The invention provides a white balance coefficient correction method and an electronic device. Recording a lookup table, wherein the lookup table comprises the target light source color temperature and a plurality of corresponding first white balance coefficients, and a plurality of offset light source color temperatures and a plurality of corresponding second white balance coefficients; and acquiring an actual light source color temperature based on the target light source color temperature in the correction environment. A first image sensor is used to perform an automatic white balance correction operation in a correction environment to obtain a plurality of original white balance coefficients. In response to the fact that the actual light source color temperature meets the offset condition, one of the offset light source color temperatures in the lookup table is obtained according to the actual light source color temperature; and correcting the original white balance coefficient according to the difference
