Exposure timing control for multiple image sensors

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.
