Abstract
An image processing method, an image processing method device, a display device and a computer-readable storage medium are provided. The image processing method includes: receiving an original display screen; determining a target area in the original display screen, wherein an initial brightness of the target area is larger than a maximum allowable brightness; determining a target grayscale value of the target area; and adjusting a grayscale value of the target area to the target grayscale value, so that the brightness of the target area does not exceed the maximum allowable brightness.
Claims17
An image processing method, comprising:
- receiving an original display screen;
- determining a target area in the original display screen, wherein an initial brightness of the target area is larger than a maximum allowable brightness;
- determining a target grayscale value of the target area;
- and
- adjusting a grayscale value of the target area to the target grayscale value, so that the brightness of the target area does not exceed the maximum allowable brightness,
- wherein determining the target area in the original display screen comprises:
- if an average grayscale value of an area of the original display screen is larger than an average grayscale value of the original display screen, and a difference between the average grayscale value of the area and the average grayscale value of the original display screen is larger than a preset threshold, determining the area as the target area.
An image processing device, comprising:
- a receiving module configured to receive an original display screen;
- a first determining module configured to determine a target area in the original display screen, wherein an initial brightness of the target area is larger than a maximum allowable brightness;
- a second determining module configured to determine a target grayscale value of the target area;
- and
- an adjusting module configured to adjust a grayscale value of the target area to the target grayscale value, so that the brightness of the target area does not exceed the maximum allowable brightness,
- wherein the first determining module comprises:
- a first determining unit configured to determine an area as the target area if an average grayscale value of the area of the original display screen is larger than an average grayscale value of the original display screen, and a difference between the average grayscale value of the area and the average grayscale value of the original display screen is larger than a preset threshold.
An image processing method, comprising:
- receiving an original display screen;
- determining a target area in the original display screen, wherein an initial brightness of the target area is larger than a maximum allowable brightness;
- determining a target grayscale value of the target area;
- and
- adjusting a grayscale value of the target area to the target grayscale value, so that the brightness of the target area does not exceed the maximum allowable brightness,
- wherein determining the target grayscale value of the target area comprises:
- determining an initial brightness and a target brightness of the target area, wherein the target brightness is no larger than the maximum allowable brightness;
- and
- determining the target grayscale value according to a relationship between brightness and grayscale value, the initial brightness and the target brightness.
