Abstract: A system, device, and method for minimizing terrain content in an image are disclosed. The terrain content minimization system may include a source of navigation data, a source of first surface data, and an image generator (IG). The IG may be configured to acquire navigation data; acquire first surface data; identify first surface data as a function of an elevation range; generate first pixel data; generate second pixel; and employ at least one of the first pixel data and the second pixel data. Second surface data could be comprised of a first subset of the surface data, and the third surface data could be comprised of a second subset of the surface data not included in the second subset of the first surface data. In addition, the pixel data could be representative of an image of terrain of the surface data.

Abstract: A series of printing plate imagers for imaging lithographic printing plates onto a continuous web are combined in a single imaging process line. The imageable web is passed through a series of properly spaced imaging stations in the line with multiple plate sections being selectively imaged in one or another of the stations or with each individual plate section being partially imaged in two or more stations. The imaging stations may operate in different modes, such as the digital mode with a laser and the analog mode with actinic radiation, with the prepared web capable of being imaged by either of the modes.

Abstract: The invention provides a hologram-recording subject plate comprising a block and a variety of subjects fixedly contained therein, which ensures easy, stable yet continuous recording of a multiplicity of identical holograms or different holograms reconstructible by illuminating light, , a hologram-making method using the same, and a hologram-recorded article. The subject plate comprises a transparent solid block and a hologram-recording subject contained therein. A photosensitive material film is applied directly onto one surface of the subject plate, and the subject plate is then irradiated with laser light through the photosensitive material film. Such simple operation enables a multiplicity of identical holograms to be recorded in an easy, stable yet continuous manner.

Abstract: A compact print making device by which a desired imprint figure can be made easily in a short time. This print making device employs a resin seal face member, a part of which receives light having a wavelength within a predetermined range and thus is put into a state different from the state of the remaining part thereof and is adapted to have an uneven face formed by being acted upon by a predetermined fluid. The resin seal face member and an original picture representing an imprint figure are arranged with the original picture just in back of the resin seal face member. Imprint figure information representing the imprint figure shown in the original picture is taken in by an information reading mechanism. A negative film making unit is driven according to the imprint figure information so as to produce a negative film. Then, the produced negative film is carried to an irradiating position. Subsequently, a light irradiating unit irradiates the resin seal face member with light through the negative film.

Abstract: The present invention relates to a machine for facilitating the continuous exposure of laminar photosensitive materials placed in contact with original films. The machine includes a planar slit through which the photosensitive materials are guided, the slit being defined by a rigid planar plate of light-transparent material which is superposed on a flexible supporting and sliding surface and acts thereon with a predetermined force to ensure the contact of the photosensitive materials. Light-emitting devices are further located beyond the plate on the side opposite to the supporting surface, and at least one pair of motorized conveyor rollers is arranged upstream of the inlet of the guiding slit for continuously advancing the photosensitive materials.

Abstract: The apparatus comprises a device for forming a latent image on a negative film according to data stored on a base medium; a first pair of transport rollers for pinching and carrying simultaneously the negative film and a receiving strip into a superimposition zone, the exposed film being developed into a treatment bath along said superimposition zone and a positive image being transferred by diffusion onto the receiving strip from the negative film; a second pair of transport rollers placed at the outlet of the superimposition zone, for pinching and carrying the receiving strip only; and registering means for sensing the advancing movement of the receiving strip and for controlling intermittently, at time intervals determined by the detection of guidemarks formed on the receiving strip, the production on the negative film of an image comprising a set of data stored discontinuously on the base medium.

Abstract: A data converting method for reordered prints in which print data given in the terms of a length from the end of a film strip is converted into a data from the end of said film strip with reference to a notch. A length from the end of the film strip to a frame to be printed according to the reorder is measured on the basis of the print data, so that a notch formed at a portion other than that corresponding to said length is accepted as information of no print, whereas a notch formed at the corresponding portion is accepted as information of print. In case there is formed no notch at the portion corresponding to the frame to be printed, a notch is newly formed with reference to the frame of the corresponding portion and the newly formed notch is accepted as information of print.

Abstract: A photographic reproportioning apparatus for transferring an image from a sheet member to an arcuate image on a photosensitive sheet has first and second travel boards movably supported for movement in a linear direction. A light shield having a uniform exposure line and a taper exposure line is located over the travel boards. Light projected through one of the exposure lines exposes a photosensitive sheet on movement of the sheet under the exposure line. A radius attachment having a circular member is drivably associated with the second travel board to move a photosensitive sheet in an arcuate direction. The sheet member carrying the image is attached to the first travel board and moves in a linear direction whereby the linear image is projected by light passing through the tapered exposure line in an arcuate pattern on the photosensitive sheet as the photosensitive sheet and sheet member having the image pass under the tapered exposure line.

Abstract: A method and apparatus for obtaining a distorted photographic reproduction from a negative photographic image, in which a sheet of photosensitive printing paper is attached to a planar surface of a table, the image negative is placed over the paper and a slitted mask is placed over the image negative. The image negative and the mask are moved laterally relative to one another and to the paper while the mask is exposed to a light source. To obtain a circular reproduction the mask is held stationary and the printing paper is rotated about an axis intersecting the slit while the image negative is moved laterally with respect to the slit.

Abstract: A photographic exposure apparatus and method for preparing production artwork of an image to be reproduced by photo-engraving. Prior art handwork or manually operated devices employed in modifying artwork images required high levels of skill and considerable time to achieve satisfactory results.The subject apparatus includes a movable panel superposed on a stationary plate for supporting a film containing an image to be reproduced in contiguous contact with a light sensitive sheet superposed on the stationary plate. An eccentric motion dial guide connected with a drive motor and connected with the film support panel is manually adjusted and the motor energized for orbital movement of the film support panel in a path of predetermined magnitude during exposure of the image on the light sensitive sheet.

Abstract: A contact printer, for exposing light sensitive sheets to relatively large size drawings and the like for making accurate duplications, is formed of an endless, movable, support belt having a flat support surface which is overlapped by a movable transparent belt. The drawing and sheet are overlapped and fed between and move in a longitudinal direction with the two belts. The overlapping portions of the transparent belt, the drawing and sheet are all flattened and tightly clamped together against the flat support surface by a vacuum system. Such system includes closely spaced, transversely extending, grooves formed in the surface of the support belt. The grooves open endwise into longitudinally extending border portions which are formed along the side edges of the support belt. A row of holes through at least one of the border portions passes over a vacuum chamber. Thus, air is evacuated through the grooves and out through the holes to the chamber.

Abstract: A photographic exposure unit for making a reproduction of non-dimensional engineering drawings to very close tolerances. The original drawing and the film are driven by a travelling vacuum system through a light exposure unit. In all cases, the exposure is made while the original drawing and film are held in close contact one against the other during their conjoint passage through a flat exposure area.

Abstract: An apparatus and method to position a moving continuous strip master and a moving continuous strip duplicate for copying film images from the master to the duplicate. A vacuum is applied to a housing, the walls of which are partially formed by surfaces of longitudinally extending adjacent rollers. The master and duplicate are inserted through adjacent roller pairs and both sides exposed to a vacuum within the housing. The master and duplicate are removed from the housing with confronting surfaces in contact through a third adjacent roller pair. As a result of the vacuum created between the confronting strip surfaces and atmospheric pressure on opposite strip surfaces the relative position of the master to the duplicate is maintained until exposure to a light source is complete.
