摘要： A system for selectively modifying gating rate in a single photon avalanche diode (SPAD) is configurable to access first frame metadata associated with a first image frame. The first image frame is captured by performing a first plurality of gate operations to configure the SPAD array to enable photon detection over a frame capture time period. The first plurality of gate operations is performed at a first gating rate such that the first plurality of gate operations comprises a first quantity of gate operations performed over the frame capture time period. The system is further configurable to define a second gating rate based on the first frame metadata and capture a second image frame by performing a second plurality of gate operations to configure the SPAD array to enable photon detection at the second gating rate.

摘要： An image pickup apparatus includes an image sensor including a plurality of normal pixels and OB pixels obtained by dividing each pixel into n, and an image processing circuit. The image sensor can read each pixel row in a first read mode in which a pixel signal is generated and read or in a second read mode in which n signals relating to n divided pixel signals are read in n rows. The image processing circuit performs processing on signals read in the first and second read modes to generate image data and performs OB level correction processing on a normal pixel signal read from the normal pixels in the second read mode using an OB pixel signal read from the OB pixels in the first and second read modes.

摘要： To reduce a dark current of an image sensor including a photoelectric conversion unit disposed on a back surface of a semiconductor substrate.
The image sensor includes a photoelectric conversion unit, a through-electrode, a charge holding unit, a back-side high impurity concentration region, and a front-side high impurity concentration region. The photoelectric conversion unit is disposed on a back surface of a semiconductor substrate and performs photoelectric conversion of incident light. The through-electrode is formed in a shape penetrating from the back surface to a front surface of the semiconductor substrate and transmits a charge generated by the photoelectric conversion. The charge holding unit is disposed on the front surface of the semiconductor substrate and holds the transmitted charge. The back-side high impurity concentration region is disposed in a region adjacent to the through-electrode on the back surface of the semiconductor substrate and is formed to have a higher impurity concentration than an impurity concentration of a region adjacent to the through-electrode at the central portion of the semiconductor substrate. The front-side high impurity concentration region is disposed in a region adjacent to the through-electrode on the front surface of the semiconductor substrate and is formed to have a higher impurity concentration than the impurity concentration of the region adjacent to the through-electrode at the central portion of the semiconductor substrate.
