    Abstract: Various implementations disclosed herein include devices, systems, and methods implemented by an electronic device with an imaging sensor including a plurality of pixels (e.g., a matrix of pixels) that each are capable of detecting illumination intensity or contrast change using at least one shared photosensor. In some implementations, the imaging sensor is capable of operating in a first illumination intensity detecting mode (e.g., in a frame-based camera mode) or in a second contrast change detecting mode (e.g., in an event camera mode). In some implementations, the first illumination intensity detecting mode and the second contrast change detecting mode are mutually exclusive. In some implementations, pixels at an imaging sensor include two transfer transistors (e.g., gates) where a first transfer transistor allows intensity detection, and a second transfer transistor allows contrast change detection.
