Patent number: 12154480Abstract: A light emitter that operates through a display may cause display artifacts, even when the light emitter operates using non-visible wavelengths. Display artifacts caused by a light emitter that operates through a display may be referred to as emitter artifacts. To mitigate emitter artifacts, operating conditions for a display frame may be used to determine an optimal firing time for the light emitter during that display frame. The operating conditions used to determine the optimal firing time may include emitter operating conditions, display content statistics, display brightness, temperature, and refresh rate. Operating conditions from one or more previous frames may be stored in a frame buffer and may be used to help determine the optimal firing time for the light emitter during a display frame. Pixel values for the display may be modified to mitigate emitter artifacts.Type: GrantFiled: March 15, 2023Date of Patent: November 26, 2024Assignee: Apple Inc.Inventors: Jenny Hu, Chaohao Wang, Christopher E Glazowski, Clint M Perlaki, David R Manly, Feng Wen, Graeme M Williams, Hei Kam, Hyun H Boo, Kevin J Choboter, Kyounghwan Kim, Lu Yan, Mahesh B Chappalli, Mark T Winkler, Na Zhu, Peter F Holland, Tong Chen, Warren S Rieutort-Louis, Wenrui Cai, Ximeng Guan, Yingying Tang, Yuchi Che
