PROBLEM TO BE SOLVED: To provide an area specification device capable of specifying a reflective area economically, a method and a program.SOLUTION: An area specification device includes a projection unit, an imaging unit, a calculation unit, and a specification unit. The projection unit projects a pattern so as to perform a prescribed action. The imaging unit images an area where the pattern is projected in chronological order to obtain a plurality of images. The calculation unit calculates the amount of variation in a pattern for each image area in the plurality of images. The specification unit specifies, as a reflective area, an image area whose amount of variation is different from a reference variation accompanying a prescribed action among the calculated plurality of amounts of variation. |
