Image display processing method and device thereof, display device and storage medium

An image display processing device, comprising:

• a regional eigenvalue acquisition circuit, configured to acquire a regional eigenvalue of each backlight block of an (n)th frame image and a regional eigenvalue of each backlight block of an (n−1)th frame image;
• an adjusted backlight luminance acquisition circuit, configured to perform a peak driving processing on a backlight luminance of each backlight block of the (n)th frame image, based on a preset threshold, the regional eigenvalue of each backlight block of the (n)th frame image and the regional eigenvalue of each backlight block of the (n−1)th frame image, so as to acquire an adjusted backlight luminance of each backlight block of the (n)th frame image;
• and
• an image displaying circuit, configured to display the (n)th frame image based on the adjusted backlight luminance of each backlight block of the (n)th frame image,
• wherein n is an integer greater than 1.

An image display processing device, comprising:

• a processor;
• a memory;
• and
• one or more computer program modules, being stored in the memory and configured to be executed by the processor, and comprising instructions to be executed for implementing an image display processing method for a display device, wherein the display device comprises a backlight unit, the backlight unit comprises a plurality of backlight blocks and is driven by a local dimming mode, and the image display processing method comprises:
• acquiring a regional eigenvalue of each backlight block of an (n)th frame image and a regional eigenvalue of each backlight block of an (n−1)th frame image;
• performing a peak driving processing on a backlight luminance of each backlight block of the (n)th frame image, based on a preset threshold, the regional eigenvalue of each backlight block of the (n)th frame image, and the regional eigenvalue of each backlight block of the (n−1)th frame image, so as to acquire an adjusted backlight luminance of each backlight block of the (n)th frame image;
• and
• displaying the (n)th frame image based on the adjusted backlight luminance of each backlight block of the (n)th frame image,
• wherein n is an integer greater than 1.
