Problems solved by technology

Due to the limitation of the metering of the single camera, in the backlight environment, the bright area is prone to appear white due to overexposure, while the dark area becomes black due to underexposure
If the background of the photographed image is overexposed or the foreground is too dark, it will seriously affect the visual effect of the image.
For example, when center metering is used, the exposure of

Abstract

A photographing method based on dual cameras is used in electronic equipment. The method comprises the steps as follows: acquiring first exposure of a first camera and second exposure of a second camera; adjusting first photographing parameters of the first camera according to the first exposure, and adjusting second photographing parameters of the second camera according to the second exposure; when receiving a photographing instruction, making the first camera photograph a target object to get a first image, and making the second camera photograph the target object to get a second image; and fusing the first image and the second image to generate a target image. The invention further provides a photographing system based on dual cameras. Through the method and the system, the problem that the background is over-exposed or the foreground target object is dark in a backlight scenario can be improved effectively, an accurately exposed image can be obtained, the image quality is optimized, the imaging effect is improved, and the user experience is enhanced.

Description

technical field [0001] The present invention relates to the technical field of digital image processing, in particular to a photographing method and system based on dual cameras. Background technique [0002] Nowadays, electronic devices have more and more functions, and the photographing function is one of them. The quality of the photographing effect is an important indicator for evaluating the quality of the electronic equipment. In the case of unsatisfactory lighting conditions, especially in the backlight environment, how to take a good image is particularly important. [0003] Traditional electronic devices use a single camera to take pictures. Due to the limitation of metering of a single camera, it is easy to appear that bright areas will become white due to overexposure in a backlight environment, while dark areas will become black due to underexposure. If the background of the photographed image is overexposed or the foreground is too dark, it will seriously affe...
