Patent ID: 7936387

Claim:
A phase adjustment device comprising: an intended-usage judger for judging an intended usage of an inputted digital imaging signal; a selector for selecting one or a plurality of signals to be inspected from a group of signals constituting the digital imaging signal based on a result of the judgment by the intended-usage judger; a phase adjuster for adjusting a phase of a pulse used when the digital imaging signal is picked up based on an output state of the signal to be inspected, and a sampling method judger for calculating a cycle and a phase adjustment amount of the sampling as criteria of the phase adjustment based on an image size, a frame rate and a resolution necessary for the usage judged by the intended-usage judger, wherein the digital imaging signal is generated based on an analog imaging signal outputted from an imaging element, and the pulse includes a peak sample pulse for detecting a peak level of the analog imaging signal, a reference sample pulse for detecting a signal level used as a reference when the analog imaging signal is subjected to correlated double sampling, and an AD clock signal necessary for AD-converting the analog imaging signal into the digital imaging signal.
