Title:
SOLID-STATE IMAGE PICKUP APPARATUS
Document Type and Number:
WIPO Patent Application WO/2008/007726
Kind Code:
A1
Abstract:
A solid-state image pickup apparatus capable of preventing image degradations, such
as shading, ringing and so on, from occurring in an image portion along the left
edge of a screen. The solid-state image pickup apparatus includes, in addition to
a horizontal drive circuit that generates a horizontal drive pulse for driving a
horizontal register, a pseudo horizontal drive circuit that generates a pseudo horizontal
drive pulse following the horizontal drive pulse during a horizontal blanking
interval. The horizontal drive circuit and pseudo horizontal drive circuit
are connected to a horizontal driver power supply part, which generates, during
the horizontal blanking interval, a current that is equal to a current generated
by the horizontal driver power supply part during an effective interval. This
arrangement can prevent any power supply ripples from occurring immediately after
the beginning of the effective interval.
