An event-based vision sensor comprises an array of pixel circuits (60), each configured to produce a respective photocurrent, wherein the array of pixel circuits is divided into one or more clusters (120) of multiple pixel circuits; and a cluster control circuit (102, 104) configured, for each cluster, to generate (...

A merged frame-based and event-based image sensor pixel is provided, comprising a reverse-biased photodiode (PD); a frame-based signal readout circuit (FBRD) connected to a cathode of the photodiode; and an event-based signal readout circuit (EBRD) connected to an anode of the photodiode. Light received in the photo...

An event-based vision sensor, comprises an array (10) of event-based pixels, each pixel configured to record events based on variations of a sensed photocurrent and enable, at the occurrence of an event, a request line common to pixels aligned along an axis of the array; a request arbiter (12, 20) configured to resp...

A method for detecting a pupil of an eye with an event-based vision sensor, com-prises the steps of directing a first light source (12) towards the eye (10); observ-ing the eye with the event-based sensor (14); and intermittently submitting the sensor to a uniform background signal (16). (Figs. 2A, 2B) ...

ABSTRACT “TRANSMISSION OF AN EVENT STREAM THROUGH A MIPI CAMERA SERIAL INTERFACE” A method for transmitting an event stream produced by an event-based vision sensor (10) over an interface (14, 16) configured to transmit data in successive packets (H-CS) grouped in successive frames (FS-FE) comprises the steps of a...

An image enhancement method using multi-frame stacking comprises the steps of storing multiple frames of a target scene captured by a frame-based camera (10) during an acquisition interval (Tacq); storing a series of events produced during the acquisition interval by an event-based camera (12) viewing the target sce...
