Title: IMAGE SENSOR AND IMAGE SENSOR DRIVING METHOD
Abstract:
An image sensor includes: a plurality of pixels arranged in a matrix manner and each having a photoelectric conversion element; a plurality of vertical signal lines to which the plurality of pixels are connected on a column-by-column basis; and a column signal processing circuit that is provided at each of the vertical signal lines and that performs signal processing by sampling picture signals and reset signals from the pixels via the vertical signal line. One end of the column signal processing circuit is connected to the vertical signal line, and the column signal processing circuit includes at least one capacitor holding the picture signals or the reset signals, a power source connected to one end of the capacitor and capable of applying a predetermined voltage, a first operation switch connected between the vertical signal line and the capacitor, and a second operation switch connected between the capacitor and the power source.
