Patent ID: 8804004

Claim:
An imaging apparatus comprising: an imaging unit; a setting unit configured to select and set one of a plurality of commercial power frequencies; a frame rate setting unit configured to set a frame rate corresponding to the commercial power frequency set by the setting unit; a control unit configured to control the imaging unit such that imaging is carried out at the frame rate set by the frame rate setting unit to thereby acquire image data successively; a detection unit configured to detect a scanning line part at which luminance changes to differ between image data items successively acquired by the control unit; a changing unit configured to change the commercial power frequency set by the setting unit in accordance with a detection result obtained by the detection unit; an exposure diagram information storage unit configured to store a plurality of types of exposure diagram information items in each of which one period of a respective one of the commercial power frequencies is made a lowest shutter speed; and an exposure control unit configured to read exposure diagram information corresponding to the commercial power frequency set by the setting unit from the exposure diagram information storage unit, and control an exposure time of the imaging unit in accordance with the read exposure diagram information to thereby cause the imaging unit to acquire image data, wherein the control unit is configured to perform a change of control, from the control of the imaging unit carried out by the exposure control unit, to the control of the imaging unit in which imaging is carried out at the frame rate set by the frame rate setting unit, while acquiring image data successively.
