Appl. No.:

7/348551

Inventors:

Eugene J. Dwyer - New York NY

Silhouette Technology, Inc. - Morristown NJ

International Classification:

G03B 2772

US Classification:

355 20

Abstract:

The present invention relates to a method and apparatus for reducing the effect of recording errors on images and information which are recorded in sections onto a recording medium. Recording errors can detract from the quality of a recording particularly at the boundaries of recorded sections. The present invention introduces a number of methods which reduce the effect of recording errors by distributing the errors smoothly over areas of the recording, by modifying the recording level near the section boundaries, by modifying the recording process near the section boundaries, by modifying the shape, size and orientation of the recorded sections, by varying the position of the transition point from one section to an adjacent section and by introducing an overlap region which allows the section boundary to be modified.

Abstract:

A photographic system for accurately reproducing encoded information onto a recording medium is disclosed. The system includes an image/light source, a feedback sensor, a lens assembly, a controller, a recording medium assembly and a reading sensor, whereby encoded information is decomposed into sections, adjusted, and transmitted such that the sections are correctly aligned and smoothly joined into a final reproduced image. According to the present invention, encoded information can also be digitized and read.

Abstract:

An apparatus for recording an image onto a light recording medium (16) by sequentially recording a plurality of sections onto the light recording medium includes a light source (120) which emits light at a position which is movable over a light emitting area (21) of the light source controlled by a controller (13), the position of the light being subject to deviation from a desired position of the light emitting area of the light source which corresponds to a position to be recorded on the recording medium which has recording position coordinates; a translator (702) having controllable positions for moving the recording medium relative to a light source during the recording of the plurality of sections of the image; a light transmitting mechanism (14, 15) disposed between the light source and the recording medium for transmitting the light from the light source to the recording medium; a light position sensor (142) having a target area optically coupled to light emitted from a plurality of positions within the light emitting area of the light source used for recording for detecting the position of the light intersecting the target area of the sensor from the light emitting area of the light source and generating a signel dependent upon the light intersecting the target area; and wherein the controller, responsive to the signal, produces a correction parameter and sequentially controls the recording of the sections to record the image by controlling the position of the light on the light emitting area of the light source.

Inventors:

Eugene J. Dwyer - New York NY

Assignee:

Silhouette Technology, Inc. - Morristown NJ

International Classification:

G09G 320

US Classification:

345 31

Abstract:

An optical display system is disclosed having a preferred application in a helmet mounted heads-up display. The display system includes an image source (42-46) for generating an image which includes a plurality o fields sequentially displayed by the image source to form the image with a two-dimensional array of pixels forming each field and the fields having a spatially modulated light intensity. An image display (50) is coupled to the image source for displaying the fields. The image display produces for each field a two-dimensional display having a fixed number of light emitting points (65) which are disposed along each dimension of the two-dimensional array with each light emitting point being spaced apart from adjacent light emitting points by a fixed distance. An actuator (52) is provided for moving the light emitting points in unison in a repeated pattern relative to a field of view of the displayed image with motion of each of the light emitting points along two axes during the repeated pattern delineating an area which is a fraction of an area of the displayed image produced by the image display. Movement of the light emitting points through successive positions of the repeated pattern is synchronized with the successive display of individual fields by the image source.

Abstract:

The invention is an improved apparatus for recording an image onto a light recording medium by sequentially recording a plurality of sections onto the light recording medium which constitute the image and further an apparatus for reading previously recorded information disposed on a recording medium (162). The invention utilizes a light position sensor (201) having a target area having a plurality of apertures (604) including at least one line segment coupled to light emitted from a plurality of positions within the light emitting area (120) of the light source (120) used for recording for detecting the position of the light intersecting the target area (201) of the sensor from the light emitting area of the light source and generating at least one signal dependent upon the light intersecting the target area. A controller (13) responsive to the at least one signal, produces at least one correction parameter, sequentially controls the recording and reading of sections (F1-FN) to record or read the image by controlling the position of the light on a light emitting area of the light source as a function of the at least one correction parameter during the recording or reading of each section to cause the light to move to coordinates on the light emitting area of the light source to cause the light to intersect the recording medium at the recording or recorded position coordinates and controls the position of the translator for recording or reading each section.
