Description

  The present invention relates to an image display device, an image display method, and a program that individually display a plurality of series of images.

  In general, an auto bracket shooting function provided in an image pickup apparatus such as a digital still camera performs multiple high-speed shooting based on a reference value of a shooting parameter (for example, exposure, white balance, etc.) and a value obtained by changing the reference value. Are performed continuously. The shooting parameters for the auto bracket shooting function are not limited to one type, but, for example, as shown in Patent Document 1, a plurality of types of shooting arbitrarily selected from white balance, exposure, saturation, sharpness, etc. A technique is known in which a plurality of shootings are continuously performed while changing parameter values.

FIG. 2 is a diagram showing a parameter selection screen for arbitrarily selecting the type of shooting parameter, the reference value, the swing width, and the number of shots as a change condition regarding the shooting parameter for the bracket shooting function.
The illustrated example shows a case where two types of shooting parameters are selected for the bracket shooting function, and two desired shooting parameters are selected by a user operation from a parameter selection screen that displays a list of various shooting parameters. Shows the case. After the user selects a shooting parameter, the user changes the values before and after the reference value (for example, an automatically determined value determined by an autofocus (AF) function or a preset fixed value) for each shooting parameter. The operation of selecting the change width (the swing width) to be performed, or the operation of selecting the number of images to be continuously shot during bracket shooting. Note that three or more types of shooting parameters may be selected as the shooting parameters.

  In the example shown in the figure, “Exposure (EV)”, “Aperture”, “Shutter Speed”, “White Balance”, “Saturation”, and “Contrast” are displayed in a list on the parameter selection screen as shooting parameter selection candidates. However, the present invention is not limited to this. For example, a list including shooting parameters such as sharpness, ISO sensitivity, and flash may be displayed. In the figure, hatched items indicate items selected by user operations (hereinafter the same), and cases where “exposure (EV)” and “saturation” are selected as two types of shooting parameters. Yes.

  The illustrated example shows a screen for selecting an exposure parameter amplitude and a screen for selecting a saturation parameter amplitude as selection screens for selecting a shooting parameter amplitude. The case where “± 2 EV” is selected as an arbitrary swing width from the items “± 1 EV”, “± 2 EV”, and “± 3 EV” displayed in the list is illustrated. When “± 20%” is selected as an arbitrary amplitude from the “± 20%”, “± 50%”, and “± 70%” items listed on the saturation parameter screen. Illustrated. In addition, the selection screen for selecting the number of shots displays a list of items “3”, “5”, and “7” as selection candidates for the number of shots. The case where “3 sheets” is selected is illustrated. When selecting a desired item from the selection candidates, in the illustrated example, the up / down key of the cross key K3 is operated, and when the selection candidate is determined, the determination key (SET) K4 is operated. Yes.

  FIG. 3 is a diagram showing a plurality of images (a series of images) captured by bracketing according to two types of shooting parameters. “Exposure” and “Saturation” are set as the two types of shooting parameters, and the exposures are shown. “± 1 EV” is set as the number of shots, “3” is set as the number of shots, “± 20%” is set as the width of saturation, and “3” is set as the number of shots. It is a series of images obtained by bracket photography. In this case, a series of nine images in total is obtained by continuous shooting of a plurality of (three each) shooting parameter values of “exposure” and “saturation” by one shutter operation. In the figure, P1 to P9 are images sequentially taken at the time of bracket shooting, and a total of nine images (series of exposure parameters AE, + 2EV, -2EV and saturation parameters ± 0, + 20%, -20%). Image).

  The first image P1 shows an image shot under the conditions of “exposure = AE, saturation = ± 0”, and the second image P2 is shot under the conditions of “exposure = + 2 EV, saturation = ± 0”. Is shown. Similarly, the third image P3 is an image captured under the condition “exposure = −2EV, saturation = ± 0”, and the fourth image P4 is an image captured under the condition “exposure = AE, saturation = + 20%”. Is shown. Further, the fifth image P5 is photographed under the conditions of “exposure = + 2 EV, saturation = + 20%”,..., And the ninth image P9 is photographed under the conditions of “exposure = −2 EV, saturation = −20%”. Is shown. In the series of images, as information for identifying each of the images, a group flag “GF” indicating that the series is a series of bracketed pictures, and the series of pictures taken by the bracket belong to the same group. A group ID “Gid” for identifying this and a parameter ID “Pid” for bracket shooting are added. Details of the group flag “GF” and the parameter ID “Pid” will be described later.

  FIG. 4 shows an arrangement state when a series of bracket-captured images are virtually two-dimensionally arranged (biaxial arrangement). FIG. 4A shows two types of imaging parameters “exposure” and “saturation”. "And the number of shots" 3 "is set, and a series of images (9 images) when bracket shooting is performed is shown according to the two types of shooting parameters. ing. In this case, the first image P1 “exposure = AE, saturation = ± 0” shown in FIG. 2B is the center, and the second image P2 “exposure = + 2EV, saturation = ± 0 ”is arranged, the third image P3“ exposure = −2EV, saturation = ± 0 ”is arranged on the left, and the fourth image P4“ exposure = AE, saturation = + 20 ”is arranged on the left. % ”Is arranged, and the fifth image P5“ exposure = AE, saturation = −20% ”,... Is arranged below.

  Here, in the drawing, the parameter “Pid” indicates a parameter ID for bracket shooting, and in the XY coordinate system (two-dimensional coordinate system: two-axis coordinate system), the first shooting parameter is the X-axis direction, the second Assuming that the imaging parameter is the Y-axis direction, the arrangement position of each image is represented by (X, Y), and “Pid = 0, 0” indicates an image arranged at the center position of the arrangement. Then, the arrangement position of the image shifted by one step to the plus side of the image of “Pid = 0, 0” is represented by “+1”, and the arrangement position of the image moved by one step to the minus side is represented by “−1”. ing. Therefore, the arrangement position of the first image P1 shown in FIG. 2B is “Pid = 0, 0”, and the arrangement position of the second image P2 is “Pid = + 1, 0”. The arrangement position of the third image P3 is “Pid = −1, 0”, the arrangement position of the fourth image P4 is “Pid = 0, + 1”, and the arrangement position of the fifth image P5 is “Pid = 0, −1”,...

  FIG. 4 (2) shows a 5 × 5 two-dimensional array of a series of images (25 images) captured by bracketing when “5 images” is set as the number of images to be captured, according to two types of imaging parameters. It is the figure which showed the state which carried out. In this case, the arrangement position of each image is centered on “Pid = 0, 0”, the upper right position of the arrangement is “Pid = + 2, +2”, the lower right position is “Pid = + 2, −2”, and the upper left position. Becomes “Pid = −2, +2”, and the lower left position becomes “Pid = −2, −2”. Such an array position (X, Y) of each image is added together with “shooting date”, “title”, and the like as header information (various information about the image) of the image file.

FIG. 5 is a diagram for explaining a feed operation when a desired image is selected and individually displayed in the captured image reproduction mode.
FIG. 5 (1) shows a case where each image is individually selected and displayed in a state where a normal imaged (single imaged) image and a series of bracketed images are recorded and stored in a mixed order. It is a figure for demonstrating the feed operation to be performed. In the figure, since the group flag “GF” is added to the image file as header information, the control unit 1 is an image taken based on the group flag “GF” or bracketed. It is determined whether it is an image. Note that “GF = NO” indicates that the image is a single image, and “GF = YES” indicates that the image is a bracket image.

  The illustrated example shows a case where the cross key K3 is used as an image advance key and the image is forwarded in the forward direction by operating the right key. In this example, when the right key of the cross key K3 is operated once in a state where a single shot image is displayed, the image is switched to a bracket shot image (initially a representative image described later), Furthermore, when the right key is operated once, the next single-image shooting switching display is shown. As described above, in the present embodiment, in the state where a plurality of bracketed images and a single image are recorded and stored together, the same operation as that for sending a single image 1 is performed. With multiple key operations, a plurality of bracketed images are grouped as a unit.

  The representative image of bracket shooting is a central image whose arrangement position is “Pid = 0, 0”, but the representative image may be arbitrarily selected and set by a user operation. During the display of the representative image, a predetermined mark “SET” is synthesized and displayed on the representative image. That is, the mark “SET” for guiding that the determination key (SET) K4 should be operated is displayed on the representative image in order to be able to switch to another image other than the representative image in the series of images photographed by bracketing. Composite display.

FIG. 5 (2) is a diagram for explaining a parameter-by-parameter feed operation for displaying each image of bracket shooting individually for each shooting parameter.
FIG. 5 (2) shows a series of images taken with brackets in a state where “exposure” and “saturation” are set as two types of shooting parameters and “3” is set as the number of shots. Among the nine images), the representative image “Pid = 0, 0” (exposure = AE, saturation = ± 0) is displayed. Here, when a parameter-by-parameter feed operation (up / down / left / right key operation) is performed using the cross key K3, the arrangement position of the currently displayed image (initially a representative image) is set as the starting point, and the image is moved from that starting point to the parameter-by-parameter feed operation. I am trying to feed. That is, when a parameter-specific operation using the cross key K3 is performed, an image captured with a parameter value of a type corresponding to the operation among two types of shooting parameters when the currently displayed image is captured is displayed. It is specified and switched for display.

  As described above, in this embodiment, the arrangement position of the displayed image (initially representative image) is used as a starting point, and image feed is performed from that starting point. In this case, in order to clearly indicate how many images are arranged in the image feed direction starting from the displayed image, information regarding the arrangement state is displayed in an identifiable manner for each direction. That is, as an index for clearly indicating the number of images that can be fed from the starting position of the arrangement position of the displayed image, it corresponds to a plurality of directions (the arrangement direction of the images). Thus, information relating to the arrangement state of a series of images photographed by bracketing is displayed in an identifiable manner.

  Information related to the arrangement state of a series of images (an index that clearly indicates the number of images that can be fed) is information that is identifiable behind the image being displayed. Is used as an index to display the images that are superimposed and displayed as many images as possible while shifting the display position so that one end (one end) protrudes from the displayed image. The number is the number of images that can be fed. In this way, an index for clearly indicating an image that can be fed in each direction is displayed in an identifiable manner (overlapping display). For example, in the example shown in the figure, the number of images that can be moved in the up / down / left / right directions is “1”. Therefore, behind the image being displayed, one image is displayed on the four sides. Therefore, it is clearly indicated that the number of images that can be fed in that direction is “1”.

  When an image of “Pid = 0, 0” (exposure = AE, saturation = ± 0) is displayed as a representative image of bracket shooting, if any of the up / down / left / right keys of the cross key K3 is operated, The control unit 1 specifies the next image arranged in the direction of the key operation as a display target and performs switching display (individual display). In the figure, “Exposure +” added to the margin indicates that the right key is the forward key for the exposure parameter, and “Exposure-” indicates that the left key is the reverse key for the exposure parameter. “Saturation +” indicates that the up key is a forward key for the saturation parameter, and “saturation−” indicates that the down key is a reverse key for the saturation parameter.

  That is, for example, when the right key is operated once, the image is moved forward in the plus direction of the exposure parameter to switch and display an image that is shaken by one step (an image of “Pid = + 1, 0”), and the left key is When operated once, the image is fed in the negative direction of the exposure parameter to switch and display an image that has been shaken by one step (an image of “Pid = −1, 0”). When the up key is operated once, the image is forwarded in the plus direction of the saturation parameter to switch and display an image that has been shaken by one step (an image of “Pid = 0, + 1”). When the operation is performed twice, the image is fed in the direction of the minus value of the saturation parameter, and the image is switched and displayed in an image shaken by one step (an image of “Pid = 0, −1”). In the display state shown in FIG. 5 (2), when the enter key (SET) K4 is operated again, the display state returns to the state shown in FIG. 5 (1), and a single-captured image can be displayed. .

  Further, as shown in FIG. 5 (2), on the screen on which the display target images are individually displayed, the displayed image (initially representative image) is arranged at any position in the two-dimensional array. An array image MT for guiding whether or not the image is arranged is displayed on a part of the screen (lower right corner in the illustrated example). In the illustrated example, a 3 × 3 grid (matrix) array image MT is shown. The grid at the center position indicates the array position of the displayed image, and the grid at this position is identified. Displayed (hatched). This identification display (hatched display) is changed to a grid corresponding to the arrangement position every time the image being displayed is switched, and an image display that clearly shows the arrangement position of the image being displayed is displayed. Note that the display position of the array image MT is not limited to an individual display image, and is arbitrary. Further, the display presence / absence of the array image MT may be switched.

FIG. 6 is a diagram showing a display state when an image is sent by one step in the vertical and horizontal directions centering on an image (representative image) of “Pid = 0, 0”.
When the image is fed to the right by a single right key operation while the representative image is displayed, the image is switched to the image “Pid = + 1, 0”. An image with “Pid = + 1, +1” exists further upward in the image, an image with “Pid = + 1, −1” exists in the lower direction, and “Pid = −1, 0” exists in the left direction. And an image of “Pid = 0, 0” are present, and an index for clearly indicating the number of images that can be fed in each direction is identified and displayed (overlapping display).

  Similarly, when the representative image is displayed and the image is fed to the left by one left key operation, the image is switched to the image “Pid = −1, 0”. An image of “Pid = −1, +1” in the upper direction of the displayed image, an image of “Pid = −1, −1” in the lower direction, and an image of “Pid = 0, 0” in the right direction In addition, since an image of “Pid = + 1, 0” exists, an index for clearly indicating the number of images that can be fed in each direction is displayed. In addition, the number of images that can be sent in each direction is clearly indicated even when the image is switched to the “Pid = 0, −1” image or the image is switched to the “Pid = 0, +1” image. The indicator for doing is displayed.

FIG. 7 is a diagram for explaining the scene-specific bracket A table 3d, and FIG. 8 is a diagram for explaining the scene-specific bracket B table 3e.
The scene-specific bracket A table 3d and the scene-specific bracket B table 3e are shooting scenes arbitrarily selected by a user operation from various shooting scenes set according to how and what kind of subject is shot. Is a table that is referred to when bracket shooting is performed in accordance with each of the various shooting scenes, and changes related to shooting parameters for the bracket shooting function (type of shooting parameter, reference value, amplitude, shooting Number of sheets) is stored.

  As shown in FIG. 7, the scene-specific bracket A table 3d includes items of “scene”, “parameter”, “parameter reference value (fixed)”, “parameter swing width (fixed)”, and “number of sheets”. The contents of which are fixed tables that cannot be changed by user operations. “Scene” is an item for storing a name indicating a shooting scene. For example, “Shooting petals with attention to focus position (fixed)”, “Shooting food with focus position (fixed)”,. “Shooting with attention to color and brightness indoors (fixed)” is stored. Here, “(Fixed)” in “Scene” means that the contents of “Parameter Reference Value (Fixed)”, “Parameter Width (Fixed)”, and “Number of Sheets” described later cannot be changed. It means that the content is typical.

  “Parameter”, “Parameter reference value (fixed)”, “Parameter amplitude (fixed)”, and “Number of sheets” are items indicating change conditions related to the shooting parameters for the bracket shooting function. “Parameter” stores a parameter name indicating the type of shooting parameter for the bracket shooting function, and a plurality of types of parameter names can be stored in association with one shooting scene. For example, in the “parameter” item corresponding to the shooting scene, one type of shooting parameter “focus” is stored corresponding to “shooting (fixing) the petal with attention to the focus position”, and so on. Two types of shooting parameters “white balance” and “exposure (EV)” are stored corresponding to “shoot with attention to taste (fixed)” and “shoot with attention to color and brightness indoors (fixed)” Has been.

  “Parameter reference value (fixed)” uses an automatically determined value determined by autofocus (AF), auto exposure (AE) function, auto white balance (AWB) function, or the like as a parameter reference value for bracket shooting. Or an information that indicates whether to use a preset fixed value (for example, a value set before product shipment). In the figure, the AF value, AE value, and AWB value are automatically determined. “Middle position”, “Middle value”, “No filter”, “4000K” indicates that a fixed value should be used, and its contents cannot be changed. It is a content. The control unit 1 refers to the scene-specific bracket A table 3d according to the shooting scene selected by the user operation, and acquires the automatically determined value or the fixed value as the reference value of the shooting parameter.

  “Parameter swing width (fixed)” is an item for storing, as a fixed value, a change width (switch width) that changes the reference value of the imaging parameter before and after. For example, when “scene” is “photographed with focus on petal focus (fixed)”, “parameter” is “focus”, and “parameter reference value (fixed)” is “AF value”, “parameter” “± 5 cm” is stored as “the swing width (fixed)”, and indicates that the reference value “AF value” should be changed by 5 cm before and after the reference value “AF value”. In addition, when “Scene” is “photographed indoors with attention to color and brightness (fixed)”, “white balance” and “EV” are stored as two types of “parameters”, and corresponding to them. “Parameter temperature (fixed)” is “4000K”, “AE value”, “Parameter amplitude (fixed)” is stored as “Color temperature = ± 1000K”, “± 1EV”, and the reference value is “4000K”. “1000” before and after that, and 1 EV before and after that, based on the reference value “AE value”. “Number of sheets” is an item for storing the number of shots that are continuously taken a plurality of times while changing the shooting parameters as a change condition for the shooting parameters. For example, “3”, “5”, etc. are stored. ing.

  As shown in FIG. 8, the scene-specific bracket B table 3e includes items of “scene”, “parameter”, “parameter reference value (fixed / variable)”, “parameter swing width (variable)”, and “number of sheets”. It is a variable table whose contents can be arbitrarily changed by a user operation. “Scene” is an item for storing a name indicating a shooting scene, and “(variable)” in this scene means “parameter reference value (fixed / variable)” and “parameter amplitude (variable)” described later. ”And“ number of sheets ”means that the user can arbitrarily change the contents.

  “Parameter”, “Parameter reference value (fixed / variable)”, “Parameter amplitude (variable)”, and “Number of sheets” indicate changing conditions related to the shooting parameters for the bracket shooting function. The “parameter” can store two types of shooting parameters such as “saturation” and “contrast” in association with one shooting scene. “Parameter reference value (fixed / variable)” is an item indicating whether to use an automatically determined value, a preset fixed value, or a specified value that is arbitrarily specified. , AE value, AWB value indicate automatically determined values, intermediate position, intermediate value indicates a fixed value, “3000K / 4000K / 5000K” indicates a plurality of candidate values, and any of them can be arbitrarily selected by a user operation. The specified value becomes a specified value (for example, 4000K).

“Parameter swing width (variable)” is an item that stores a change width (width) that changes before and after the reference value of the shooting parameter, and is arbitrarily specified by a user operation from a plurality of candidate values. The value is the swing width. For example, if “scene” is “photographed with focus on petal focus ( variable )” and “parameter” is “focus”, a plurality of candidate values of “parameter swing width (variable)” “ An arbitrary swing width (for example, ± 20 cm) can be selected as a designated value from among “± 5 cm / ± 20 cm / ± 50 cm” by a user operation.

  As described above, the scene-specific bracket A table 3d and the scene-specific bracket B table 3e are used when bracket shooting is performed in accordance with the shooting scene, and an arbitrary scene is selected from various shooting scenes by a user operation. Then, the control unit 1 acquires the change condition regarding the shooting parameter corresponding to the shooting scene by referring to the corresponding table (the scene-specific bracket A table 3d or the scene-specific bracket B table 3e). It is set to perform bracket shooting.

  As described above, in the embodiment, the image display apparatus (digital camera) corresponds to a plurality of types of shooting parameters (for example, exposure and saturation), and changes the parameter value for each type of the parameter while changing a plurality of the same subjects. An acquisition means (control unit 1, program memory 3a) for acquiring a series of images taken once (a series of images taken with brackets), and one of the images taken of the same subject acquired by the acquisition means are displayed. Display means (control unit 1, program memory 3a, display unit 5) to be changed, and change operation means (corresponding to the plurality of types of imaging parameters and capable of performing parameter-specific operations for changing the parameter value for each type) When the control unit 1, the program memory 3a, the cross key K3) and the parameter-specific operation by the change operation unit are performed, the display unit displays An image photographed with a photographing parameter obtained by changing the parameter value of the kind of photographing parameter corresponding to the operation among a plurality of kinds of photographing parameters at the time of photographing an image is identified from among a series of images obtained by the obtaining means Specifying means (control unit 1, program memory 3a) and switching means (control unit 1, program memory 3a) for switching the displayed image displayed on the display means to the image specified by the specifying means 3a).

Next, the operation concept of the image display apparatus (digital camera) in the present embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. Further, it is possible to sequentially execute the operation according to the above-described program code transmitted via a transmission medium such as a network. In other words, in addition to the recording medium, an operation unique to the present embodiment can be executed using a program / data supplied externally via a transmission medium.

9 to 12 are flowcharts for explaining the operation (characteristic operation of the present embodiment) of the image display apparatus (digital camera) that is started in response to power-on.
First, the control unit 1 executes an initialization process (step S1 in FIG. 9) for clearing a memory or the like in response to a power-on operation, and then checks whether it is a bracket shooting setting mode (step S2) or is stationary. Whether it is the image shooting mode (step S15 in FIG. 10) or whether it is in the still image reproduction mode is checked (step S28 in FIG. 11). Here, if the operation mode is other motion mode such as the moving image shooting mode (NO in step S28 in FIG. 11), processing according to the other mode, for example, processing for setting shooting conditions other than bracket shooting. Then, a process of shooting a moving image is performed (step S29), and the process proceeds to step S2 in FIG.

  If the mode is switched to the bracket shooting setting mode (YES in step S2 in FIG. 9), it is checked whether the setting for the scene-specific bracket B table 3e is instructed by the user operation as the setting type (step S2). S3) When setting by scene is instructed (YES in step S3), when an arbitrary scene is selected by user operation from a list screen of various shooting scenes (step S4), the selected scene is selected. Correspondingly, the process proceeds to the process of setting the change condition relating to the change of the bracket shooting parameter in the scene-specific bracket B table 3e (steps S5 to A8).

  That is, an operation for selecting up to two types of shooting parameters from a screen for displaying a list of types of shooting parameters is performed (step S5), and thereafter an operation for selecting the reference value and the amplitude for each selection parameter. When the operation is performed (step S6) and an operation for selecting the number of shots is performed (step S7), the control unit 1 changes the change condition (the type of the selected parameter, the reference value, the change) corresponding to each selected scene. A process of setting the width and the number of shots in the scene-specific bracket B table 3e is performed (step S8). Here, in the case of setting to “parameter reference value (fixed / variable)”, an arbitrary item is selected from the automatically determined value / fixed value / specified value. An arbitrary value is selected from among the candidate values by user operation. Further, the number of shots may be set for each shooting parameter or may be set for each scene.

  Then, in order to arbitrarily associate the two types of shooting parameters selected as described above with the image feed direction (image arrangement direction), up to the two types selected in the XY coordinate system (two-dimensional coordinate system). One of the shooting parameters is set as the first parameter, the arrangement position of the first parameter is selected as “X”, the other is set as the second parameter, and the arrangement position of the second parameter is set as the second parameter. After performing the process of selecting “Y” (step S9), the process returns to step S2. When the selected shooting parameter is one type, “X” is set as the first parameter.

  Further, in the bracket shooting setting mode (YES in step S2), if the setting for each scene is not specified (NO in step S3), the process proceeds to a process of sequentially setting change conditions relating to changes in bracket shooting parameters (step S10). To S14). That is, in the state in which the parameter selection screen shown in FIG. 2 is displayed (step S10), after an operation (step S11) for selecting two types of shooting parameters from the screen is performed, the reference for each selected parameter is displayed. When an operation for selecting a value and a swing width is performed (step S12), and an operation for selecting the number of shots is performed (step S13), the selected parameter type, reference value, swing width, and number of shots are selected. A process of setting the photographing condition in the imaging unit 6 or the like is performed (step S14). Note that the number of shots may be set for each shooting parameter. One of the two types of imaging parameters is set as the first parameter, the arrangement position of the first parameter is selected as “X”, the other is set as the second parameter, and the second parameter After performing the process of selecting the array position as “Y” (step S9), the process returns to step S2. Also in this case, when the selected shooting parameter is one type, “X” is set as the first parameter.

  On the other hand, when the mode is switched to the still image shooting mode (YES in step S15 in FIG. 10), it is checked whether the bracket shooting function is turned on (step S16), and the function is turned on. If so (YES in step S16), it is checked whether bracket shooting for each scene is designated by a predetermined operation (step S17). If bracket shooting for each scene is designated (YES in step S17), the process proceeds to processing for displaying a scene selection screen (menu screen) for displaying a list of sample images for each scene for bracket shooting (step S18). .

  FIG. 13 is a diagram illustrating a scene selection screen (menu screen) displayed prior to bracket shooting. This scene selection screen is a screen for the user to select an arbitrary shooting scene from various shooting scenes. This screen displays the parameters for bracket shooting corresponding to the scenes for the various shooting scenes. A list of sample images in the case where the images were taken in is displayed. In the figure, “(fixed)” indicates a sample image generated according to the contents of the scene-specific bracket A table 3d, and “(variable)” indicates the contents of the scene-specific bracket B table 3e. It shows that the sample image is generated. The sample images displayed in the scene selection screen in this way are thumbnail images of the same size and arranged in a matrix. In the example shown in the figure, the contents of the scene-specific bracket A table 3d and the contents of the scene-specific bracket B table 3e are mixedly displayed, but they may be displayed separately as a list. The scene selection screen may display a list of scene names in combination with the sample images.

  When an arbitrary shooting scene is selected from the bracket shooting scene selection screen (step S19), the change condition relating to the shooting parameter corresponding to the selected scene is set as the scene-specific bracket A table 3d or the scene-specific bracket B table 3e. (Step S20) and temporarily stored in the work memory 3b (step S21). In this state, when the shutter key K2 is operated (YES in step S22), bracket shooting is started, and the number of shots is changed while changing the shooting parameter value corresponding to the scene according to the change condition regarding the shooting parameter in the work memory 3b. Minutes of continuous shooting is performed (step S23).

  As a result, a group flag “GF” indicating that a series of images captured by bracket shooting is used as information for identifying bracket shooting in the header information of each image file. "A group ID" Gid "for identifying that a series of bracketed images belong to the same group and a bracket shooting parameter ID" Pid "are respectively added (step S24). In this case, “GF = YES” is added as the group flag, and “Gid =” 1 is added as the group ID, for example. Then, it returns to step S2 of FIG.

  In the still image shooting mode (YES in step S15), when the shutter key K2 is operated (YES in step S25) when the bracket shooting function is turned off (NO in step S16), the setting is made. One image is shot according to the set shooting conditions (step S26). Then, compression processing is performed on the captured image of one image, or a group flag “GF” is added to the header information of the image file as information for identifying single image capturing (step S27). In this case, “GF = NO” is added as a group flag. Then, it returns to step S2 of FIG.

  On the other hand, when the mode is switched to the still image playback mode (YES in step S28 in FIG. 11), when a date, a title, or the like is input by a user operation to specify a playback target, an image corresponding to the input information is displayed. A folder is selected as a playback target (step S30), and the first image file is selected and acquired from the image folder as a playback target (step S31). Then, it is checked whether the group flag GF of the image selected and acquired as the reproduction target is “NO”, that is, whether the image is a single image (step S32). Here, since the first image shown in FIG. 5A is a group flag “GF = NO”, that is, an image of a single image (YES in step S32), the image is normally displayed individually. The process proceeds to (display one sheet) (step S33).

  Then, it is checked whether or not the cross key K3 as the feed key has been operated (step S34), or whether or not the playback end operation for canceling the playback mode has been performed (step S35). If an end operation for canceling the playback mode is performed (YES in step S35), the process returns to step S2 in FIG. 9, but when the cross key K3 is operated to instruct the image advance in the shooting order (step S35). Based on the type of the operation key, the feed direction (for example, the left-right direction) is determined (step S36), and it is checked whether there is an image in the determined direction (step S37).

  If there is no image in the determined direction (NO in step S37), the process returns to the above-described step S34 in order to ignore the current feeding operation, but if there is an image in the determined direction (YES in step S37). The image in the feeding direction is selected and acquired as a reproduction target (step S38). In this case, when the right key of the cross key K3 is operated, the next image in the forward direction with respect to the image being displayed is acquired as a reproduction target, and when the left key is operated, the image being displayed is acquired. The next image in the reverse direction is selected and acquired as a playback target. Then, returning to the above-described step S32, every time it is determined whether the image selected and acquired as a reproduction target is a single-shot image (YES in step S32), The above operation (steps S33 to S38) is repeated.

  Now, assuming that the second image shown in FIG. 5A is selected as the reproduction target, the group flag of the image is “GF = YES”, that is, the bracketed image is designated as the reproduction target. Since this is the case (NO in step S32), the process proceeds to step S39 in FIG. 12, and processing is performed to virtually two-dimensionally arrange (X, Y array) each image (series of images) photographed by the bracket. In this case, by performing a process of virtually two-dimensionally arranging a series of images, for example, each image (a series of images) is arranged in a 3 × 3 matrix arrangement state as shown in FIG. A 5 × 5 matrix arrangement is obtained as shown in FIG.

  Then, an image arranged at the position of “Pid = 0, 0” at the center of the two-dimensional array is acquired as a representative image and individually displayed (step S40). Further, the above-described index display behind the representative image, that is, the number of images to be fed (the number of images that can be fed) is displayed as an index (overlapping display) (step S41). Then, a mark “SET” indicating that the decision key (SET) K4 should be operated is guided and displayed on the representative image (step S42). As a result, the display state as shown in FIG.

  In this state, it is checked whether or not the enter key (SET) K4 is operated (step S43). If the enter key (SET) K4 is not operated (NO in step S43), the process returns to step S34 in FIG. When (SET) K4 is operated (YES in step S43), the guide display mark “SET” is deleted (step S44), and the displayed image (in this case, the representative image) is displayed in the two-dimensional array. An array image MT for guiding the position of the array is arranged and displayed on a part of the screen (for example, the lower right corner) (step S45). As a result, the display state as shown in FIG.

  Here, it is checked whether display switching to a thumbnail list screen for displaying a list of each bracketed image is instructed by a user operation (step S46), or whether the cross key K3 as a feed key is operated (step S46). In step S50), it is checked again whether the enter key (SET) K4 has been operated (step S55). When the thumbnail list screen is instructed (YES in step S46), the screen is switched to a thumbnail list screen that displays a list of each bracketed image (step S47). In FIG. 14, as shown in FIG. 4A, bracket shooting is performed in a state where two types of shooting parameters “exposure” and “saturation” are set and the number of shots “3” is set. It is the figure which illustrated the thumbnail list screen of a series of images (9 images) in the case of the case. When an arbitrary image is selected as a display target by a user operation from the thumbnail list screen (YES in step S48), the process proceeds to step S53, and the selected image is switched to individual display. If NO in step S48, it is checked whether cancellation of the thumbnail list screen is instructed (step S49). If cancellation of the list screen is instructed (YES in step 49), the process returns to step S46 described above.

  On the other hand, when the cross key K3 as the feed key is operated (YES in step S50), the feed direction is determined according to the operation key (step S51). That is, it is checked which direction of up / down / left / right direction is instructed according to which of the up / down / left / right keys is operated. Then, starting from an image being displayed (for example, a representative image) in a series of images that are two-dimensionally arranged as described above, it is checked whether the next image is arranged in the feeding direction (step S52). If the next image does not exist (NO in step S52), the process returns to step S46 described above to invalidate the current feeding operation.

  If there is a next image in the instructed feed direction (YES in step S52), the image is acquired and individually displayed, and at which position in the two-dimensional array the image being displayed is arranged. The array image MT to be guided is arranged and displayed on a part of the screen (step S53). Further, behind the image being displayed, the number of images to be sent (number of images that can be fed) is displayed as an index (overlapping display) for each feeding direction (step S54). Thereafter, the process returns to step S46 described above. Thereafter, every time the cross key K3 as the feed key is operated (YES in step S50), the above-described operation (steps S51 to S54) is repeated.

  Thus, for example, when an image is sent in the vertical and horizontal directions in a state where an image (representative image) of “Pid = 0, 0” is displayed as shown in FIG. The next image is displayed individually. That is, the image is switched from the representative image to the “Pid = + 1, 0” image by the rightward feed operation, and is switched to the “Pid = −1,0” image by the leftward feed operation. Is switched to the image of “Pid = 0, −1” by the forward feed operation, and is switched to the image of “Pid = 0, +1” by the upward feed operation. Note that when a backward feed operation is performed, the display returns to the display of the original representative image at the position of “Pid = 0, 0”.

  Further, for example, in the state where the image of “Pid = + 1, 0” is displayed individually, there are two images in the left direction, so that “Pid = 0, 0” is performed by two image feed operations. ", And an image of" Pid = -1, 0 ". Similarly, in the state in which the images of “Pid = 0, −1” are individually displayed, there are two images in the upward direction, so that “Pid = 0, 0” is performed by two image feed operations. "" And an image of "Pid = 0, +1". Thereafter, the operation of the determination key (SET) K4 again (YES in step S57) returns to step S2 in FIG.

  As described above, in the embodiment, the control unit 1 corresponds to a plurality of types of shooting parameters, and when reproducing a series of images obtained by shooting the same subject a plurality of times while changing the parameter value for each parameter type, A plurality of types when an image being displayed on the display unit 5 is captured when an operation according to the parameter is performed with the cross key K3 that corresponds to a plurality of types of shooting parameters and changes the parameter value for each type. Since the image captured with the parameter value of the type corresponding to the operation is specified and displayed as a display target, many of the images are the same subject but only the shooting parameter value is slightly different. A desired image can be quickly found from the inside. That is, it is possible to individually display images photographed with the parameter value with an operation sense of changing the value of the photographing parameter for each type, and even when the user individually confirms the details of many images in detail. The confirmation work can be performed efficiently, and it is rich in operability and convenience.

  Since multiple shot images obtained by bracketing shooting that continuously performs multiple shots while changing multiple types of shooting parameters are acquired as a series of images, how to change the shooting parameters It is possible to visually confirm whether or not the photographed image changes, which is useful for improving photography skills.

  Since it is possible to arbitrarily set the correspondence between the type of shooting parameter and the operation according to the parameter, it is possible to send an image in consideration of the user's usability and the like, which is useful for improving the operability.

  Since the image to be displayed is specified so as not to change other shooting parameters and the subject other than the shooting parameters corresponding to the parameter-specific operation, the image can be fed according to the operation intended by the user.

  A series of images can be arranged in virtual multi-dimensions (multiple axes) according to multiple types of parameters, and an image can be sent from that starting point, starting from the array position of the displayed image in the series of images. Since the index for clearly indicating the image is identified and displayed, it is possible to instruct image feed while visually confirming the index display, and it is easy to understand visually.

  The direction in which the image can be fed starting from the displayed image is identified and displayed as an index, so that the direction in which the image can be fed can be known during parameter-specific operations, preventing unnecessary idle feeding operations. Can do.

  Since the number of images that can be moved from the displayed image is used as an index, the number of images that can be moved during parameter-specific operations can be identified, and wasteful skip operations can be performed. Can be prevented.

  In a state where a plurality of shot images taken with bracket shooting and a single shot image are stored together, bracket shooting was performed by one operation similar to the operation of sending a single shot image. Since multiple groups of shot images are sent as a group, the number of bracketed shots can be at most one feed operation, compared to sending bracketed images one by one for each feed operation. Thus, it is possible to smoothly feed the entire image including the single-shot image. Furthermore, for example, it is not necessary to divide the playback mode for single shooting and the playback mode for bracket shooting, and it is possible to easily find an image for bracket shooting.

  In the above-described embodiment, the operation for each parameter is performed using the cross key K3 for instructing the up, down, left, and right directions as the feeding operation at the time of reproduction. However, this is common with the operation for changing the shooting parameters at the time of shooting. It is desirable that Furthermore, an operation for each parameter may be performed by using a photographing parameter setting operator that changes the photographing parameter value and sets it as a photographing condition at the time of photographing. That is, for example, the exposure parameter may be an exposure correction dial, the zoom parameter may be a zoom ring, and the focus parameter may be a focus ring. In this way, operators for setting shooting parameters such as an exposure correction dial, a zoom ring, and a focus ring may also be used as parameter-specific operations during reproduction. As a result, when an image is reproduced, the same operation is performed using an operator that changes the value of the shooting parameter for each type, so that a desired image can be individually displayed with the same feeling as when shooting. Further, it may be a touch operation on the touch panel (flick operation, tap operation, etc.).

  In the above-described embodiment, the display position is shifted so that one end of the image that can be fed is projected behind the image being displayed, and the images are superimposed and displayed (overlapping display). However, in order to clearly indicate the number of images that can be fed in each direction, the number of images may be displayed numerically. FIGS. 15A and 15B are diagrams exemplifying a case where the number of images that can be fed is numerically displayed. Here, in correspondence with the four directions (up, down, left, and right) of the image being displayed, the number of images that can be fed in each direction is displayed numerically (index display). That is, as shown in the figure, rectangular labels are placed close to the top, bottom, left, and right sides of the image, and the number of images that can be fed in each direction is numerically displayed in the label.

  In FIG. 15A, the number of images that can be sent in the right direction starting from the displayed image is numerically displayed as “10”, and the number of images that can be sent in the left direction is as follows. This is a case in which “2”, the number of images that can be sent in the upward direction is “4”, and the number of images that can be sent in the downward direction is “8”. In this state, for example, when the left key of the cross key K3 is operated once, as shown in FIG. 15B, one image is sent in the left direction, and the left index display is “1”. Sheet "and the index display on the right is" 11 sheets ". In this way, when displaying information about the arrangement state of a plurality of images, if the number of images that can be fed in each direction is displayed numerically, for example, at most all of the images that can be fed Can be specified.

  FIG. 16A is a diagram for explaining a modification example in which a parameter name is displayed as an index display. A plus mark “1” indicating that the image being displayed is displayed in the parameter name as a starting point. FIG. 10 is a diagram illustrating a case where a plus mark “−” indicating that the feed is in the reverse direction is added and displayed. In the figure, “Exposure +” is an index indicating the forward direction of the exposure parameter, “Exposure −” is an index indicating the forward direction of the exposure parameter, and “Saturation +” is the saturation parameter. The forward feed, “saturation −” is an index indicating the feed of the saturation parameter in the reverse direction. FIG. 16B is a diagram showing a case where the parameter name including the feeding direction in FIG. 16A is added to the number of images that can be fed and displayed. In the example shown in the drawing, the image feed number of the exposure parameter is 10 sheets, the image feed number of the white balance parameter is 2 sheets, the image feed number of the saturation parameter is 4 sheets, and the image feed number of the aperture parameter, starting from the displayed image. Indicates 8 sheets.

In the embodiment described above, an example in which two types of shooting parameters are sent and displayed has been shown, but it is also possible to perform a feed operation with more types of shooting parameters.
FIG. 17A is a diagram illustrating a case where four types of shooting parameters are sent and displayed in four directions. That is, when displaying information on the arrangement state of a plurality of images by direction during reproduction, a plurality of feed directions and a plurality of types of parameters are associated with each other in a one-to-one correspondence with a plurality of feed directions. It is the figure which illustrated the case where it was made to display a different parameter name. Here, corresponding to the four directions (up, down, left, and right) of the image being displayed, the shooting parameter names are displayed for each direction. By displaying the parameter name for each direction in this way, for example, an image in which the parameter “exposure” is changed by feeding to the right with respect to the image being displayed is displayed, and the parameter “ An image in which the “WB (white balance)” changes is displayed, an image in which the parameter “saturation” changes by an upward feed, and an image in which the parameter “aperture” changes by a downward feed. Which indicates that.

  In this case, every time the cross key K3 as the feed key is operated, the control unit 1 seamlessly sequentially switches and displays each image corresponding to the number of images in that direction. For example, the next image (exposure = AE) is switched and displayed by the first operation of the right key for the currently displayed image (exposure = -2EV), and the next image (exposure = + 2EV) is displayed by the second operation. ), And the first image (exposure = −2EV) is switched and displayed by the third operation. In this way, when displaying information related to the arrangement state of a plurality of images as an indicator, if the shooting parameters are displayed in association with the feed direction, the parameters can be identified in the feed direction, which improves operability. Useful.

FIG. 17B is a diagram exemplifying a case where four types of imaging parameters and the feeding direction is eight directions. That is, four types of imaging parameters vertically, horizontally, diagram in which the imaging parameter name including a mark indicating the upper left oblique and lower right, the feed direction in association with each direction of the upper right and lower left FIG. In this case, in the displayed image, the left and right parameters are “exposure +” and “exposure −”, and the parameters in the upper right and lower left directions are “white balance (WB +)”, “(WB−)”, The parameters in the vertical direction are “saturation +” and “saturation −”, and the parameters in the upper left and lower right directions are “focus +” and “focus −”.

  In this case, the up / down / left / right parameters “exposure +”, “exposure−”, “saturation +”, and “saturation−” are fed by operating the corresponding up / down / left / right keys. The feeding of WB +, WB-, focus +, and focus- is performed by pressing two keys simultaneously. That is, the parameter “WB +” is fed by pressing the right key and the up key simultaneously, the “focus-” feed is pushed by the left key and the up key simultaneously, and “WB−” is fed by the left key and the down key. Simultaneously pressing and “Focus +” feed are performed by simultaneously pressing the right and down keys. In this way, when information regarding the arrangement state of a plurality of images is displayed by index according to direction, if a plurality of types (eight types) of shooting parameter names are displayed in association with eight directions, a variety of shooting parameters can be displayed. The changed bracketing image can be confirmed.

  In the above-described embodiment, the images captured by the bracket are exemplified as the plurality of images. However, the present invention is not limited to the bracket shooting, and the same applies to a plurality of images obtained by changing a plurality of types of shooting parameters by manual operation. It is applicable to. In this case, it is desirable to photograph while changing the parameter values sequentially at predetermined equal intervals by manual operation. However, there may be a case where there is a missing parameter value that is not photographed because of manual operation. In such a case, a new image may be generated from the image of the parameter value before and after that and the missing portion may be complemented.

  In the above-described embodiment, the case where the present invention is applied to a digital camera (imaging device) as an image display device that individually displays a plurality of images has been described. However, the present invention is not limited to a digital camera, but a personal computer, a PDA (personal portable information) The present invention can be applied to communication devices), tablet terminals, mobile phones such as smartphones, electronic games, music players, and the like.

  Further, the “apparatus” and “unit” shown in the above-described embodiments may be separated into a plurality of cases by function, and are not limited to a single case. In addition, each step described in the above-described flowchart is not limited to time-series processing, and a plurality of steps may be processed in parallel or separately.

The embodiment of the present invention has been described above. However, the present invention is not limited to this, and includes the invention described in the claims and the equivalent scope thereof.
