Description

  The present invention relates to an imaging apparatus and a display method of a setting screen, and in particular, on a display unit that displays setting information such as operating conditions, a setting screen that can be confirmed by a color blind person without erroneous recognition. It can be displayed.

  An imaging apparatus such as a general digital still camera can change information (shooting size, image quality, shooting mode, etc.) that can be arbitrarily set by a user among various information used for operation via a setting screen. . This setting screen is displayed on a display unit included in the imaging apparatus using a predetermined layout.

The setting screen has a layout in which a plurality of colors are arranged and designed so that the visibility can be improved and the setting operation can be easily performed. This design is devised so that a user (normal color blind person) who can recognize a normal color has an easy-to-see color scheme. Therefore, these color schemes are not necessarily color schemes (displays) that are easy to see for users with color recognition problems (color blind people), and are displayed on the setting screen when color blind people use the digital camera. It is difficult to recognize various information, and thus may cause misrecognition and misconfiguration. In order to solve this problem, information regarding colors that tend to be misrecognized by color blind persons is registered in advance, and it is determined whether the image data displayed on the display unit includes the colors that tend to be misrecognized. When it is determined that such a color is included, an invention is known in which the corresponding color is converted into a predetermined color and displayed (for example, see Patent Document 1). Further, there is known an invention in which a user can switch to a predetermined screen for abnormal color vision by switching a healthy person / non-healthy person arbitrarily with a switch (see, for example, Patent Document 2).

  Multiple types of color vision abnormalities are known.For example, when it is difficult to recognize only a specific color, it is difficult to recognize the difference between colors when viewing multiple colors at the same time. Is difficult (all color blindness). Since there are various types of color blindness in this way, as described in Patent Document 1, even if a color-blind person uniformly converts a color that tends to be erroneously recognized into another color, a specific color vision The screen display is more difficult for an abnormal person to recognize. In addition, the user himself / herself may not be aware of his / her color vision abnormality tendency. Moreover, even when it is aware, it may be avoided that others know it. For such a user, there is resistance to explicitly switching a healthy person / non-healthy person as described in Patent Document 2 with a switch, and the function cannot be effectively used.

  Although the prevalence of imaging devices such as digital cameras is high, for men with color blindness who are statistically considered to be one in 20 men and one in 500 women, arbitrarily according to individual trends, In addition, there has been no imaging apparatus that can easily perform optimal screen display settings.

  Next, a flow of setting screen display processing in the imaging apparatus configured as described above will be described using a flowchart. FIG. 3 shows the flow of processing when the user presses the power button 6 of the imaging apparatus 1 and the operation of the imaging apparatus 1 is started, and the processing steps are S31, S32, S33. It is written like this. In FIG. 3, when the image pickup apparatus 1 is turned on, the color vision determination block 107 determines whether or not color vision replacement information is recorded in a predetermined storage area of the SDRAM 30 (S31). If the color vision replacement information is stored (Yes in S31), the color vision replacement information is read out, and a setting screen designed for a normal color vision person previously stored in another storage area in the SDRAM 30 is read out, A process of replacing the display color of each display area of the setting screen based on the color vision replacement information is performed (S32), and a setting screen in which the display color is replaced by the above process is displayed on the LCD 2 (S33). If color vision replacement information is not recorded in a predetermined storage area in the SDRAM 30 (No in S31), the display color of the setting screen designed for a normal color vision person stored in another storage area of the SDRAM 30 is replaced. It displays on LCD2 without doing (S33).

  FIG. 4 shows an example of a setting screen having a plurality of display areas. In FIG. 4, the setting screen 21 is an area (22) at the top of the screen for displaying information categories that can be set in order to make it easy for the user to recognize what information settings can be made. An area (23) for displaying setting item names that can be set on the screen, an area (24) for displaying values (setting values) already set for each setting item, and the operation types that can be selected on the screen are displayed. It has a region (25).

  When the cross key provided on the operation unit 3 is pressed while the setting screen 21 is displayed, the cursor on the setting item 23 can be moved, and the cursor is moved to the right of the cross key with the specific setting item 21 being moved. When the arrow is pressed, the setting item can be selected (FIG. 4B). When a setting item is selected, setting values that can be selected in this setting item are displayed (FIG. 4C). FIG. 4B shows a state in which the cursor is moved to the setting item “continuous shooting”, and FIG. 4C shows the “continuous shooting” item by pressing the right arrow of the cross key in FIG. The setting value that can be set in is displayed in a selectable manner. When the cursor is set to a specific setting value in the state of FIG. 4C and a “confirmation” operation (for example, pressing the “OK” button of the operation unit 3) is performed, this setting value becomes the setting item. Set as a value.

  As described above, the user can change the setting condition to the predetermined setting value via the operation unit while visually recognizing the operation condition of the imaging apparatus 1 on the information item displayed on the setting screen 21. The area needs to be displayed so that it is easy for the user to visually recognize and to easily distinguish each information item. Since the color arrangement layout design of such a setting screen is set in advance assuming a user with normal color vision, the display color of each display area of the setting screen 21 is set using the color vision replacement information. By replacing the display color with a combination that is easy for the user to recognize, an imaging apparatus that can be used by a wide range of users can be obtained.

  Next, the color vision replacement information generation process will be described with reference to the flowcharts of FIGS. In FIG. 5 and FIG. 6, each processing step is represented as S51, S52. First, when the “MENU” button provided in the operation unit 3 is pressed while the power of the imaging apparatus 1 is turned on, a setting screen (FIG. 4A) is displayed (S51). Here, when the cursor is moved to the information section area (22) and the right arrow of the cross key provided in the operation unit 3 is pressed, the “setup” menu is displayed. FIG. 7 shows an example of a setting screen in which the “setup” menu is selected. When the cursor is placed on one of the setting items “barrier free selection” (FIG. 7A) and the “OK” button is pressed, selectable setting values are displayed (FIG. 7B). The setting value displayed here is “Auto” or “Manual”.

  When “manual” is selected in the above processing (S53), the barrier free setting screen is displayed on the LCD 2 and the manual setting processing is started (S61 in FIG. 6). FIG. 8 shows an example of the barrier-free setting screen. In FIG. 8, the barrier-free setting screen 81 has a layout similar to that of the setting screen (FIG. 4) already described. An area ID 82 defined in advance in each display area of the setting screen and the area ID 82 A set color 83 which is a prescribed display color of the display area indicated by, and a color (barrier-free color) 84 which replaces the display color of the display area indicated by the area ID 82 are displayed. In FIG. 8A, the blank of the barrier-free color 84 indicates that a replacement color has not yet been set.

  In the state where the barrier-free setting screen 81 of FIG. 8A is displayed, the cursor is moved by operating the cross key of the operation unit 3 (FIG. 8B), and the area corresponding to the display area whose display color is to be replaced. When a selection operation is performed on the ID, candidate colors that can replace the area ID “5” and the setting color “orange” are displayed as shown in FIG. 8C, and a specific barrier-free color 84 is selected from these candidates. (S62). This process is repeated for the required set color. Incidentally, FIG. 8C shows a state in which the prescribed setting color “orange” is set to the replacement color “blue” in the area ID “5”.

  An example of the color vision replacement information generated in step S62 is shown in FIG. As shown in FIG. 9, the color vision replacement information 90 includes an area ID 91 corresponding to the area ID 82 displayed on the barrier-free setting screen, set color information (92) preset in the area ID 91, and the above processing. Is associated with the barrier-free color information 93 changed by. The example of FIG. 9 is an example in which the area ID “5” set in step S62 is changed to the barrier-free color information “blue” by the user's operation where the specified set color information is “orange”. .

  Based on the color vision replacement information, the display color of each display area of the setting screen (FIG. 4) is replaced, and the replaced setting screen (barrier-free screen) is displayed on the LCD 2 (S63). The user visually recognizes the barrier-free screen displayed on the LCD 2 and performs a confirmation operation if this screen display is acceptable. The color vision replacement information used on the setting screen (barrier free screen) displayed on the LCD 2 when the confirmation operation is performed is confirmed (Yes in S64), and this color vision replacement information is stored in a predetermined storage area of the SDRAM 30. (S65). If the barrier-free screen displayed on the LCD 2 is defective for the user, a cancel operation is performed and the barrier-free setting screen is displayed again on the LCD 2 (No in S64). In this way, the manual setting process can set display color replacement for each display area of the setting screen.

  Returning to FIG. When “Auto” is selected in step S53, the color vision test information is displayed on the LCD 2, and the auto setting process is started (S54). The displayed color vision test information is answered by operating the operation unit 3 (S55).

  FIG. 10 shows a display example of color vision test information. The color vision test is information used to determine a user's tendency to recognize color vision, and is configured by a combination of colors that are easily misrecognized by a color blind person. For example, it is information that can be displayed on the LCD 2 by simultaneously distinguishing combinations such as “red and green”, “red and black”, and “green and yellow” based on the three primary colors of red, blue, and green. As shown in FIG. 10, the test screen 101 for displaying the color vision test information has a screen layout in which the display area of the LCD 2 is divided into left and right parts. For example, the left display area is filled with “red”. The right display area is filled with “green”.

  After visually recognizing the display on the test screen 101, the user determines whether the colors of the left and right display areas are the same color, and inputs a determination result using the operation unit 3. This is an answer operation corresponding to the color vision test information. For example, in the color vision test of FIG. 10, when it is determined that the left and right colors displayed on the test screen 101 are “same”, the right arrow of the cross key provided in the operation unit 3 is pressed to make an answer, If it is recognized as “Different”, press the left arrow to answer. When it is recognized that the left and right colors are “same”, the “OK” button provided in the operation unit 3 is pressed, and when it is recognized as “different”, nothing is pressed and waits until a predetermined time elapses. The answer to the color vision test can be made by operations such as.

  Returning to FIG. The color vision determination block 107 determines whether or not the answer operation corresponding to the color vision test information in the above processing has been performed a sufficient number of times (for example, 10 times) to generate the color vision replacement information (S56). If the number of answer operations is insufficient to generate the color vision replacement information, the test screen 101 (FIG. 10) is displayed by changing the color combination using the next color vision test information (No in S56). .

  Based on the above answer operation, the barrier-free color information 93 is determined for each area ID 91 so that the color vision determination block 107 displays an optimal setting screen, and the color vision replacement information 90 is generated. Next, a barrier-free screen in which the color of each area of the setting screen (FIG. 4) is replaced based on the color vision replacement information 90 is displayed on the LCD 2 (S57). The user visually recognizes the barrier-free screen displayed on the LCD 2 and performs an operation of determining the color vision replacement information 90 if this screen display is acceptable (Yes in S58). When the confirmation operation is performed, the color vision replacement information 90 at that time is stored in the SDRAM 30 (S59).

  In step 58, when the user performs a canceling operation (for example, pressing the “MENU” button of the operation unit 3) when the barrier-free screen displayed on the LCD 2 is defective for the user (No in S58), processing is performed. Returning to step 57, the color vision determination block 107 determines another barrier-free color information 93 optimum for each display area, and a barrier-free screen based on the color vision replacement information 90 is displayed. Here, the displayed barrier-free screen is a screen using a combination of colors different from the previously displayed barrier-free screen. In a predetermined storage area of the SDRAM 30 of the imaging apparatus 1, various color combinations that are difficult for a person with color blindness to recognize are stored, and the color vision determination block 107 determines the color vision described above from the combination of these colors. Based on the test results, color vision replacement information that is estimated to be optimal is generated. In step 57, a barrier-free screen is displayed based on the color vision replacement information generated in this way.

  The color vision replacement information 90 generated by the above-described color vision test is a color substitution that uses a contrast color of “warm and cold colors” and “bright and dark colors”, and excludes pastel colors. Things, etc. In addition to this, it can be generated by various information such as setting an optimum character font together with colors so that brightness is given between the background and characters and characters are not displayed only by the hue difference. Also, in the color vision test, if there are color combinations with wrong answers (for example, when red and green are recognized as the same color), these misrecognized colors are not used at all, or either Color vision replacement information excluding colors is generated.

  Some users have extremely difficult color recognition, or some cannot recognize all colors. Such people are called "all color blind people". Even if all color blind persons perform the above-described color vision test, the barrier-free color information 93 that is easily visible in the color vision judgment block 107 cannot be determined. Therefore, when the color vision determination block 107 determines that the color vision test results in “all color vision abnormal”, it replaces all the colors used in the color vision test with gray scales that distinguish between black and white, and again, Perform the test.

  An example of gray scale is shown in FIG. FIG. 11A shows a case where black is displayed, in which all dots in a predetermined display area are filled (100% filling). FIG. 11B shows an example in which green is displayed, and 50% of the dots in a predetermined area are black, and the others are filled with white. FIG. 11C shows an example in which red is displayed, and 40% of the dots in a predetermined area are black and the others are filled with white. In this way, by replacing a specific color with black and white shading, it is possible to display a setting screen that can be identified even by all color blind persons. That is, as a result of the color vision test, the color vision judgment block 107 does not determine the name of a specific color for the barrier-free color name 93 but determines density information (60%, 40%) to generate color vision replacement information. That's fine.

  When displaying the setting screen based on the color vision replacement information 90 in which the density information of black and white dots is stored in the barrier-free color information 93 instead of the display color name, the setting color name information 92 is displayed as characters in each display area. Also good. By doing in this way, when a healthy person and a color blind person mutually confirm a setting screen, smooth recognition is attained without misunderstanding.

  In addition, the setting screen can be displayed based on the color vision replacement information 90 in which the hatched density is stored as shown in FIG. Further, as shown in FIG. 13, the density may be expressed in different shades for each area due to a difference in density of wavy lines used in a predetermined area.

  The present invention can also be applied to an imaging device that can be mounted on a camera-equipped mobile device and display processing of a setting screen thereof.
