Abstract
An image processing device that rotates an image according to the inclination of a line segment included in the image, includes an evaluation unit 106 that evaluates a plurality of line segments whose inclinations are different, on the basis of each of a plurality of different decision standards, and a selection unit 106 that selects, on the basis of the results of the plurality of evaluations, from among the plurality of line segments, a line segment on the basis of which the image is to be rotated.
Claims16
An image processing device that rotates an image according to an inclination of a line segment included in the image, comprising:
- an evaluation unit that evaluates a plurality of line segments whose inclinations are different, on a basis of each of a plurality of different decision standards;
- and
- a selection unit that selects, on the basis of the results of the plurality of evaluations, from among the plurality of line segments, a line segment on the basis of which the image is to be rotated, wherein
- the evaluation unit evaluates each of the line segments higher, the closer the line segment is to a center of the image.
An image processing method for rotating an image in correspondence to an inclination of a line included in the image, comprising:
- an evaluating step of evaluating a plurality of line segments each of which inclination angle is different, on a basis of a plurality of different decision standards;
- and
- a selecting step of selecting, on the basis of the results of the plurality of evaluations, from among the plurality of line segments, a line segment on the basis of which the image is to be rotated, wherein
- in the evaluating step, a line segment that is closer to a center of the image is evaluated higher.
An image processing device that rotates an image according to an inclination of a line segment included in the image, comprising:
- an evaluation unit that evaluates a plurality of line segments whose inclinations are different, on a basis of each of a plurality of different decision standards;
- and
- a selection unit that selects, on the basis of the results of the plurality of evaluations, from among the plurality of line segments, a line segment on the basis of which the image is to be rotated, wherein
- the evaluation unit evaluates each of the line segments higher, the closer the line segment is to a barycenter of a focusing area.
