In one implementation, an event sensor includes a plurality of pixels and an event compiler. The plurality of pixels are positioned to receive light from a scene disposed within a field of view of the event sensor. Each pixel is configured to have an operational state that is modified by control signals generated by a respective state circuit. The event compiler is configured to output a stream of pixel events. Each respective pixel event corresponds to a breach of a comparator threshold related to an intensity of incident illumination. Each control signal is generated based on feedback information that is received from an image pipeline configured to consume image data derived from the stream of pixel events.

Various implementations disclosed herein include devices, systems, and methods implemented by an electronic device with an imaging sensor that includes both an arrangement of first pixels and a plurality of second pixels at or near the perimeter (e.g., in a surrounding rectangle) of the arrangement. In some implementations, the second pixels, which may be larger in size than the arrangement of first pixels, can be intermittently positioned, for example, with intervening space in between groups of one or more second pixels along the side columns, top rows, or bottom rows of the arrangement. In some implementations, detected movement in a physical environment is determined to correspond to a person approaching the electronic device based on data of the second pixels. In some implementations, detecting the person approaching the electronic device initiates a user verification process at the electronic device.

Techniques are described for luminance-adaptive processing of hexa-deca red-green-blue-white (RGBW) color filter arrays (CFAs) in digital imaging systems.
