A color separating/recombining unit used in liquid crystal projector using three reflection type liquid crystal panels. The color separating/recombining unit () has a cubic form comprising a light incidence surface () facing the light source unit (), three light incidence/output surfaces (), (), () respectively facing liquid crystal panels (), (), (), a light output surface () facing a projection optical system (), and another surface (). The color separating/recombining unit has thereinside a color separating/recombining means () that spectrally separates light shone from the light source () into three-primary-color components to allow them emit from corresponding light incidence/output surfaces (), (), () and to be reflected with their polarization directions rotated 90 degrees by the liquid crystal panels (), (), () disposed respectively facing the light incidence/output surfaces (), (), (), then recombines them, and emits them from the light output surface () to the projection optical system ().

A plurality of types of random dot pattern images each represented by data composed of a predetermined number of bits, one of which is one and the others of which are zero, and differing in the position of the bit which is one are overlapped, to produce one overlap image. A plurality of types of translation tables for obtaining an output image from the overlap image are successively switched, to successively output a plurality of types of images respectively corresponding to said random dot pattern images.

Method of and apparatus for producing moving image composed of random

A reference image and an index image are displayed on a three-dimensional display device with either one of the images taken as a left eye image and the other image taken as a right eye image. When a movement command to move a display position of the index image is inputted by a person to be inspected in order that a predetermined reference position of the reference image and the display position of the index image coincide with each other, the display position of the index image is moved on the basis of the movement command. The amount of deviation of the index image from the reference position of the reference image is calculated by the person to be inspected visually recognizing that the reference position of the reference image and the display position of the index image coincide with each other when confirmation input indicating that the person to be inspected visually recognizes the coincidence is provided by the person to be inspected.
