Image processing apparatus, display apparatus, image processing method, and image processing program
First Claim
1. An image processing apparatus comprising:
- an acquisition means that acquires image information corresponding to an image to be displayed on a display means, the image including at least an image of a document; and
processing means that performs luminance control processing that generates display image information by reducing at least luminance corresponding to a blue component in the acquired image information, the luminance control processing including reduction processing performed for each pixel of the image information so that a reduction rate of the luminance corresponding to the blue component in the acquired image information is greater than or equal to reduction rates of luminance corresponding to the other color components in the acquired image information and outputs the display image information to the display means to cause the display means to display the display image information;
wherein the reduction rate [%]=(1−
(output pixel value/input pixel value))×
100, assuming that each pixel value of the image information is 1 when the reduction processing is not performed;
wherein the display means acquires the display image information and displays the image corresponding to the display image information on an entire area of the display means; and
wherein the respective reduction rates in the acquired image information are different from a reduction rate of energy generated by the display.

Abstract
An image processing apparatus that can protect user'"'"'s eyes by reducing harmful blue light in a mode that matches the characteristics of an image to be displayed and the preference of the user who causes the image to be displayed. The image processing apparatus includes a blue light reduction control unit that acquires image information Sin corresponding to an image to be displayed on a display and a pixel value update unit that generates update image information Sbc by reducing at least luminance corresponding to a blue component in the acquired image information Sin so that a reduction rate of the luminance corresponding to the blue component is greater than or equal to reduction rates of luminance corresponding to the other color components in the acquired image information Sin and outputs the update image information Sbc to the display to cause the display to display the update image information Sbc.

13. An image processing method comprising:
-
providing display means; performing an acquisition step of acquiring image information corresponding to an image to be displayed on the display means, the image including at least an image of a document; and performing a processing step of generating display image information by reducing at least luminance corresponding to a blue component in the acquired image information, including luminance control processing comprising reduction processing performed for each pixel of the image, so that a reduction rate of the luminance corresponding to the blue component in the acquired image information is greater than or equal to reduction rates of luminance corresponding to the other color components in the acquired image information and outputting the display image information to the display means to cause the display means to display the display image information; wherein the reduction rate [%]=(1−
(output pixel value/input pixel value))×
100, assuming that each pixel value of the image is 1 when the reduction processing is not performed;wherein the display means acquires the display image information and displays the image corresponding to the display image information on an entire area of the display means; and wherein the respective reduction rates in the acquired image information are different from a reduction rate of energy generated by the display.

14. An image processing program causing a computer included in an image processing apparatus to function as:
-
an acquisition means that acquires image information corresponding to an image to be displayed on a display means, the image including at least an image of a document; and a processing means that generates display image information by reducing at least luminance corresponding to a blue component in the acquired image information, the processing means including luminance control processing comprising reduction processing performed for each pixel of the image information, so that a reduction rate of the luminance corresponding to the blue component in the acquired image information is greater than or equal to reduction rates of luminance corresponding to the other components in the acquired image information, wherein the reduction rate [%]=(1−
(output pixel value/input pixel value))×
100, assuming that each pixel value of the image information is 1 when the reduction processing is not performed, and outputs the display image information to the display means to cause the display means to display the display image information over an entire area of the display means, and wherein the respective reduction rates in the acquired image information are different from a reduction rate of energy generated by the display.
