Picture-taking method and system and machine readable medium

Abstract

The invention provides a photography method and system. Firstly, a first sensing image data is obtained from a surrounding light source. And then, a pre-flash is carried out by a flashlight, and a second sensing image data is obtained from the pre-flash of the flashlight. When a photography is operated, a white balance correction is carried out for each pixel in the sensing image according to the first sensing image data and the second sensing image data.

Description

technical field [0001] The present invention relates to a photographing method and system, and in particular to a photographing method and system capable of individually performing white balance correction for each pixel in an image in a dual light source including an ambient light source and a flash light source. Background technique [0002] With the progress of the times, the development of the camera has evolved from a traditional film camera to a digital camera in which the film is replaced by an image sensing unit, such as a charge-coupled device (CCD) or a complementary metal oxide semiconductor (CMOS). Since the digital photos taken by the digital camera can be easily viewed and processed in related devices, such as a computer system, the digital camera has become one of the must-haves in modern life. [0003] Generally, in a scene where the ambient light source is insufficient, such as indoors, a digital camera usually uses a flashlight to assist the exposure mechan...

AI Technical Summary

Problems solved by technology

Since the well-known methods cannot process different areas of the image separately, and cannot handle the situation of dual light sources at the same time, no matter whether the white balance correction is performed on the flash light source or the ambient light source, it will cause color shift in local areas of the image.
