Problems solved by technology

[0006] In the prior art, each static image memory that stores indirectcolor images needs its own color table memory; assuming that the static image memory only stores indirectcolor images in 8bpp image format, then two static image memories require 2×1024byte storage space, and three The static image memory needs 3×1024byte storage space, when the number of static image memory is large, it will cause a huge waste of chip storage space

Embodiment Construction

[0061] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0062] The storage of indirectcolor images is further described below.

[0063] The indirectcolor image stores its own color in the color table and the image respectively. The color table usually uses 32bit to represent a color, for example, 00000000 represents black, 00ffffff represents white, etc.; and, in order to save the storage space of the indirectcolor image, the image will use The image value replaces the 32 bits, for example, 01 is used to represent 00000000, and 02 is used to represent 00ffffff, that is, the image value establishes a mapping relationship from the image to the color table.

[0064] Specifically, users often establish the mapping relationship based on specific indirectcolor images. Therefore, the color ta...

Abstract

The invention provides a method and device for storing an indirect color image, and an image displaying method and device, wherein the storage method concretely comprises the following steps of: establishing a color table template, wherein the color table template comprises a plurality of color values; establishing mapping from the indirect color image to the color table template by amending the image numerical value of the indirect color image; storing the color table template into a color table memory, and storing the image numerical value of the amended indirect color image to a corresponding static image memory. The storage space of chips can be saved.

Description

technical field [0001] The present invention relates to the technical field of image storage, in particular to an indirect color image storage method and device, and an image display method and device. Background technique [0002] The indirect color (indirectcolor) image is a very important mode. The image can specifically include 4 image formats: 1bpp (image pixel depth, bitsperpixel), 2bpp, 4bpp, 8bpp, and the image generally consists of 2 parts, one part is The color table, and the other part is the value. When applying the image, just look up the color corresponding to the read value in the color table according to the image format. [0003] Due to the advantage of small amount of information, in particular, with the gradual popularization of portable electronic products in recent years, the indirect color image is widely used in image display of portable electronic products such as mobile phones and cameras. [0004] refer to figure 1 , shows a schematic structural ...
