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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2020-0019240 filed in the Korean Intellectual Property Office on February 17, 2020, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] Some example embodiments described herein relate to semiconductor devices, and more particularly, to image sensors capable of reducing calibration time, calibration methods of image sensors, and / or electronic devices for calibrating image sensors. Background technique [0004] An image sensor can generate image data of a target or a scene by capturing the target or scene. As the performance of mobile devices such as smartphones and smart tablets increases, image sensors are employed in the mobile devices. Image sensors that have been employed in mobile devices generate image data, and thus, image sensors can be used to create image-based content. [0005] The image...
