Abstract: An image processing method, an anti-saturation method for image data and an image processing device are provided. The image processing method includes: analyzing an image frame to obtain an original gain value corresponding to grayscale values of the image frame, wherein the original gain value is greater than 1; obtaining a lookup table recording conversion relationship between default grayscale values and default gain values, wherein the lookup table is used for performing anti-saturation processing on image data of the image frame; according to the original gain value, performing anti-saturation processing for the image frame by using the lookup table to obtain an adjusted conversion relationship of the image frame, wherein the adjusted conversion relationship defines a conversion relationship between different grayscale values of the image frame and corresponding adjusted gain values; and performing gain processing on image data of the image frame according to the adjusted conversion relationship.

Abstract: An encoding method includes receiving a first data with a first length; dividing the first data into a plurality of data segments with a first specific length; obtaining at least one compressible data segment composed of identical data values if it exists and at least one uncompressible data segment composed of non-identical data values if it exists from the plurality of data segments; compressing the at least one compressible data segment to obtain at least one compressed data segment with a second specific length; generating an encoding data segment according to quantity and position of the at least one compressed data segment; and combining the at least one compressed data segment, the at least one uncompressible data segment and the encoding data segment to generate a second data with a second length, wherein the second specific length is shorter than the first specific length.
