Problems solved by technology

like figure 1 It can be seen that the traditional screen brightness adjustment method is to uniformly adjust all the pixels of the screen, and the image blocks that do not need to be changed in brightness will also be adjusted together, which is likely to cause the disadvantage of unstable image quality

Embodiment Construction

[0041] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0042] see figure 2 , figure 2 It is a functional block diagram of the display 10 of the embodiment of the present invention. The display 10 includes a panel unit 12 and a controller 14 electrically connected to each other. The controller 14 drives the panel unit 12 to display images according to the received data from the host. When the display 10 displays an image from a bright place to a dark place, it is usually difficult for the user to see part of the high-brightness block icons or other corresponding patterns in the dark background in the image due to the sudden light-dark transition of the visual field, so the controller 14. By analyzing the grayscale distribution map of the image, the high-brightness block icon of this part can be found, and it can be ju...

Abstract

The invention provides an image adjusting method. The image adjusting method comprises the following steps: generating a gray scale distribution diagram of an image; at least dividing the gray scale distribution diagram into a first region and a second region, wherein the gray scale value of the first region is greater than that of the second region; comparing the pixel amount of the first region with a threshold value; utilizing a modified function to adjust the pixel brightness of the first region according to the comparative result; when the pixel amount of the first region is greater than the threshold value, utilizing the modified function to reduce the pixel brightness of the first region.

Description

technical field [0001] The invention provides an image adjustment method and a display, especially an image adjustment method and a display capable of adjusting the brightness of a picture by detecting gray scale distribution. Background technique [0002] With the advancement of technology, the previous mainframe computer was designed as a personal computer suitable for use in family life. Personal computers provide consumers with access to the Internet, execution of application software and / or gaming software for entertainment. When a personal computer is running game software, the display screen may have rapid regional brightness changes along with the game content. However, consumers' eyesight is usually difficult to adapt to the rapid brightness change of the screen, such as the traditional display screen suddenly changing from a bright scene When it comes to the dark color background, it will be difficult for consumers to recognize the displayed image in the dark colo...
