Problems solved by technology

In this case, although the texture blocks have 1 to 16 colors, since all the texture blocks are compressed with the same number of bits, it is less important to compress the color information related to all the colors included in the original uncompressed texture blocks. In other words, some texture blocks will have too many or not enough bits
As a result, some texels may have compressed unnecessary colors or may not be able to achieve the full range of colors contained in the original uncompressed texels

Abstract

The invention relates to a texture compressing method and apparatus and a texture decompressing method and apparatus. Provided are a texture compressing method and a texture compressing apparatus, which compress some color information of a texture block, which is unable to realize all colors included in the texture block by a determined compression bit number, to be stored in a compression data bit of a texture block, which is able to realize all colors included in the texture block by a bit number lower than the determined compression bit number, based on a color distribution of each textureblock, and a texture decompressing method and a texture decompressing apparatus corresponding to the texture compressing method and the texture compressing apparatus.

Description

[0001] This application claims the benefit of priority to Korean Patent Application No. 10-2016-0146948 filed with the Korean Intellectual Property Office on November 4, 2016, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] Various example embodiments relate to a texture compression method, system, apparatus and / or non-transitory computer readable medium. In addition, various example embodiments also relate to a texture decompression method, system, device and / or non-transitory computer-readable medium corresponding to the texture compression method and device. Background technique [0003] Multiple texture blocks used for image processing can form a texture, and all can be compressed with the same number of bits. When the size of the texture block is 4×4, one texture block includes 16 texels in total. In this case, although the texture blocks have 1 to 16 colors, since all the texture blocks are compressed with the same...
