Abstract

The invention discloses a dual camera exposure synchronization control method and system, wherein the method includes: step 1, correcting the exposure consistency of the main and secondary cameras of the dual camera module; Measure the linear relationship between the linecount parameter value, Again parameter value and ambient brightness and exposure value of the primary and secondary cameras of the group, and obtain the exposure linear ratio parameters k1 and k2 of the primary and secondary cameras; step 3, according to the exposure linear ratio parameters k1 and k2 of the primary and secondary cameras , adjust the exposure settings of the secondary camera by controlling variables. The dual-camera exposure synchronization control method and system, after obtaining the exposure consistency of the main and secondary cameras of the dual-camera module by judging, measure and obtain the linear relationship between the linecount parameter value, the Again parameter value and the ambient brightness and the exposure value, and obtain the exposure linearity Proportional parameters k1, k2, and then according to the relationship between the two, adjust the exposure settings of the sub-camera to achieve exposure synchronization.

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. Contents of the invention [0004] The invention discloses a dual camera ...
