distances from reference coordinates with reference to a center of a display range on the display panel;

a conversion unit configured to convert the plurality of touch detected coordinates each corresponding to a different one
of the plurality of target touch marks into converted coordinates on the display panel using predetermined conversion coefficients,
each converted coordinate corresponding to a different one of the plurality of target touch marks;

a calculation unit configured to calculate for each of the display coordinates of the plurality of touch marks a difference
between the display coordinate of that target touch mark and the converted coordinate corresponding to the same touch mark;

a correction unit configured to calculate an average value with reference to the center of the display range from at least
a plurality of the differences calculated by the calculation unit, and to correct, using the average value, each of the converted
coordinates to generate for each converted coordinate a corrected coordinate so that distances between the reference coordinates
and the corrected coordinates become equal to each other; and

an update unit configured to calculate using the corrected coordinates new conversion coefficients for the conversion unit,
and to update the new conversion coefficients as conversion coefficients to be used by the conversion unit in subsequent touch
position detection of the touch panel,

wherein the correction unit corrects the coordinates converted by the conversion unit, using an average value of differences
that are obtained by extending one or more differences satisfying a predetermined condition from the differences calculated
by the calculation unit, and

wherein the correction unit corrects the coordinates converted by the conversion unit, using an average value of differences
except for at least a maximum difference of the differences calculated by the calculation unit.
