摘要：

To solve the problem of white balance inconsistency caused by hardware difference of multiple camera modules in multi-camera imaging systems, a white balance consistency conversion method was proposed based on illuminant estimation . The white balance decision point of the source camera was converted to the reference camera by decision point conversion, look-up table and classification decision point conversion method. What’s more, the algorithms were evaluated under various light sources by three indexes: white balance chromaticity ratio difference, white point color difference and full-color color difference. The results show that the proposed look-up table and classification decision point conversion method can effectively improve the white balance consistency of multi-camera modules, meet the requirements of mobile imaging system, and guide the module hardware design and selection of multi-camera imaging systems. © 2022 Beijing Institute of Technology.
