Abstract: Imaging systems and techniques are described. An imaging system causes a display to display light according to a predefined pattern. The imaging system receives image data of a scene from an image sensor. The image data is captured using the image sensor while the display is configured to display the light according to the predefined pattern. The imaging system processes the image data to generate at least one image frame of the scene based on detection of the predefined pattern in the image data. The imaging system outputs the at least one image frame of the scene.

Abstract: Imaging systems and techniques are described. An imaging system can receive image data from an image sensor with different sets of photodetectors sensitive to different electromagnetic (EM) frequency domains. The imaging system determines, based on image data of a scene received from the image sensor, a first focus setting for focusing on the scene using the image sensor in the first domain. The imaging system determines, based on the first focus setting and a difference between respective characteristics of the first domain and a second domain, a second focus setting for focusing on the scene using the image sensor in the second domain. The imaging system causes the image sensor to capture a first image of the scene in the first domain according to the first focus setting, and to capture a second image of the scene in the second domain according to the second focus setting.
