A circuit is used with an imager that is capable of capturing an image. The circuit includes a memory that is configured to during a first time interval, store a first representation of a first subimage of the image from the imager and during a second time interval, receive an update from the imager and use the update and the first representation to store a second representation of a second subimage of the image. The first subimage partially overlaps the second subimage, and the update represents a portion of the second subimage that is not present in the first subimage. The circuit also has an output circuit that is configured to during the first time interval, use the first representation to generate output signals representative of the first subimage and during the second time interval, use the second representation to generate output signals representative of the second subimage.
