Abstract
Techniques related to image dithering are described herein. The techniques include receiving an image to be displayed at a display device and entering a content adaptive backlight control mode. The image is dithered during the content adaptive backlight control mode. The dithering is disabled during a panel self-refresh mode.
Claims25
A system for dithering images to be displayed, comprising:
- a display device;
- and
- a dithering module, at least partially comprising hardware logic, wherein the logic of the dithering module is to:
- receive an image to be displayed at the display device;
- enter a content adaptive backlight control mode;
- dither the image during the content adaptive backlight control mode in response to a truncation of bit depth in the content adaptive backlight control mode;
- and
- disable dithering during a panel self-refresh mode.

A method for dithering images to be displayed, comprising:
- receiving an image to be displayed at a display device;
- entering a content adaptive backlight control mode;
- dithering the image during the content adaptive backlight control mode in response to a truncation of bit depth of the image with a fine color gradient in the content adaptive backlight control mode;
- and
- disabling dithering during a panel self-refresh mode.
2 more elements
A tangible, non-transitory, computer-readable medium comprising code to direct a processor to:
- receive an image to be displayed at the display device;
- enter a content adaptive backlight control mode;
- dither the image during the content adaptive backlight control mode in response to a truncation of bit depth in the content adaptive backlight control mode;
- and
- disable dithering during a panel self-refresh mode.
