Claim One:
1. A method comprising: providing a right image and a left image in circuitry, providing, in the circuitry, a disparity estimation map relating to both images, generating, using the circuitry, a left subtitle detection map for the left image and a right subtitle detection map for the right image, each map indicating subtitle areas within an image, for said subtitle areas and based on said disparity estimation map, determining, using the circuitry, a subtitle disparity value for X and Y directions common for all of the subtitle areas, evaluating, using the circuitry, a consistency between the left subtitle detection map and the right subtitle detection map by comparing image data of the subtitle areas in the right image to image data of the subtitle areas in the left image when the subtitle areas in the right image and the subtitle areas in the left image are shifted relative to each other by an amount determined by the subtitle disparity value for the X and Y directions; detecting, using the circuitry, false positives in generation of the left subtitle detection map and the right subtitle detection map in accordance with the consistency, and using said left and right subtitle maps and said subtitle X and Y disparity values in an image interpolation process, using the circuitry.
