Abstract
A roll correction section (21) performs correction to an image captured by a camera (11). A region limiting section (15) limits image data of an image in an upper region of the image and outputs the image data and a roll amount detection section (13) detects, from the limited and output image data, a roll amount of the image. A roll correction section (21) performs correction based on the detected roll amount.
Claims1
An image capturing processing method comprising:
- a first step of capturing an image by a camera;
- a second step of detecting, in an upper region of the image captured in the first step, feature data of the image and calculating a correction amount from the feature data;
- and
- a third step of performing, based on the correction amount calculated in the second step, correction control of an optical system of the camera or correction of image data of the image,
- wherein the second step includes the steps of:
- extracting a perpendicular edge element in the upper region;
- detecting, as the feature data, a roll amount of the image based on the perpendicular edge element;
- and
- calculating a roll correction amount of the image based on the roll amount detected at two or more times,
- wherein the second step includes the steps of:
- detecting, in addition to the roll amount, a motion vector as the feature data in the upper region;
- and
- calculating a motion correction amount of the image based on the motion vector.
