Assignee: APPLE INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A pixel comprising:
a photodetector circuit configured to generate, at a sample node, pixel data, wherein, in a first state, the pixel data provides a differential value of the intensity of incident illumination and, in a second state, the pixel data provides an absolute value of the intensity of the incident illumination;
an output node coupled to an external processing circuit via an external readout line shared among a plurality of pixels, the external processing circuit configured to output a stream of pixel events, each respective pixel event generated when a comparator of the external processing circuit obtains a sample of pixel data from a particular pixel via the external readout line that breaches a threshold value; and
a readout switch intervening between the photodetector circuit and the output node that is configured to isolate the sample node from the output node until a selection signal is received from a controller of the external processing circuit.
