摘要： An imaging array having a plurality of pixel sensors connected to a bit line is disclosed. Each pixel sensor includes a first photodetector having a photodiode, a floating diffusion node, and an amplifier. The floating diffusion node is characterized by a parasitic photodiode and parasitic capacitance. The amplifier amplifies a voltage on the floating diffusion node to produce a signal on an amplifier output. The first photodetector also includes a bit line gate that connects the amplifier output to the bit line in response to a row select signal and a voltage dividing capacitor having a first terminal connected to the floating diffusion node and a second terminal connected to a drive source that switches a voltage on the second terminal between a drive potential different from ground and ground in response to a drive control signal.

摘要： This video system includes a camera system and a video converter. The camera system includes an image pickup unit that captures a subject and obtains a pixel signal thereof, and a first processing circuit that generates two video signals from the pixel signal while respectively carrying out mutually-different adjustments and transmits transmission information obtained by adding information related to the respective adjustments of the video signals to one of the video signals. The video converter extracts the information related to the respective adjustments of the video signals from the transmission information and includes a second processing circuit that generates, on a basis of these pieces of information related to the adjustments, a restoration pixel signal by inverse-transforming one of the video signals included in the transmission information, and also generates a video signal corresponding to the other one of the video signals by performing an adjustment for the other one of the video signals on this restoration pixel signal.

摘要： Imaging systems and methods are disclosed that use locally flat scenes to adjust image data. An imaging system includes an array of photodetectors configured to produce an array of intensity values corresponding to light intensity at the photodetectors. The imaging system can be configured to acquire a frame of intensity values, or an image frame, and analyze the image frame to determine if it is locally flat. If the image frame is locally flat, then that image data can be used to determine gradients present in the image frame. An offset mask can be determined from the image data and that offset mask can be used to adjust subsequently acquired image frames to reduce or remove gradients.

摘要： Presence or absence of a photon is accurately detected in an image sensor with a simple configuration. A pixel circuit generates as an input voltage a signal voltage by photoelectrically converting light when the light is incident, and generates as the input voltage a predetermined reset voltage when light is not incident. A capacitor retains the predetermined reset voltage as a retained voltage. An amplification comparator amplifies a voltage difference between the input voltage and the retained voltage. A detection comparator outputs a result of determining whether or not the amplified voltage difference is higher than a predetermined value, as a detection signal indicating detected presence or absence of light incidence.

摘要： An image sensor includes a substrate including a light-receiving region and a light-shielding region, a device isolation pattern in the substrate of the light-receiving region to define active pixels, and a device isolation region in the substrate of the light-shielding region to define reference pixels. An isolation technique of the device isolation pattern is different from that of the device isolation region.
