DYNAMIC REGION OF INTEREST AND FRAME RATE FOR EVENT BASED SENSOR AND IMAGING CAMERA

摘要

An imaging device with a plurality of image sensing pixels and a plurality of event detection pixels is provided. The image sensing and event detection pixels can be provided as part of different arrays of pixels, or can be included within a common array of pixels. The event detection pixels are operated continuously to provide signals indicating the occurrence of events. In response to detecting an event, image sensing pixels are selectively operated. The selective operation of the image sensing pixels can include activation of image sensing pixels within one or more regions of interest, while image sensing pixels not included in any region of interest remain off. The selective operation of the image sensing pixels can include the selection of a frame rate applied across an array of mage sensing pixels, or within determined regions of interest.
