Disclosed herein is an electronic camera for generating an image having a
wide dynamic range by synthesizing two image pickup signals of different
exposure amount generated by using an electronic shutter function and
means for shutting off light, shading of image pickup signals resulting
from difference in charge accumulating time among the pixels of image
pickup device due to operation from opened state to closed state of the
means for shutting off light being corrected by a shading correction means
to form a synthesized image without an occurrence of false color due to
shading. Also provided is an electronic camera generating two image pickup
signals of different exposure amount by two shots of picture taking each
using a flash emission in combination, at least one of an electronic
shutter of image pickup device and means for shutting off light, as well
as an emission of the flash emission means, being controlled to equalize
between the two shots of picture taking ratio of exposure by normal light
excluding light from the flash emission means and ratio of emission amount
by the light from the flash emission means so that the two image pickup
signals can be readily generated as having a predetermined exposure amount
ratio in every part of a frame of picture even when a flash emission is
used in combination.
