Scene lighting analysis using opposing smartphone cameras

A method for performing color correction, the method comprising:

• receiving a first image captured using a first camera included in an electronic device, wherein the first camera is oriented in a first direction with respect to the electronic device;
• receiving a second image captured by a second camera included in the electronic device, wherein the second camera is oriented in a second direction with respect to the electronic device, wherein the second direction is opposite to the first direction;
• calculating a color temperature based on the second image about ambient light that illuminates the first object;
• and
• performing color correction on the first image based on the calculated color temperature to obtain a color-corrected first image,
• wherein the first camera comprises a first image sensor having a plurality of first photodiodes and a first resolution, and
• wherein the second camera comprise a second image sensor having a plurality of second photodiodes and a second resolution less than the first resolution.

An electronic device, comprising:

• a first camera disposed at a first side of the electronic device;
• a second camera disposed at a second side of the electronic device, wherein the second side is opposite to the first side;
• and
• an image signal processor configured to:
• receive a first image captured by the first camera by capturing a first object;
• receive a second image captured by the second camera by capturing a second object;
• calculate a color temperature based on the second image about ambient light that illuminates the first object;
• and
• perform color correction on the first image based on the calculated color temperature to obtain a color-corrected first image.
