摘要:
An apparatus and method of creating depth images with different depth image scenes being projected at different viewer orientations. At each of the orientations a different perspective series is provided to the viewer. To provide the different depth scenes at the different orientations, different depth content image slices of different depth content scenes are interleaved behind lenticules of a lenticular faceplate. The interleaving of different depth content scenes on an imaging substrate is accomplished by writing to a print file depth images of the different depth content scenes in successive positions prior to driving the printer with the print file contents to record on the substrate. The substrate is then attached to the lenticular faceplate.

A printer device for lenticular photographic images easily transforms electronic image files into photographic hard copy. The printer device includes a cathode ray tube screen and a projection lens. A filter wheel may be used for inserting optical filters into the optical path of the projection lens. A lenticular photographic print assemblage is aligned and affixed at the focal plane of the projection lens. The lens and the image on the cathode ray tube screen are then moved in differential amounts in the direction parallel to the plane of the aligning and affixing process, and normal to the axis of the lenticules on the lenticular photographic print assemblage. Finally, an electronic video display driver and computer coordinate the motions with changes of the images displayed on the cathode ray tube to allow the correct exposures of color and angular perspective views inherent in the image files onto the photographic emulsion coating of the lenticular photographic print assemblage, for the subsequent developing and autostereoscopic viewing.

An integral, autostereoscopic three-dimensional image suitable for lenticular display is generated from a plurality of image perspectives by interpolating additional images from hypothetical perspectives, as follows. Initially, actual image signals are generated from a plurality of actual images obtained from a plurality of actual image perspectives. The additional images are obtained by operating upon the actual image signals and forming interpolated image signals from hypothetical image perspectives. Finally, an integral three-dimensional image is generated from the combination of images obtained from the actual image perspectives and the hypothetical image perspectives, and is suitably displayed. According to one suitable display, the integral image may be exposed upon a photosensitive sheet that is attached to a lenticular faceplate for subsequent viewing.

An optical tape for use decoratively includes a back portion of a first color, a serrated front portion made of a clear plastic. The serrations include alternating wide and narrow grooves such that a side of a wide groove adjoins a side of a narrow groove at an angle of substantially 90.degree.. The sides of each narrow groove have a second color. When the tape is viewed from a distant point, only the first color of the back portion is seen, but when viewed from up-close, substantially only the second color of the narrow grooves is seen.

A method, and apparatus and lens sheet manufacturing process which utilize the method, of evaluating the quality of a lenticular lens sheet having a front side carrying a plurality of elongated parallel lens elements, and a back side. The method includes:(a) illuminating the sheet from one of the sides with a light source so that the light passes through the sheet and is then reflected from a reflector behind the other side to pass back through the sheet; and(b) comparing an observed feature of a pattern of the reflected light which has passed back through the sheet with a corresponding reference feature to provide an indication of the lenticular lens sheet quality.

A CRT display system includes a CRT with a lenticular material placed upon the outward face of the CRT. The system further includes a sensing device in the field of view of the CRT and control circuitry connected between the sensing device and the CRT. The control circuitry is responsive to signals received from the sensing device to control the synchronization and formation of a composite of strips of visual input from four different perspective views of a scene to be presented on the CRT through the lenticular material such that a viewer perceives depth in the composite scene displayed on the CRT.

An improved stereoscopic picture, comprising:(a) a lenticular faceplate material having a predetermined number of lenticules, the lenticules having a given pitch and a given subtended primary angle; and(b) a photographic receiver mounted on the lenticular faceplate material and on which are recorded sets of right and left perspective views of a first pair of stereoscopic pictures, the lenticular faceplate material and the photographic receiver being aligned so that each set on the photographic receiver corresponds to an associated given lenticule of the lenticular faceplate material, the width of the sets of right and left perspective views being less than the pitch of the lenticules.
摘要:
A system and method in which a size of a pixel used to print lenticular depth images is changed to remove overlap in the slow scan print direction. A space adjustment of the space between scan lines can also be performed to remove pixel overlap. The pixel can also be elongated in the fast scan direction reducing fast scan resolution. An elongated pixel can be combined with skip space adjustment to remove pixel overlap. Printing the image lines in the fast scan or dot movement direction improves image quality. The print resolution in the fast scan direction can be reduced by increasing the printing rate compared to the data rate of the supplied image data, thereby cloning pixels in the fast scan direction, while maintaining a normal slow scan speed to normally print lines. Combinations of the above approaches to directional printing, removing slow scan pixel overlap and reducing file size can be accomplished.

A frame that includes a depth image lenticular photograph as the frame surrounding a planar print or object of interest to the viewer. The frame can be a reflection print or a backlit transparency of a real object or a graphical creation.
摘要:
A method and apparatus which provides alignment lines adjacent to a lenticular image. The alignment lines are projected through a lenticular overlay and used to align the overlay to the image. The alignment apparatus uses a light sensor and a computer to detect either changes in brightness or changes in a Moire pattern of the lines to effect rotational alignment and to detect either centeredness of the lines or brightness changes in the lines to effect translational alignment as the overlay is rotationally or translationally moved with respect to the print by the computer. An increase in brightness indicates motion toward either rotational or translational alignment. A constant brightness along the lines indicates rotational alignment while a peak in brightness indicates translational alignment.
