Paper Abstract

A stereogram differs from the 3D picture often called stereo pair in appearance. There is no need of special viewer or glasses for stereopsis when viewing the sterograms. It is possible to intuitively carry out the intuitive estimation of depth perception by simultaneously viewing two pairs of stereograms which are arranged the upper and lower sides, or the right and left sides. In this study, modified digital color stereograms are directly viewed on the LCD screen or hard copy images by means of (a) crossing view method or (b) parallel view method. The apparent depth perception of stereograms can be effectively demonstrated by an adjustment of the viewing distance between the eye position of an observer and the plane of a stereogram rather than by altering the size and its arrangement of basic patterns which construct the plane images for steropsis. The visual effect of depth perception in the modified digital stereogram using sharpening filtering operation are discussed in connection with the modified various stereograms under the specified conditions: the number of pixel resolution and color bit levels.
