Problems solved by technology

However, when the display image produced by the display device is a high-brightness image (such as an image of snow), this method will only cause the display image to be saturated, that is, the entire display screen is almost white, and Causes the user to be unable to see the details in the displayed image

Embodiment Construction

[0033] Please refer to figure 1 , figure 1 A schematic diagram of a display device according to an embodiment of the present invention is shown. The display device includes an ambient light detector 110 , a display image content analyzer 120 and an image compensation processor 130 . The ambient light detector 110 detects the ambient light brightness EL, and generates an ambient light brightness level ELG according to the ambient light brightness EL. The displayed image content analyzer 120 then receives the displayed image data IMGD. The display image content analyzer 120 determines the brightness of the display image data IMGD by analyzing the gray scale values ​​of all the pixel data in the display image data IMGD. The display image content analyzer 120 generates the display image data brightness level IMGDG according to the determined brightness of the display image data IMGD.

[0034] Please note here that the ambient light detector 110 divides the ambient light bright...

Abstract

The invention discloses a display device and an image compensation method thereof. The display device comprises an ambient light detector, a display image content analyzer and an image compensation processor, wherein the ambient light detector detects the ambient light brightness and generates the ambient light brightness grade according to the ambient light brightness; the display image content analyzer receives and analyzes the display image data and generates the display image data brightness grade according to the brightness of the display image data; the image compensation processor generates an image brightness enhancement value, an image color compensation value and an image edge enhancement degree according to the ambient light brightness grade and the display image data brightness grade; and the image compensation processor performs image processing on the display image data according to the image brightness enhancement value, the image color compensation value and the image edge enhancement degree to generate the image data after compensation.

Description

technical field [0001] The invention relates to an image compensation method of a display device, and in particular to an image compensation method performed by the display device as the environment brightness changes. Background technique [0002] In known technologies, it is common for a display device to correspondingly adjust the brightness of a displayed image according to the brightness of ambient light. In this known method, in a high-resolution display device, in order to increase the brightness of the displayed image, it means that the brightness of the backlight module of the display device must be increased, or the thickness of the color filter of the display device shall be reduced to Improve light transmittance. However, increasing the brightness of the displayed image by increasing the brightness of the backlight module of the display device will greatly increase the power consumption of the display device. However, reducing the thickness of the color filter ...
