Abstract
A power-saving image display system includes a visual feature analyzer that receives input image data and generates a visual feature ratio representing a brightness ratio of a full image to a feature area; a visual feature spatial gain device that generates visual feature spatial gains according to the visual feature ratio and original spatial gains; and a brightness adjustment device that adjusts brightness values of the input image data according to corresponding visual feature spatial gains, thereby generating output image data.
Claims11
A power-saving image display system, comprising:
- a visual feature analyzer implemented by a circuit or processor coupled to receive input image data and configured to generate a visual feature ratio representing a brightness ratio of a full image to a feature area and being defined as a ratio of an average brightness of the full image to an average brightness of the feature area;
- a visual feature spatial gain device that generates visual feature spatial gains according to the visual feature ratio and original spatial gains;
- and
- a brightness adjustment device that adjusts brightness values of the input image data according to corresponding visual feature spatial gains, thereby generating output image data.
