    摘要: A telescopic differential operational amplifier circuit for use in a pipelined A/D converter is provided with two auxiliary differential amplifiers connected to two cascode circuits, each including cascode-connected first to fourth transistors. During the sampling phase, first and second switches are turned on to apply a predetermined bias voltage to the gates of first and fourth transistors, and the input terminal of the differential operational amplifier circuit is set to a common mode voltage. During the hold phase, the first and second switches are turned off so that a voltage of each of the gates of the first and fourth transistors change to follow an input signal inputted via the input terminal with coupling capacitors operating as a level shifter of the input signal. Then the differential operational amplifier circuit performs push-pull operation operative only in a transconductance drive region, and is prevented from operating in a slewing region.

With a first transistor turned on, the second detector outputs an electric charge stored in the capacitance in the second operation mode, and in the initialization mode a reset voltage set in the second data line is applied to the other end of the photo detecting element to initialize the photo detecting element.

    摘要: When successively reading out pixel information from an image region, where image pickup devices are arranged two-dimensionally, which is divided into a plurality of sub-regions, a readout unit inserts pixel information on pixels of interest in the respective sub-regions successively at predetermined intervals and reads them out. A control unit generates a frame from the pixel information, on pixels of interest inserted at the predetermined intervals, which has been read out from the readout unit. The control unit grasps a tendency of a picked-up image from the generated frame and performs a predetermined adaptive control according to the grasped tendency.
