Indicates that it is set. In addition to this, on the menu screen, an icon indicating the shutter speed, the aperture value, the exposure correction value, and the current remaining state of the battery 32 (in the example of FIG. An icon 51) and an icon indicating the set shooting scene mode (icon 52 in the example in the figure) are also displayed. In the menu screen, the highlighted portion (in the example shown in the figure, “flash emission prohibited”) indicates the portion selected on the screen. In the present embodiment, such highlighting is handled as a cursor for processing. Therefore, in the following description, the movement of the cursor refers to the movement of the highlighted portion, and the cursor position refers to the highlighted portion. However, the present invention is not limited to such highlighting, and it is also possible to perform processing by treating other means as a cursor, such as by providing a frame.

  When a switch input (button operation) is detected while such a menu screen is displayed (S11 in FIG. 5), it is determined which switch the switch input is from (S12).

If the determination result in S12 is the switch of the cancel button 42, menu cancel processing is performed (S13), and the process returns to S5 to return to the shooting standby state.
When the determination result of S12 is the switch of the upper button 44a or the lower button 44c of the cross button 44, the cursor (the position of the highlighted portion) is moved according to the switch (S14), and the process returns to S10. For example, when the switch is the down button 44c, the cursor is moved downward.

  FIG. 9 is a diagram illustrating an example of the menu screen after the cursor has moved. The screen example shown in the figure is a menu screen displayed after the down button 44c is pressed twice from the state of the menu screen shown in FIG. The position of the cursor has been changed from “flash emission prohibited” to “image quality 2592 × 1920 1/8”. In the menu screen according to the present embodiment, the setting items are displayed every four items. When the mark 56 is displayed, the down button 44c is pressed when the cursor is on the setting item at the bottom. By pressing the button, the following four setting items can be displayed. Further, when a similar mark (not shown) is displayed in the upper part of the uppermost setting item, when the cursor is on the uppermost setting item, the upper four items 44 are depressed to depress the previous four items.

In FIG. 5, when the determination result of S12 is the switch of the OK button 45, the setting item of the cursor position is determined (S15).
When the determination result in S15 is other than “image quality” (for example, when the OK button 45 is pressed on the menu screen shown in FIG. 8), menu processing corresponding to the setting item of the cursor position is performed (S16). Return to S10.

  When the determination result of S15 is “image quality” (for example, when the OK button 45 is pressed on the menu screen shown in FIG. 9), the process proceeds to the processing for displaying the image quality setting screen shown in FIG. To do.

If the determination result of S7 is a switch of another button, processing corresponding to the switch is performed (S17), and the process returns to S5.
FIG. 6 is a flowchart showing a process for displaying an image quality setting screen, which is performed when the determination result in S15 is “image quality”.

  As shown in the figure, in this process, first, the set vertical axis item is selected from the vertical axis item table shown in FIG. 2 (a) (S21), and the contents of the selected vertical axis item are shown in FIG. Obtained from any of the data tables shown in 3 (a) to (f) (S22). For example, if the set vertical axis item remains the initial setting in S4, the vertical axis item “number of pixels” is selected from the vertical axis item table, and the data table shown in FIG. To get its contents.

  Subsequently, the set horizontal axis items are selected from the horizontal axis item table shown in FIG. 2 (b) (S23), and the contents of the selected horizontal axis items are shown in FIGS. 3 (a) to 3 (f). Obtained from one of the data tables (S24). For example, if the set horizontal axis item is the initial setting in S4, the horizontal axis item “compression rate” is selected from the horizontal axis item table, and the data table shown in FIG. To get its contents.

  Subsequently, the set content item is selected from the content item table shown in FIG. 2 (c) (S25), and it is further specified whether the information of the content item is obtained by calculation or by referring to the data table. It is determined which information of the selected content item is obtained from the data (S26). Then, according to the determination result of S26, the information of the selected content item is obtained by calculation from the combination of the content of the vertical axis item and the content of the horizontal axis item (S27), or FIG. 3 (a) and (b) ) By referring to the data table shown in FIG. For example, if the vertical axis item, horizontal axis item, and content item that have been set remain the initial settings in S4, the content item “number of shootable images” is selected, and the above equation (1) is obtained. Using the calculation, information on the content item “number of storable images” that matches each combination of the parameter included in the content of the vertical axis item “number of pixels” and the parameter included in the content of the horizontal axis item “compression rate” is acquired. To do.

  In this way, when the vertical axis item and its content, the horizontal axis item and its content, and the content item and its information are selected and acquired, the “image quality” setting screen (image quality) is displayed on the TFT liquid crystal display 21 based on them. The setting screen is displayed (S29).

  FIG. 10 is a diagram illustrating an example of the image quality setting screen. As shown in the figure, the image quality setting screen displays the vertical axis item and its content, the horizontal axis item and its content, and the content item and its information selected and acquired in S21 to S28. However, in this case, on the left side of the screen, the vertical axis items are arranged in order from the top along the vertical axis direction (vertical direction), and then the contents of the vertical axis items are arranged and displayed in the order of image quality. . In the lower part of the screen, the horizontal axis items are arranged in order from the left along the horizontal axis direction (left and right direction), and then the contents of the horizontal axis items are arranged and displayed in the order of image quality. Furthermore, the content item information that matches each combination of the parameter of the vertical axis item and the parameter of the horizontal axis item is arranged in a matrix in ascending or descending order, and the content item is arranged above the information. Is displayed.

  The screen example shown in the figure is an image quality setting screen displayed when the vertical axis item, horizontal axis item, and content item that have been set are the initial settings in S4. Accordingly, in the left part of the screen, the vertical axis item “number of pixels” is arranged in order from the top along the vertical axis direction, and then the contents of the vertical axis item are “2592 × 1920” and “1280 × 960”. , “640 × 480” are arranged and displayed in the order of image quality. Further, in the lower part of the screen, the horizontal axis item “compression rate” is arranged in order from the left along the horizontal axis direction, and then the contents of the horizontal axis item are “1 / 2.7” and “1”. / 8 "and" 1/12 "in order of image quality. In addition, information on the content items that match each combination of the parameters of the vertical axis item and the horizontal axis item that are arranged is sequentially arranged in a matrix, and the content item “number of shootable images” is arranged above the information. Displayed. With such a display, the user can confirm the relationship among the “number of pixels”, “compression ratio”, and “number of shootable images”, and the “pixel number” while considering the “number of shootable images” as the image quality setting. Number and compression rate can be set.

  In addition, in the information of the content item displayed on the image quality setting screen, partial information that matches the currently set combination of the vertical axis parameter and the horizontal axis parameter, or on the screen according to S33 described later. The partial information selected in is highlighted so that it can be distinguished from others. In the present embodiment, as described above, such highlighting is handled as a cursor for processing. A mark indicating the direction in which the cursor can be moved is also displayed around the partial information at the cursor position.

  The screen example shown in the figure is also an image quality setting screen displayed immediately after the OK button 45 is pressed on the menu screen in the state shown in FIG. Accordingly, as the current setting of “image quality”, “number of pixels” is set to “2592 × 1920” and “compression rate” is set to “1/8”. The position “10” becomes the cursor position. In addition, around the partial information “10” at the cursor position, marks 57, 58, and 59 indicating the cursor movable direction (left direction, downward direction, right direction) are displayed.

  In addition to this, the image quality setting screen also has an icon indicating the shutter speed, the aperture value, the exposure correction value, and the current state of the remaining battery 32 (example of FIG. Then, an icon 51) and an icon indicating the set shooting scene mode (icon 52 in the example in the figure) are also displayed.

  When a switch input (button operation) is detected while such an image quality setting screen is displayed (S30 in FIG. 6), it is determined which switch the switch input is from (S31).

If the determination result in S31 is the switch of the cancel button 42, menu cancel processing is performed (S32), and the process returns to S5 in FIG. 5 to return to the shooting standby state.
If the determination result of S31 is a switch of the cross button 44 (up button 44a, right button 44b, down button 44c, or left button 44d), a cursor (position of partial information to be highlighted) is displayed according to the switch. Move (S33) and return to S29. For example, when the left button 44d is pressed on the image quality setting screen shown in FIG. 10, the cursor moves to the position of the partial information “5”.

  When the determination result of S31 is the switch of the switching button 41, the set content item is changed to another content item (S34). The content items are changed in the order of items described in the content item table shown in FIG. 2 (c), that is, “number of shootable images” → “continuous shooting speed” → “shooting interval” → “file size”. → “Number of pixels & compression rate” → “Number of storable pictures”. Therefore, for example, when the change button 41 is pressed when the currently set content item is “number of shootable images”, the content item is changed to the next item “continuous shooting speed”.

  When the set content item is changed in this way, the process returns to S25, and the changed content item is selected from the content item table in the same manner as described above, and the information of the content item is calculated or stored in the data table. Obtained by reference, the image quality setting screen is displayed again. As a result, the content item and its information displayed on the image quality setting screen are changed. Note that the cursor position in the content item information after the change matches the combination of the parameter of the vertical axis item and the parameter of the horizontal axis item corresponding to the partial information of the cursor position in the content item information before the change. It becomes the position of the partial information in the information of the content item.

  FIG. 11 is an example of the image quality setting screen displayed after the switch button 41 is pressed when the image quality setting screen shown in FIG. 10 is displayed. In this case, since the set content item is changed from “shootable number” to “continuous shooting speed”, “continuous shooting speed” is displayed as the content item as shown in FIG. As information, information on “continuous shooting speed” suitable for each combination of the parameter “number of pixels” and the parameter “compression ratio” is arranged and displayed in order in a matrix. Further, since the cursor position on the image quality setting screen shown in FIG. 10 is the position of the partial information “10”, the “pixel count” corresponding to the partial information “10” is displayed on the image quality setting screen shown in FIG. The position of the partial information “2.2” of “continuous shooting speed” that matches the combination of “2592 × 1920” and “compression ratio” “1/8” becomes the cursor position. Such a display allows the user to set “number of pixels” and “compression ratio” while considering “continuous shooting speed” instead of “number of shootable images” as a setting for image quality. You can set the image quality.

  FIG. 12 is an example of an image quality setting screen displayed after the switch button 41 is pressed when the image quality setting screen shown in FIG. 11 is displayed. In this case, since the set content item is changed from “continuous shooting speed” to “shooting interval”, “shooting interval” is displayed as the content item as shown in FIG. The information of “shooting interval” that matches each combination of the “number of pixels” parameter and the “compression ratio” parameter is sequentially arranged and displayed in a matrix. Further, since the cursor position on the image quality setting screen shown in FIG. 11 is the position of the partial information “2.2”, the image quality setting screen shown in FIG. 12 corresponds to the partial information “2.2”. The position of the partial information “9.6” of “shooting interval” that matches the combination of “number of pixels” “2592 × 1920” and “compression rate” “1/8” becomes the cursor position. Such a display allows the user to set the “number of pixels” and “compression ratio” while taking into consideration the “shooting interval” instead of the “shootable number” and “continuous shooting speed” as the image quality setting. Thus, the image quality can be set from another viewpoint.

Thereafter, when the switching button 41 is further pressed and the content item is changed to “file size” or “pixel number & compression rate”, the same processing is performed.
In FIG. 6, when the determination result in S31 is the switch of the OK button 45, the vertical axis parameter and horizontal axis parameter corresponding to the partial information at the current cursor position are set as the image quality settings. (S35). For example, when the OK button 45 is pressed on the image quality setting screen shown in FIG. 10, the partial information at the cursor position is “10”. The “number of pixels” is set to “2592 × 1920” and the “compression rate” is set to “1/8”. The same is true when the OK button 45 is pressed on the image quality setting screen shown in FIGS.

  When the image quality setting is completed in this way, display update processing is performed to update the display of the shooting standby screen in accordance with the partial information of the cursor position when the OK button 45 is pressed (S36), and the process proceeds to S5 in FIG. Return to the shooting standby state. As a result, the imaging standby screen after the display update process is displayed on the TFT liquid crystal display 21.

  13 and 14 are diagrams illustrating an example of the shooting standby screen after the display update process. FIG. 13 illustrates a screen example when the OK button 45 is pressed in the image quality setting screen illustrated in FIG. Is a screen example when the OK button 45 is pressed on the image quality setting screen shown in FIG.

  As shown in both figures, in the shooting standby screen after the display update process, the partial information is additionally displayed according to the partial information at the cursor position when the OK button 45 is pressed, and the number of pixels is also displayed. The set value and the remaining number of shootable images in the current setting are updated. However, the content item partial information originally displayed on the shooting standby screen (for example, the partial information of the content item “number of shootable images”) is not newly displayed additionally. The value set as the number of pixels and the remaining number of shootable images in the current setting are not updated unless there is a change.

  Since the screen example shown in FIG. 13 is a screen example when the OK button 45 is pressed on the image quality setting screen shown in FIG. 11, the partial information “2.2” at the cursor position is additionally displayed. However, since the partial information “2.2” is partial information of the content item “continuous shooting speed”, “2.2 fps” is displayed together with the unit “fps” (frame per second). Thereby, the user can also confirm the partial information “2.2” of the content item “continuous shooting speed” selected by the user on the image quality setting screen on the shooting standby screen. Since the number of pixels and the compression rate that have been set are not changed, the value set as the number of pixels (“2592 × 1920”) and the remaining number of shootable images (“ There is no change in the value of “10”).

  Since the screen example shown in FIG. 14 is a screen example when the OK button 45 is pressed on the image quality setting screen shown in FIG. 12, the partial information “9.6” at the cursor position is additionally displayed. However, since the partial information “9.6” is partial information of the content item “shooting interval”, “9.6 sec” is displayed together with the unit “sec”. As a result, the user can also confirm the partial information “9.6” of the content item “shooting interval” selected by the user on the image quality setting screen on the shooting standby screen. Since the number of pixels and the compression rate that have been set are not changed, the value set as the number of pixels (“2592 × 1920”) and the remaining number of shootable images (“ There is no change in the value of “10”).

  As described above, according to the digital camera which is the imaging apparatus according to the present embodiment, when setting the number of pixels and the compression rate as the image quality setting, the user can select “number of shootable images”, “continuous shooting speed”, “shooting interval”. ”,“ File size ”, and“ number of pixels & compression rate ”, by selecting the desired content item, the selected content item that matches each combination of the pixel number parameter and the compression rate parameter Information can be displayed. Therefore, the user can set the number of pixels and the compression rate in consideration of the information of the content item. In addition, since the content items to be preferentially taken into consideration can be freely changed, the user can easily perform image quality setting in accordance with his / her own shooting intention according to the situation.

  In addition, the shooting standby screen displays the set shutter speed, aperture value, exposure compensation value, shooting scene mode, etc., as well as the partial information of the content item selected by the user. Can be confirmed on the same screen at a time.

Note that the digital camera according to the present embodiment can be configured such that the vertical axis item and the horizontal axis item can be changed by combining the configuration and operation of the digital camera according to the second embodiment described later.
<Second Embodiment>
The digital camera which is the imaging device according to the second embodiment of the present invention is different from the digital camera according to the first embodiment in that the switching button is omitted, and the content item is changed by other means instead.

  Specifically, in FIG. 16 and FIG. 17, the processing of S41 to 53 is the same as the processing of S21 to 33 shown in FIG. Also, the processing of S54 and S55 performed when the determination result of S51 of FIG. 16 is the switch of the OK button 45 is the same as the processing of S35 and 36 shown in FIG.

  On the other hand, if the determination result in S51 of FIG. 16 is the switch of the menu button 43, the process proceeds to the flow shown in FIG. 17, and first, an item setting screen is displayed on the TFT liquid crystal display 21 (S61). On the item setting screen, the vertical axis item, horizontal axis item, and content item can be changed.

  FIG. 18 is a diagram illustrating an example of the item setting screen. As shown in the figure, the item setting screen displays a vertical axis item, a horizontal axis item, and a content item that are currently set or changed in S66 described later. In the example screen shown in the figure, “pixel number”, “compression rate”, and “photographable number” are displayed as the vertical axis item, horizontal axis item, and content item. In addition to this, the item setting screen also shows the shutter speed, aperture value, exposure correction value, and current remaining battery level state displayed on the shooting standby screen (see, for example, FIG. 7). An icon (icon 51 in the example in the figure) and an icon indicating the set shooting scene mode (icon 52 in the example in the figure) are also displayed. In the item setting screen, the highlighted portion (in the example of FIG. 18, “vertical number” of the vertical axis item) indicates a portion selected on the screen. In this embodiment as well, it is assumed that processing is performed by treating such highlighting as a cursor. In addition, on the item setting screen, a mark (for example, marks 61 and 62 in the figure) indicating that the setting can be changed by pressing the upper button 44a or the lower button 44c is displayed above and below the cursor position portion. Further, a mark (for example, mark 63 in the figure) indicating that the cursor position can be moved by pressing the right button 44b or the left button 44d is displayed on the left, right, or left and right of the cursor position portion.

If the determination result of S63 is the switch of the upper button 44a or the lower button 44c of the cross button 44, the item displayed at the cursor position (highlighted portion) is changed to another item according to the switch. (S66), and the process returns to S61. The items are changed in the order of items described in the tables shown in FIGS. 2 (a), (b), and (c). Therefore, for example, when the down button 44c is pressed on the item setting screen shown in FIG. 18, the vertical axis item is “pixel” according to the item order described in the vertical axis item table shown in FIG. Number "is changed to" compression rate ".

  If the determination result in S63 is the switch of the right button 44b or the left button 44d of the cross button 44, the cursor (the position of the highlighted portion) is moved according to the switch (S67), and the process returns to S61. For example, when the right button 44b is pressed on the item setting screen shown in FIG. 18, the cursor moves to the “compression rate” position of the horizontal axis item.

  If the determination result of S63 is the switch of the OK button 45, it is determined whether the vertical axis item, horizontal axis item, and content item displayed on the current image quality setting screen are different (S81). If the determination result is Yes, these items are determined as setting items (S65), and the process returns to S41 to display the image quality setting screen again. On the other hand, if the determination result in S81 is No, a warning is displayed to indicate that any or all of the vertical axis item, horizontal axis item, and content item are the same (S82), and when a predetermined time has elapsed (S83). ), Return to S61.

FIG. 19 is a diagram illustrating an example of an image quality setting screen displayed after one or more of the vertical axis item, the horizontal axis item, and the content item are changed on the item setting screen as illustrated in FIG. .
In the example of the screen shown in FIG. 19, on the item setting screen, the vertical axis item is changed from “number of pixels” to “use”, and the horizontal axis item is changed from “compression rate” to “shooting interval”. Is an image quality setting screen that is displayed when the OK button 45 is pressed without changing the “number of shootable images”. According to this screen example, the user can set “use” and “shooting interval” as the image quality setting while taking into consideration the “number of shots”.

As described above, according to the digital camera that is the imaging apparatus according to the present embodiment, the vertical axis item, the horizontal axis item, and the content item displayed on the image quality setting screen include not only the content item but also the vertical axis item and the horizontal axis item. Therefore, the user can set the shooting image quality more in line with his / her own shooting intention.
