Abstract: Hybrid image sensors with on-chip image deblur (and associated systems, devices, and methods) are disclosed herein. In one embodiment, an image sensor includes (a) a plurality of CMOS image sensor (CIS) pixels configured to capture CIS data corresponding intensity of light incident on CIS pixels of the plurality of CIS pixels, (b) an event vision sensor (EVS) pixel configured to capture EVS data corresponding to events detected in light incident on the EVS pixel, and (c) a deblur circuit configured to generate deblurred image data based on the CIS data and an accumulation of events in the EVS data. The deblur circuit can be configured to compute the accumulation of events, such as using an event-based double integral model.

Abstract: A focus method and an image sensing apparatus are disclosed. The method includes capturing, by a plurality of event sensing pixels, event data of a targeted scene, wherein the event data indicates which pixels of the event sensing pixels have changes in light intensity, accumulating the event data for a predetermined time interval to obtain accumulated event data, determining whether a scene change occurs in the targeted scene according to the accumulated event data, obtaining one or more interest regions in the targeted scene according to the accumulated event data in response to the scene change, and providing at least one of the one or more interest regions for a focus operation. The image sensing apparatus comprises a plurality of image sensing pixels, a plurality of event sensing pixels, and a controller configured to perform said method.
