Abstract
An area identifying device includes a projecting unit, an image capturing unit, a calculating unit, and an identifying unit. The projecting unit is configured to project a pattern so that the pattern performs a predetermined movement. The image capturing unit is configured to capture, in sequential order, multiple images of a projection area on which the pattern is projected, each image including a plurality of image areas. The calculating unit is configured to calculate an amount of change of pattern appearances for each image area in the multiple images. The identifying unit is configured to identify, as a reflective area, at least one image area having a different amount of change of the pattern appearances from a reference amount of change of the pattern appearances based on the predetermined movement, among the calculated amounts of change of the pattern appearances.
