METHOD APPARATUS AND SYSTEM FOR DETECTING AND REDUCING THE EFFECTS OF COLOR FRINGING IN DIGITAL VIDEO ACQUIRED BY A CAMERA

摘要

The present invention relates to a method, apparatus and system for detecting and reducing the effects of color bleeding in digital video obtained by a camera 210 comprising an aperture 212. The method comprises the steps of: (S102) obtaining a first digital image frame (110) by said camera (210) using a first camera setting comprising a first aperture opening size (104); Obtaining a second digital image frame 120 by the camera 210 using a second camera setting comprising a second aperture opening size 106 (S104), where the second opening size 106 is Less than the first opening size (104); Comparing (S106) the first 110 and second 120 digital image frames in at least a specific color component thereof; Localizing (S108) regions (130a, 130b) having non-uniform intensity ratios in the specific color component between the first digital image frame (110) and the second digital image frame (120); And reducing the specific color component in the localized regions 130a and 130b for a subsequently obtained digital image frame 140 (S110).
