PROJECTION APPARATUS AND PROJECTION METHOD

摘要

A projection apparatus includes: a position detecting unit that detects a position of a pointer indicated by a pointing device on a projection surface; a calculating unit that calculates a characteristic value that represents characteristics of move of the pointer from positions detected by the position detecting unit in a predetermined period; a determining unit that determines whether or not the calculated characteristic value is equal to or greater than a predetermined threshold value; and an image generating unit that, when the characteristic value is determined to be smaller than the predetermined threshold value, generates an image to be projected by enlarging a region containing and surrounding the pointer.
