ABSTRACT:
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. The revised digital data is assembled and converted to an analog signal for a secondary modification wherein: 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. An automatically variable filter over the projector lens compensates to maintain the same brightness result from the opposite side of the film surface. A precisely aligned, compatible high definition camera unit provides a synching signal to the projector and automatically frames and focuses on the projected image from the reverse side of the celluloid surface, scanning the projected scan lines, to output the grain-embodying image for recording and displaying on a high definition format or external conversation to NTSC for broadcast purposes.
