摘要： A method is described for processing motion picture scene data through a process in which the scene data is initially acquired from a film or an electronic camera and ultimately projected onto a screen, wherein image losses potentially occur during distribution and projection stages of the process. The method includes the steps of: (a) representing the scene data in a non-linear space; and (b) compensating for the image losses associated with the distribution and projection stages at a point in the process before they occur by converting the scene data into an intermediate space representing the space in which the losses occur and filtering the scene data in the intermediate space to compensate the scene data for the losses. Additional steps provide additional benefits, including the steps of: (a) digitally scaling the digital scene data anamorphically to provide an image that makes full use of the available film space on the film; (b) recording multiple intermediate prints from the digital scene data and performing a single printing step to make each release print from an intermediate print; and (c) using motion compensated frame averaging to digitally remove noise.

摘要： A system for compensating for film flutter in a motion picture film projector during projection of a motion picture film comprising multiple film image frames is described, the system comprising sensing the position of film image frames in a film gate of the projector relative to the focal plane of the projection lens assembly of the projector as the film image frames are being projected, and correcting the position of the film in the film gate of the projector or the position of the focal plane of the projection lens assembly to reduce the distance between the film image and the focal plane of the projection lens assembly as the film image frames are being projected, wherein the correction of the position of an individual film image frame in the film gate or that of the position of the focal plane of the projection lens assembly during projection of the individual frame image is based on the actual sensed position of the individual film image frame in the film gate, or on the position of a previously projected film image frame which was sensed as it was being projected.

摘要： A process and system for forming a video image with a telecine transfer device is disclosed, the process comprising converting a photographic film image into video signals representative of the image with a telecine transfer device which uses a cathode ray tube flying spot scanner in combination with at least one dichroic beam splitting mirror to separate the light from the cathode ray tube into component spectral segments which are then detected by a light detector, wherein a filter is positioned between the dichroic mirror and the light detector to compensate for an inconsistent spectral distribution of light in at least one component spectral segment resulting from a varying angle of incidence of light originating from various positions of the cathode ray tube onto the dichroic mirrors, said filter reducing the magnitude of the range of spectral change due to the varying angle of incidence. In preferred embodiments of the invention, the light from the cathode ray tube is separated into red, green and blue component segments. In a particularly preferred embodiment, a properly designed filter is used such that the spectral distribution of light that reaches the green component light detector results in a substantially consistent side-to-side contrast detection with various photographic film stocks. The instant invention differs from previous methods of shading correction in that the correction is being done optically instead of electronically. The optical correction is substantially film independent.

摘要： A method for previewing a scene before actual capture by a motion-picture camera for permitting improved creative control of the scene ultimately captured by the motion-picture camera, the method comprises the steps of providing a digital representation of the scene; mapping the digital representation through a transfer function which maps the digital representation to image data representative of image data that a predetermined film will create; providing the mapped image data to a display; and displaying the image data on the display.
