Abstract:
An apparatus for digitally archiving analog film images includes a support surface (58) on which an analog film image may be supported, and a digitizer (92) that is spaced from the support surface in a direction defining a Z axis perpendicular to the support surface. A light (84) transilluminates the film image and projects it toward the digitizer through an objective lens (94) which focuses the image. The positions of the digitizer and the lens along the Z axis are adjustable so that the size of the image projected onto the digitizing means can be varied. For example, it is possible to move the digitizer and objective lens between a range of enlarging positions in which the lens is closer to the film image than to the digitizer, and a range of reducing positions in which the lens is further from the film image than from the digitizer so that the film image may be either enlarged, reduced or reproduced at the same size before being sensed and converted into digital data.
Abstract:
A film video player (10) has film gates (14, 15) for mounting photographic film (F, F'). An imager has a lens (L) for projecting at least a portion of a film frame image from the film onto a sensor (S). The sensor converts an image to a video signal for video display. A zoom carriage (25) changes the magnification of the image with respect to the film frame image. A scan carriage (65) translates the sensor with respect to the film frame image in one axis, and a gear assembly (90) translates the sensor along a perpendicular axis as well as rotating it.
Abstract:
A method for controlling a scanning apparatus for scanning a continuously moved object (3) includes seizing the actual momentary position of the moving object (3), and controlling the time instant or period in which image information is captured by the scanning devices (6) in dependence of the actual momentary position of the object (3). The scanning apparatus in which the method is used includes a multiplicity (6) of line scanning devices arranged adjacent to each other in the direction of the movement of the moved object (3). Each of the line scanning devices has a multiplicity of pixels that are arranged adjacent to each other in a direction across a path along which the object (3) is moved. The pixels of the line scanning devices accumulate charges according to the amount of incident light. A controlling means (7) is provided for transferring the charges accumulated in individual pixels to pixels in the adjacent line scanning device in synchronism with direction of the movement and the speed of the moving object (3). The object (3) is illuminated or transilluminated by a light source (4).
Abstract:
A photographic film printer system comprising: a printer body; first means S2 disposed on said printer body for generating a position control signal in response to an exposure position control indicator 40a on a photographic film 1; second means S1 disposed on said printer body for generating a print size control signal in response to an effective exposure size signal 12a recorded on said photographic film 1; third means S3 disposed on said printer body for generating a print order control signal in response to a print order signal recorded on said photographic film 1; film feed control means 64, 56 disposed on said printer body for controlling feeding of the photographic film 1 based on said position control signal generated by said first means S2; mask control means 64 for varying an opening width of a mask 48 used to print an image in an exposure area of the photographic film 1 on print paper 46 in response to said print size control signal generated by said second means S2; and printing means disposed on said body 58-64 for performing photographic printing in response to said print order signal generated by said third means S3.
