the “enlarged thumbnail presentation instruction” (S430: NO), a normal thumbnail instead of the enlarged thumbnail is displayed on the display unit 216. That is, the image data recorded by the RAM 208 is read, and a normal thumbnail image is created from the read image data (S470). Then, the created normal thumbnail is displayed on the display unit 216 (S480), and this process is terminated.

  When the user I / F 212 has not received the “enlarged thumbnail presentation instruction” as described above, it is further determined whether or not the user I / F 212 has received the “normal thumbnail presentation instruction”, and the user I / F 212 When F212 receives a “normal thumbnail presentation instruction”, a normal thumbnail image may be created and displayed on the display unit 216, and this process may be terminated.

First, image data is fetched from the IC card inserted into the IC card I / F 214 together with the associated shooting information (S515), and the fetched image data and shooting information are stored in the RAM 208 (S510).

  Subsequently, the image data recorded by the RAM 208 is read, a normal thumbnail image is created from the read image data (S515), and the created thumbnail is stored in the RAM 208.

  Subsequently, it is determined whether or not to display the enlarged thumbnail on the display unit 216 (S525). Specifically, whether or not the user I / F 212 has received an “enlarged thumbnail presentation instruction” via the operation key 212 a is determined based on a signal transferred from the user I / F 212. When the user I / F 212 has not received the “enlarged thumbnail presentation instruction” (S525: NO), a normal thumbnail instead of the enlarged thumbnail is displayed on the display unit 216. That is, the previously created normal thumbnail is read from the RAM 208 and displayed on the display unit 216 (S480), and this process ends. When the user I / F 212 has not received the “enlarged thumbnail presentation instruction” as described above, it is further determined whether or not the user I / F 212 has received the “normal thumbnail presentation instruction”, and the user I / F 212 When F212 receives a “normal thumbnail presentation instruction”, a normal thumbnail image may be created and displayed on the display unit 216, and this process may be terminated.

  On the other hand, when the user I / F 212 receives an “enlarged thumbnail presentation instruction” (S525: YES), the enlarged thumbnail is displayed on the display unit 216. That is, information on the in-focus position is read from the shooting information recorded in the RAM 208 (S530), and a partially enlarged image (enlarged thumbnail) is created around the in-focus position (X1, Y1) based on the information about the in-focus position. (S535).

  Subsequently, it is determined whether the normal thumbnail and the enlarged thumbnail are displayed side by side on the display unit 216 (S540). Specifically, it is determined by the signal transferred from the user I / F 212 whether or not the user I / F 212 has received a “both thumbnail simultaneous presentation instruction” via the operation key 212a. Note that “both thumbnail simultaneous presentation instruction” refers to an instruction to present a normal thumbnail and an enlarged thumbnail side by side. When the user I / F 212 receives the “Both Thumbnail Simultaneous Presentation Instruction” (S540: YES), the previously created normal thumbnail is read from the RAM 208, and the read normal thumbnail and the previously created enlarged thumbnail are displayed. The parts 216 are displayed side by side (S545, see FIG. 5B), and this process is terminated.

  On the other hand, if the user I / F 212 has not received the “Both Thumbnail Simultaneous Presentation Instruction” (S540: NO), the previously created enlarged thumbnail is displayed on the display unit 216 (S550), and this process ends.

As described above, according to the second embodiment, the normal thumbnail and the enlarged thumbnail are displayed side by side on the display unit 216. This makes it possible to compare the normal thumbnail and the enlarged thumbnail presented by the user, making it easier to check whether the image looks good and making it easier for the user to check focus, camera shake, etc. Can be done.
