Abstract: One or more control signals in specified output states are generated at one time at a predetermined timing. A command generation section generates control data, piece by piece at each predetermined timing, corresponding to the plural control signals. A register sequentially receives the generated control data at the each predetermined timing and outputs one or more pieces of the control data to a command execution section at one time at a timing predetermined for the one or more pieces of the control data. The command execution section generates, at one time, one or more control signals of a value or values corresponding to the one or more pieces of the control data received from the register at one time at a timing predetermined for the one or more pieces of the control data.

Abstract: An imaging apparatus using a CCD image sensor in which a size of a circuit for generating a voltage to be applied to a substrate of the CCD image sensor is reduced. A partial range within a voltage range from a supply voltage Vcc to 0 V is divided by a resistance voltage divider and one of different voltage values obtained as a result of voltage division is selected by a selector according to external data and outputted to a high voltage amplifier. The high voltage amplifier generates a voltage signal with a voltage expressed by VMSUB=(Vdaout?Vdd2)×(3R+R)/R+Vdd2=4×Vdaout?3×Vdd2(V) to make it a middle voltage for an exposure control signal.

Abstract: The objective is to provide a sampling/holding circuit that can operate at high speed and low power consumption. The sampling/holding circuit has multiple sampling units 2-1˜k. Each sampling unit has input terminals 1-1˜k and output terminals 3-1˜k. The values received at the input terminals are sampled, and the sample values are accumulated. Also, the accumulated sample values are generated at output terminals 3-1˜k. One holding unit 6 has an input terminal 5 and an output terminal 7, which are shared by the multiple sampling units. By multiplexing the outputs of the multiple sampling units, multiplexing unit 4 connects any output to the input of holding unit 6. Holding unit 6 holds the sample value and generates it at output 7.
