摘要： To improve a temporal resolution.An image-capturing device includes a pixel array unit and a control unit. The pixel array unit includes a plurality of pixels classified into two or more groups, wherein pixels which belong to a same group are driven at a same timing. The control unit controls driving of the pixel array unit so that a number of groups in a period of time of read-out of electrical charge is a same number in any given timing in image-capturing operation, and that a number of groups in a period of time of exposure and accumulation of electrical charge is a same number in any given timing in the image-capturing operation.

摘要： The accuracy of a binary decision on a photon incident on a pixel is improved.An imaging device includes a generation unit and a decision unit. The generation unit generates a digital value indicating the amount of charge stored by photons incident on a pixel during an exposure period based on a signal output by the pixel. The decision unit compares a threshold value set for each pixel having similar conversion efficiency at the time of conversion of the amount of charge stored in the pixel into a digital value generated by the generation unit, with the generated digital value, and makes a decision on the entrance of a photon into the pixel that output the signal.

摘要： A radiation counting device is provided that includes a scintillator, a pixel circuit, and an analog-to-digital conversion circuit. In the radiation counting device, the scintillator generates a photon when radiation is incident. In the radiation counting device, the pixel circuit converts the photon into charge, stores the charge over a predetermined period, and generates an analog voltage in accordance with the amount of stored charge. In the radiation counting device, the analog-to-digital conversion circuit converts the analog voltage into a digital signal in a predetermined quantization unit less than the analog voltage generated from the one photon.

摘要： An imaging apparatus with logarithmic characteristics includes: a photodiode that receives light; a well tap unit that fixes the potential of an N-type region of the photodiode; and a resetting unit that resets the photodiode, a P-type region of the photodiode outputting a voltage signal equivalent to a photocurrent subjected to logarithmic compression. The first potential to be supplied to the well tap unit is made lower than the second potential to be supplied to the resetting unit, so that the capacitance formed with the PN junction of the photodiode is charged when the resetting unit performs a reset operation. The present technology can be applied to unit pixels having logarithmic characteristics.
