Method of determining color correction matrix, color correction method and electronic device

A color correction method comprising:

• receiving a first reference image generated by photographing a first object in a first lighting condition using a reference camera;
• receiving a first image generated by photographing the first object in the first lighting condition using a first camera;
• calculating a first color correction matrix of the first camera using the first reference image, the first image, and a first reference color correction matrix of the reference camera, the first color correction matrix and the first reference color correction matrix corresponding to the first lighting condition;
• receiving a first actual image generated by photographing a second object in the first lighting condition using the first camera;
• and
• correcting the first actual image using the first color correction matrix,
• wherein the first object is the same as or different from the second object.

A color correction method comprising:

• receiving a first reference image generated by photographing a first object in a first lighting condition using a reference camera;
• receiving a first image generated by photographing the first object in the first lighting condition using a first camera;
• calculating a first color correction matrix of the first camera using the first reference image, the first image, and a first reference color correction matrix of the reference camera, the first color correction matrix and the first reference color correction matrix corresponding to the first lighting condition, by determining the first color correction matrix such that a difference between the first image corrected using the first color correction matrix and the first reference image corrected using the first reference color correction matrix is minimized;
• receiving a first actual image generated by photographing a second object in the first lighting condition using the first camera;
• and
• correcting the first actual image using the first color correction matrix,
• wherein the first object is the same as or different from the second object.
