1. An automatic gamma adjustment system with environmental adaptability, installed in a display device, and provided for automatically correcting a gamma value at any time according to surrounding situation to adjust grayscale layering presented to people, characterized in that:
the automatic gamma adjustment system with environmental adaptability comprises a signal receiving processor, a situation capture processor and a layering control processor, wherein the signal receiving processor selects an image signal source and receives and converts an image signal into a plurality of first YUV signals; the situation capture processor detects the surrounding situation, captures at least one environmental data, calculates the environmental data to obtain a gamma control parameter of a display screen of the display device, and the layering control processor calculates the environmental data to obtain a maximum brightness current value, while using the gamma control parameter to calculate and convert the first YUV signals into a plurality of second YUV signals, and transmitting the maximum brightness current value and the second YUV signals to the display device for the display screen to display an image according to the maximum brightness current value and the second YUV signals;
wherein, the environmental data comprises at least one of air quality, weather condition, and ambient brightness; the display screen is composed of a plurality of display panels, and the display device makes one of the display panels as a commander and rest of the display panels as followers, and after the display panel acting as the commander receives the second YUV signals and the maximum brightness current value transmitted by the layering control processor, the display panel acting as the commander drives the display panels acting as the followers to use the second YUV signals and the maximum brightness current value to display the image, such that the image displayed by the display screen shows a unified grayscale layering.
