Image color processing method and apparatus and terminal device

Abstract

The invention provides an image color processing method and apparatus and a terminal device. The method is used in the terminal device having a shooting function, and method comprises the following steps: controlling an image sensor by a micro electromechanical system to move and shot a first frame of image at an initial position; triggering the micro electromechanical system to move the image sensor from the initial position for two pixels along a preset first direction to a first position, and shooting a second frame of image at the first position; triggering the micro electromechanical system to move the image sensor from the first position for two pixels along a preset second direction to a second position, and shooting a third frame of image at the second position; and synthesizing a fourth frame of image according to color components corresponding to pixel positions in the first frame of image, the second frame of image and the third frame of image. Therefore, the image color reduction accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image color processing method, device and terminal equipment. Background technique [0002] Various terminal devices with shooting functions are widely used in daily life. When shooting, the terminal devices need to perform image color restoration processing on the images to be acquired, so as to obtain better quality captured images as much as possible. [0003] Since the true color of the image means that in each pixel value of a color image, there are three primary color components of R, G, and B, and each primary color component directly determines the primary color intensity of the display device to produce a color. However, the data format of the image sensor in the prior art is the bayer data format, and each pixel in this format has only one of the three color channels. Therefore, each pixel has only one real color component, and the others are m...

Problems solved by technology

However, the data format of the image sensor in the prior art is the bayer data format, and each pixel in this format has only one of the three color channels. Therefore, each pixel has only one real color component, and the others are missing. The color components need to be estimated by other processing methods, and the estimated color components and real color components are synthesized

[0004] Therefore, when the current terminal equipment takes pictures, the color of the acquired image is quite different from the color of the real picture, and the color reproduction of the image is not good.
