Patent ID: 8398317

Claim:
An imaging apparatus, comprising: an image sensor that performs an electronic shutter function; a mechanical shutter including a first curtain and a second curtain, which controls light incident on the image sensor; and a controller that calculates a moving characteristic of the mechanical shutter based on an amount of electric charge accumulated in a first area of the image sensor and an amount of electric charge accumulated in a second area of the image sensor, while the mechanical shutter is moving, and controls the electronic shutter function of the image sensor based on the calculated moving characteristic of the mechanical shutter, wherein the controller detects the amounts of electric charges accumulated in the first area and the second area at least two times at different locations while the mechanical shutter is moving, and calculates the moving characteristic of the mechanical shutter by inversely calculating a ratio of the amount of electric charge accumulated in the second area to the amount of electric charge accumulated in the first area for each location.
