Method, apparatus and system for detecting and reducing the effects of color fringing in digital video acquired by a camera

An apparatus for controlling a camera and reducing the effects of color fringing in digital video acquired by the camera, said digital video comprising a sequence of acquired RGB digital image frames, each digital image frame comprising image information stored within a red, green and blue channel, the apparatus being configured to:

• communicate, to the camera, instructions pertaining to the camera acquiring a first digital image frame using a first camera setting, including a first iris aperture size;
• communicate, to the camera, instructions pertaining to the camera acquiring a second digital image frame using a second camera setting, including a second iris aperture size,
• wherein the second aperture size is smaller than the first aperture size;
• compare the first and the second digital image frame, at least one specific color component of said red, green and blue color components thereof,
• wherein each of said red, green and blue color components correspond to image information stored within the red, green and blue channels, respectively,
• wherein the apparatus is further configured to:
• localize regions having a disproportional ratio in the specific color component between the first digital image frame and the second digital image frame;
• and
• reduce the color component in the localized regions for subsequently acquired digital image frames.
