Method and device for luminance adjustment, display device, and computer-readable storage medium

A display device, comprising:

• a display interface configured to receive an image data signal;
• and
• a controller connected to the display interface, wherein the controller is configured to:
• perform a luminance adjustment to a dynamic image according to a target adjustment mode when a received image data signal belongs to the dynamic image, wherein the target adjustment mode is a luminance adjustment corresponding to a sum of luminance components in the image data signal among a plurality of adjustment modes;
• wherein the plurality of adjustment modes comprise a first mode, a second mode and a third mode, and sums of the luminance components respectively corresponding to the first mode, the second mode and the third mode are sequentially increased;
• and
• a range of the luminance adjustment according to the first mode is larger than a range of luminance adjustment according to the second mode, and the range of luminance adjustment according to the second mode is smaller than a range of luminance adjustment according to the third mode.

A luminance adjustment device, comprising:

• a receiving circuit configured to receive an image data signal;
• a first adjustment circuit configured to perform a luminance adjustment on a dynamic image according to a target adjustment mode when the received image data signal belongs to the dynamic image, wherein the target adjustment mode is an adjustment mode corresponding to a sum of luminance components in the image data signal among a plurality of adjustment modes;
• wherein the plurality of adjustment modes comprise a first mode, a second mode and a third mode, and sums of the luminance components respectively corresponding to the first mode, the second mode and the third mode are sequentially increased;
• and
• a range of luminance adjustment according to the first mode is larger than a range of luminance adjustment according to the second mode, and the range of luminance adjustment according to the second mode is smaller than a range of luminance adjustment according to the third mode.
