Patent ID: 7528878

Claim:
A solid state image device with a photoelectric conversion unit having a plurality of pixels two-dimensionally arranged and a read out unit for sequentially reading out outputs of the photoelectric conversion unit, the solid state image device comprising: a frame memory having a plurality of memory elements; a recorder for recording a signal of each pixel of the photoelectric conversion unit into the plurality of memory elements of the frame memory; and a line memory unit and a horizontal scanning unit for reading out signals recorded in the frame memory, wherein each of the plurality of memory elements is configured with two sample hold circuits each connected in series via switches, with each sample hold circuit including a capacitor and an impedance conversion unit, and with the impedance conversion unit being configured with an operational amplifier, the photoelectric conversion unit and the frame memory are driven by at least a vertical scanning unit, each pixel of the photoelectric conversion unit corresponds one-to-one with each memory element of the frame memory, such that each memory element records an output of a corresponding pixel.
