Abstract:
1. A coordinate input apparatus with region recognition, which calculates a pointed position by a pointer on a coordinate input region, comprising: calculation means for detecting the pointed position and calculating coordinates of the pointed position; region determination means for determining whether the coordinates calculated by said calculation means belong to a first region or a second region; pen-down state determination means for determining whether an input state of the pointer is a pen-down state where the pointer is touching the coordinate input region; setting means for setting pen-down information when said pen-down state determination means determines that the input state of the pointer is in said pen-down state, while setting pen-up information when said pen-down state determination means determines that the input state of the pointer is not in said pen-down state; and output means outputting the coordinates which belong to the first region and outputting the pen-down information regardless of the determination by said pen-down state determination means when said region determination means determines that the coordinates calculated by said calculation determination means belong to the first region, and outputting the coordinates which belong to the second region and outputting pen-down information or pen-up information set by said setting means on the basis of a determination result of said pen-down state determination means when said region determination means determines that the coordinates calculated by said calculation means belong to the second region.
