Patent ID: 8093934

Claim:
A solid-state image pickup element comprising: a pixel section in which a plurality of pixels that perform photoelectric conversion are disposed in a matrix form; a pixel read section having a function of reading analog pixel signals from the pixel section, and of converting the read analog pixel signals into digital signals; and a timing adjustment circuit configured to be capable of adjusting delay timing of the digital signals that are obtained by the pixel read section, the timing adjustment circuit including at least one data line on which digital data that is obtained by the pixel read selection is transmitted, a phase synchronization circuit that includes a plurality of oscillation delay elements which oscillate an oscillation signal, and that is configured to oscillate the oscillation signal by synchronizing a phase of a feedback clock with a phase of a reference clock, at least one delay circuit that includes a delay element which is disposed on the data line and which is equivalent to one of the plurality of oscillation delay elements, and that is configured to delay data which is to be transmitted on the data line, and a delay adjustment unit configured to adjust an amount of delay of the delay element of the delay circuit in accordance with a signal associated with oscillation of the phase synchronization circuit.
