Imaging processing apparatus and method of imaging processing by controlling an imaging period

An imaging processing apparatus comprising:

• an imaging period controller configured, when driving an imager so as to image a subject with an exposure time less than a standard imaging period conforming to a certain video standard, to generate a frame of the standard imaging period every certain frames and to control an imaging period of the imager so that one of a preceding frame of the frame of the standard imaging period and a succeeding frame of the frame of the standard imaging period has an imaging period which is shorter than the standard imaging period and the other of them has an imaging period which is longer than the standard imaging period;
• a shutter controller configured to control reset timing of electric charges accumulated in the imager depending on an amount of light from the subject in accordance with the imaging period of the imager;
• a storage configured to store therein respective taken images imaged by the imager with the reset timing controlled;
• a phase corrector configured to detect a motion vector from a plurality of the taken images stored in the storage, to calculate a shift amount of the taken images relative to the standard imaging period, to generate frame interpolation images with respective pixels being shifted by the calculated shift amount in a direction corresponding to the detected motion vector, and to store the frame interpolation images in the storage;
• and
• a reading controller configured to read and output the respective taken images of the standard imaging period and the frame interpolation images stored in the storage with a reproduction speed corresponding to the standard imaging period.
