Abstract: In some aspects, the present disclosure provides a method for sharing a single optical sensor between multiple image processors. In some embodiments, the method includes receiving, at a control arbiter, a first desired configuration of a first one or more desired configurations for capturing an image frame by the optical sensor, the first one or more desired configurations communicated from a primary image processor. The method may also include receiving, at the control arbiter, a second desired configuration of a second one or more desired configurations for capturing the image frame by the optical sensor, the second one or more desired configurations communicated from a secondary image processor. The method may also include determining, by the control arbiter, an actual configuration for capturing the image frame by the optical sensor, the actual configuration based on the first desired configuration and the second desired configuration.

Abstract: Examples are described of automatic exposure timing synchronization. An imaging system includes a first image sensor configured to capture a first image according to a first exposure timing, including by exposing first region of interest (ROI) image data at the first image sensor for a first ROI exposure time period. Based on the first exposure timing, the imaging system sets a second exposure timing for a second image sensor to capture a second image. Capture of the second image according to the second exposure timing includes exposure of second ROI image data at the second image sensor for a second ROI exposure time period. The second exposure timing may be set so that the start of the second ROI exposure time period aligns with the start of the first ROI exposure time period, and/or so that the first and second ROI exposure time periods overlap.
