Problems solved by technology

[0006] Embodiments of the present invention provide a method and device for reducing video memory, which solves the problem of the storage mode of each pixel in the decoded bitmap due to the ARGB_8888 decoding method used for decoding when the existing display device displays the bitmap. It is also ARGB_8888, but there is a problem of wasting storage space

Abstract

Embodiments of the invention provide a display memory reduction method and apparatus, relate to the technical field of data storage, and solve the problem of storage space waste caused by the fact that a storage mode of each pixel in a decoded bit map is ARGB_8888 due to adoption of a decoding mode of ARGB_8888 for performing decoding when an existing display device displays the bit map. According to the specific scheme, the method comprises the steps of determining an attribute of an image; if the attribute of the image represents that the image does not contain transparency and is a grayscale image, storing the image in a display memory in a first storage mode, wherein the first storage mode is a storage mode that each pixel point in the image occupies 2m bits; or otherwise, storing the image in the display memory in a second storage mode, wherein the second storage mode is a storage mode that each pixel point in the image occupies 2n bits, and n is greater than m.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a method and device for reducing video memory. Background technique [0002] In the prior art, there are four commonly used storage methods after bitmap decoding, namely ARGB_4444: that is, A=4, R=4, G=4, B=4, then one pixel occupies 4+4+4+ 4=16 bits, that is, occupying 2 bytes of memory; ARGB_8888: that is, A=8, R=8, G=8, B=8, then one pixel occupies 8+8+8+8=32 bits, that is, occupies 4 bytes of memory; RGB_565: that is, R=5, G=6, B=5, without transparency, then a pixel occupies 5+6+5=16 bits, that is, occupies 2 bytes of memory; ALPHA_8: only transparency , no color, then a pixel occupies 8 bits, that is, occupies 1 byte of memory. It can be seen that the ARGB_8888 storage method occupies the most memory. The higher the median of the storage method, the more color information it can store, and of course the more realistic the image. [0003] Among them, the storage met...
