Method, computing device and nonvolatile computer readable storage medium for processing white balance

A computing device for processing white balance, comprising:

• one or more processors;
• a memory;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including:
• an acquisition module, configured to acquire a first image frame with a face image at a first acquisition time point, and a second image frame without a face image at different at a second acquisition time point different from the first acquisition time point;
• a first processing module, configured to perform a white balance processing for the first image frame based on a first gain value configured to adjust a color of the face image in the first image frame to a skin color, and further configured to perform a white balance processing for the second image frame based on a second gain value different from the first gain value;
• a determination module, configured to determine a transitional gain value for a transitional image frame acquired between the first acquisition time point and the second acquisition time point, based on a transition strategy for transition between the first image frame and the second image frame;
• and
• a second processing module, configured to perform a white balance processing for the transitional image frame based on the transitional gain value.

A nonvolatile computer readable storage medium storing computer executable instructions configured to control a computing device to execute a method for processing white balance, the method comprising:

• acquiring a first image frame with a face image at a first acquisition time point and a second image frame without a face image at a second acquisition time point different from the first acquisition time point;
• performing a white balance processing for the first image frame based on a first gain value configured to adjust a color of the face image in the first image frame to a skin color;
• performing a white balance processing for the second image frame based on a second gain value different from the first gain value;
• determining a transitional gain value for a transitional image frame acquired between the first acquisition time point and the second acquisition time point, based on a transition strategy for transition between the first image frame and the second image frame;
• and
• performing a white balance processing for the transitional image frame based on the transitional gain value.
