摘要： A film image retrieval and scanning apparatus having split first and second optical paths with each optical path being precisely aligned with the other, and each path containing coupled zoom optics. The first path projects a film image onto a first scanner array in the first path to provide a real time display of the image on a TV monitor. The second optical path projects an image onto a second scanner array, which may have a higher resolution than the first array to provide an analog signal that is converted to a digital signal of the image that may be stored, or transmitted on a network, or both. The first scanner provides a real time image and serves as a viewfinder that can be used to locate the proper position of an image; thus ensuring that the image will be aligned with the second array so that it can be scanned by the second scanner array when desired.

摘要： The converter comprises a pick-up device (PD) for picking up a negative (PH), a picture signal processing circuit (PC) for obtaining a picture signal via a signal inversion (IN) and fixing at a black level and a white level, which signal is suitable for display on a television display screen (TVD), and a time signal generator (TG) for supplying at least one adjusting signal (WS) to a black level adjusting circuit (BA). To realize a simple adjustment, the negative (PH) can be picked up by a sensor (FT) in the converter with a picture content part (PP) and beyond it a bright part (WP) by way of a sequential or simultaneous pick-up, respectively, while the sensor (FT) has a black level reference member (BR). Essential is the use of the adjusting gate signal (WS) for the black level adjusting circuit (BA) when the said bright part (WP) is being picked up.

摘要： Mode selection switches (76, 96, 98) selectively interconnect a sensor line shift timing generator (76) with one of three signal sources - (1) a conventional raster scan timing signal from a raster scan sync generator (70), (2) variable speed external timing signals from a tachometer (32), and (3) fixed speed timing signals developed from the horizontal timing signals of the raster scan sync generator. In a time delay and integration mode, the sensor line shift timing generator causes the CCD arrays of an image section (22) and storage section (24) to shift pixel values down the CCD arrays at a rate commensurate with the external timing signal. As a spot of light emanating from a portion of an object moving through an examination region moves along the CCD array, a corresponding pixel charge is shifted through the CCD array at the same speed such that the same pixel charge integrates light from the same spot as it moves the entire length of the CCD array. An output register timing generator (80) generates timing signals for output registers (26 ) such that an output signal is produced that is compatible with EIA-170 television signal standard. In the conventional raster scan mode, the camera works as a conventional video camera. When connected to the variable frequency timing signal, the video picture scrolls down the TV monitor clocked by the tachometer in proportion to the speed of the conveyor. In the calibration mode, the image scrolls down the video screen at a fixed rate.

摘要： In a preferred system a light source provides a light beam which illuminates a film image. A lens is placed in the path of the light beam to focus the image from the film on to a tri-linear color sensor. The length of each of the image sensors and spacing between sensor elements is selected in order to correct for distortions lateral chromatic aberrations in the line scan direction. Longitudinal chromatic aberrations are corrected by tilting the tri-linear sensor in the image plane to align the center of focus for the red, green and blue sensors with the center of focus for the red, green and blue components of the beam, respectively.

摘要： A method and apparatus for signal companding is disclosed that incorporates a log-offset companding technique to provide both a high bandwidth over the dynamic range of the signal being processed as well as temperature stability. In addition, the incorporation of log-offset companding technique provides the capability of generating a family of transfer curves. The ability to provide a family of transfer curves is particularly useful, for example, in telecine machines adapted to scan more that one type of film.

摘要： An apparatus and process for providing an automated edit procedure between film and video formats is provided wherein a video edit becomes within one video field the exact replica of a film edit. Film frames (1/24th of a second) are read by video scans (1st and 2nd fields in 1/30th of a second) in a 3:2 pull down wherein successive movie frame scans are provided with four classes of video scans. These classes of video scans include (Class A) odd/even scans; (Class B) odd/even/odd scans; (Class C) even/odd/scans; and, finally (Class D) even/odd/even scans. All edits are limited to film frame edits. Each time a film frame edit is converted to a video edit decision, the system looks at the edit out frame type and/or the edit in frame type and the cumulative current overall time differential between the video run time and the film run time for the edit. Frames are added or subtracted to keep the total error within + or - one field and a new cumulative error calculated for the next sequential edit. All edits are made between respective odd to even. The system is preferably used by taking a film edit decision list, recording the desired edit decisions on a film format with respect to a video master, and thereafter reprocessing those decisions in accordance with the protocol set forth above. There results a side-by-side video and film cut which are indistinguishable in temporal detectable sound and motion characteristics.

摘要： An image transducing apparatus is disclosed. An object to be imaged is located in a fixed object plane. A lens focuses the image of the object upon an imaging plane. A photoelectric transducing array having a plurality of congruent, discrete, spaced-apart transducing elements arranged in an array is located in the imaging plane and provides an electrical signal representative of the light intensity thereon. The photoelectric array is movable on a microstage which is movable in two axis. The microstage is mechanically displaced in a direction parallel to the imaging plane from a first position to a plurality of subsequent positions. The distance from each position to a subsequent position is less than the dimension of a transducing element along the direction of the displacement. The photoelectric array is moved and is stopped at each of the displaced positions where an electrical signal from the photoelectric array is taken. The signals from each of the positions traversed by the photoelectric array is combined to form an electrical representation of the image of the object.

The apparatus also comprises a selection circuit for receiving the output current signal of the photomultiplier, a voltage signal detected by the voltage detector, and an output of the comparator, selecting the output current signal of the photomultiplier when the output current signal of the photomultiplier is equal to or lower than the reference value, and selecting the voltage signal when the output current signal of the photomultiplier is higher than the reference value.

摘要： A telecine apparatus uses a line array electro-optical image transducer which is illuminated with bias light in addition to the projection light passing through the film. The bias light serves to operate the transducer on a linear portion of its characteristic, and the bias light is pulsed on during the integration periods of the transducer so as to give an accurate and reproducible control of the bias value. The transducer itself has a controllable variable integration period.
