  FIG. 3 is a block diagram illustrating a circuit configuration of the electronic camera described above. The CPU 18 is constituted by a microcomputer or the like, inputs a signal output from each block of the camera body 200, performs a predetermined calculation, and outputs a control signal based on the calculation result to each block.

  The main switch 22 outputs an operation signal corresponding to the on operation or the off operation to the CPU 18. The CPU 18 starts power supply to each block from a power circuit (not shown) when receiving an ON operation signal, and stops power supply from the power circuit to each block when receiving an OFF operation signal.

  A timing generator (TG) 17 generates a timing signal in response to an instruction sent from the CPU 18 and supplies the timing signal to each of the driver 16, the analog signal processing circuit 11, and the A / D conversion circuit 12. The driver 16 accumulates charges in the image sensor 10, generates a drive signal for sweeping out the accumulated charges using the timing signal, and supplies the generated drive signal to the image sensor 10.

  The image sensor 10 is constituted by, for example, a CCD image sensor. The image sensor 10 captures a subject image formed on the imaging surface by the photographing lens 100. That is, signal charges corresponding to the brightness of the subject image are accumulated. Imaging is started, for example, when the CPU 18 that has received an ON signal of a full-press switch 29 described later sends an instruction to the timing generator (TG) 17.

  The analog signal processing circuit 11 includes an AGC circuit, a CDS circuit, and the like, and performs analog processing (gain control, noise removal, etc.) on the photoelectric conversion signal (accumulated charge) output from the image sensor 10. The A / D conversion circuit 12 converts the image pickup signal after analog processing into a digital signal.

  The half-press switch 28 and the release switch 29 are turned on / off in conjunction with a pressing operation of a release button (not shown), and each outputs an operation signal to the CPU 18.

  An image processing circuit 13 composed of an ASIC (Application Specific Integrated Circuit) or the like performs image processing. The image processing circuit 13 performs contour enhancement processing, γ conversion processing, white balance processing, and the like on the digitally converted image data. The JPEG compression / decompression circuit 14 performs a compression process for compressing image data in the JPEG format and a decompression process for decompressing the compressed image data.

  The SDRAM 19 is a working memory that temporarily stores data when the CPU 18, the image processing circuit (ASIC) 13, the JPEG compression / decompression circuit 14, and the like are processed. The memory 20 is a nonvolatile memory such as an EEPROM or a flash memory that stores an operation program, setting information, and the like of the camera body 200. The CPU 18 also generates display data for displaying a menu screen and a reproduced image on the liquid crystal monitor 21. The generated display data is temporarily stored in the SDRAM 19 and displayed on the liquid crystal monitor 21.

  The recording medium 27 is constituted by a data storage member such as a flash memory card, for example. The CPU 18 can store data such as a captured image on the recording medium 27 and can read data stored on the recording medium 27.

  Since the electronic camera of the present embodiment is characterized by the image quality adjustment setting for the captured image, the following description will focus on the image quality setting operation. FIG. 4 is a diagram for explaining a memory area for storing information relating to image quality adjustment.

(Normal image quality adjustment)
The electronic camera is configured to use a plurality of image quality adjustment algorithms. For example, the following four types of image quality adjustment algorithms are stored in the image quality adjustment information area provided in the memory 20.
[1] Standard [2] Neutral [3] Vivid [4] Monochrome

  “Standard” is an image quality adjustment algorithm for finishing a standard image. “Neutral” is an image quality adjustment algorithm that finishes with emphasis on the natural color of the material. “Vivid” is an image quality adjustment algorithm that finishes a vivid image. Specifically, the saturation is increased and red and green are processed vividly, and the contrast is increased to obtain a sharp image. “Monochrome” is an image quality adjustment algorithm for finishing a monochrome image. The image processing circuit 13 performs image quality adjustment processing on the captured image using the image quality adjustment algorithm set (selected) on the menu operation screen.

  Each image quality adjustment algorithm is configured to be able to change a plurality of parameter sets (hereinafter referred to as parameter groups) used in image quality adjustment processing. The parameter group includes, for example, a parameter for adjusting the strength of “contour emphasis”, a parameter for adjusting the strength of “contrast”, a parameter for adjusting “brightness”, and “saturation (darkness of color)”. Parameter) for adjusting “s)” and a parameter for adjusting “hue (hue)”.

When the parameter changing operation is not performed, the image processing circuit 13 performs image quality adjustment processing on the captured image using a parameter group (default value) set in advance for each image quality adjustment algorithm. For example, the following four types of standard parameter groups are stored in association with the corresponding image quality adjustment algorithm in the standard parameter area provided in the memory 20.
[1] SD default value [2] NL default value [3] VI default value [4] MC default value

  When the parameter changing operation is performed, the image processing circuit 13 performs image quality adjustment processing on the captured image using the changed parameter group. The changed parameter group is stored in the changed parameter area provided in the memory 20 in association with the corresponding image quality adjustment algorithm. In the example of FIG. 4, a parameter group (changed value) changed from the standard parameter group (VI default value) is stored in the changed parameter area.

(Addition of image quality adjustment algorithm)
The electronic camera is configured to be able to add an image quality adjustment algorithm. As an area for storing the image quality adjustment algorithm to be added, four reserved areas are secured in the image quality adjustment information area provided in the memory 20. When the image quality adjustment algorithm is added, the image quality adjustment algorithm is stored in the reserved area. The standard parameter group (default value) used in the image quality adjustment algorithm is stored in the standard parameter area provided in the memory 20 in association with the added image quality adjustment algorithm.

  When an image quality adjustment algorithm is added, the electronic camera can selectively use four types of image quality adjustment algorithms used for normal image quality adjustment and the added image quality adjustment algorithm. In addition, when using the added image quality adjustment algorithm, the standard parameter group (default value) is used when the parameter change operation is not performed, and the parameter after the change when the parameter change operation is performed The point of using groups is the same as in the case of the four image quality adjustment algorithms used in normal image quality adjustment.

(Save parameter group after change)
The electronic camera is configured to be able to save the parameter group after the change. As an area for storing saved data, a standard parameter area, a change parameter area, and an image quality adjustment ID area are reserved in the memory 20 for custom use (for example, C-1 to C-8). The custom areas can be provided in the memory 20 and the recording medium 27, respectively.

  For example, a case where a parameter group changed from the standard parameter group (default value) used in the VI image quality adjustment algorithm is stored in the custom area “C-3” will be described as an example. The changed parameter group (change value), that is, the change value stored in the VI change parameter area used in the VI image quality adjustment information and the VI default value stored in the standard parameter area are represented by “C -3 ”as a default value and stored in the standard parameter area, and an ID indicating the custom image quality adjustment algorithm (VI in this example) is stored in the image quality adjustment ID area. That is, ID information “VI” is stored in the image quality adjustment ID area “C-3”, and the parameter group at the time of registration used in the image quality adjustment algorithm for VI is stored in the standard parameter area “C-3”. (VI-based custom C-3 default value) is stored. When the registered custom setting parameter changing operation is performed, the changed parameter group is stored in the changed custom setting changing parameter area.

  When the changed parameter group is stored in the custom area, the electronic camera should use the stored parameter group in addition to the four image quality adjustment algorithms used for normal image quality adjustment and the added image quality adjustment algorithm. You can also. In the case of using a saved parameter group, the image quality adjustment algorithm to which the parameter group is applied is the image quality adjustment algorithm indicated by the image quality adjustment ID.

  The flow of the image quality adjustment setting described above will be described with reference to the menu screens exemplified from FIG. When the CPU 18 receives a pressing operation signal for the menu button (MENU) 201 (FIG. 2), the CPU 18 causes the liquid crystal monitor 21 to display a shooting menu screen illustrated in FIG.

<Picture control>
When the CPU 18 receives an upward or downward operation signal from the multi-selector 205, the CPU 18 moves the cursor up or down in accordance with the operation signal. When the CPU 18 receives a pressing operation signal of the execution button (OK) 204 in a state where the cursor is positioned on the “picture control” (FIG. 6), the list screen illustrated in FIG. 7 is displayed on the liquid crystal monitor 21.

  The “Picture Control” list screen (FIG. 7) is an operation screen for selectively using the four image quality adjustment algorithms described above as (normal image quality adjustment). In FIG. 7, four image quality adjustment algorithms “SD standard”, “NL neutral”, “VI vivid”, and “MC monochrome” are listed. If an image quality adjustment algorithm has been added, the added content is added to the display list.

  When the CPU 18 receives an upward or downward operation signal from the multi-selector 205, the CPU 18 moves the cursor up or down in accordance with the operation signal. When the CPU 18 receives a right operation signal from the multi-selector 205 in a state where the cursor is positioned on “VI Vivid” (FIG. 7), for example, the CPU 18 displays the adjustment operation screen illustrated in FIG. FIG. 8 is an operation screen for changing parameters.

  In FIG. 8, when receiving an upward or downward operation signal from the multi-selector 205, the CPU 18 moves the cursor up and down in accordance with the operation signal. Also, when a right or left operation signal from the multi-selector 205 is received, the content selected by the cursor is changed according to the operation signal. For example, when an operation signal in the right direction is received with the cursor positioned on “Quick Adjustment” (FIG. 8), the index on the “Quick Adjustment” bar is moved to the right (FIG. 9). When the CPU 18 receives a pressing operation signal of the execution button (OK) 204 in this state, the CPU 18 displays a list screen illustrated in FIG. 10 on the liquid crystal monitor 21.

  According to FIG. 10, “VI Vivid” is indicated by adding “*” to “VI Vivid”. This indicates that the standard parameter group (VI default value) has been changed, and the changed parameter group (changed value) has been stored in the changed parameter area. Here, “quick adjustment” refers to an adjustment in which a plurality of parameters (for example, edge enhancement, contrast, brightness, saturation, hue, and the like) are collectively controlled by a single item bar operation.

  Regardless of the “quick adjustment”, the corresponding parameter may be individually changed by moving the index on the bar for each parameter. For example, when a right operation signal is received in a state where the cursor is positioned on “contour emphasis” (FIG. 11), the index on the “contour emphasis” bar is moved in the right direction. The CPU 18 also displays the list screen illustrated in FIG. 10 on the liquid crystal monitor 21 when it receives a pressing operation signal for the execution button (OK) 204 in this state. The point that the standard parameter group (VI default value) is changed and the changed parameter group (changed value) is stored in the changed parameter area is the same as in the “quick adjustment” described above.

  When the CPU 18 receives a pressing operation signal of the execution button (OK) 204 while the list screen of FIG. 7 or FIG. 10 is displayed, the image processing circuit displays the image quality adjustment algorithm indicated by the cursor and the corresponding parameter group information. Set to 13. As a result, the image quality adjustment processing performed by the image processing circuit 13 reflects the setting contents set by the “picture control”.

  In the case where the operation screen illustrated in FIG. 8 or FIG. 9 is displayed, the CPU 18 resets the content of the change upon receiving a pressing operation signal for the delete button 206. Specifically, the parameter group after change (change value) stored in the change parameter area is deleted to return to the standard parameter group (VI default value in the above example). Since the standard parameter group is stored in the standard parameter area, the reset process is easy.

<Custom Picture Control>
When the CPU 18 receives a press operation signal of the execution button (OK) 204 in a state where the cursor is positioned on the “custom picture control” (FIG. 12), the menu screen illustrated in FIG. 13 is displayed on the liquid crystal monitor 21.

  The “custom picture control” operation screen (FIG. 13) is an operation screen for performing the above-described (addition of image quality adjustment algorithm) and (save parameter group after change). When the CPU 18 receives an upward or downward operation signal from the multi-selector 205, the CPU 18 moves the cursor up or down in accordance with the operation signal.

(Select parameter group)
When the CPU 18 receives a pressing operation signal of the execution button (OK) 204 in a state where the cursor is positioned on “edit and register” (FIG. 13), the list screen illustrated in FIG. 14 is displayed on the liquid crystal monitor 21.

  FIG. 14 is a list screen for selecting a parameter group to be edited / registered in “custom picture control”. In FIG. 14, four types of image quality adjustment algorithms “SD Standard”, “NL Neutral”, “VI Vivid *”, “MC Monochrome”, two types of parameter group information “C-2 FLOWER”, and “C-4” "SNOW SCENE" is listed.

  Here, “SD standard”, “NL neutral”, and “MC monochrome” represent respective standard parameter groups. “VI Vivid *” represents a parameter group changed by “Picture Control” described above. “C-2 FLOWER” and “C-4 SNOW SCENE” represent parameter groups registered by the procedure described below.

  When the CPU 18 receives an upward or downward operation signal from the multi-selector 205, the CPU 18 moves the cursor up or down in accordance with the operation signal. For example, when the CPU 18 receives a right operation signal from the multi-selector 205 in a state where the cursor is positioned on “VI Vivid *” (FIG. 14), the adjustment operation screen illustrated in FIG. 15 is displayed on the liquid crystal monitor 21. FIG. 15 is an operation screen for parameter change similar to FIG. With this operation screen, the parameters can be changed again before registration.

  When the CPU 18 receives a pressing operation signal of the execution button (OK) 204, the CPU 18 displays a list screen illustrated in FIG. In FIG. 16, “C-1” to “C-7” correspond to the above-described custom areas (C-1 to C-8 in FIG. 4). The CPU 18 executes the execution button in a state (FIG. 16) where the cursor is positioned on “unregistered” (for example, “C-3 unregistered”) excluding “C-2” and “C-4” that have already been registered. When a pressing operation signal of (OK) 204 is received, an operation screen illustrated in FIG. 17 is displayed on the liquid crystal monitor 21.

  The CPU 18 assigns a registered name in response to an operation signal from the multi-selector 205 or the like while displaying the registered name change screen of FIG. When the CPU 18 receives a pressing operation signal of the execution button (OK) 204, the CPU 18 registers a parameter group as “VIVID-2”, for example, and displays the operation screen of FIG. For example, when registering in the custom area C-3 and displaying a list screen similar to FIG. 14, “C-3 VIVID-2” is added to the display list.

  When the CPU 18 receives a pressing operation signal of the execution button (OK) 204 while the list screen of FIG. 14 is displayed, the CPU 18 sets the image quality adjustment algorithm indicated by the cursor and the corresponding parameter group information to the image processing circuit 13. To do. As a result, the image quality adjustment process performed by the image processing circuit 13 reflects the setting contents of the “custom picture control”.

  If the camera does not have an image quality adjustment algorithm to which the parameter group is applied, the CPU 18 excludes the parameter group from the display list in FIG.

(Save parameters to the recording medium)
When the CPU 18 receives a pressing operation signal of the execution button (OK) 204 in a state where the cursor is positioned on “use memory card” on the menu screen of “custom picture control” (FIG. 18), the menu illustrated in FIG. A screen is displayed on the liquid crystal monitor 21.

  FIG. 19 is an operation screen for selecting a process when the “memory card” is used. When the CPU 18 receives a pressing operation signal of the execution button (OK) 204 in a state where the cursor is positioned on “Copy to Memory Card” in the operation screen of FIG. 19, the list screen illustrated in FIG. 20 is displayed on the liquid crystal monitor 21. Let

  In FIG. 20, “C-1” to “C-6” are parameter groups stored by assigning registered names to custom areas (C-1 to C-8 in FIG. 4) provided in the memory 20. Represents. When the CPU 18 receives an upward or downward operation signal from the multi-selector 205, the CPU 18 moves the cursor up or down in accordance with the operation signal. When the CPU 18 receives the operation signal in the right direction from the multi-selector 205, the CPU 18 adds a check to the check box of the registered name where the cursor is located. The parameter group of the registered name to which the check is given becomes a copy target from the memory 20 to the recording medium 27.

  When the CPU 18 receives a pressing operation signal of the execution button (OK) 204 in a state where the cursor is positioned on “selection completed” (FIG. 21), the parameter group of the registered name to be copied is recorded as a custom image file. 27, and a message “Saved to memory card” is displayed on the liquid crystal monitor 21.

(Save parameters to the camera)
When the CPU 18 receives a pressing operation signal of the execution button (OK) 204 in a state where the cursor is positioned on “Register to camera” (FIG. 23) on the same operation screen as FIG. 19, the list screen illustrated in FIG. 24 is displayed. It is displayed on the liquid crystal monitor 21.

  In FIG. 24, “FLOWER”, “AUTUMN COLOR”, “SNOW SCENE”, “20070123”,... Represent custom picture adjustment files recorded with a registered name on the recording medium 27. The custom image adjustment file is a file including a parameter group, ID information indicating an image quality adjustment algorithm to which the parameter group is applied, and a standard parameter group in the image quality adjustment algorithm to which the parameter group is applied. When the CPU 18 receives an upward or downward operation signal from the multi-selector 205, the CPU 18 moves the cursor up or down in accordance with the operation signal.

  When a base image adjustment file including an additional image quality adjustment algorithm is stored in the recording medium 27, the registered name of the base image adjustment file is displayed together with the custom image adjustment file in the display list of FIG. In FIG. 24, “SEPIA DREAM” indicates an additional base image adjustment file. The file name display of the base image adjustment file and the file name display of the custom image adjustment file may be represented in different display forms. For example, a mark (* mark, etc.) is added to the base picture file name or the color is changed. The base image tone file is a file including a standard parameter group and an image quality adjustment algorithm to which the standard parameter group is applied.

  The CPU 18 excludes the base image adjustment file having the image quality adjustment algorithm added in the memory 20 from the display list of FIG. In addition, when the image quality adjustment algorithm to be applied is not included in the camera, the CPU 18 also excludes the custom image adjustment file including the parameter group applied by the image quality adjustment algorithm from the display list of FIG.

  For example, when the CPU 18 receives a right operation signal from the multi-selector 205 in a state where the cursor is positioned on “AUTUMN COLOR” (FIG. 24), the adjustment operation screen illustrated in FIG. 25 is displayed on the liquid crystal monitor 21. FIG. 25 is an operation screen for changing parameters. This operation screen allows the parameters to be changed again before saving to the camera.

  Unlike the case of changing the parameter group of the base image adjustment file (FIGS. 8 and 15), the adjustment operation screen for the parameter group of the custom image adjustment file is configured so that the item “Quick adjustment” cannot be selected.

  For example, when the CPU 18 receives a pressing operation signal of the execution button (OK) 204 in a state where the cursor is positioned on “AUTUMN COLOR” (FIG. 24), the contents of the image tone file of the registered name to be saved are stored in the memory 20. Record.

It is displayed on the monitor 21. When the additional base image adjustment file is stored in the memory 20, the CPU 18 displays the additional base image adjustment file on the liquid crystal monitor 21 together with the custom image adjustment file. However, if a custom image adjustment file based on the base image adjustment file exists in the memory 20, the base image adjustment file is excluded from the display list of FIG. This is to prevent the base image adjustment file from being deleted and a custom image adjustment file that cannot be used from remaining in the camera. Note that “standard”, “neutral”, “vivid”, and “monochrome” base image files other than the additional base image files stored in the memory 20 may also be deleted. However, in this case, if all the base image adjustment files are deleted, image processing cannot be performed in the camera body 200.

The name of the image quality adjustment is, for example, “Vivid”. The file description information is information relating to the file. The parameter group and the standard parameter group are as described above.

<Quick adjustment>
Of the operation screens for changing parameters illustrated in FIGS. 8, 9, and 15, “quick adjustment” will be described in more detail. In FIG. 8, FIG. 9, and FIG. 15, the index on the quick adjustment bar is configured to be movable in two stages on the left and right and five stages on the center (0). In this embodiment, for each of the five stages of quick adjustment, combinations of outline enhancement, contrast, brightness, saturation, and hue are determined in advance as illustrated in FIGS. 34 and 35 and stored in the memory 20. Keep it.

  The CPU 18 reads the table data of FIG. 34 or FIG. 35 according to the index position on the quick adjustment bar, and for each parameter of edge enhancement, contrast, brightness, saturation, and hue according to the read data, Change the adjustment values all at once.

  For example, when the quick adjustment is performed on the standard parameter group of the image quality adjustment algorithm “Vivid”, if the index on the quick adjustment bar is moved one step from the center (0) position to the right, the CPU 18 performs the quick adjustment shown in FIG. Data “5, +1, 0, +1, 0” corresponding to level “+1” is read. Then, the index on the “contour emphasis” bar is set to “5”, the index on the “contrast” bar is set to “+1”, the index on the “brightness” bar is set to “0”, and the index on the “saturation” bar is set. The parameter group is changed by moving the index to “+1” and the index on the “Hue” bar to “0”. The table data of FIG. 34 and FIG. 35 is determined so as to correspond to the index position on the bar when each parameter is individually changed.

  When performing “quick adjustment” after individually changing parameters using the operation screen illustrated in FIG. 11, there may be a contradiction with the individually changed parameter values. In this case, the CPU 18 displays the message illustrated in FIG. 36 on the liquid crystal monitor 21 and invalidates the parameter value individually changed when the execution button (OK) 204 pressing operation signal is received. Save the parameter setting value.

<Map display>
When the CPU 18 receives a pressing operation signal of the function button (F) 202 while displaying the “Picture Control” list screen (FIG. 7 or 10), the CPU 18 displays a map display indicating image quality adjustment on the liquid crystal monitor 21. FIG. 37 is a diagram illustrating a map display screen corresponding to the list screen of FIG. The map display represents the characteristics of image quality adjustment on a two-dimensional plane by representing the saturation on the horizontal axis and the contrast on the vertical axis in the parameter group. Such a two-dimensional planar display is also called a grid display.

  In FIG. 37, “V”, “N”, and “S” are displayed on the two-dimensional plane. “V” represents the contrast and saturation of standard parameters corresponding to the basic image tone file “Vivid”. Similarly, “S” represents the contrast and saturation of the standard parameter corresponding to the basic image file “Standard”, and “N” represents the contrast and saturation of the standard parameter corresponding to the basic image file “Neutral”. “M” corresponds to the basic image tone file “monochrome”. In the case of “monochrome”, since the saturation information is not included in the standard parameters, only the contrast information is represented at the right end of the two-dimensional plane.

  In the upper right part of the map display screen, image quality adjustment algorithms “SD” (standard), “NL” (neutral), “VI” (vivid), and “MC” (monochrome) are listed. Upon receiving an upward or downward operation signal from the multi-selector 205, the CPU 18 moves the cursor up and down on the list display in accordance with the operation signal. For example, the CPU 18 highlights “V” in the map display in a different manner compared to other “S”, “N”, and “M” in a state where the cursor is positioned on “VI” (Vivid) ( For example, black characters are displayed on a white background).

  When the CPU 18 receives a right operation signal from the multi-selector 205 while displaying the map display screen, the CPU 18 causes the liquid crystal monitor 21 to display the adjustment operation screen illustrated in FIG. When the CPU 18 receives a pressing operation signal for the function button (F) 202 while displaying the map display screen, the CPU 18 displays the list screen of FIG.

   FIG. 38 is a diagram illustrating a map display screen corresponding to the list screen of FIG. Compared to FIG. 37, the difference between “VI” (Vivid) and “VI *” (Vivid *) is shown. This is because the image quality adjustment by the standard parameter group (VI default value) and the image quality adjustment by the changed parameter group (change value) can be compared on a two-dimensional plane.

  The CPU 18 also displays a map display (grid display) indicating image quality adjustment when the function button (F) 202 is pressed during display of the “custom picture control” list screen (FIG. 14). To display. FIG. 39 is a diagram illustrating a map display screen corresponding to the list screen of FIG. Compared to FIG. 38, two types of parameter information “2” (C-2) and “4” (C-4) corresponding to the custom image adjustment file are added.

  When the CPU 18 receives a right operation signal from the multi-selector 205 while displaying the map display screen, the CPU 18 causes the liquid crystal monitor 21 to display the adjustment operation screen illustrated in FIG. When the CPU 18 receives a pressing operation signal for the function button (F) 202 while displaying the map display screen, the CPU 18 displays the list screen of FIG.

(Overlapping processing)
In the case of “custom picture control”, the parameter information of the custom picture adjustment file is displayed as a map in addition to the standard parameter information of the basic picture adjustment file. For this reason, when many custom image adjustment files are registered, the display content increases. FIG. 40 is a diagram illustrating a map display screen when a large number of custom image adjustment files are registered.

  FIG. 40 illustrates a case where three types of parameter information “6” (C-6), “7” (C-7), and “8” (C-8) are common on the map. In this case, the CPU 18 representatively displays only the parameter information “6” (C-6) on the map, and omits the map display of the parameter information “7” (C-7) and “8” (C-8). . The CPU 18 further connects “6” (C-6), “7” (C-7), and “8” (C-8) with a line in the list display on the right side of the screen. Represents something in common. When the common parameter information is representatively displayed, the information displayed at the top in the list display is preferentially displayed on the map.

(Priority display)
FIG. 41 is an excerpt of the map display portion for explaining the overlapping process. In the case of FIG. 41, two types of parameter information “2” (C-2) and “5” (C-5) corresponding to the custom image adjustment file are common on the map. The CPU 18 connects “2” (C-2) and “5” (C-5) with a line in the list display on the right side of the screen. At this time, by changing the list order of “5” (C-5) to “3” (C-3) and “4” (C-4), “2” (C-2 ) And “5” (C-5) are displayed continuously. In FIG. 41, since the cursor is positioned on “2” (C-2), “2” in the map display is preferentially displayed.

  FIG. 42 is a diagram illustrating a map display screen when the cursor is moved to “5” (C-5). In this case, “5” in the map display corresponding to the cursor position is preferentially displayed instead of preferentially displaying the one displayed at the top in the list display.

(Display showing auto setting)
In the parameter change operation screen, when the index on the bar is moved for each parameter as illustrated in FIG. 11 and FIG. 15, the “contrast” and “saturation” can be automatically set. The The CPU 18 automatically sets the parameter when the index on the bar is moved to the leftmost “A” position. When the “contrast” is automatically set, the CPU 18 automatically sets a parameter for determining the strength of the “contrast” from an image to be subjected to image quality adjustment processing. Further, when the “saturation” is automatically set, the CPU 18 automatically sets a parameter for determining “saturation” from an image to be subjected to image quality adjustment processing.

  When representing the above-described auto setting in the map display, the CPU 18 draws a line on the map to represent the auto setting. FIG. 43 is a diagram illustrating a map display screen when the parameter “contrast” is automatically set in the custom image adjustment file “3” (C-3). In addition to “3” in the map display, the line is displayed vertically.

  FIG. 44 is a diagram illustrating a map display screen when the parameter “saturation” is automatically set in the custom image tone file “3” (C-3). In addition to “3” in the map display, a line is displayed horizontally.

According to the embodiment described above, the following operational effects can be obtained.
(1) Since the electronic camera is configured so that the image quality adjustment algorithms [1] to [4] are used properly, compared to a case where only the parameters are changed for one image quality adjustment algorithm, the finish of the captured image is widened. Can be adjusted.
[1] Standard [2] Neutral [3] Vivid [4] Monochrome

(2) Since the standard parameter group applied to the image quality adjustment algorithm is configured to be changeable, the finish of the captured image can be finely adjusted.

(3) Since the changed parameter group is configured to be storable, the user-friendliness can be improved compared to the case where the parameter group disappears without being stored.

(4) Since the parameter group saved after the change can be changed and saved again, the user-friendliness can be further improved.

(5) Since the standard parameter group is saved together with the changed parameter group, the setting can be returned to the standard parameter group in accordance with the reset operation. Since it can be easily returned to the standard parameter group, it is convenient for the user. If the custom image adjustment is reset, the value stored in the standard parameter area of the custom image adjustment file, that is, the adjustment value at the time of custom image adjustment file registration is restored.

(6) When storing the changed parameter group (changed value), the ID information indicating the corresponding image quality adjustment algorithm is stored in addition to the standard parameter group, so that it is stored separately from the image quality adjustment algorithm. can do.

(7) The selection of the image quality adjustment algorithm [1] to [4] (picture control) and the selection of the changed parameter group (custom picture control) can be selected from the same list screen. (FIGS. 7 and 14), the finish setting of the captured image can be selected with a simple operation.

(8) When the image quality adjustment algorithm to which the parameter group is applied is not stored in the camera, the parameter group is excluded from the list display of FIG. As a result, it is possible to avoid a situation in which the parameter group is selected but cannot be applied to the image quality adjustment algorithm.

  Note that a (warning) message notifying that the image quality adjustment algorithm corresponding to the parameter group is not stored in the camera may be displayed on the liquid crystal monitor 21.

(9) A base image adjustment file including an image quality adjustment algorithm is stored in the memory 20, and a custom image adjustment file created based on the base image adjustment file is stored in the memory 20. In this case, the base image adjustment file is excluded from the deletion list in FIG. As a result, it is possible to avoid the possibility of creating a custom image adjustment file that cannot be used.

  Note that a message may be displayed on the liquid crystal monitor 21 to warn that a custom image adjustment file that cannot be used is generated before deleting the base image adjustment file.

(10) An image quality adjustment algorithm can be added to the electronic camera, and the content of the base image adjustment file is stored in the memory 20 in the camera from the recording medium 27 in which the base image adjustment file including the image quality adjustment algorithm for addition is stored. Recorded. An electronic camera to which an image quality adjustment algorithm has been added can be used to adjust the finish of captured images in a wider range if the image quality adjustment algorithms [1] to [4] used in normal image quality adjustment and the added image quality adjustment algorithm are used separately. can do.

(11) Since the [a3] image quality adjustment name, [a10] map information indicating image quality adjustment, and [a5] icon information are included in the basic image adjustment file, when adding an image adjustment algorithm to the electronic camera, The list screen can be displayed on the liquid crystal monitor 21 in an easy-to-understand manner for the user.

(12) Since the electronic camera is configured to be able to record the basic image file including the [a11] standard parameter group and the [a12] image quality adjustment algorithm on the recording medium 27, it is necessary for image adjustment from the electronic camera to the external device. Information can be provided easily.

(13) A parameter group to be applied to the image quality adjustment algorithm can be added to the electronic camera, and the contents of the custom painting file are stored in the camera from the recording medium 27 storing the custom painting file including the additional parameter group. The data was recorded in the memory 20. The electronic camera to which the parameter group is added can finely adjust the finish of the captured image by adjusting the image quality by applying the parameter group added to the image quality adjustment algorithm of the camera.

(14) Since the electronic camera is configured to be able to record the custom image adjustment file including the [b2] image quality adjustment ID, the [b5] parameter group, and the [b6] standard parameter group on the recording medium 27, the electronic camera is transferred to the external device. Information necessary for image adjustment can be easily provided.

(15) When changing the parameter group to be applied to the image quality adjustment algorithm, a “quick adjustment” for controlling a plurality of parameters (contour emphasis, contrast, brightness, saturation, hue) collectively by a single item bar operation. Made possible. Compared to the case where individual parameters are individually changed, the parameters can be changed easily.

(16) Since the “quick adjustment” and the adjustment method for individually changing each parameter can be selected, the user can adjust the parameter group by a favorite adjustment method.

(17) When “quick adjustment” is performed after individually changing the parameter group, a message is displayed on the liquid crystal monitor 21 to indicate that the changed contents are invalid (updated to the setting contents by the quick adjustment). Since it did in this way, a possibility that a parameter may change contrary to a user's will can be reduced.

  Even when the parameter group is individually changed after “Quick Adjustment”, a message to the effect that the contents changed by “Quick Adjustment” are invalid (updated to the setting contents by individual adjustment) is displayed on the LCD monitor 21. You may make it display.

(18) The characteristics of image quality adjustment can be shown on a two-dimensional plane centering on two of the parameter groups applied to the image quality adjustment algorithm on a map display in which corresponding parameter values are plotted. In particular, since the two axes are saturation and contrast, the characteristics of image quality adjustment can be expressed easily.

(19) Since the maps are displayed in correspondence with a plurality of image quality adjustment algorithms (basic image adjustments) and parameter groups (custom image adjustments), the difference in image quality adjustment can be easily expressed.

(20) When the plot positions overlap, the predetermined ones are preferentially displayed, so that a plurality of ones are not complicated and the characteristics of image quality adjustment can be easily expressed.

  In addition to displaying only the priority target, the priority display may display the priority target at the top and display other objects as shadows so that it can be seen that multiple objects overlap. Good.

(21) Since the higher-order items in the list are preferentially displayed or the items selected on the list are preferentially displayed, it is possible to display the characteristics of image quality adjustment regarding the basic image quality and custom image quality that the user wants to know.

(22) When the image quality adjustment algorithm is “monochrome”, only contrast information is represented, so that differences from other image quality adjustment algorithms (standard, vivid, etc.) can be expressed in an easily understandable manner.

(23) When parameters (saturation or contrast) corresponding to two axes are set automatically (when the electronic camera automatically determines parameters from an image to be subjected to image quality adjustment processing), a line is displayed on the map. As a result, the characteristics of image quality adjustment during auto setting can be displayed in an easy-to-understand manner.

  In addition, about the length of the line in the case of displaying a line, you may make it display by the length corresponding to the tolerance | permissible_range set automatically.
