Abstract:
The invention provides a lenticular lens type three-dimensional image display device and a method of fabricating the device without a need for a clear plastic substrate transposed between the image and lenticular lenses. The device can be obtained by directly printing curable coatings onto the image, making them particularly well suited for volume production. The combination the image printing and application of curable coatings process can be joined together to conduct the single pass-process. The single pass-process allows for flexibility of the printing only selective areas of the substrate. Moreover, this process allows the device to be recyclable.
Abstract:
Multiple images of a patient are obtained by one or more medical imaging apparatus (102). A plurality of the images are selected (108), interlaced with one another (109) and printed (114) on a lenticular media. Text may be input and combined with one or more of the selected images. The interlacing (109) and printing (114) are such that viewing the lenticular media from a succession of viewing angles provides a sequential spatial walk-through or time history of an image region of the patient. Images from two or more medical imaging apparatus may be overlaid (109) to provide a sequence of multi-spectral images.
Abstract:
The filmless method and printer for making 3D and animation pictures using a digital reflection-type matrix display device (40) such as a digital micro-mirror device or a matrix display to sequentially display a plurality of 2D views, a light source (20) to illuminate the display device to produce a reflected beam, and a projection lens (60) to form an image from the reflected beam and expose it on a lenticular print material (90). To fill the image area underlying each lenticule on the print material (90), each 2D view is projected at a different angle. Two methods can be used: 1) in the scanning method, two of the three elements including the display device (40), the projection lens (60), and the print material (90) are moved to different positions to change the projection angle; 2) in the non-scanning method, the projection lens has a large aperture sufficient for covering the total viewing angle of the lenticules. To change the projection angle, the aperture of the projection lens is partitioned into a plurality of sections so that the image of each 2D view is exposed on the print material through a different aperture section. Preferably, with the non-scanning method, the image displayed on the display device is enlarged and formed on a diffuse screen and the image so formed is then exposed on the print material by the projection lens. The 2D views for making the 3D pictures can be electronically aligned before they are displayed on the display device. Thus, the key subject alignment process during printing is eliminated. The matrix display can be a video monitor or a light valve, such as an LCD or LED panel. Computer generated images can be used.
Abstract:
A 3D printer for producing 3D photographs on lenticular print material (80) in which a video monitor (50) is used to display stored digital 2D images of different views of a scene for exposure. Prior to printing, one of the stored 2D images is displayed on a viewing monitor (30) and the key subject image of the displayed 2D image is selected. Based on the location of the selected key subject image, the computer (10) searches for the key subject location for each of the other stored 2D images and electronically shifts the 2D images so that the key subject location of all different views is the same. During printing, the electronically shifted 2D images are sequentially displayed on the video monitor (50) and projected through a projection lens (65) onto the lenticular screen at different projection angles.
Abstract:
The invention relates a method of and a device for producing a panoramagram (30) for providing an autostereoscopic image using a digital processing device. A first digital image recording and a series of second digital image recordings of an object (25) are supplied to the processing device, wherein each of the second image recordings presents the object (25) from a different viewing angle (λ', λ", λ'"). The processing device produces a series of third digital image recordings by combining part of the first image recording and a respective second digital image recording dependent on a particular viewing angle (λ', λ", λ'"). From this third series of image recordings image slices (33', 33", 33"') are interleaved by the processing device into a panoramagram (30), such that the autostereoscopic image hereof provides a three-dimensional impression of the object (25) in an environment formed by the first image recording.
Abstract:
A method of creating a lenticular imaging article. The method comprises printing an interlaced composite image according to a reference grid of a printer, providing a lenticular lens sheet having a plurality of parallel lenticular lines between a plurality of lenslets, selecting an acute angle for an intersection between the first and second axes according to a function of a resolution of the interlaced composite image and a pitch of the lenticular lens sheet, and positioning the lenticular lens sheet so that the intersection forms the acute angle.
Abstract:
A new method for making display products (152) that generate special visual effects with autostereographic, dynamic, alternating, animated, and morphed images used in conjunction with lenticulated arrays for marketing and informational purposes. The special imaging effects, which can be integrated with discrete lenticulated container structures for data storage media and other contents, are achieved by digitally sampling and formatting source images with resampling procedures and then generating a merged image file that serves as the digital input for color printers (122) or digital printing presses (120). The sampled images are printed on substrates along with registration lines or on preperforated stock preformatted for use with a corresponding lenticulated component. Afterwards, the images are separated from the substrate by either cutting them from the substrate using the printed registration lines (158) as quides or breaking them out along the preperforated lines.
Abstract:
A 3D printer that has a chemical processor in-line with the printer. The preferred printer is a single-stage printer that uses two video cameras with different magnification powers for acquiring images from 2D negatives for editing and key subject aligment. One video camera takes full view image for key subject selection and picture cropping, the other video camera which is used for acquiring image data for key subject alignment sees only an enlarged section of the image around the key subject. The single-stage printer uses an automated image matching algorithm to find the relative location of the key subject in each negative frame. The single-stage printer also includes a chemical processor so that photo processing can be part of an in-line printing process.
Abstract:
A 3D photographic printer and method of printing using a single large aperture projection lens (55). The lens aperture is sufficient to cover all the projection angles necessary for filling the area under each lenticule with compressed images during printing. The printer uses an aperture plate (60) which is designed such that only one section of the aperture is opened at a time so that one of the 2D images (30) is exposed through the projection lens (55) at a proper projection angle onto the print material (90). With such an arrangement, the projection lens (55) and the print material (90) are not required to move to different positions during printing.
