Method and system for verifying synchronous exposure of camera and electronic equipment

Abstract

The invention discloses a method and a system for verifying synchronous exposure of a camera and electronic equipment. The method for verifying synchronous exposure of the cameras comprises the following steps of obtaining at least two groups of identification images obtained by simultaneously shooting a marker through at least two cameras, the marker being changed at an interval of a predetermined time, and the identification images of different frames in each group of identification images comprising different images of the marker, identifying the image of the marker contained in the identification image of the corresponding frame in the at least two groups of identification images to obtain a time difference between the identification images of the corresponding frame; and judging whether the time difference between the identification images of the corresponding frames is less than a time threshold, if so, judging that the at least two cameras are synchronously exposed, and if not,judging that the at least two cameras are not synchronously exposed.

Description

Technical field [0001] The present invention relates to the field of camera technology, in particular to a method for verifying the synchronous exposure of a camera, a system and electronic equipment thereof. Background technique [0002] With the rapid development of science and technology, people have higher and higher requirements for camera quality, and single cameras are gradually unable to meet people's needs. Subsequently, dual cameras and even multiple cameras have entered people's field of vision. As we all know, dual-camera or multi-camera not only helps to improve the quality of the camera, but also can determine the distance of the subject through the algorithm, so this feature can easily make such as background blur, background replacement, background special effects, distance measurement , Optical zoom and so on. However, since the synchronization of dual cameras or multiple cameras is a prerequisite for achieving the above effects, whether the cameras are synchro...

Problems solved by technology

Because this time stamp is the time stamp in the ISP (Image Signal Processing, Image Signal Processor) processing stage, not the time stamp of the exposure moment in the strict sense, and camera synchronization refers to the simultaneous exposure of dual cameras or multiple cameras, so the prior art There is an imprecise problem in the synchronous verification method, which will inevitably introduce errors, resulting in inaccurate verification results
