Problems solved by technology

If the brightness value extracted from the black and white photo is too high, the color in the combined photo will be lighter, resulting in an overexposed effect
If the brightness value extracted from the black and white photo is too low, the color in the combined photo will be darker, resulting in an underexposed effect

Abstract

A dual-camera synchronous exposure method is applied to electronic equipment comprising a first camera and a second camera. The method comprises the following steps: acquiring brightness information from a preview image collected by the first camera, calculating the saturation of the preview image, and calculating the quality of the preview image according to the saturation; updating the brightness information in the preview image according to the way of increasing the default step size, calculating the saturation of the preview image, and calculating the quality of the preview image according to the saturation until judging that the quality of the preview image declines; and when the quality of the preview image declines, calculating the exposure value of the second camera according to corresponding brightness information, and when detecting a shooting instruction of a user, making the first camera and the second camera carry out exposure shooting according to the exposure value. The invention further provides a dual-camera synchronous exposure system. The quality of composite images can be improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a dual camera synchronous exposure method and system. Background technique [0002] With the development of electronic equipment, terminals with a camera function have been popularized in people's lives. Terminals with more and more functions have greatly facilitated people's lives. In recent years, with the rapid development of image processing technology, the camera function of the terminal has become increasingly powerful, coupled with the advantages of the terminal being easy to carry, more and more users prefer to take pictures through the terminal. [0003] In order to improve the camera effect of terminals, more and more terminals adopt the solution of color plus black and white dual cameras. The solution of the color black-and-white dual-camera is to use two cameras to take images simultaneously, and then synthesize them in the later stage, so that the color in...
