Problems solved by technology
[0005] Due to the above disadvantages in the existing color depth conversion method, when the image obtained by using the color depth conversion method is transmitted in layers, although the number of color depth bits of the image obtained by the terminal matches the display capability of the terminal, the obtained image Compared with the original image, the color distortion is serious, resulting in a poorer image effect actually viewed by the user

Embodiment Construction
[0035] The color components involved in the embodiment of the present invention refer to the red (R) color component, green (G) color component and blue (B) color component in a pixel point. Each color component occupies a certain number of color depth bits, and the sum of the color depth bits of the three color components is the image color depth bits. The value range of the color component value of each color component is: 0~(2 (占用的色深位数) -1). For example, for an image with a 16-bit color depth, the color depth bits of the R color component, G color component, and B color component can be 6, 5, and 5, and the value range of the R color component value is 0 ~2 6 -1. The value range of G color component value is 0~2 5 -1. The value range of B color component value is 0~2 5 -1.
[0036] The solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

The invention discloses a method and a device for transforming color depth of an image. The method comprises the following steps: determining a first color area in the image, and selecting a dominant color component from the first color area, wherein the first color area is a significant color area of the image; and transforming color depth digits of the image into set color depth digits, whereinin the first color area of the image after transformation, the selected color depth digits of the color component are not smaller than that of other color components. Through the method and the device, the color distortion of the image after the transformation of the color depth digits is smaller and the image is closer to the original image. The invention also discloses a method, a system and a device for performing transmission by using the obtained image after transformation.
Description
technical field [0001] The present invention relates to computer technology and data transmission technology in the field of communication, in particular to a method and device for color depth conversion of images, and a method, system and device for transmitting images after color depth conversion. Background technique [0002] The image display capabilities of various terminals such as mobile terminals and PC terminals are quite different, ranging from images that support 16-color images that are 4-bit color depth, 256-color images that are 8-bit color depth images, and 65,000-color images that are 16-bit color images. 24-bit color depth images ranging from 16 million color images to 24-bit color depth. With the continuous development of network value-added services, the demand for terminals to obtain images from the network or one terminal to obtain images from another terminal is gradually increasing. However, the color depth bit of the image acquired by the terminal ma...
