Title:
AUTOMATIC PHASE ADJUSTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2007/119483
Kind Code:
A1
Abstract:
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.
