发明名称 MECHANICAL SHUTTER CONTROL METHOD AND IMAGE SENSING APPARATUS
摘要 A control method for a mechanical shutter in an image sensing apparatus that has the mechanical shutter which includes and a second curtain held in a pre-travel initial position using electric power, that performs image sensing using an image sensor, and that has an electronic viewfinder function. The voltage of the electric power for holding the second curtain is reduced during execution of the electronic viewfinder function, the voltage of the electric power for holding the second curtain is raised if a shutter speed set for image sensing is faster than a preset period in a case where still image sensing is instructed, and the second curtain is made to travel when a period corresponding to the shutter speed has elapsed.
