Method controlling image sensor parameters

A method of controlling parameters of a plurality of image sensors, the method comprising:

• receiving a first image generated by a first image sensor in response to first parameters, and a second image generated by a second image sensor in response to second parameters;
• calculating first feature values related to the first image, and second feature values related to the second image;
• generating first comparison results by comparing the first feature values of fixed-size regions of the first image with the second feature values of fixed-size regions of the second image and comparing the first feature values of variable-size regions of the first image with the second feature values of variable-size regions of the second image, wherein the fixed-size regions are obtained by dividing a specific region for each of the first image and the second image equally according to a preset size and the variable-size regions are regions of different sizes contained in the specific region for each of the first image and the second image;
• controlling at least one parameter among the first parameters and the second parameters on a basis of the first comparison results;
• calculating third feature values related to the first image and fourth feature values related to the second image,
• wherein the generating of the first comparison results comprises generating second comparison results by comparing the third feature values of the first image with the fourth feature values of the second image.
