Gamma correction method and device, display device, and computer storage medium

A gamma correction device, comprising:

• a processor and a memory,
• wherein the memory is configured to store a computer program;
• and
• the processor is configured to execute the computer program stored in the memory;
• the computer program comprises instructions for implementing following operations:
• acquiring measurement data of a first display panel, wherein the measurement data comprises m display brightness levels to be compensated and m sets of compensation parameters corresponding to the m display brightness levels, where m is a positive integer;
• and
