Solid-state image sensor and image sensing system |
摘要 |
A sensor has an image sensing unit including pixel blocks, and a readout unit for reading out a signal from the image sensing unit. The pixel block includes a photoelectric converter, first and second transistors, and a current source. First main electrodes of the first and second transistors are connected to a common node, and the current source is provided between the common node and a predetermined voltage. A signal readout operation includes an operation in which a voltage corresponding to charges in the photoelectric converter is supplied to a control electrode of the first transistor, and a temporally changing reference voltage is supplied to a control electrode of the second transistor. The readout unit reads out a signal from the image sensing unit via a second main electrode of the first transistor. |
