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.
Therefore, the present invention is made in view of the above problem, and an example of the object of the present invention is to provide an image processing apparatus, a display apparatus, an image processing method, and a program for the image processing apparatus, which 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.
According to the seventh aspect of the present invention, in addition to the function according to the fifth aspect, in a case where an image corresponding to the acquired image information is achromatic color, the display image information is generated by reducing only an element other than the hue and the saturation in the color space, so that even in a case where the image is achromatic color, it is possible to protect user's eyes.
Therefore, it is possible to reduce the harmful blue component by image processing without separately using an optical member or the like that reduces the blue component, so that it is possible to protect user's eyes by reducing the harmful blue component 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.
Next, a second embodiment will be described with reference to FIGS. 8a to 14b . FIGS. 8a to 10b are figures explaining a principle and the like of the second embodiment, FIG. 11 is a block diagram showing a schematic configuration of a display apparatus according to the second embodiment, and FIGS. 12a and 12b are figures showing reduction processing of blue light according to the second embodiment. Further, FIG. 13 is a flowchart showing the reduction processing and FIGS. 14(a) and 14(b) are figures showing another example of the reduction processing. In the description below, the reduction processing of blue light according to the second embodiment is simply referred to as “reduction processing according to the second embodiment”.
First, an HLS color space and an HSV color space according to the second embodiment will be described with reference to FIGS. 8a and 8b . The HLS color space and the HSV color space are color spaces that have been generally known along with the RGB color space according to the first embodiment for image processing.
As described above, the present invention can be used in a field of display apparatus and if the present invention is applied to a field of control of display apparatus to protect user's eyes, a particularly remarkable effect can be obtained.
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;
2. The image processing apparatus according to claim 1, wherein the blue component is a B component in an RGB (Red Green Blue) color space and the other color components are an R component and a G component in the RGB color space; and
wherein the processing means generates the display image information by reducing the luminance corresponding to the B component so that the reduction rate of the luminance corresponding to the B component is greater than the reduction rates of the luminance respectively corresponding to the R component and the G component and outputs the display image information to the display means to cause the display means to display the display image information.
5. The image processing apparatus according to claim 1, wherein the blue component is a B component in hue in a color space including three elements including the hue, and saturation and the other color components are color components other than the B component in the hue; and
wherein the processing means generates the display image information by reducing the luminance corresponding to the B component so that the reduction rate of the luminance corresponding to the B component is greater than or equal to the reduction rates of the luminance corresponding to the color components other than the B component in the hue 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 is 1 when the reduction processing is not performed;
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.
