COMPUTER FOR CONTROLLING BRIGHTNESS OF MONITOR USING AUTOMATIC VOLTAGE CONTROL AND METHOD FOR CONTROLLING BRIGHTNESS OF MONITOR USING THIS

摘要

The present invention relates to a computer for controlling brightness of a monitor using an automatic voltage control and a method for controlling brightness of the monitor. More specifically, the present invention relates to a computer for controlling brightness of a monitor using an automatic voltage control and a method for controlling brightness of the monitor, in which changes in a graphic output signal (RGB) of a computer video output board is automatically detected, and a voltage of a video output device is automatically adjusted by analyzing an image signal through the arithmetic image processing of the corresponding screen, thereby reducing power consumption and preventing glare of the computer video output device actively To this end, the present invention includes: a video signal capture module for automatically detecting a change in color data of a real-time output image on a monitor screen and transmitting color data to a separate buffer space; a video signal analysis module for analyzing color data stored in a buffer space of the video signal capture module in the background; and a power control module for automatically adjusting an LED output voltage of a monitor in accordance with the color value of the color data calculated by the video signal analysis module.
