Abstract:
The present disclosure relates to a method and a device for correcting a color temperature of a flash lamp in the field of the computer technology. The method includes: obtaining a first color temperature value of a gray point region in a first image, in which the first image is obtained by capturing a scene when the flash lamp is closed; searching for an image region corresponding to the gray point region in a second image, in which the second image is obtained by capturing the scene when the flash lamp is open; and correcting the color temperature for the light compensation of the flash lamp according to a difference obtained by subtracting the first color temperature value from the second color temperature value.
