Abstract
A processing method for a plurality of image sources, for a display device includes inputting a plurality of image sources; detecting the plurality of image sources according to metadata of the a plurality of image sources to determine electro-optical transfer function (EOTF) corresponding to the a plurality of image sources; and dynamically applying different EOTFs on corresponding image sources.
Claims18
A processing method a display device, comprising:
- inputting a plurality of image sources of the display device;
- detecting the plurality of image sources according to metadata of the plurality of image sources to determine whether each of the plurality of image sources is High Dynamic Range (HDR) image source or not;
- when a first image source of the plurality of image sources is HDR image source, determining a first electro-optical transfer function (EOTF) corresponding to the first image source and applying the first EOTF on the first image source;
- when a second image source of the plurality of image sources is HDR image source, determining a second EOTF corresponding to the second image source and applying the second EOTF on the second image source;
- when the second image source of the plurality of image sources is not HDR image source, applying a Gamma correction on the second image source;
- displaying images from the first image source and the second image source in a screen image of the display device, wherein the first EOTF is applied to the first image source, and the second EOTF or the Gamma correction is applied to the second image source;
- detecting, respectively, a moving vector of a first frame and a second frame of the first image source;
- determining a pixel difference between the first frame and the second frame of the first image source according to the moving vector of the first frame and the second frame;
- and
- performing a smooth filtering for the first image source when the pixel difference between the first frame and the second frame of the first image source exceeds a default value;
- wherein the smooth filtering for the first image source includes image blending according to a similarity ratio of the first frame and the second frame of the first image source.
