发明名称 PROJECTION APPARATUS AND OPTICAL RANGING METHOD
摘要 Disclosed is a projection apparatus including: a video display control section 53 to project and display a video according to input video data; and a projection distance obtainment section 14 to irradiate to a projection plane where the video is projected with a laser and displayed by the video display control section 53, and to obtain a projection distance to the projection plane, wherein when the projection distance is obtained by the projection distance obtainment section 14, the video display control section 53 adjusts a display status of at least a first video area 66 corresponding to a laser ranging point 63 which is an area where the laser is irradiated to a display status for obtaining the projection distance so that the distance from the projection apparatus to the projection plane can be measured fast and with high accuracy.
