AUTOMATIC PHASE ADJUSTING APPARATUS

摘要

A digital imaging signal obtained by converting an image data obtained by an imaging element into a digital value by pixel is inputted to an automatic phase adjusting apparatus, and the automatic phase adjusting apparatus adjusts a pulse phase to be used for imaging, based on the digital imaging signal. The automatic phase adjusting apparatus is provided with a luminance level detecting section for calculating luminance of the digital imaging signal for a plurality of pixels in a first pixel region; a variance calculating section for calculating a variance value which indicates signal variance for each pixel of the digital imaging signal for a plurality of pixels in a second pixel region; and a timing adjusting section for adjusting the pulse phase, corresponding to the calculation results of the luminance level detecting section and the variance calculating section.
