Title:
CONTOUR CORRECTION DEVICE AND IMAGE PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/091720
Kind Code:
A1
Abstract:
The present invention enables contour correction to be suitably executed even when an image contains an oblique line. A first correction unit (11) calculates a first correction amount for correcting contours in horizontal and vertical direct ions, and a second correction unit (12) calculates a second correction amount for correcting a contour in a direction orthogonal to an oblique line at a prescribed angle. A degree-of-obliqueness detection unit (13) detects a degree of obliqueness representing the extent to which the image approxima tes the oblique line at the prescribed angle. A signal correction unit (20) adjusts the first correction amount and the second correction amount according to the degree of obliqueness, and corrects a luminance signal by using the adjust ed correction amounts.
