Title:
PICTURE DISPLAY CONTROL METHOD, APPARATUS, AND DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/217199
Kind Code:
A1
Abstract:
A picture display control method, apparatus, and device, and a medium. The method comprises the following steps: acquiring a video signal to be displayed (S10); performing frequency multiplication operation on the video signal on the basis of a preset frequency multiplication mode to obtain a frequency-multiplied signal corresponding to the video signal (S20); on the basis of a preset display parameter gamma table, determining a grayscale linear value corresponding to the frequency-multiplied signal (S30); on the basis of the grayscale linear value and the frequency multiplication mode, expanding a sequence unit frame of the video signal to obtain a frequency-multiplied sequence unit frame, so as to perform picture display (S40). The 3D video signal is subjected to frequency multiplication so as to obtain the corresponding grayscale linear value. The grayscale value of the display screen is improved by utilizing the frequency multiplication technology. Displaying is driven according to the frequency-multiplied grayscale linear value, thus optimizing the display performance of the display device, and enhancing the picture display quality of the display device.
