Patent number: 5687011Abstract: Digital signals are generated and stored for each pixel of a frame of a video originated material. A computer reads the digital signals and converts them to binary image data by employing a program to reassign color and black component values for each pixel. The component value reassignments performed by the computer are a primary component modification step. The primary component modification step, in one embodiment, comprises component modifications by selected image zones of the video originated images, based on color data within actual filmed images originated simultaneously as the video images. The film origination and video origination are preferably provided by the same camera, with image data delivered for both through the same lens by way of a "beam-splitter" device. The primary component modified digital data is assembled and a secondary modification may also be performed. Film stock emulsion grain patterns are introduced to the images in the second modification step.Type: GrantFiled: March 20, 1995Date of Patent: November 11, 1997Inventor: Craig P. Mowry

Patent number: 5406326Abstract: Digital signals are generated and stored for each pixel of a frame of a preferably high definition video originated material. A computer reads the digital signals and converts them to binary image data by employing a selected look-up-table program to reassign color and black component values for each pixel. The programs applied in the component value reassignments are compiled from, and based on, comparative digital video component results of telecined film stocks' responses to selected color and grey scale gradients as charted against a selected video unit's response to the same charts under a selected number of identical lighting circumstances. A projector unit projects the high definition video frame through a macro lens onto a strip of exposed and processed motion picture or other photographic film of an optional grey scale gradient and thus grain pattern density.Type: GrantFiled: May 20, 1994Date of Patent: April 11, 1995Assignee: Harry E.

Patent number: 5387929Abstract: A subject image being electronically transferred from a first medium to a second medium is accomplished through tone scale tracking. Three monochromatic channels representing the subject image are generated from the first medium. In a preferred embodiment, an image processing system provides color correction for each channel by compensating for film and video characteristics that cause a degradation of color from the original subject image. Calibration of the system is provided by means for an operator to specify tone densities for the second medium that correlate to signal levels derived from the first medium for each channel. The image processing system tracks the tone densities calibrated to provide enhanced film masking. The image processing system also performs characteristic curve processing in accordance with a Hurter-Driffield (HD) curve.Type: GrantFiled: November 20, 1992Date of Patent: February 7, 1995Assignee: Sony ElectronicsInventor: David C.

Patent number: RE38626Abstract: A video camera mounted on a parking enforcement patrol vehicle and connected to a computer near the operator. The system is driven along a patrol route where parked vehicles are governed by a posted time limit. The system enforces the local parking regulation by automatically determining whether or not each parked car has been parked longer than the posted time limit. Violations are detected by applying a License Plate Recognition algorithm to the images. Each license plate number is time-tagged, geo-referenced and entered into a local database. When the patrol vehicle re-traces the patrol route after the posted parking time limit has expired, the database is searched to flag vehicles that were observed at the same location during the previous circuit and therefore in violation of the parking regulations. When the system detects a parking violation, it prints a parking citation that the operator affixes to the offending parked vehicle.Type: GrantFiled: June 21, 2002Date of Patent: October 19, 2004Assignee: Visionary Technology, Inc.Inventor: Peter J.
