摘要： Embodiments of the invention disclose a video imaging system. The system comprises a mechanism to operate in a first capture mode capture a first image sequence comprising images taken at a first exposure and at a first frame rate; a mechanism to perform a detecting operation to detect clipping in said first image sequence a mechanism to selectively switch to operating the video imaging system in a second capture mode to capture at least one additional image sequence comprising images taken at a different exposure, if clipping is detected; and a mechanism to perform a merging operation to merge the image sequences to produce high-dynamic range video.

摘要： A method for auto-exposure control in a multi-imager system is disclosed. The method comprises using an auto exposure control circuit of a first imager to set exposure control parameters based on a target brightness; and selectively adjusting the target brightness based on difference in brightness between the images from the first imager and images from other imagers in the system.
