Patent ID: 7091465

Claim:
An image sensor having an image pickup part including an array of pixels to generate their respective charges in response to incidence of light, a readout part for outputting electric signals according to the charges generated in the respective pixels, a signal input electrode for inputting a clock signal to order transfer of the charge, into each of the pixels, and a bias voltage input electrode for inputting a bias voltage supplied to the image pickup part and to the readout part, said image sensor comprising: first voltage maintaining means connected to the signal input electrode and comprising a first voltage maintaining capacitor for maintaining a voltage of the signal input electrode, a terminal through which the clock signal is inputted and which is electrically connected to the signal input electrode, and an ac-signal blocking resistor connected between the first voltage maintaining capacitor and the terminal; and second voltage maintaining means connected to the bias voltage input electrode and comprising a second voltage maintaining capacitor for maintaining a voltage of the bias voltage input electrode.
