Embodiment Construction

[0020] see figure 1 , which is a hardware architecture diagram of the screen brightness adjustment system 2 provided by the present invention. The screen brightness adjustment system 2 mainly includes a display screen 4 , a brightness adjustment controller 6 for adjusting the brightness of the display screen 4 , an image capture device 8 and a synchronous signal generator 10 for coordinating the work of the image capture device 8 .

[0021] The image capture device 8 is a charge coupled device image sensor (CCD, Charge Coupled Device) or a complementary metal oxide semiconductor image sensor (CMOS, Complementary Metal Oxide Semiconductor). The image capturing device 8 can convert the external light into a digital signal corresponding to the intensity of the light.

[0022] The sync signal generator 10 provides a vertical sync signal with a period of 1 / 30 second. The vertical synchronization signal is used to coordinate the work of the image capture device 8, and the image ca...

Abstract

The invention relates to a system for adjusting screen brightness, which comprises a display screen, a brightness adjusting controller, an image acquiring device and a synchronous signal generator, wherein the brightness adjusting controller acquires the brightness change situation of the external environment by the image acquiring device so as to work out the screen brightness value suitable for the external environment and adjusts the brightness of the display screen according to the brightness value to obtain better visual effect.

Description

technical field [0001] The invention relates to a screen brightness adjustment system and method, in particular to a screen brightness adjustment system and method which can automatically adjust the screen brightness according to the brightness of the external environment. Background technique [0002] Many electronic imaging devices (such as digital cameras, digital video cameras, etc.) display captured images and various operating information through their built-in screens, and the brightness of the screens needs to be adjusted according to changes in the brightness of the external environment to obtain better visual effects. [0003] The built-in screen brightness adjustment function of existing electronic imaging devices is usually manually adjusted by entering the menu mode to find the screen brightness adjustment function options for fine-tuning operations. This adjustment method requires manual adjustment every time the brightness of the external environment changes, ...
