    摘要： The present invention relates to a solid-state image pickup device, a driving control method, and an image pickup apparatus that are capable of performing, in the case of changing the resolution of AD conversion, changing of only a pulse that needs to be changed, with a more simplified configuration.
    In a case where the mode of the resolution of AD conversion is a 9-bit mode, a decoder 102 operates only an H counter 104. In a case where the mode of the resolution of AD conversion is a 10-bit mode or a 12-bit mode, the decoder 102 stops a counting operation by the H counter 104 and starts counting by an idle counter 106 when the count value of the H counter 104 reaches a start count value stored in a register 101, and resumes counting by the H counter 104 when the count value of the idle counter 106 reaches the number of counts stored in the register 101. The present invention is applicable, for example, to an image sensor employing a column AD conversion method.

    摘要： The present technology relates to an A/D converter, a solid-state image pickup device and a method of driving the same, and an electronic apparatus which are capable of reducing power consumption while reducing a circuit size. 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.
