Apparatus and methods for accurately sensing locations on a surface
First Claim
Patent Images
1. Apparatus for sensing an indication of a location on a surface at a first resolution using a video camera with a second resolution which is less than said first resolution, the apparatus comprising:
- a large vicinity generator operative to provide an indication of a vicinity of the location which is large in comparison to the second resolution; and
a large vicinity processor operative to process the indication of the vicinity in order to find a central location therewithin at a resolution which is at least equal to said first resolution, thereby to sense an indication of the location on the surface at a resolution which is at least equal to the first resolution.
