According to an embodiment, 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 an area on which the pattern is projected, the image having a plurality of areas. The calculating unit is configured to calculate an amount of change of pattern appearances for each region in the multiple images. The identifying unit is configured to identify, as a reflective area, at least one 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 amounts of change of the pattern appearances that are calculated by the calculating unit. |
