Abstract: System and method forms a lenticular viewing card having viewable depth or motion images by processing an original image into digital form and sampling and shifting the processed original image into at least two frames of images shifted perpendicular to the lenticular direction from each other by being sampled at different points. These frames of images are sliced and interlaced into a merged image that is printed and positioning into a viewing position with a lenticular lens sheet to permit a sequential viewing of the frames making up the merged image as a function of a user's viewing angle.

Abstract: An apparatus is provided that includes at least one of a lenticular screen and a barrier screen, an image bearing member, and flexures coupled to the screen and the image bearing member that permit relative movement between the screen and the image bearing member. In one embodiment, an image retaining member is provided that includes a slot that receives the image bearing member. In this case, the flexures are coupled to the image bearing member via the image retaining member. A mechanism is provided to supply audio that is synchronized to the movement of the image bearing member relative to the screen. The audio is generated from audio data that is either stored on the image bearing member or on a separate storage medium. The audio data can be stored in magnetic form, optical form or as digital data in a semiconductor memory device. Accordingly, the observer is provided with audio that is synchronized with the image display.

Abstract: A method for forming an integral image on an image receiving medium which image is aligned or alignable with an integral lens sheet having a back side and a plurality of separate lens elements on a front side, and apparatus which can perform such a method. The method includes: directly sensing the location of each of a plurality of reference elements on the lens sheet which reference elements are separated in a same direction the lens elements are separated; and writing portions of the lenticular image on the image receiving medium each of which is associated with a corresponding lens element, in accordance with the sensed positions of the reference elements; wherein each of a plurality of image portions is written at a position which is a function of the directly sensed location of at least one selected reference element, the functions for at least some of the plurality of image portions being based on at least one different reference element.

Abstract: A method of improving uneven illumination in a photographic printer having an original image position and a light source to illuminate the original image position, which light source may illuminate the original image position non-uniformly, the method comprising: first forming a mask by exposing a photographic element to the light source and processing the element to form a negative image of the light source at a filtering position between the light source and the original image position; and positioning the mask at the filtering position. A second aspect of the method uses an electronic processor and gathered illumination data, to generate a mask.

Abstract: A method for forming a lenticular image on an image receiving medium on the back side of a lenticular lens sheet, which sheet has a plurality of generally parallel lenticules on a front side:(a) at a sensing station, directly sensing the actual position of a reference element associated with a lenticule;(b) writing a portion of the integral image corresponding to a lenticule associated with the reference element the actual position of which was previously sensed in step (a), on the image receiving medium in accordance with the sensed actual position; and(c) moving at least one of the lens sheet and sensing station in relation to the other, in a transverse direction in relation to the lenticules, so that another lenticule can have its associated another reference element directly sensed at the sensing station. An apparatus which can execute the method is also provided.

Abstract: A method of improving uneven illumination in a photographic printer having an original image position and a light source to illuminate the original image position, and an exposure position at which a light sensitive element is positioned for exposure, wherein the exposure position may have an inherent non-uniform illumination absent the original image, the method comprising:inputting into a computer, data representative of illumination at multiple laterally spaced locations positioned in a direction from the light source to the exposure position;processing the data in the computer to form an illumination correction function with a visually indistinguishable resolution.The illumination correction function is typically applied to an original image signal so that when the original image is printed and positioned at the original image position, the inherent non-uniform illumination at the exposure position is reduced. This corrected original image is then typically printed on a support.

Abstract: A method of improving uneven illumination in a contact printer having an original image position and a light source to illuminate the original image position, which light source may illuminate the original image position non-uniformly, the method comprising: first forming a mask by exposing a photographic element to the light source and processing the element to form a negative image of the light source at a filtering position between the light source and the original image position; and positioning the mask at the filtering position. A second aspect of the method uses an electronic processor and gathered illumination data, to generate a mask.

Abstract: Apparatus for determining parameters of any number of selected regularly or randomly oriented particles, or images or image patterns thereof, of various size and shape lying within a discrete region. A scanning device is swept over the discrete region causing the generation of electrical signals in response to the interception of the boundaries of one or more of the particles. Apparatus, including, for example, a light pen, for use in cooperation with a display of the feature images is operated to best identify, select or prepare for analysis features of interest within the discrete region. In cooperation with such apparatus appropriate logic and electronic circuitry which is adapted to receive the initially generated signals provide, in response thereto, other signals related to the feature or features of interest and any particular parameter related to those features.
