Solid state image sensor with signal line potential adjustment circuit and method of driving the same |
摘要 |
A solid state image sensor includes an imaging circuit, a selection circuit, a signal line and an adjustment circuit. The imaging circuit has a plurality of unit cells including a photo-detection section and a first reference potential generating section which generates a first reference potential. The selection circuit selects the unit cell. The signal line is supplied with a signal potential corresponding to a signal charge from the unit cell in a read-out operation, and supplied with the first reference potential in a reset operation. The adjustment circuit operates in response to an adjustment instruction signal which is asserted in an adjustment operation following the reset operation, and applies a second reference potential to the signal line in accordance with a potential of the signal line.
