摘要:
A method, apparatus, computer-readable storage medium, and terminal for calibrating automatic white balance is provided including: obtaining a first white point acquired by a device under calibration capturing a neutral color under a calibration light source, and obtaining a second white point acquired by a predetermined golden set capturing a neutral color under the calibration light source; if either or both a first difference value between a first red deviation value and a second red deviation value is greater than a first predetermined threshold value and a second difference value between a first blue deviation value and a second blue deviation value is greater than a second predetermined threshold value, performing one or more of adjusting the second red deviation value so that the first difference value becomes smaller and adjusting the second blue deviation value so that the second difference value becomes smaller; and calibrating the device under calibration by using one or more of the adjusted second red deviation value and the adjusted second blue deviation value as a first golden value and a second golden value, respectively.
