Display apparatus, display control apparatus, and display control method

A display apparatus comprising:

• a display unit configured to display an image;
• a display control unit configured to cause the display unit to display an operation assist image having a color different from that of a display image by superimposing on the display image as a target to be displayed on the display unit;
• an image generation unit configured to generate the operation assist image so that a representative pixel value in each of one or more control blocks included in the display image is maintained and that the operation assist image has a color different from that of the display image in an assist image area for displaying the operation assist image, wherein the image generation unit generates the operation assist image by exchanging a pixel value of a color having a maximum pixel value in pixel values of three primary colors of the display image with a pixel value of one of other colors and changing pixel values of colors other than the color which has the maximum pixel value after exchanging the pixel values;
• and
• a light emission amount control unit configured to control a light emission amount of each of the one or more control blocks based on the representative pixel value,
• wherein the display control unit, the image generation unit, and the light emission amount control unit are implemented via at least one processor.

A method for controlling display, the method comprising:

• generating an operation assist image so that a representative pixel value in each of one or more control blocks included in a display image is maintained and that the operation assist image has a color different from that of the display image in an assist image area for displaying the operation assist image having the color different from that of the display image by superimposing on the display image as a target to be displayed on a display unit;
• controlling a light emission amount of each of the one or more control blocks based on the representative pixel value;
• and
• causing the display unit to display the operation assist image by superimposing on the display image while controlling the light emission amount,
• wherein, in the step of generating the operation assist image, the operation assist image is generated by exchanging a pixel value of a color having a maximum pixel value in pixel values of three primary colors of the display image with a pixel value of one of other colors and changing pixel values of colors other than the color which has the maximum pixel value after exchanging the pixel values.

A non-transitory computer-readable medium storing a program for causing a computer to execute a method for controlling display, the method comprising:

• generating an operation assist image so that a representative pixel value in each of one or more control blocks included in a display image is maintained and that the operation assist image has a color different from that of the display image in an assist image area for displaying the operation assist image having the color different from that of the display image by superimposing on the display image as a target to be displayed on a display unit, wherein the operation assist image is generated by exchanging a pixel value of a color having a maximum pixel value in pixel values of three primary colors of the display image with a pixel value of one of other colors and changing pixel values of colors other than the color which has the maximum pixel value after exchanging the pixel values;
• controlling a light emission amount of each of the one or more control blocks based on the representative pixel value;
• and
• causing the display unit to display the operation assist image by superimposing on the display image while controlling the light emission amount.
