  Here, the setting of the auxiliary shooting line in the present embodiment will be described with reference to FIG. FIG. 6 shows a display example of a setting screen for performing settings relating to display. FIG. 6A shows a display example of the information display setting screen in the still image mode, and FIG. 6B shows a display example of the information display setting screen in the moving image mode. As shown in FIG. 6A, in the still image mode, a menu name 601 called shooting information display setting, and a switching setting (menu item 602) and grid setting (menu item) as menu items selectable in shooting information display setting. 603) is displayed. As shown in FIG. 6B, even in the moving image mode, the menu name 618 called shooting information display setting, and the same switching setting (menu item 619) and grid setting as the still image mode are selectable as menu items in the shooting information display setting. (Menu item 620) is displayed. The information display setting screens shown in FIGS. 6A and 6B are displayed on the display unit 28 by the same operation from the respective shooting standby states. However, items set as grid settings differ between the still image mode and the moving image mode. In this embodiment, what is set as the grid setting in the still image mode is the grid 1 indicated by the item 617 displayed on the right side of the menu item 602. On the other hand, the aspect ratio 2.35: 1 indicated by the item 621 displayed on the right side of the menu item 620 is set as the grid setting of the moving image mode. Of the options (switching settings, grid settings) included in the shooting information display settings, in the display example, menu items 602 and 619 are surrounded by a selection cursor 608, and switching settings are selected for both the still image mode and the moving image mode. It is shown that.

  FIG. 6C shows a display example of the grid setting screen in the still image mode, and FIG. 6D shows a display example of the grid setting screen in the moving image mode. In both the still image mode and the moving image mode, the operation to display the grid setting screen and the menu name to be displayed are the same, but items (selectable items) displayed on the grid setting screen are different. In addition, grid settings (setting of auxiliary shooting lines) being set in the still image mode and the moving image mode are stored in the nonvolatile memory 56, respectively. As shown in FIG. 6C, in the still image mode, the user can select a grid line from among items 606 indicating the grid 1 and items 607 indicating the grid 2. By displaying the grid lines in still image shooting, the user can easily confirm the composition and the horizontal state. The grid 1 is a grid line that allows the display area to be divided into 3 × 3 areas, and the grid 2 is a grid line that allows the display area to be divided into 6 × 4 areas. As shown in FIG. 6D, in the moving image mode, in addition to grid 1 (item 610) and grid 2 (item 611) that can be set in the still image mode, an auxiliary shooting line is selected from five aspect ratios. Can do. In the moving image mode, the aspect ratio is 2.35: 1 (item 612), the aspect ratio is 1.85: 1 (item 613), the aspect ratio is 1.75: 1 (item 614), and the aspect ratio is 1.66: 1 (item 615). ), An aspect marker with an aspect ratio of 4: 3 can also be selected. The aspect ratio 4: 3 is not shown because scrolling is necessary. In moving image shooting, by displaying an aspect marker indicating the aspect ratio used in editing, the user can proceed with the creation of a moving image while considering editing of the moving image being shot. By displaying an aspect marker suitable for the format used by the user during shooting of a moving image, the user can easily perform editing work and can perform shooting while taking into account editing. In the moving image mode, the grid 1 and the grid 2 that can be set in the still image mode can also be selected as photographing auxiliary lines. For users who do not need editing work in the moving image mode or for users who place more importance on grid lines, it is easier to perform shooting if the grid lines are displayed.

  A display flow of the photographing auxiliary line will be described with reference to FIG. This process is realized by developing a program recorded in the nonvolatile memory 56 in the system memory 52 and executing it by the system control unit 50. The process of FIG. 3 starts when the digital camera 100 is turned on and can be displayed on the display unit 28.

  In S301, the system control unit 50 determines whether the currently set mode is the shooting mode. If it is determined that the shooting mode is set, the process proceeds to S304, and if not, the process proceeds to S302. Here, it is determined whether or not the shooting mode is set among a shooting mode for shooting (still image mode, moving image mode), a playback mode for confirming a shot image, a setting mode for setting the digital camera 100, and the like. judge.

  In S302, the system control unit 50 determines whether or not a mode switching operation has been performed. If it is determined that the mode switching operation has been performed, the process returns to S301, and if not, the process proceeds to S303. The mode switching operation can be performed by operating the mode switching switch 60 or a shooting mode setting operation on the menu screen.

  In step S303, the system control unit 50 proceeds to processing in another mode that is not the shooting mode. Here, processing in other modes is omitted. If the shooting mode is selected in another mode, the process returns to S301.

  In S304, the system control unit 50 determines whether or not the shooting mode being set is a mode included in the still image mode. If it is determined that the mode is included in the still image mode, the process proceeds to S305, and if not, the process proceeds to S322. That is, in S304, if the shooting mode set on the mode switch 60 or the menu screen is a shooting mode such as auto mode, sports, portrait, auto shutter, starry sky, simple night view, monochrome, etc., the mode included in the still image mode It is determined that On the other hand, if the shooting mode is a normal moving image, a short moving image, a manual exposure moving image, or the like, it is determined that a mode included in the moving image mode has been selected, and the process proceeds to S322. The shooting mode of the present embodiment includes a still image mode for mainly shooting still images and a moving image mode for mainly shooting moving images. Whether the mode is the still image mode or the moving image mode can be performed by an operation on the mode switch 60 or a shooting mode setting operation on the menu screen. Even if the shooting mode is changed, the shooting auxiliary line is not changed when both the shooting mode before the change and the shooting mode after the change are included in the still image mode (or the moving image mode). As described above, the auxiliary shooting line to be displayed is changed depending on whether the set shooting mode is included in the still image mode or the moving image mode.

  In S305, the system control unit 50 displays the live view image on the display unit 28 with the still image aspect ratio. FIG. 4A shows a display example of the live view image 402 on the display unit 28 in the still image mode. The aspect ratio of the still image is 4: 3 in this example. In the present embodiment, the aspect ratio of the displayable area of the display unit 28 is 4: 3. The display area 401 in still image shooting is the same as the displayable area of the display unit 28 and has an aspect ratio of 4: 3. The live view image 402 is taken as a white surface for simplification. The aspect ratio of the still image can be set to other than 4: 3 by user setting. When the aspect ratio of the still image is set to a different aspect ratio from that of the display area 401, an aspect in which a non-image area such as a pillar box or letter box is attached and the live view image is set as the aspect ratio of the still image. Display as a ratio.

  In S <b> 306, the system control unit 50 displays the shooting auxiliary line for the still image mode being set based on the setting stored in the nonvolatile memory 56 on the display unit 28 as a live view image (in this example, a live view image). The image 402) is superimposed and displayed. FIG. 4A shows a display example of the display unit 28 when a 3 × 3 grid line is set in the grid setting. At this time, four grid lines 403 are drawn so that the lengths of the vertical and horizontal sides of the live view image 402 are each divided into three, and the live view image 402 is divided into nine.

  In step S307, the system control unit 50 determines whether a shooting mode switching operation has been performed. If it is determined that the shooting mode switching operation has been performed, the process returns to S304, and if not, the process proceeds to S308.

  In S308, the system control unit 50 determines whether the menu button 74 has been pressed. If it is determined that the menu button 74 has been pressed, the process proceeds to S309, and if not, the process proceeds to S311.

  In step S309, the system control unit 50 performs shooting menu setting. The menu setting during shooting is a setting of items related to shooting set during the shooting mode, and includes items different from items that can be set by pressing the menu button 74 during the playback mode or the setting mode. In shooting menu settings, settings such as shooting information display settings (including display settings for auxiliary shooting lines), zoom settings, camera shake correction, and the like that need to be set during shooting can be performed. Details of the menu setting process during shooting will be described later with reference to FIG.

  In S310, the system control unit 50 displays the shooting assistance line for the still image mode superimposed on the live view image, reflecting the setting change in S309. When the setting of the auxiliary shooting line is not changed in S310, the display of the auxiliary shooting line (the grid line 403 in the example of FIG. 4A) does not change from S306.

  In step S311, the system control unit 50 determines whether a moving image shooting start instruction has been issued. An instruction to start moving image shooting can be issued by pressing the moving image button 63. Alternatively, the moving image shooting may be started by performing a touch operation on the moving image start button displayed on the display unit 28 (not shown).

  In S312, the system control unit 50 starts moving image shooting.

  In step S313, the system control unit 50 displays an image being shot with a moving image aspect ratio. As shown in FIG. 4B, the image 404 being captured is displayed on the display unit 28 in the display area 401. In this example, the aspect ratio of the moving image is set to an aspect ratio 16: 9 different from that of the display area 401. Therefore, the non-image area as described in S305 is added, and the live view image 404 is set as the aspect ratio of the moving image. Display with the specified aspect ratio. FIG. 4B shows a display example of the display unit 28 during shooting when moving image shooting is performed in the still image mode. By displaying the live view image 404 in this way, the user can recognize that the area recorded as a moving image is 16: 9.

  In S <b> 314, the system control unit 50 causes the display unit 28 to display the shooting auxiliary line for the still image mode that is being set so as to be superimposed on the image being shot. FIG. 4B shows a display example of a shooting auxiliary line for the still image mode during moving image shooting. FIG. 4B is a display example when the grid 1 is set as a photographing auxiliary line for the still image mode, and is superimposed on the live view image 404 of the 16: 9 moving image, and a 3 × 3 grid line is displayed. 405 is displayed. In FIG. 4A, the still image mode shooting auxiliary line (in this example, the grid line 403) is displayed in the still image aspect ratio display area 401, but in S314, it is adjusted to the 16: 9 moving image aspect ratio. To display. Therefore, the grid line display interval (distance between lines in the vertical direction in the example of FIG. 4) is different from that for a still image.

  In step S315, the system control unit 50 determines whether an instruction to end moving image shooting has been issued. If it is determined that an instruction to end moving image shooting has been given, the process proceeds to S316; otherwise, the process waits until an instruction to end moving image shooting is issued. Here, the moving image shooting end instruction can be performed by pressing the moving image button 63. Alternatively, the moving image shooting may be ended by performing a touch operation on the moving image end button displayed on the display unit 28 (not shown). Alternatively, the moving image shooting ends even when the power is turned off or the battery is exhausted. In such a case, the digital camera 100 itself is turned off without proceeding to S316.

  In S316, the system control unit 50 performs a photographing end process. The shooting end process is a process for reproducing the created moving image by performing moving image attribute information, inter-frame information, thumbnail creation, compression processing, and the like. Such information is stored in the recording medium 200 together with the moving image.

  In S317, the system control unit 50 determines whether or not the first shutter switch signal SW1 is turned on by half-pressing the shutter button 61. If it is determined that SW1 is turned on, the process proceeds to S318, and if not, the process proceeds to S321.

  In S318, the system control unit 50 prepares for shooting. Shooting preparation refers to operations such as AF processing, AE processing, AWB processing, and EF processing.

  In S319, the system control unit 50 determines whether or not the second shutter switch signal SW2 is turned on by fully pressing the shutter button 61. If SW2 is turned on, the process proceeds to S320, and if not, the process proceeds to S321.

  In S320, the system control unit 50 performs still image shooting end processing. Here, an image (still image) obtained by the imaging unit 22 is recorded on the recording medium 200.

  In S321, the system control unit 50 determines whether an end operation has been performed. If it is determined that the ending operation has been performed, the power is turned off. If not, the process returns to S307. Here, the ending operation is an operation for turning off the power. Or when the battery runs out, the power turns off.

  On the other hand, in S322, the system control unit 50 displays the live view image with the aspect ratio of the moving image. As shown in FIG. 4C, in the present embodiment, in the moving image mode, the display area 401 (4: 3 aspect ratio) has a different size and a different aspect ratio (16 in this example). : 9), the live view image 408 is displayed. FIG. 4C shows a display example of a shooting auxiliary line for the moving image mode during shooting standby in the moving image mode. FIG. 4C is an example of an aspect marker display when an aspect ratio of 4: 3 is set as a shooting assistance line for the moving image mode. The aspect marker is superimposed on the live view image 408 of 16: 9, and 3 aspect markers 409 are displayed.

  In step S323, the system control unit 50 causes the display unit 28 to display the shooting auxiliary line for the moving image mode being set in a superimposed manner on the image 404 being shot based on the setting information stored in the nonvolatile memory 56.

  S324 to S326 are the same processes as S307 to S309.

  In S327, the system control unit 50 reflects the setting change in S326 and superimposes the shooting auxiliary line for the moving image mode being set on the image being shot. If the setting of the auxiliary shooting line is not changed in S326, the display of the auxiliary shooting line is not changed from S323.

  S328 to S329 are the same processes as S311 to S312.

  In S330, similarly to S323, the system control unit 50 causes the display unit 28 to display the shooting auxiliary line for the moving image mode being set so as to be superimposed on the image being shot (the image 410 in the present embodiment). If the setting of the auxiliary shooting line has not been changed in S326, the display of the auxiliary shooting line (the aspect marker 409 in the example of FIG. 4C) does not change from S323. In addition, a REC display indicating that a moving image is being captured, an elapsed shooting time, or the like may be displayed. In S314, the grid line 405 (shooting auxiliary line set in the still image mode) is displayed during moving image shooting. In S330, shooting set in the moving image mode such as the aspect marker 409 during moving image shooting. Display auxiliary lines. In S330, the shooting assistance line is displayed superimposed on the image being shot, but the shooting assistance line to be displayed is the same display as in S327.

  S331 to S337 are the same processes as S315 to S321.

  Next, the flow of menu setting during shooting will be described with reference to FIG. The process of FIG. 5 is a detail of the process when the process proceeds to step S309 or S326 in FIG. 3 and the menu name of the shooting information display setting is selected in the shooting menu setting. The case where the menu name for setting zoom setting, camera shake correction, etc. is selected is omitted here. This process is realized by developing a program recorded in the nonvolatile memory 56 in the system memory 52 and executing it by the system control unit 50.

  In S501, the system control unit 50 determines whether or not the current shooting mode is a mode included in the still image mode. If it is determined that the mode is included in the still image mode, the process proceeds to S502, and if not, the process proceeds to S510. That is, in S501, if the shooting mode set on the mode switch 60 or the menu screen is an auto mode, sport, portrait, auto shutter, starry sky, simple night view, monochrome, etc., the mode is included in the still image mode. judge. On the other hand, if the shooting mode is a normal moving image, a short moving image, a manual exposure moving image, or the like, it is determined that the mode included in the moving image mode has been selected, and the process proceeds to S510.

  In S <b> 502, the system control unit 50 displays menu items for the still image mode on the display unit 28. FIG. 6A is a display example of a shooting information display setting screen displayed when a menu screen is displayed in the still image mode and shooting information display setting which is one of the menu items is selected. .

  In step S503, the system control unit 50 determines whether the menu item 603 indicated by the grid setting (shooting auxiliary line setting) on the shooting information display setting screen is selected. If it is determined that the grid setting has been selected, the process proceeds to S504, and if not, the process proceeds to S522.

  In step S <b> 504, the system control unit 50 displays the above-described still image mode grid setting screen (FIG. 6C) on the display unit 28.

  The item being set (item 606 in FIG. 6C) is surrounded by the selection cursor 604.

  In step S505, the system control unit 50 determines whether an item moving operation has been performed. If it is determined that there has been a moving operation, the process proceeds to S506, and if not, the process proceeds to S508. The item moving operation can be performed by pressing the upper key 65 a or the lower key 65 b of the cross key 65 or rotating the controller wheel 73.

  In step S506, the system control unit 50 determines whether the item 606 indicating the grid 1 is selected. If it is determined that the item 606 has been selected, the process proceeds to S508, and if not, the process proceeds to S507.

  In S507, the system control unit 50 determines whether or not the item 607 indicating the grid 2 is selected. If it is determined that the item 607 has been selected, the process proceeds to S508, and if not, the process returns to S505. In FIG. 6C, the selection cursor 604 moves to the item 607 in response to the move operation performed on the item 607.

  In step S <b> 508, the system control unit 50 determines whether the item indicating the selected photographing auxiliary line has been determined. If it is determined that it has been determined, the process proceeds to S509, and if not, the process returns to S505. The photographing auxiliary line is set to the selected photographing auxiliary line (item) in response to pressing of the SET button 66. In FIG. 6C, when the SET button 66 is pressed, the grid 1 is set. By displaying the SET display 616, it is understood that the item being selected is set by pressing the SET button 66.

  In step S <b> 509, the system control unit 50 sets the selected shooting auxiliary line item as a shooting auxiliary line in the still image mode and records it in the nonvolatile memory 56.

  In S <b> 510, the system control unit 50 displays the moving image mode menu items on the display unit 28. FIG. 6B is a display example of a shooting information display setting screen displayed when the menu screen is displayed in the moving image mode and the shooting information display setting which is one of the menu items is selected.

  On the other hand, in S511, the system control unit 50 determines whether or not the menu item 620 indicated by the grid setting (shooting auxiliary line setting) on the shooting information display setting screen is selected. If it is determined that the grid setting has been selected, the process proceeds to S512, and if not, the process proceeds to S522.

  In S <b> 512, the system control unit 50 displays the above-described moving image mode grid setting screen (FIG. 6D) on the display unit 28. In S512, a selection display indicating that the item being set is selected is displayed. The item being set (item 614 in FIG. 6D) is surrounded by the selection cursor 604.

  In step S513, the system control unit 50 determines whether an item moving operation has been performed. If it is determined that there has been a moving operation, the process proceeds to S514; otherwise, the process proceeds to S520. The item moving operation can be performed by pressing the upper key 65 a or the lower key 65 b of the cross key 65 or rotating the controller wheel 73.

  In S514 to S519, the system control unit 50 determines whether any of the items shown in FIG. 6C has been selected. The selection candidate items include the same grid 1 (item 610) and grid 2 (item 611) as in the still image mode, and the following items. Aspect ratio 2.35: 1 (item 612), aspect ratio 1.85: 1 (item 613), aspect ratio 1.75: 1 (item 614), aspect ratio 1.66: 1 (item 615), aspect ratio 4: 3 (not shown) is a further selection candidate item. If the item is not selected in S514 to S519, the aspect ratio 4: 3 is selected, and the process proceeds to S520.

  In step S520, the system control unit 50 determines whether or not the item (grid line or aspect marker item) indicating the selected photographing auxiliary line has been determined. If it is determined that it has been determined, the process proceeds to S521, and if not, the process returns to S513. In response to the pressing of the SET button 66, the selected shooting auxiliary line (item) is set. In FIG. 6D, when the SET button 66 is pressed, the aspect ratio is set to 1.75: 1.

  In S521, the system control unit 50 sets the selected shooting auxiliary line item (aspect marker or grid line) as a shooting auxiliary line in the moving image mode, and separately from the setting information of the shooting auxiliary line for the still image mode, Record in the nonvolatile memory 56. In this way, in the movie mode, it is possible to set the shooting auxiliary line from the aspect marker and grid line, but since each is another option (selectable setting item) within the same menu item, both the aspect marker and grid line are At the same time, they are not displayed on the display unit 28.

  On the other hand, in S522, the system control unit 50 determines whether or not another item being shot is selected. If it is determined that it has been selected, the process proceeds to S523, and if not, the process proceeds to S524.

  In S523, the system control unit 50 performs setting for the item selected in S522. I won't go into details here.

  In S524, the system control unit 50 determines whether or not an end operation has been performed. If it is determined that the end operation has been performed, the menu setting during shooting is ended, and if not, the process proceeds to S502. The end operation is pressing of the menu button 74. When the menu setting during shooting is completed, the process proceeds to S310 or S327 in FIG.

  As described above, according to the embodiment described above, in the still image mode and the moving image mode, it is possible to display the auxiliary shooting line corresponding to each mode in accordance with the switching to each mode. Further, the user can set an auxiliary shooting line in each of the still image mode and the moving image mode. In still image shooting, displaying the grid lines set in the still image mode makes it easier for the user to check the composition and the horizontal state with the grid lines to be checked during still image shooting. In movie shooting, the grid line or aspect marker set in the movie mode is displayed as an auxiliary shooting line so that the user can shoot a movie using the grid line or aspect marker that he / she wants to check when shooting the movie. Can do. In addition, the shooting auxiliary line in the still image mode is set during shooting in the still image mode, and the shooting auxiliary line is set in the moving image mode during shooting in the video mode. It can be carried out. Since only items suitable for the still image mode are displayed as options during shooting in the still image mode, and only items suitable for the movie mode are displayed as options during shooting in the moving image mode, the selection operation can be performed more intuitively. Although the shooting auxiliary line for the still image mode and the shooting auxiliary line for the movie mode can be set separately, there is no item in the menu, so the user does not have to be aware that they must be set separately. , You can avoid feeling bothered. Further, if the shooting assistance setting is performed in each shooting mode, a setting screen corresponding to each shooting mode is displayed, so that it is possible to reduce the possibility of confusing items and setting contents set by the user.

  In the still image mode, only the grid lines set as the photographing auxiliary display in the still image mode and in the moving image mode, only the grid lines or the aspect markers set as the photographing auxiliary display in the moving image mode are displayed. Also, both grid lines and aspect markers are not displayed at the same time. Since the display unnecessary for the user is not superimposed on the live view image or the image being captured, the visibility of the captured image does not deteriorate. Furthermore, the user does not know what the display means, and the possibility of shooting with an incorrect angle or size is reduced.

  In this embodiment, regardless of the mode (whether in the still image mode or the moving image mode), it is possible to shoot a still image by fully pressing the shutter button 61, and to shoot a moving image by pressing the moving image button 63. Is possible. That is, the auxiliary shooting line suitable for the shooting mode is set depending on whether the currently set shooting mode is a mode for shooting still images or a mode for shooting moving images. In addition, when moving image shooting is started in the still image mode, the display area displays the grid lines set in the still image mode while changing the aspect ratio for the moving image. Therefore, when shooting a moving image in the still image mode, it is possible to perform shooting while observing a desired composition according to the size of the image on which the moving image is recorded (while watching the set grid line). .

  The shooting assistance setting can also be performed in the operation on the touch panel 70a. In addition, since the user can select and set items more intuitively using the touch panel 70a, the position for drawing the grid line may be set by a touch operation. That is, by determining the position of the grid line on the display unit 28 according to the touch position on the touch panel 70a, the user can perform shooting with the grid line corresponding to each shooting.

  Note that the setting values of the grid lines and aspect markers shown in this embodiment are merely examples, and the present invention is not limited to these. The grid line and aspect marker may be set by the user instead of selecting from several candidates. In the still image mode, an item other than the grid line may be selectable as the selectable item of the shooting assistance line. Further, not only grid lines and aspect markers but also other types of auxiliary shooting lines may be selected. For example, a level or an AF frame may be used as a candidate.

  The modes included in the still image mode and the moving image mode are not limited to the modes described in the present embodiment. In a mode that is not included in either the still image mode or the moving image mode, or a mode in which shooting of a still image or a moving image is switched according to a shooting instruction, the shooting mode may not be divided as in the present embodiment. If the shooting mode is not fixed before shooting, the display may be changed according to the type of shooting performed in the last set mode. That is, a grid line set by the user may be displayed in response to the still image shooting, and an aspect marker or grid line set by the user may be displayed in response to the moving image shooting. . In this way, when either the still image shooting or the moving image shooting is performed, when the shooting auxiliary line is changed to a display corresponding to each shooting mode, the user does not need to perform an operation of switching the display. It is possible to shoot with the shooting auxiliary line.

  In the present embodiment, the display of either the grid line or the aspect marker has been described, but the auxiliary shooting line may not be necessarily provided.
