A 3D display device that includes: a first optical section of focal distance f1 provided with a group of small lenses arrayed along a specific direction; and a second optical section of focal distance f2 that converges N beams of parallel light that are emitted from the first optical section and hit the individual small lenses by converging so as to offset the N beams from an optical axis. A distance d1 between the first optical section and the second optical section satisfies f2&#x2212;f1&#x2266;d1&#x2266;f2 and a viewing distance d2 from the second optical section satisfies d2&#x2248;f2.

3D display device and method

A projector device includes an acquisition unit configured to acquire an image from an image pickup unit that picks up the image on a projection side of a transmissive type screen to which a display image is projected by a projector; a detection unit configured to detect a position where a luminance is changed on the acquired image; and an output unit configured to output the position on the acquired image where the change in luminance is detected.
