Abstract: PROBLEM TO BE SOLVED: To easily form the picture for stereoscopic vision from a parallactic original picture by automatically setting the coordinate data within the range from the spatial coordinate data of the maximum and minimum values which determine the range of the parallax and forming plural picture data having parallax information. SOLUTION: A data input section 1 inputs data to a stereoscopic picture assembling and processing control section 3 from a stereoscopic picture data generating section 2. As to the spatial coordinate data, the not-pictured or not-generated coordinate data within maximum and minimum values are automatically set and plural picture data having parallax information are formed. The section 3 divides and processes inputted picture data (a) and (a'), forms plural picture elements and generates a stereoscopic picture by synthesizing each element. These data are stored in a storage section 5 and the stereoscopic picture is outputted to a processing section 7 based on the commands from an output command section 6. Then, the picture is printed and outputted on a prescribed sheet and a picture element forming sheet 9 is obtained.

Abstract: PURPOSE: To clearly discriminate the copy made by means of a copying machine by combining both the pattern in which two kinds of picture pattern elements having the directions of diffraction grating different by 90 degrees each other are combined, and the pattern in which the directions of the picture pattern elements have been turned by 90 degrees respectively are combined. CONSTITUTION: A diffraction grating pattern, is provided with a pattern A in which a letter 1 having a direction of 90deg. and a background 2 having a direction of 0deg. both having the same space frequency of a diffraction grating are combined, and a pattern B in which a letter 3 having a direction of 90deg. and a background 4 having a direction of 0deg. are combined. In the other part except the above, considering the visual effect, either of the dot angle constituting the diffraction grating or the space frequency, or both of them may be delicately changed. Thus, even if a copy is made by a monochromatic copying machine or by a color copying machine, the copying mode by means of the combined pattern A and the copying mode by means of the combined pattern B are clearly different from the way of seeing of the actual combination of A and B by means of the naked eye.

Abstract: PURPOSE:To provide the system which generates image data for stereoscopy for easily obtaining an image sheet for stereoscopy without requiring a troublesome optical composing process which performs composition on a different film over fine-pitch movement through a lenticular lens. CONSTITUTION:This image data generation system consists of a parallax image storage means (a) stored with plural image data having mutual parallax, a mask means (b) which is in a comb shape and constant in the pitch of its comb part, a mask assigning means (c) which reads the image data out of the parallax image storage means (a) in order and assigns the mask means (b) to a specific position on the image data, an image cutting means (d) which cuts image data at the part surrounded with the mask means (b) assigned by the mask assigning means (c), an image storage means (e) which temporarily stores the image data cut by the cutting means. and an image composing means (f) which reads image data out of the cut image storage means (e) and performs composition at a specific position.
