Patent ID: 7894718

Claim:
An imaging apparatus comprising: an image sensor configured to capture an image of an object; a mechanical shutter including a curtain and a curtain holding mechanism configured to electromagnetically hold the curtain at an initial position prior to a travel; a time measurement unit configured to measure an energization time for energizing the curtain holding mechanism and an elapsed time between stoppage of energization to the curtain holding mechanism and restart of energization to the curtain holding mechanism; an adjustment unit configured to adjust time which is between a point starting an exposure of the image sensor and until releasing a power distribution to the curtain holding mechanism, if a difference value between the energization time and the elapsed time is greater than a predetermined threshold, wherein the time is based on a brightness of the object; and an exposure control unit configured to perform exposure control for the image sensor based on the time adjusted by the adjustment unit if the difference value is greater than the predetermined threshold.
