Diagonal lenticular image system

Disclosed is a method and apparatus for aligning a lenticular image printed on a substrate with a lenticular lens sheet. The method comprises; fixing at least one set of differently colored alignment lines onto the substrate for projection through the lenticular lens sheet, positioning the lens sheet over the substrate, viewing at least one set of differently colored alignment lines as projected through the lens sheet, and adjusting the position of the lens sheet relative to the substrate according to a characteristic of the projected image.

System for aligning lenticular images using line sets with different

A system which captures multiple planar images of a scene taken from different perspectives and decomposes each of the captured those images into multiresolution images for storage in a distributable storage medium, such as an optical disk. The images on the storage medium are linked through a directory structure. During retrieval the user is allowed to browse various resolution images for selection purposes. After selection of the image, designation of the media type and designation of desired output resolution, the system reconstructs the images. The reconstructed images are converted into a depth image by interleaving slices of the images and then the depth image is output. Conversion into a depth image may require the creation of intermediate perspective views using interpolation.

Hierarchical storage and display of digital images used in constructing

Several different methods alone or in combination can be used to reduce image jump or stutter. The image plane on which the original image is taken can be mechanically or electronically rotated about a point of rotation in the scene. The number of original images which are viewed could be increased by interpolation. The subtended viewing angle of the viewpoints can be reduced and viewpoints within the subtended viewing angle can be increased by interpolation. Reduced subtended viewing angle images can be created for each eye. The depth of focus of the images can be changed by identifying the images that jump and blurring the images outside the area of interest. The original images can be processed to move the image plane further back from the objects in the scene. Some of the images ordinarily existing between the right and left eye perspectives can be eliminated. The objects in the background of the scene being photographed can be identified and shifted forward in the scene. The highest detail volume of the images can be identified and the images can be processed to rotate around the volume. The highest detail area can be identified and the original images processed to displace the images to minimize the movement of the highest detail area. The original images can be viewed and a point within each image identified to align the point from view to view using a linear or other transformation.

Method and apparatus for optimizing the resolution of images which have

A camera for recording motion sequences which may be selected for forming an integral image. The camera includes an image capture device for capturing a scene action as a motion sequence of image frame signals; and a first storage device for storing the motion sequence. A comb subset of the motion sequence is selected; and a second storage device which may be the same or different from the first storage device, stores the selected comb subset of the motion sequence. A method of obtaining in a camera such as the foregoing camera, a set of images from which a lenticular motion image can be formed, is further provided.

Camera and method for capturing motion sequences useful for integral

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:

Integral imaging lens sheets

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.

CRT printer for lenticular photographs

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.

Method and apparatus for improving electronic recording of depth images

An apparatus for forming an integral image element, comprising (a) a processor, (b) a printer to print an integral composite image on a carrier, the printer being capable of printing the image at a magnification which is under the control of the processor, (c) a positioning unit connected to the processor to position the printed image under control of the processor so that it can be viewed through an integral lens sheet, (d) a sensor unit connected to the processor to provide an indication of the magnification of the printed integral composite image with respect to the integral lens sheet, and (e) a magnification adjuster connected to the processor, which can vary the magnification in response to the indication. A method which can be carried out by the above apparatus, is also provided.

Apparatus and method for producing integral image elements

A method and apparatus for printing lenticular pictures includes imposing lines of information in the form of segmented images of a scene onto a light sensitive material. Alternate segments or lines are provided from different perspective views of the same scene to be printed. The light sensitive material has a transparent lenticular material attached thereto. The light sensitive material is exposed, from the side opposite the lenticular material, by light from an illuminated image. The exposure may be effected by optical projection or by contact printing or by CRT image projection or other device. A reference grid, having a pitch slightly different from the pitch of the lenticular material, is positioned on the lenticular material and is effective to cause a Moire pattern to become visible when the lenticular material is moved relative to the light sensitive material. The Moire pattern is used to adjust the position of the lenticular material or the negative, prior to exposure of the light sensitive material. After exposure, a reflective material is applied to the side of the light sensitive material opposite the side to which the lenticular material is attached, to provide a three dimensional print. In another example, several reference grids are used for additional accuracy of alignment.

Depth image printing method on precoated lenticular material

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.

Depth image display on a CRT

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.

Depth image object/picture frame

An improved stereoscopic picture, comprising:

Method for producing an improved stereoscopic picture and stereoscopic

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.

Depth image apparatus and method with angularly changing display

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.
