In a solid state image sensor having a pixel array, a first frame is imaged using varying exposure times in a series of zones. The exposure time for a subsequent frame is selected from the results of the first frame, The exposure times are controlled in a rolling blade manner by controlling the number of lines between reset and readout. The sensor is particularly suited to use in bar code readers.

A semiconductor device includes a semiconductor substrate, a photon avalanche detector in the semiconductor substrate. The photon avalanche detector includes an anode of a first conductivity type and a cathode of a second conductivity type. A guard ring is in the semiconductor substrate and at least partially surrounds the photon avalanche detector. A passivation layer of the first conductivity type is in contact with the guard ring to reduce an electric field at an edge of the photon avalanche detector.

A CMOS single photon avalanche diode (SPAD) design uses conventional, or at least known, CMOS processes to produce a device having a breakdown region in which the main p-n junction is formed of a deep n-well layer, and optionally on the other side, a p-add layer. The SPAD may also have a guard ring region which comprises the p-epi layer without any implant. The SPAD may have curved or circular perimeters. A CMOS chip comprises SPADs as described and other NMOS devices all sharing the same deep n-well.

A proximity-based awareness system that includes a mobile computing device for each user and a system server in communication with the mobile devices. The system server may enable the user to create and edit a personal profile; broadcast the profile to another user; enable the user to search for and view another's personal profile and an event profile; bookmark an interesting event and an interesting user based on keywords; store a profile image or profile video associated with the user, and designate a virtual presence at a location. Each mobile device includes a processor that may determine the location of the user; provide an interface to enable the user to interact with the system server, transmit information to the system server, and display information received from the system server; and allow the user to enter keywords. As such, the system allows users to become aware of other nearby users.

An image sensor IC may have a non-volatile memory for several functions. The functions may include storing control parameters for a camera autofocus module, part tracking data, and data for defect correction or color science. The non-volatile memory can in particular be an antifuse non-volatile memory, which may not need special light shielding.

A photodetector includes a photodiode and output circuitry coupled to the photodiode. The photodetector is configurable for operation in at least two modes. A first configurable mode operates the photodetector as an integrating sensor. In this first mode, a bias voltage across the photodiode is set below the breakdown voltage of the photodiode and the output circuitry is configured to read an analog integration output voltage from the photodiode. A second configurable mode operates the photodetector as a single photon avalanche detector. In this second mode, the bias voltage across the photodiode is set above the breakdown voltage of the photodiode and the output circuitry is configured to read an avalanche output voltage.
