Patent ID: 8646993

Claim:
An image pickup apparatus comprising: a shutter being switchable between a holding mode, in which a shutter spring is charged to hold a shutter drive member, a release mode, in which the shutter drive member that is held is released with the shutter spring being charged, and a travel end mode, in which the shutter drive member has traveled from the release mode using the shutter spring; a shutter drive motor configured to switch the shutter from the travel end mode to the holding mode and from the holding mode to the release mode; a mirror configured to switch between a mirror down mode, in which the mirror enters an imaging optical path, and a mirror up mode, in which the mirror flips out of the imaging optical path; a mirror drive motor configured to drive the mirror from the mirror down mode to the mirror up mode; a control unit configured to control the shutter drive motor so the shutter drive motor is switched between a drive mode, in which the shutter drive motor is driven, a first braking mode, in which the shutter drive motor is decelerated, a second braking mode, in which the shutter drive motor is decelerated more strongly than in the first braking mode, and an open mode, in which the shutter drive motor is idle; a first determination unit configured to determine whether the mirror drive motor is ready to drive the mirror from the mirror down mode to the mirror up mode; and a second determination unit configured to determine whether the shutter drive motor is to be switched from the first braking mode to the second braking mode, wherein if the first determination unit determines that the mirror drive motor is not ready to start driving the mirror to the mirror up mode after the shutter drive motor drives the shutter to the holding mode, the control unit switches the shutter drive motor to the first braking mode, and wherein if the first determination unit determines that the mirror drive motor is ready to start driving the mirror to the mirror up mode after the shutter drive motor is switched to the first braking mode and before the second determination unit determines that the shutter drive motor is to be switched to the second braking mode, the control unit switches the shutter drive motor to the open mode until a predetermined period of time has elapsed since the first determination unit determined that the mirror drive motor was ready to start driving the mirror to the mirror up mode.
