Abstract
Disclosed herein is a mobile communication terminal equipped with a camera having an image distortion compensation function which compensates image distortion created by a luminance difference between pixels in the vicinity of a central portion of a pixel array of an image sensor and pixels in the vicinity of an outer portion of a pixel array of the image sensor by detecting a Y-component value of the central pixel of the pixel array of the image sensor and Y-component values of the pixels located diagonally to the central pixel, comparing the Y-component value of the central pixel with the Y-component values of the pixels located diagonally to the central pixel, generating compensation values for compensating signal distortion in each of the pixels located diagonally to the central pixel according to the comparison result, and outputting a distortion compensation command, together with the compensation values, to the ISP (image signal processor).
