Abstract:
1. A solid state image sensor comprising: a light-receiving unit for converting incident light into a signal charge; a vertical register for transferring in a first direction a signal charge from the light-receiving unit; and a horizontal register for transferring in a second direction that differs from the first direction a signal charge transferred by the vertical register; wherein the solid state image sensor further comprises: a horizontal drive circuit for generating a horizontal drive pulse for driving the horizontal register; a dummy load; a pseudo-horizontal drive circuit for generating a pseudo-horizontal drive pulse successive to the horizontal drive pulse, the pseudo-horizontal drive pulse having a same pulse repetition period as the horizontal drive pulse, and for driving the dummy load during an interval in which the horizontal drive pulse is suspended; and a power supply unit for connecting to the horizontal drive circuit and the pseudo-horizontal drive circuit.
