Patent number: 11184595Abstract: This document describes techniques for color correction using a sensor to reduce color distortions of a camera under a display of a computing device. A correction module of the computing device may determine a color correction used to improve content captured by a camera utilizing, in part, a sensor (e.g., a camera, ambient light sensor, and so forth) positioned underneath the display. The sensor may detect ambient light over time that is modified as it travels through the display, producing color distortions. The sensor may also detect a composite light over time that includes calibration light emitted by the display and ambient light. The correction module may compare the ambient light and composite light to determine the color correction usable to improve both the content captured by the camera and a user experience.Type: GrantFiled: May 19, 2021Date of Patent: November 23, 2021Assignee: Google LLCInventors: YungSheng Chang, Yan-Jang Jiang, Yenyu Peng
