Abstract
In this exciting time of increasingly powerful computer tools only few imaginable things are left to be invented. Recently issued PC multimedia operating system Vista supports speech and hand writing recognition, visual and data streaming and networking, as well as traditional computer powers. Present invention is meant to fulfill the only gap left in computer abilities: which is comprehensive general purpose three-dimensional vision to enable computers to see the world they have changed so much. The main feature of this invention is an advanced and powerful image preprocessing method and apparatus supporting thereof.

15. A method for instant calculation of distances to objects by processing images received from an apparatus having two image sensors, each having an optical center and mounted in such a way that rows of their light sensing elements are parallel to a line connecting the optical centers, comprising the steps of:
-
obtaining images by the two sensors with overlapping view areas;
finding brightness step marks in the images;
determining the same marks in the corresponding rows of the light sensing elements of the image sensors;
calculating a shift between the same marks in the corresponding rows of the light sensing elements of the image sensors;
calculating distance to the object'"'"'s mark equal to the distance between the optical centers of the image sensors divided by the shift and multiplied by the focus.

16. A method for instant calculation of distances to objects by processing images received from an apparatus having two image sensors, each having an optical center and mounted in such a way that rows of their light sensing elements are parallel to a line connecting the optical centers, comprising the steps of:
-
obtaining images by the two sensors with overlapping view areas;
calculating a brightness step mark in a row of light sensing elements of one of the image sensors;
finding an identical brightness step mark in a corresponding row of the light sensing elements of the other image sensor;
calculating a positional difference between said brightness step marks in the corresponding rows of the light sensing elements of those image sensors;
assigning the distance value corresponding to said positional difference.
