METHOD FOR CORRECTING DISTORTION OF CAPTURED IMAGE, DEVICE FOR CORRECTING DISTORTION OF CAPTURED IMAGE, AND IMAGING DEVICE
First Claim
1. A method for correcting distortion of a captured image, the method comprising:
- receiving a detection output from a sensor that detects a change corresponding to a positional change of an imaging element in a horizontal direction and/or a vertical direction of a captured image at the time of imaging;
optically correcting distortion of a captured image in image data from the imaging element due to the positional change of the imaging element by controlling a control mechanism depending on the detection output received from the sensor in the detection output receiving step, the control mechanism being configured to control a position at which incident light from a target object enters the imaging element;
receiving image data resulting from the optical correction of a captured image in the correcting step from the imaging element, and detecting a motion vector per one screen of a captured image from the image data; and
further correcting distortion of a captured image due to the positional change of the imaging element for the image data from the imaging element based on the motion vector detected in the motion vector detecting step.
