Embodiment Construction
[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0040] There are many kinds of bit extension algorithms in the prior art. For simple bit extension algorithms, the problem of color scale and false contour will be introduced, and for the bit extension algorithm that can solve the problem of color scale and false contour, it will take up a lot of time and complexity. degree, computational complexity, and storage consumption. At present, there are more and more applications of wireless terminal devices, such as...

The invention provides an image display processing method, an image display processing device and an image display system. The method comprises the following steps of receiving an input image with a bit width as a first bit width, bit extending the input image, and forming an extending image corresponding to the input image; generating a high-frequency noise image according to the extending image; respectively adding pixel values of all pixel points in the extending image and pixel values of pixel points at corresponding positions in the high-frequency noise image through channels, and forming pixel values of all pixel points in an output image; outputting and displaying the output image. Compared with the prior art, according to the method, on the basis of ensuring the effects of color gradation and false outline elimination, the complexity and the storage consumption of an algorithm are remarkably reduced, so that the image display processing efficiency is remarkably improved.
Description
technical field [0001] The present invention relates to image display technology, in particular to an image display processing method, device and image display system. Background technique [0002] Current image display systems support various bit widths, such as 8-bit bit width, 10-bit bit width, and so on. There are also various bit widths of images that need to be displayed in the image display system, such as 8-bit bit width, 10-bit bit width, and the like. If an image with a bit width of 8 bits is directly displayed on a 10-bit image display system, problems such as color scale and false contours will appear. [0003] In the prior art, in order to eliminate problems such as color scale and false contours caused by different bit widths, it is necessary to perform bit extension processing on the image before the image is displayed or used. Specifically, the extended bit data is calculated by a specific algorithm, so that the bit width of the image is consistent with the...
