Abstract:
1. A coordinate determination apparatus which determines output coordinates corresponding to input coordinates, said coordinate determination apparatus comprising: an obtain and store unit configured to serially obtain coordinate information indicating the input coordinates and a time of input of the input coordinates, and store the coordinate information onto a recording medium; a time correlation specifying unit configured to specify, as a time correlation value, a correlation between a time of input indicated by first coordinate information and a time of input indicated by second coordinate information, the first and the second coordinate information being among pieces of coordinate information stored on the recording medium; a coordinate correlation specifying unit configured to specify, as a coordinate correlation value, a correlation between a set of input coordinates indicated by the second coordinate information and a set of input coordinates indicated by third coordinate information, the second and the third coordinate information being among the pieces of coordinate information; a coordinate mode selection unit configured to select, as a coordinate mode, one of a first coordinate mode and a second coordinate mode, based on the coordinate correlation value and the time correlation value; and a coordinate transform unit configured to transform the set of input coordinates indicated by the second coordinate information into a set of coordinates according to the coordinate mode selected by said coordinate mode selection unit, so as to determine the set of coordinates as the output coordinates, wherein said coordinate transform unit is configured to (i) transform the set of input coordinates indicated by the second coordinate information into a set of coordinates previously associated with the set of input coordinates, when the first coordinate mode is selected, and (ii) transform the set of input coordinates indicated by the second coordinate information into a set of coordinates corresponding to output coordinates already determined for another set of input coordinates, when the second coordinate mode is selected.
