摘要： In a capacitive load drive circuit, in order to bring an output terminal used for supplying a drive voltage to a non-selected capacitive load into a high impedance state and in order to prevent the capacitive load from being unnecessarily driven by electric charge flowing to parasitic diodes at the output terminal, such as to prevent a non-selected electroluminescence element from turning on, a synchronizing unit generates second selecting signals by synchronizing first selecting signals to a clock signal constituting a basis of a drive signal of a common inverter for generating drive voltage to a common output terminal of plural electroluminescence elements, a drive signal generating unit brings individual output terminals into the high impedance state based thereon and a timing thereof is synchronized to a timing at which a potential difference between two poles of the non-selected electroluminescence element is nullified.

A comparator compares a reference voltage with an input voltage, the reference voltage having a ramp waveform whose voltage value varies with time, a lower-bit storage element holds a count value in a predetermined count pattern, based on an output signal from the comparator, a Gray code binary conversion circuit converts the count value in the count pattern held by the lower-bit storage element into binary data, and a storing operation control circuit supplies a pulse signal corresponding to the binary data obtained by conversion in the Gray code binary conversion circuit to a lower-bit U/D CNT. The present technology is applicable to, for example, an image sensor storing a count value in a storage element with use of a Gray code or a phase shift code as a clock signal.
