Method and system for processing video images

A video processing apparatus operable to generate a disparity map for an image sequence displayable on a screen defining a screen plane, wherein the image sequence includes a stereoscopically viewable first object perceivable by a viewer on an image plane different to the screen plane, the stereoscopically viewable object comprising a first image viewable by a viewer's eye and a second image viewable by the viewer's other eye, the apparatus comprising:

• an edge pixel detector operable to perform a first edge pixel detection process on the first image frame to identify edges within the first image frame;
• an identifier operable to identify a feature pixel of the first image from the detected edges;
• a block generator operable to generate a block of pixels including the feature pixel,
• a block matcher operable to perform block matching on a search region of the second image using the block of pixels from the first image frame, wherein the block of pixels generated from the first frame is correlated against the search region;
• and
• a disparity map generator operable to generate a disparity map by identifying a relative displacement of the feature pixel of the first image frame from a corresponding feature pixel in the second image frame.
