  • Method and device for enhancing brightness and contrast of video image
    Patent number: 11205252
    Abstract: A method and a device for enhancing brightness and contrast of a video image are provided. In the method, an inflection point, a truncation point, a maximum value of a brightness component, and a minimum value of the brightness component of an image frame to be processed are determined based on the brightness component of the image frame to be processed, a piecewise linear function is determined based on the inflection point, and brightness and contrast enhancement processing is performed on the image frame to be processed based on the piecewise linear function. Compared with the brightness and contrast enhancement method in conventional art, the method and device of the application can achieve better brightness and contrast enhancement effects.
