  The preprocessing unit 105 has a function of performing white balance processing for adjusting white balance of an image based on input image data and gamma correction processing for an image (image data). The white balance process is a process of adjusting the color of an image so as to be close to the actual color, or adjusting the color to an appropriate color that matches a light source (such as a fluorescent lamp or sunlight). The gamma correction process is a process for adjusting the contrast of an image. Note that the pre-processing unit 105 can also perform image processing other than white balance processing and gamma correction processing.

  The YC processor 106 separates an image based on input image data into luminance information “Y”, luminance signal and blue color difference information “Cb”, and luminance signal and red color difference information “Cr”. Have The electronic zoom processing unit 107 has a function of trimming a part of an image (for example, a central part) with a predetermined size and enlarging the trimmed image to the size of the original image by signal processing. The electronic zoom processing unit 107 can, for example, cut out a central 1024 × 768 dot image from a captured 1600 × 1200 dot image and enlarge it to a size of 1600 × 1200 dot while performing data interpolation.

  The compression unit 108 has a function of compressing image data in a compression format such as a JPEG (Joint Photographic Expert Group) method. The decompression unit 109 has a function of decompressing compressed image data. For example, when compressing image data using the JPEG method, first, a discrete cosine transform process is performed (DCT process) that digitizes the ratio of high-frequency components and low-frequency components of image data. Next, a quantization process is performed for expressing the gradation or gradation of the image by a numerical value (quantization bit number). Finally, the image data is compressed by the Huffman encoding process.

  Specifically, the signal character string of the image data is segmented every certain bit, and a shorter code is given to a character string having a high appearance frequency. In the case of a system that records image data without performing compression processing, the compression unit 108 and the expansion unit 109 can be omitted. Further, the image data compression format is not limited to the JPEG format, and the same processing can be performed even in a GIF (Graphical Interchange Format) format.

The operation unit 120 includes operation buttons other than the illustrated operation buttons, but a description thereof is omitted.

  A mode dial (select button) 122 is a rotatable dial for switching the mode of the photographing operation. The user can select a plurality of shooting operation modes by operating the mode dial 122. In the embodiment of the present invention, the mode dial is described as a dial type mechanism. However, for example, a slide type button may be used instead of the dial. That is, the mechanism of the mode dial 122 is not limited to the dial, and it is essential to have a mechanism for switching the camera mode.

  The browsing button 126 is a button for switching to a browsing mode (playback mode) for browsing captured image data. When the browse button 126 is pressed, the shooting mode is changed to the browsing mode. Note that the method for switching to the viewing mode is not limited to pressing the viewing button 126, and may be a transition method using a touch panel (not shown) on the liquid crystal display 117 or the like.

  In the browsing mode, the system controller 110 reads setting information and image data from the memory card 115 attached to the card holder 114 via the I / F circuit 113. The setting information includes the number of images recorded on the currently installed memory card 115 and the capacity of the recorded image data. The read image data is, for example, image data for one image or thumbnail image data. Note that the image data read from the memory card 115 is compressed in a predetermined compression format as described above.

  The image data read from the memory card 115 is input to the display driver 116 via the I / F circuit 113 and the system controller 110. The display driver 116 displays the input image data on the liquid crystal display 117.

  The cursor key 124 is a key for the user to perform a predetermined instruction or function selection to the photographing apparatus. The user can perform operation inputs such as various setting information and user authentication information with respect to the photographing apparatus using the cursor key 124.

Furthermore, the cursor key 124 can display a preview of the image data photographed by the photographing device on the liquid crystal display 117. The preview display is a function of causing the liquid crystal display 117 to display an image captured by the imaging apparatus 100 immediately after that.

  Note that the preview display is not limited to a configuration in which only one image captured on the liquid crystal display 117 is displayed, and a plurality of images including thumbnail images may be displayed. Further, the switching of the preview display is not limited to the pressing of the cursor key 124 but may be configured to be switched using a general method such as pressing of another button. Further, the preview display screen may be configured such that the preview display image can be deleted or edited.

  The lens control unit 127 controls the lens 101 such as zoom, focus, and diaphragm. In addition, the photographing apparatus includes a photographing mode for capturing an image of a subject to obtain image data and a browsing (reproducing) mode for displaying the image data obtained in the photographing mode.

  Note that the sound can be recorded and reproduced in the same manner as the imaging apparatus by using a microphone or a speaker. Further, when recording video (moving image), normal audio recording is also performed at the same time, and video and audio are multiplexed by the compression unit 108 and the expansion unit 109.

  In addition, a photographing operation in the imaging apparatus 100 will be described with reference to FIG. First, the user operates the power switch 121 to turn on the imaging apparatus 100. Then, power is supplied to each circuit from a battery (not shown) built in the imaging apparatus 100, and activation processing of the imaging apparatus 100 (operation control for opening the lens barrier, reset processing of the microcomputer, etc.) is performed. The imaging apparatus 100 is configured to turn on the power when the power switch 121 is pressed when the power is turned off, and to automatically enter the shooting mode. Further, when the viewing button is pressed when the power is turned off, the power is turned on and the viewing mode is automatically set.

  When the imaging apparatus 100 shifts to the imaging mode, an optical image enters the imaging apparatus via the lens 101 and forms an image on the imaging element (CCD) 102. The CCD 102 converts an incident optical image into an electric signal and outputs it to a camera signal processing unit (ADC) 103. The ADC 103 converts an input electric signal (analog signal) into a digital signal. A digital signal output from the ADC 103 is input to the image processing unit 104.

  A preprocessing unit 105 in the image processing unit 104 generates image data based on an input digital signal, and performs white balance processing, gamma correction processing, and the like. In the YC processing unit 106 in the image processing unit 104, the image data is separated into the luminance signal Y and the color difference signals Cr and Cb, and processing for reducing the information amount of the color difference signals Cr and Cb is performed. The information amount reduction processing for the color difference signals Cr and Cb is, for example, “4: 2: 2 downsampling processing” for thinning out color information in the main scanning direction of an image, or “4: 1” for thinning out color information in the vertical and horizontal directions of an image. : 1 downsampling process ". When image processing is performed by the pre-processing unit 105 and the YC processing unit 106, image data is temporarily stored in the buffer memory 111, and image processing is performed while reading the image data stored in the buffer memory 111 as needed. Is called.

  Image data (uncompressed) output from the image processing unit 104 is input to the system controller 110. The system controller 110 outputs the image data output from the image processing unit 104 to the display driver 116. The display driver 116 converts input image data (digital signal) into an analog image signal, and adjusts the size of the image based on the analog image signal to a size that can be displayed on the liquid crystal display 117.

  The display driver 116 controls the liquid crystal display 117 to display an image. At this time, the image displayed on the liquid crystal display 117 is an image (through image) generated by signal processing continuously performed by the CCD 102, the ADC 103, and the image processing unit 104.

  When the user operates the shooting button 123 at a desired timing while the through image is displayed on the liquid crystal display 117, the system controller 110 outputs a control signal to the image processing unit 104. When a control signal is input to the image processing unit 104, the compression unit 108 stores the image data processed by the preprocessing unit 105 and the YC processing unit 106 in the buffer memory 111 and performs compression processing.

  Specifically, discrete cosine transform processing (DCT processing) that digitizes the ratio of high-frequency components and low-frequency components of image data, and quantization that expresses the gradation and gradation of an image with the number of quantization bits Processing, Huffman coding processing for dividing a signal character string of image data into fixed bits and giving a shorter code to a character string having a high appearance frequency is performed. The compressed image data is displayed on the liquid crystal display 117 via the system controller 110 and the display driver 116. The compressed image data is recorded on the memory card 115 via the card holder 114.

  When the zoom button 125 is operated before the shooting button 123 is operated, the system controller 110 can execute an optical zoom process or an electronic zoom process to enlarge or reduce the size of the image. When the shooting button 123 is operated after the zoom button 125 is operated, the image data of the enlarged or reduced image is recorded in the memory card 115.

  The level 130 detects and measures the tilt of the imaging device 100. The azimuth sensor 131 measures the direction (azimuth) that the imaging apparatus 100 is facing. The above is the description of the hardware configuration and imaging function of the imaging apparatus 100 according to the embodiment of the present invention shown in FIG.

The scene discriminating unit 201 is a discriminating unit that discriminates a shooting scene when performing shooting processing (imaging processing). The shooting scene is, for example, a state of an image being shot that is determined at the time of shooting an image by a scene determination function (such as a function for automatically switching shooting modes) installed as a function of the imaging device. It refers to shooting scene data stored in the shooting apparatus, which is applied when shooting depending on the state of the image.
For example, there are a person (portrait) shooting scene, a landscape shooting scene, an object shooting scene, an animal shooting scene, a macro shooting scene, a high-speed shooting scene, and the like.

  In addition, the shooting scene may be determined using information on the image after shooting. For example, images taken during a predetermined time range within a predetermined distance range using the shooting position of the image, the shooting time, and the face information of the person included in the image, and the same number or more You may make it discriminate | determine the image containing a person as an image image | photographed in the same scene.

  The imaging execution unit 202 is an execution unit that executes imaging processing by switching the imaging mode, for example, according to the determined imaging scene. The image storage unit 203 is a functional unit that performs control for storing images. For example, control is performed to store the image in the memory of the imaging apparatus or to store the image in a memory card connected to the imaging apparatus.

  The print image selection reception unit 204 is a selection reception unit that receives selection of an image to be printed (print image / image to be printed) from images displayed on the display screen. The print group storage unit 205 is a control unit that collectively stores the images received by the print image selection reception unit 204 in groups.

  The scene-specific display switching unit 206 is a switching unit that switches an image display method according to scene information corresponding to an image displayed on the display screen. The above is the description of the functional configuration of the imaging apparatus 100 according to the embodiment of the present invention shown in FIG.

  Next, an overview of processing in the embodiment of the present invention will be described with reference to FIG. FIG. 3 is a flowchart showing an outline of processing in the embodiment of the present invention.

The imaging apparatus 100 performs a photographing process according to a user instruction (step S301), displays the photographed image on a display screen, and accepts a selection process for the image (step S302). Details of the photographing process (step S301) will be described later with reference to FIGS. Details of the image selection process (step S302) will be described later with reference to FIG. The above is the description of the outline of the processing in the embodiment of the present invention shown in FIG.
Next, with reference to FIG. 4, an outline of the photographing process in the embodiment of the present invention will be described. FIG. 4 is a flowchart showing an outline of the photographing process.

  The imaging apparatus 100 receives an instruction from the user (step S401), and determines whether the received instruction is a shooting instruction (step S402). That is, for example, it is determined whether or not a release pressing instruction has been received.

  If it is determined that the received instruction is not a shooting instruction (NO in step S402), the process proceeds to step S407. If it is determined that the received instruction is a shooting instruction (YES in step S402), it is determined whether the shooting mode is set to the scene determination shooting mode (step S403).

  The scene determination shooting mode here refers to a scene ID for dividing a shot image into scenes after shooting according to the shooting situation (shooting location, time, subject state, etc.). This is a shooting mode for dividing (grouping).

  The scene determination and grouping processing will be described later with reference to FIG. The embodiment of the scene determination shooting mode is not limited to that described above. For example, a shooting mode generally installed as a function of the shooting device, for example, for each scene (person (portrait) shooting scene, landscape shooting scene, object shooting scene, animal shooting scene, macro shooting scene, high-speed shooting scene, etc.) That is, an auto shooting mode in which shooting is performed by changing parameters (exposure, aperture, shutter speed, etc.) used for shooting may be the scene determination shooting mode in the embodiment.

  When it is determined that the shooting mode is not set to the scene determination shooting mode (NO in step S403), the imaging apparatus 100 captures an image and stores it in the memory card (step S406).

  If it is determined that the shooting mode is set to the scene determination shooting mode (YES in step S403), the process proceeds to step S404 to perform scene determination shooting (step S404). Details of the scene determination shooting will be described later with reference to FIG.

  Here, with reference to FIG. 5, the details of the scene determination shooting process in the embodiment of the present invention will be described. FIG. 5 is a flowchart showing details of the scene determination photographing process in the embodiment of the present invention.

  The imaging apparatus 100 acquires information on the current position of the imaging apparatus using a GPS function mounted on the imaging apparatus 100, and acquires information on the current time using a clock function mounted on the imaging apparatus 100.

  Next, the imaging apparatus 100 acquires subject information from the image data being captured. The subject information here is, for example, a feature amount of an image acquired from an image being captured. (For example, the feature amount of the face image is acquired).

  The imaging apparatus 100 executes a shooting process for storing the image as a still image or a moving image in a storage unit such as a memory card (step S503), and determines whether the shooting is the first shooting in the imaging apparatus ( Step S504).

  When it is determined that the shooting is the first shooting in the imaging apparatus (YES in step S504), the imaging apparatus 100 specifies information on the subject (that is, specifies what / who is the subject / step). (S510), a scene ID for identifying the scene of the image acquired by the shooting is issued (step S511), the scene ID and the image acquired by the shooting in step S503 are associated with each other in the memory card. Store (step S509). At this time, the position information and shooting date / time information acquired in step S501 are also stored in association with the image. Details of the method for identifying the subject and the scene ID will be described later with reference to FIG.

  Here, an example of the configuration of the image data table in the embodiment of the present invention will be described with reference to FIG. FIG. 14 is a diagram showing an example of the configuration of an image data table in the embodiment of the present invention.

  As shown in FIG. 14, the image data table 1400 includes a name 1401, an image 1402, a latitude / longitude 1403, a shooting date / time 1404, face information 1405, a shooting mode 1406, a scene ID 1407, and the like. The face information registration table 1410 includes a user name 1411, a feature amount 1412, and the like.

  A name 1401 is the name of the image. Here, it is assumed that the name 1401 is unique for each image. An image 1402 is actual image data. Latitude / longitude 1403 is position information at which an image is taken.

  The shooting date / time 1404 is the shooting date / time of the image. The face information 1405 is specified by using subject information (feature amount) and information on the feature amount of the user's face registered in the face information registration table 1410 in advance. It is information indicating whether it is included in.

  The feature amount of the user's face is the feature amount of the face photographed when the photographing instruction is received on the face information registration screen (not shown). For example, the face information registration displayed on the face information registration screen (not shown) Is received in the face information registration table 1410 by accepting the pressing of the button for. As for the user name 1411, the user name input on the face information registration screen (not shown) is stored and registered.

  The subject (user) specifying process is performed in steps S506 and S510 in FIG. 5, for example. Information on the identified subject (for example, face information 1405) is stored in a storage medium such as a memory card in association with the image in step S509 of FIG.

  In the face information 1405, if the subject (feature amount of the face image) specified in step S510 of FIG. 5 and step S506 described later is already registered in the face information registration table 1410, the specified subject (face It is assumed that a user name 1411 corresponding to the image feature amount is inserted.

  If a face image is recognized as a subject but the face information is not registered in the face information registration table 1410, a value indicating that the subject is unknown is inserted into the face information 1405. If the face image is not recognized, for example, a null value is inserted.

  The user name 1411 is the name of the user of the face indicated by the feature value 1412 that is registered in advance by the user and stored in a storage medium such as an external memory of the imaging apparatus 100. The feature amount 1412 is face information (a feature amount of a face image) registered in advance by the user.

  The shooting mode 1406 is scene information when, for example, the above-described auto shooting mode of the imaging apparatus 100 is activated, and a scene is determined and shooting is performed in the auto shooting mode.

  The scene ID 1407 is an ID (identification information) that is assigned to the image separately from the information of the shooting mode 1406 and is used for scene division (grouping for each scene). The scene ID 1407 is given to the image by the imaging apparatus 100 according to, for example, the situation at the time of shooting (shooting place, time, subject state, etc.).

  For example, after a certain image is captured, a scene ID is assigned to the image, and when another image is captured, the distance between the position where the first image and the second image are captured is The first image is within the predetermined threshold value, the shooting time is within the predetermined threshold value, and the same user (face image) is included in the two images more than the predetermined number (threshold value). It is assumed that the same ID as that assigned to is assigned to the second image.

  Each threshold value is assumed to be stored in advance in a storage medium such as an external memory of the imaging apparatus 100, and can be arbitrarily changed in accordance with a user operation instruction. For example, if the distance between the shooting positions of two images is within a predetermined threshold and the shooting time is within a predetermined threshold, it may be determined that the scenes are the same, or the shooting time is within a predetermined threshold. Thus, when the same user (face image) is included in the two images, it may be determined that the scene is the same.

  Further, if the face images included in the two images are the face images of the user registered in the face information registration table and the number of the face images matches a predetermined number or more, they are regarded as the same scene. Good.

  Note that the combination of the conditions of the shooting time, shooting position (location), and subject (face information) in determining whether the shot image is an image of the same scene as the previous shot image is limited to the above combination. is not. The above is an example of the configuration of the image data table in the embodiment of the present invention shown in FIG.

  Returning to the description of FIG. If the imaging device 100 determines in step S504 that the shooting performed in step S503 is not the first shooting (NO in step S504), has the shooting been performed in the same place as the previous shooting? Is determined (step S505). That is, if the shooting performed in step S503 is the second or later shooting, is the distance from the position where the shooting performed immediately before to the position where shooting was performed in step S503 within a threshold? Determine.

  If it is determined that the shooting is not the same location as the previous shooting location (NO in step S505), the process proceeds to step S510. If it is determined that the shooting is the same location (within a predetermined range) as the location where the previous shooting was performed (YES in step S505), the process proceeds to step S512.

  The imaging apparatus 100 determines whether or not the shooting has been performed within a predetermined time (time within a threshold range) from the time when the previous shooting was performed (step S512). If it is determined that the shooting has not been performed within a predetermined time from the time when the previous shooting was performed (NO in step S512), the process proceeds to step S510. If it is determined that the shooting has been performed within a predetermined time from the time when the previous shooting was performed (YES in step S512), the process proceeds to step S506.

  The imaging apparatus 100 determines whether the subject of the image (captured image) acquired by the imaging has been changed from the immediately preceding captured image (step S506). If it is determined that the subject of the captured image acquired by the capturing has not been changed from the immediately preceding captured image (NO in step S506), the process proceeds to step S508. If it is determined that the subject of the photographed image acquired by the photographing has been changed from the previous photographed image (YES in step S506), the process proceeds to step S507.

  The imaging apparatus 100 determines whether or not the subject (face) registered in the face information registration table 1410 has been changed from the immediately preceding captured image by a predetermined number or more, which is the subject of the captured image acquired by the capturing (see FIG. Step S507).

  If it is determined that the subject (face) registered in the face information registration table 1410 has been changed by a predetermined number or more from the immediately preceding captured image (YES in step S507), the process is performed. The process proceeds to S511.

  If it is determined that the subject (face) registered in the face information registration table 1410 has not been changed by a predetermined number or more from the immediately preceding captured image (NO in step S507), the process is performed. The process proceeds to S508, the scene ID given to the photographed image acquired by the previous photographing is specified, and the same ID as the scene ID given to the photographed image obtained by the previous photographing is performed in step S503. Is stored in association with the captured image acquired in step S508.

  That is, the previous captured image and the current captured image are stored in a storage medium such as a memory card as an image of the same scene. The above is the description of the details of the scene determination photographing process in the embodiment of the present invention shown in FIG.

  Returning to the description of FIG. The imaging apparatus 100 determines whether or not the instruction received in step S401 is an instruction to end shooting (step S407). If it is determined that the instruction is not an instruction to end shooting (NO in step S407), the process is performed before step S403. If it is determined that the instruction is to end shooting (YES in step S407), the process ends. The above is the description of the outline of the photographing process in the embodiment of the present invention of FIG.

  Next, details of image display and selection processing for each scene in the embodiment of the present invention will be described with reference to FIG. FIG. 6 is a flowchart showing details of image display and selection processing for each scene in the embodiment of the present invention. FIG. 6 shows details of the process in step S302 of FIG.

  The imaging apparatus 100 accepts an instruction to display a captured image. For example, an instruction to press the browse button 126 is accepted (step S601). The imaging apparatus 100 acquires a representative image for each scene and displays the list on the display screen (list display) (step S602). The representative image for each scene here is, for example, an image that is first photographed in an image group having the same scene ID 1407. The list display screen will be described later with reference to FIG.

  Here, an example of the configuration of the scene list display screen in the embodiment of the present invention will be described with reference to FIG. FIG. 7 is a diagram showing an example of the configuration of the scene list display screen in the embodiment of the present invention.

  As shown in FIG. 7, the scene list display screen 700 includes a scene representative image 701, a “return” button 702, a “print selection” button 703, and the like. The scene representative image 701 is a representative image in an image group having the same scene ID 1407.

  The “return” button 702 is a button for transitioning the display screen to a screen before the scene list display screen 700 is displayed. The “print selection” button 703 is a button for changing the display screen to a screen for selecting an image to be printed from images that have been taken (images stored in a memory card). Details of the screen for selecting an image to be printed will be described later with reference to FIGS. The above is an example of the configuration of the scene list display screen in the embodiment of the present invention shown in FIG.

  Note that when a selection instruction such as a tap operation on the scene representative image 701 in FIG. 7 is received, the imaging apparatus 100 displays the display screen as an image list display screen 800 (for browsing the image of the selected scene). It is assumed that the process proceeds to FIG.

  The image list display screen 800 in FIG. 8 displays a representative image 801 and a thumbnail image 802 that is a thumbnail of an image corresponding to the same scene ID as the representative image excluding the representative image.

  Returning to the description of FIG. The imaging apparatus 100 accepts a screen transition instruction to the print image selection screen (step S603). For example, an instruction to press the “print selection” button 702 in FIG. 7 is accepted.

The imaging apparatus 100 extracts one unregistered image as a print image from the images stored in the memory card, and specifies scene information of the image (step S604). That is, the information of the shooting mode 1406 of the extracted image and the information of the scene ID 1407 are specified. For example, the image is extracted in the order of the shooting time of the images.
For example, an image having the oldest shooting date and time among images having the same scene ID is extracted for each scene ID, and the extracted images are extracted in order of shooting time.

  The imaging apparatus 100 should display the enlarged image (enlarged image data) in addition to the image list display when the scene of the image displays the print image selection screen using the information specified in step S604. It is determined whether it is a scene (step S605).

  The images of the screen on which the enlarged image is displayed are shown in FIG. 10, FIG. 12, and FIG. The screen images that do not display the enlarged image are shown in FIGS. 10 to 13 will be described later.

  The determination (determination) as to whether or not the enlarged image is to be displayed is performed using the information specified in step S604 and the information in the enlarged display flag table 1500 shown in FIG. The enlarged display flag table 1500 includes a shooting mode 1501, an enlarged display flag 1502 (display setting information for each scene type), and the like. The shooting mode 1501 indicates a shooting mode applied during shooting.

  The enlarged display flag 1502 is a flag indicating whether an enlarged image should be displayed when an image shot in any shooting mode is displayed on the display screen for each scene. When the enlarged display flag 1502 = 1, on the screen for selecting a print image, not only a list of thumbnails but also an enlarged image of the thumbnail image is displayed. When the enlarged display flag 1502 = 0, a list of thumbnails is displayed on the screen for selecting a print image.

  For example, if thumbnails of images shot in portrait shooting mode are displayed as a list, the face images in the thumbnails are small, and it is difficult for the user to determine the appearance of the subject's face, so an enlarged image is displayed on the display screen, The user can easily select a print image.

  On the other hand, for example, when displaying an image that does not require confirmation of a detailed image compared to an image including a person when selecting a print image such as an image shot in landscape shooting mode, the display area is By displaying only a list of thumbnails on the display screen without displaying an enlarged image to be pressed, more images can be displayed on the display screen, and selection of images can be facilitated.

  When it is determined in step S605 that the enlarged image is a scene to be displayed (YES in step S605), the imaging apparatus 100 moves the process to step S611, and displays an image corresponding to the scene ID of the scene in FIG. Is displayed on the display screen using a screen such as the print image registration screen 1000 (step S611). That is, an image having the same scene ID as the image extracted in step S604 is extracted from a storage medium such as a memory card and displayed on the display screen.

  Here, an example of the configuration of the print image registration screen in the embodiment of the present invention will be described with reference to FIG. FIG. 10 is a diagram showing an example of the configuration of a print image registration screen in the embodiment of the present invention.

  As shown in FIG. 10, the print image registration screen 1000 includes a registered image display area 1001, a thumbnail image list display area 1002, a thumbnail image 1003, a selected image 1004, an enlarged image 1005, a previous scene representative image 1006, and a next scene representative image 1007. , “Return” button 1008, “Multiple selection” button 1009, “Done” button 1010, and the like.

  A registered image display area 1001 is a display area of an image registered as a print image (selected as a print image) (selected image display area display means). A thumbnail image list display area 1002 is a list display area of thumbnail images 1003 as selection candidates.

  The selected image 1004 is a thumbnail image 1003 and is an image that is being selected in accordance with a user operation instruction in order to display the enlarged image 1005 as an enlarged image. The previous scene representative image 1006 is a representative image of scenes displayed as a list on the display screen before the scenes displayed as a list on the print image registration screen 1000.

  The next scene representative image 1007 is a representative image of a group of scene images to be displayed as a list after a print image is registered from the scene images displayed on the print image registration screen 1000 (displayed images). .

A “return” button 1008 is a button for transitioning the display screen to a screen before the print image registration screen 1000 is displayed. A “multiple selection” button 1009 is a button for registering a plurality of images from one scene as print images at a time. A “complete” button 1010 is a button for completing registration of a print image.
When the selected image 1004 is changed by a user tap operation (tap instruction) or the like, the display of the enlarged image 1005 is also switched according to the change.

  Also, an instruction (registration instruction as a print image) for moving the enlargement image 1005 to the registration image display area 1001 by a tap operation (registration instruction as a print image) or a drag-and-drop operation on the enlargement display image 1005. If accepted, the enlarged image 1005 is registered as one of the print images, and the display screen display is transitioned to the image list screen (print image registration screen) of the scene to which the next scene representative image 1007 belongs.

  Upon transition of the display screen, the imaging apparatus 100 acquires information on the shooting mode of the next scene representative image 1007 and determines whether the scene to which the next scene representative image 1007 belongs is a scene on which an enlarged image is to be displayed. Then, a print image registration screen corresponding to the determination result is displayed on the display screen.

  The print image registration screen 1020 is a print image registration screen that is displayed when it is determined that the scene to which the next scene representative image 1007 belongs is not a scene in which an enlarged image is to be displayed.

In the print image registration screen 1020, the registration image display area 1021, the thumbnail image list display area 1022, and the thumbnail image 1023 are the same as those in the print image registration screen 1000.
The registered print image 1024 is an image instructed to be registered as a print image in the scene image group displayed on the print image registration screen 1000.

  In the print image registration screen 1020, when a tap operation on the thumbnail image 1023 is received, the image that is the target of the tap operation is registered as a print image. Also, when an instruction to move an image to the registered image display area 1021 is received by a tap operation drag and drop operation on the thumbnail image 1023, the image to be operated is registered as a print image. Details of the print image registration process will be described later with reference to FIG.

  When the print image is registered, the imaging apparatus 100 operates to display an image group of the next scene on the display screen, and repeats this. The above is an example of the configuration of the print image registration screen in the embodiment of the present invention shown in FIG.

  Returning to the description of FIG. The imaging apparatus 100 determines whether a selection instruction for the thumbnail image 1003 has been received on the print image registration screen 1000 displayed in step S611 (step S612), and determines that the selection instruction has not been received (NO in step S612). The process proceeds to step S613.

  If it is determined that a selection instruction has been received (YES in step S612), the display of the enlarged image 1005 is updated (step S613), and it is determined whether an instruction for the enlarged image 1005 has been received (step S614).

  If it is determined that an instruction for the enlarged image 1005 has not been received (NO in step S614), the process proceeds to step S617 to determine whether an instruction to complete registration of the print image has been received (step S617). That is, it is determined whether an instruction to press the “complete” button 1010 has been received.

  If it is determined that an instruction to complete registration of the print image has not been received (NO in step S617), the process returns to step S605. If it is determined that an instruction to complete registration of the print image has been received (YES in step S617), the process ends.

  Here, the registration of the print image is executed when the pressing of the “complete” button 1010 is accepted. For example, after the pressing of the “complete” button 1010 is accepted, the registration confirmation screen 900 of FIG. When the user presses the “Cancel” button 901, the display screen is returned to the print image registration screen 1000 without executing the registration process, and the user presses the “OK” button 902. In this case, registration of a print image may be executed for the first time.

  On the other hand, if it is determined in step S614 that an instruction for the enlarged image 1005 has been received (YES in step S614), the image that has received the instruction is registered as a print image (step S615). Specifically, the image is copied to a folder for storing the image to be printed (print image storage means).

  The folder for the print image is generated on a storage medium such as a memory card by the imaging device 100 when the registration of the print image is performed for the first time (print image folder generation means). Thereafter, an image registered as a print image is copied to the folder for the print image.

  Further, for example, in a photo printing machine that connects a memory card to extract an image in the memory card and causes the user to select an image to be displayed and printed on the display screen, a specific folder (for example, : Folder name = DCIM) is extracted and displayed on the display screen. In this case, the imaging apparatus 100 is a folder that is not the printing folder and stores the image. The folder name is changed to a folder name different from DCIM, and a folder for print images is generated as folder name = DCIM. Note that the method for securing the print image folder is not limited to this, and it is only necessary to distinguish between the print image folder and the non-print image folder.

  The imaging apparatus 100 displays the image registered as the print image (the image stored in the print image folder) in the registered image display area 1001 (step S616), and the print image is registered for all scenes. It is determined whether it is present (step S610). For example, all the scene IDs corresponding to the images stored in the memory card are extracted, and all the scene IDs are compared with the scene IDs of the images registered as print images. Whether or not is registered.

  If it is determined that no print image has been registered for all scenes (NO in step S610), the process proceeds to step S605. If it is determined that the print image has been registered for all scenes (YES in step S610), the process proceeds to step S617.

If the imaging apparatus 100 determines in step S605 that the scene is not a scene to display an enlarged image (NO in step S605), the imaging apparatus 100 proceeds to step S606 and displays a screen such as the print image registration screen 1100 in FIG. It is displayed on the screen (step S606).
