Abstract

PURPOSE: To facilitate the handling of handwriting information by inputting image information and performing display corresponding to the input on the same surface.
CONSTITUTION: A light pen 11 for writing characters, etc., on a display surface 12 serving as an input surface generates, for example, infrared rays differing in wavelength from the display light of the display surface 12. Then, an image sensor 16 is arranged corresponding to the pen 11 on the display surface 12 in such a way that a lens 13, a half-mirror 14 and a color filter 15 are interposed, thus constituting an input part. On the other hand, a light bulb 21 is arranged, corresponding to a light source 17, with a lens 19, the half-mirror 14 and a polarizer 20 interposed, and a display surface 12 is arranged, corresponding to the light bulb 21, with the polarizer 20, the half-mirror 14, and the lens 13 interposed, thus constituting a display part. Then, a picture information controller 22 is connected to the image sensor 16 and light bulb 21.
