Title:
IMAGING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2007/119331
Kind Code:
A1
Abstract:
Troubles such as uneven exposure due to difference between the speeds of a front curtain
and a rear curtain or positional gap of curtain plane (vignetting) are restrained
while reducing power consumption. At the time of low speed shutter when the shutter
speed is set low by an exposure control means, exposure start operation is performed
by the electronic focal plane shutter function of an imaging element (the electronic
focal plane shutter is employed as the front curtain), and exposure end operation
is performed by a mechanical focal plane shutter. At the time of high speed shutter
when the shutter speed is set high by the exposure control means, both exposure
start operation and exposure end operation are performed by the mechanical focal
plane shutter (the mechanical focal plane shutter is employed as the rear curtain).
