Brightness determination method, device, display panel, electronic equipment, and storage medium

A brightness determination device, used for a display panel, wherein the display panel comprises a plurality of pixels, the brightness determination device comprises:

• a first determination module, configured to determine, based on an image to be displayed, first display brightness values corresponding to the plurality of pixels respectively;
• a second determination module, configured to determine a reference average picture level corresponding to the image to be displayed based on the first display brightness values corresponding to the plurality of pixels respectively;
• and
• a third determination module, configured to determine a target maximum display brightness value corresponding to the display panel during display of the image to be displayed based on the reference average picture level and information about a relationship between an average picture level and a maximum display brightness value,
• wherein a value range corresponding to the average picture level comprises at least two segment intervals, the information about the relationship comprises information on variation of the maximum display brightness value with the average picture level in the at least two segment intervals;
• in different segment intervals, the maximum display brightness value varies at different rates with the average picture level;
• in at least one of the segment intervals, the maximum display brightness value decreases as the average picture level increases.

An electronic equipment, comprising:

• a processor;
• a memory, configured to store one or more computer program modules;
• wherein the one or more computer program modules are configured to be executed by the processor, and the one or more computer program modules comprise instructions for implementing a brightness determination method;
• the brightness determination method is used for a display panel, the display panel comprises a plurality of pixels, the method comprises:
• determining, based on an image to be displayed, first display brightness values corresponding to the plurality of pixels respectively;
• determining, based on the first display brightness values corresponding to the plurality of pixels respectively, a reference average picture level corresponding to the image to be displayed;
• and
• determining, based on the reference average picture level and information about a relationship between an average picture level and a maximum display brightness value, a target maximum display brightness value corresponding to the display panel during display of the image to be displayed,
• wherein a value range corresponding to the average picture level comprises at least two segment intervals, the information about the relationship comprises information on variation of the maximum display brightness value with the average picture level in the at least two segment intervals;
• in different segment intervals, the maximum display brightness value varies at different rates with the average picture level;
• in at least one of the segment intervals, the maximum display brightness value decreases as the average picture level increases.
