Abstract

A display device and a display control method therefor. The display device includes a display interface, and the display control method includes: controlling the display interface to display at least two image windows in response to a start signal of a dyschromatopsia display mode, wherein the respective image windows are different in color mode of image content, and the color mode of the image content in at least one of the at least two image windows is a color mode suitable for being viewed by a dyschromatopsia sufferer; and in response to a signal generated by selecting one of the at least two image windows, controlling a color mode of the display interface to be the same as that of the image content in the selected image window.

First claim

The invention claimed is:

1. A display control method for a display device, the display device comprising a display interface, the display control method comprising:
controlling the display interface to display at least two image windows in response to a start signal of a dyschromatopsia display mode, wherein the respective image windows are different in color mode of image content, and the color mode of the image content in at least one of the at least two image windows is a color mode suitable for being viewed by a dyschromatopsia sufferer after an original image content is subjected to color conversion according to a distinguishing color feature of the dyschromatopsia sufferer; and
in response to a signal generated by a selection of one of the at least two image windows, controlling a color mode of the display interface to be the same as that of the image content in the selected image window, wherein the color mode of the image content in each of the image windows is a color mode after the original image content is subjected to color conversion according to a color vision compensation algorithm.

2. The display control method for the display device according to claim 1 , wherein the start signal of the dyschromatopsia display mode is a triggering command of the dyschromatopsia display mode.

3. The display control method for the display device according to claim 1 , wherein the signal generated by the selection of one of the at least two image windows is a triggering command in one of the at least two image windows.

4. The display control method for the display device according to claim 1 , wherein the controlling the display interface to display at least two image windows in response to the start signal of the dyschromatopsia display mode includes controlling the display interface to simultaneously display the at least two image windows in response to the start signal of the dyschromatopsia display mode.

5. The display control method for the display device according to claim 1 , wherein the controlling the display interface to display at least two image windows in response to the start signal of the dyschromatopsia display mode includes controlling the display interface to display the at least two image windows in a switching manner in response to the start signal of the dyschromatopsia display mode.

6. The display control method for the display device according to claim 1 , wherein the image contents displayed in the at least two image windows are all the same, except for color mode.

7. The display control method for the display device according to claim 1 , wherein the color vision compensation algorithm is based on a hexcone color space model (HSV).

8. The display control method for the display device according to claim 1 , wherein the original image content is a video stored in the display device.

9. The display control method for the display device according to claim 1 , wherein the original image content is a picture or video captured by a camera of the display device.

10. The display control method for the display device according to claim 1 , wherein before controlling the display interface to display the at least two image windows in response to the start signal of the dyschromatopsia display mode, the method further comprises:
controlling the display interface to display a mode selection menu including a normal display mode option and a dyschromatopsia display mode option.

11. A display device, comprising:
a display unit, comprising a display interface, configured to display two or more image windows in response to a start signal of a dyschromatopsia display mode, wherein the respective image windows are different in color mode of image content, and wherein the color mode of the image content in at least one of the two or more image windows is a color mode suitable for being viewed by a dyschromatopsia sufferer after original image content is subjected to color conversion according to a distinguishing color feature of the dyschromatopsia sufferer; and
a control unit, configured to, in response to a signal generated by a selection of one of the two or more image windows, control the color mode of the display interface of the display unit to be the same as that of the image content in the image window,
wherein, in the two or more image windows, the color mode of the image content in each image window is a color mode after original image content is subjected to color conversion according to a color vision compensation algorithm.

12. The display device according to claim 11 , wherein the display unit is further configured to display the two or more image windows simultaneously in response to the start signal of the dyschromatopsia display mode.

13. The display device according to claim 12 , wherein the image contents displayed by the two or more image windows are all the same, except for color mode.

14. The display device according to claim 11 , wherein the display unit is further configured to display the two or more image windows in a switching manner in response to the start signal of the dyschromatopsia display mode.

15. The display device according to claim 11 , wherein the color vision compensation algorithm is based on a hexcone color space model (HSV).

16. The display device according to claim 11 , wherein the original image content is a video stored in the display device.

17. The display device according to claim 11 , wherein the display device further includes a camera, and the original image content is a picture or a video captured by the camera of the display device.

18. The display device according to claim 11 , wherein the display unit is further configured to, before displaying the two or more image windows, display a mode selection menu including a normal display mode option and a dyschromatopsia display mode option.
