<p>PROBLEM TO BE SOLVED: To let an observer easily know a suitable position by detecting the observer's position when the observer is to watch a device screen, calculating the suitable observer's position and instructing the position to the observer. SOLUTION: Longitudinal and lateral indicators 24 and 26 are composed of plural LEDs, and in order to facilitate confirmation, LEDs 24a and 26a showing the central proper position are enlarged. The longitudinal indicator 24 gets away from the proper position with move to the downside and shows too much approach to the upside. Besides, the indicator 26 shows the deviation from the proper position to right by turning on the right LED and shows deviation to left by turning on the left LED. When the observer comes in front of device, the face position of observer is detected by photographing the observer through cameras 20 and 22 of stereo camera functions. At such a time, the correspondent relation of areas is grasped based on area features among plural images photographed by the cameras 20 and 22, the three-dimensional position of area is specified through triangle measurement based on the correspondent area among the images, and movement can be instructed to the observer.</p> |
