Abstract: Disclosed is a camera module which includes an image sensor including pixels outputting raw image data based on light incident from at least one of a display or the exterior, and control logic receiving the raw image data and generating image data. In a first operation mode, the control logic turns off calibration of the image sensor, receives first raw image data, which are based on the light incident from the display, from the image sensor, and generates crosstalk calibration data based on first output values included in the first raw image data. In a second operation mode, the control logic turns on the calibration of the image sensor, receives second raw image data, which are based on light incident from the display and the exterior, from the image sensor, and generates the image data based on second output values included in the second raw image data.

Abstract: An image evaluation method, including: obtaining a test image including a first lattice pattern formed by image edges; aligning the test image using the image edges to generate an aligned image including a second lattice pattern formed by aligned image edges; generating a compressed image by compressing the aligned image; and generating a quantified result by quantifying a per-pixel difference between the compressed image and the aligned image.
