Abstract:
1. An electronic camera comprising: a single image pickup device having an electronic shutter function capable of desirably controlling exposure amount by controlling charge accumulating time; and unit for shutting off light from a light receiving surface of the image pickup device; and image pickup signal of smaller exposure amount generated by using the electronic shutter function of said image pickup device; image pickup signal of larger exposure amount thereafter generated by controlling charge accumulating time of the image pickup device by the unit for shutting off light; the two image pickup signals synthesized to obtain an image having an increased wide dynamic range; said unit for shutting off light comprising a focal-plane shutter, shutter charge of the focal-plane shutter effected immediately after a completion of electronic shutter's operation of said image pickup device in the state where charge accumulating operation of the image pickup device being halted, and charge accumulating operation of the image pickup device started after completion of the shutter charge so as to effect control of a charge accumulating time by a normal focal-plane shutter operation.
