Abstract
Disclosed are a white balance coefficient correction method and an electronic device. A look-up table is recorded. The look-up table includes a target color temperature and multiple corresponding first white balance coefficients, and multiple offset color temperatures and multiple corresponding second white balance coefficients. An actual color temperature based on the target color temperature in a correction environment is obtained. An automatic white balance correction operation is performed in the correction environment using the first image sensor to obtain multiple original white balance coefficients. One of the offset color temperatures in the look-up table is obtained according to the actual color temperature in response to the actual color temperature meeting an offset condition. The original white balance coefficients are corrected according to a difference between the second white balance coefficients corresponding to the one of the offset color temperatures and the first white balance coefficients.
