Abstract
The application relates to an image display control method and a display screen control system. The method includes: receiving an input image; performing luminance component mapping on target pixel data of the input image; converting the target pixel data after mapping from a luminance-chrominance separation color space to a primary color space; performing filtering on the target pixel data which are converted to the primary color space after mapping; and outputting the target pixel data after filtering to a display screen for image display.
Claims11
An image display control method, comprising:
- receiving an input image;
- performing luminance-component mapping on target pixel data of the input image;
- converting the target pixel data after the luminance-component mapping from a luminance-chrominance separation color space to a primary color space;
- performing filtering on the target pixel data which are converted to the primary color space after the luminance-component mapping;
- and
- outputting the target pixel data after the filtering to a display screen for image display.
A display screen control system, comprising a sending card, a receiving card and a light emitting diode (LED) display screen, and the receiving card being connected between the sending card and the LED display screen;
- wherein the sending card is configured for:
- receiving an input image;
- performing luminance-component mapping on the input image;
- converting the input image after the luminance-component mapping from a luminance-chrominance separation color space to a primary color space;
- performing filtering on the input image which is converted to the primary color space after the luminance-component mapping;
- and
- outputting the input image after the filtering to the receiving card to thereby drive the display screen for image display.
A display screen control system, comprising a sending card, a receiving card and an LED display screen, and the receiving card being connected between the sending card and the LED display screen;
- wherein the sending card is configured for:
- receiving an input image;
- and
- performing segmented probability statistics on pixel luminance component values of the input image;
- and
- wherein the receiving card is configured for:
- receiving probability statistical values;
- performing luminance-component mapping on pixel data of a local area of the input image, based on the probability statistical values;
- converting the pixel data of the local area after the luminance-component mapping from a luminance-chrominance separation color space to a primary color space;
- performing filtering on the pixel data of the local area which are converted to the primary color space after the luminance-component mapping;
- and
- outputting the pixel data of the local area after the filtering to the display screen for image display.
