Abstract: A method of calibrating an image sensor including a color filter array having a first-type array pattern, the method includes capturing a target using the image sensor to generate first image data, performing a white balance operation on the first image data to generate second image data, performing an inverse white balance operation on the second image data based on a second-type array pattern to generate third image data, the second-type array pattern being different from the first-type array pattern, and calibrating the image sensor based on the third image data.

Abstract: An image processing method of an image signal processor includes obtaining a first estimated image by interpolating signals output from first color pixels, among a plurality of unit pixels included in a pixel array, in a first direction, obtaining a second estimated image by interpolating signals output from the first color pixels in a second direction, intersecting the first direction, detecting a first artifact component in the first direction with respect to pixels included in the first estimated image, detecting a second artifact component in the second direction with respect to pixels included in the second estimated image, obtaining a first weight based on at least a portion of the first artifact component and the second artifact component, and generating a first output image from the first estimated image and the second estimated image using the first weight.
