Abstract:
The present technology relates to signal processing device and method, an imaging element, and an electronic device capable of reducing a rise of costs. A signal processing device according to the present technology includes a measurement unit that performs measurement of a length of a period from an input start of a signal to a change of a value of the signal a plurality of times, retains measured values obtained by the measurement performed the plurality of times, sets an initial value of the measurement on the basis of any one of a plurality of the retained measured values, and performs the measurement by using the initial value. The present technology is applicable to an electronic circuit such as a flip-flop circuit and an A/D conversion unit, an imaging element such as a CMOS image sensor, and an electronic device such as a digital still camera, for example.

Claim (Index 34):
An image sensor, comprising:\n a pixel array; a column-parallel processing unit, including:\n a gray code counter; \n a plurality of column analog to digital (A/D) conversion units, wherein each of the column A/D conversion units includes:\n a higher bit binary counter; and \n a lower bit gray code latch, wherein a gray code clock signal generated by the gray code counter is supplied to the lower bit gray code latch, and wherein the lower bit gray code latch generates gray codes on the basis of the gray code clock signal and converts gray codes into binary codes to generate lower bits of a binary code that are supplied to the higher bit binary counter; \n \n a control unit, wherein the control unit supplies a control signal to the column-parallel processing unit.
