Image processing method and terminal

Abstract

The invention discloses an image processing method and a terminal. The method comprises steps: a black white image shot by a first camera of the terminal and a color image shot by a second camera of the terminal are obtained; sharp processing of the color image is carried out according to the black white image; black white image brightness information of the black white image and color image color information independent of the color image brightness information of the color image after sharp processing are extracted, synthesis of a color output image is carried out according to the black white image brightness information and the color image color information; the color output image is output. The picture shooting quality of the terminal can be raised.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an image processing method and a terminal. Background technique [0002] With the development of terminal technology, more and more functions can be implemented on terminals such as mobile phones and tablet computers, among which taking pictures is a popular function. At present, the terminal usually integrates a camera to realize the function of taking color photos through the terminal camera. In view of the pursuit of the shape of the terminal, the lens diameter of the camera usually cannot be made too large, which makes it difficult to increase the amount of light entering the camera. Therefore, at low When using the terminal camera to take pictures in an environment with high illumination, the flashlight is usually used to increase the brightness of the photo, but the light of the flashlight is directly on the scene. The parts are overexposed, leaving deep light ...

Problems solved by technology

At present, the camera is usually integrated on the terminal to realize the function of taking color photos through the camera of the terminal. In view of the pursuit of the shape of the terminal, the lens diameter of the camera cannot be made too large, which makes it difficult to increase the amount of light entering the camera. Therefore, at low When using the terminal camera to take pictures in an environment with high illumination, the flashlight is usually used to increase the brightness of the photo, but the light of the flashlight is directly on the scene. Parts are overexposed, leaving deep light traces, which will cause photo quality degradation
