Synchronous control method and synchronous control system for dual-camera exposure

Abstract

The invention discloses a synchronous control method and a synchronous control system for dual-camera exposure. The method includes step 1, correcting exposure uniformity of a primary camera and a secondary camera of a dual-camera module; step 2, acquiring Linecout parameter values and Again parameter values of the primary camera and the secondary camera of the dual-camera module as well as linearrelation between ambient brightness and exposure values according to a control variable method, and acquiring exposure linear scale parameters K1 and K2 of the primary camera and the secondary camerathrough measurement; step 3, adjusting exposure settings of the secondary camera according to the exposure linear scale parameters K1 and K2 of the primary camera and the secondary camera through variable control. The synchronous control method and the synchronous control system have the advantages that after the exposure uniformity of the primary camera and the secondary camera of the dual-camera module is acquired through judgment, the Linecout parameter values, the Again parameter values and the linear relation between the ambient brightness and the exposure values are acquired through measurement, the exposure linear scale parameters K1 and K2 are acquired, the exposure settings of the secondary camera are acquired through adjustment according to the relationship between the K1 and the K2, and accordingly, exposure synchronization is realized.

Description

technical field [0001] The present invention relates to the technical field of dual-camera applications, in particular to a dual-camera AE synchronization control method and system. Background technique [0002] As users have higher and higher requirements for mobile phone photography, and even require imaging capabilities comparable to SLR, but the current single camera cannot meet customer requirements. The solution is generally to use a higher pixel camera, but this will increase the number of responses. The cost of use is not conducive to improving the competitiveness of products. [0003] The dual camera can achieve fast focus, low light compensation, zoom and other functions very well. However, the synchronization of the current dual cameras is poor, which limits the development of the dual camera functions and is not conducive to maximizing the performance and advantages of the dual cameras.
