Abstract: A plurality of pixel circuits are arranged in a row direction and a column direction. Each of the pixel circuits includes a photoelectric conversion circuit for light from a subject. Signal charge of the photoelectric conversion circuit is transferred to a charge holding circuit and is discharged via an overflow gate (OFG). A signal processing substrate includes a plurality of signal holding circuits for the plurality of pixel circuits. The signal holding circuit includes a holding capacity circuit that holds a voltage signal or signal charge transferred from the charge holding circuit. Driving for converting signals of the holding capacity circuit into digital signals in a row-sequential manner and outputting the digital signals is performed in a period of intermittent charge accumulation in which transfer and discharge of charge from the photoelectric conversion circuit to the charge holding circuit are alternately performed.

Abstract: An object of this invention is to correct the non uniformity between a plurality of image sensing regions in real time and cope with even dynamic variations such as temperature variations or variations over time. To achieve this object, a correction apparatus includes a plurality of level adjustment devices which independently adjust the levels of a plurality of image sensing signals output from a plurality of output terminals, an output level detection device which detects the output levels of the plurality of level adjustment devices, and a correction coefficient determination device which determines a correction coefficient for reducing the level difference between the image sensing signals on the basis of the detection result of the output level detection device.

Abstract: An image sensing apparatus includes a solid-state image sensing element having a plurality of pixels which output image sensing signals, a first determination device which determines whether a pixel of interest is a defective pixel candidate, by comparing the signal level of the pixel of interest subjected to defective pixel detection out of the plurality of pixels of the solid-state image sensing element, and the signal levels of a plurality of peripheral pixels around the pixel of interest, and a second determination device which, when the-first determination device determines that the pixel of interest is the defective pixel candidate, determines whether the determination result representing that the pixel of interest is the defective pixel candidate is erroneous detection, on the basis of the determination result of the first determination device representing whether a plurality of peripheral pixels around the pixel of interest are defective pixel candidates.
