The present invention enables prevention of influence of a trigger pulse
in an image from an image pickup apparatus, with a simple structure and
irrespective of exposure time and the cycle of the trigger pulse. The
present invention provides an image pickup apparatus having a CCD image
sensor 202 in which electric charges obtained by photoelectric conversion
of incident light from an object are stored, the stored electric charges
are swept away when a shutter pulse SUB is supplied, and after a read-out
pulse SG is supplied, an image pickup signal based on the stored electric
charges is read out synchronously with a horizontal synchronizing signal
HD, and the image pickup apparatus comprises a timing generator 212 for
generating the read-out pulse during a blanking period of the horizontal
synchronizing signal, first shutter pulse generation means 310 for
generating a first shutter pulse sub1 during every horizontal blanking
period of the horizontal synchronizing signal except for a period from
generation of a trigger pulse TRIG until generation of the read-out
pulse, second shutter pulse generation means 320 for generating a second
shutter pulse sub2 at the timing of the trigger pulse, and a switch 330
for selecting either the first shutter pulse sub1 or the second shutter
pulse sub2.
