Phase adjusting device and digital camera

摘要

The timing adjustment unit gives a phase adjustment instruction of the pulse to the imaging device so as to converge to an optimum phase of the pulse set based on the calculation results of the luminance level detecting unit and the variance calculating unit. Furthermore, the timing adjustment unit controls the imaging device so that an exposure state of the analog imaged signal is suited for a luminance level detection process by the luminance level detecting unit and the variance calculation process by the variance calculating unit.
