Abstract
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.

A method for storing information for converting a video originated image into data representative of a modified video image simulating an image originated from a photographic film stock, comprising: producing digital data representative of the color component response of a selected photographic film stock under a selected group of photographic variables to selected photographic subject colors; storing said digital data in a memory for use in modifying each pixel in the video originated image to simulate each corresponding pixel of an image originated from photographic film stock; and correlating data groupings derived from video originated image material with said digital data representative of the color component response of a selected photographic film stock, said data groupings representing color component responses of a selected video source to a selected videographic subject color under a selected number of videographic variables.
Claim 89
Dependent Claim
43 words
The method claimed in claim 80, further wherein: said step of storing digital data representative of the color component response of a selected photographic film stock comprises storing data to which selected data groupings of said video originated color component responses is modified.
Claim 90
Dependent Claim
47 words
The method of claim 80, further wherein: said step of storing comprises storing said information as said digital data defining a selected film stock's selectively detailed color component response range as data able to be referenced against a selected video source's selectively detailed color component response range.
Claim 91
Dependent Claim
143 words
Apparatus for storing information for converting a video originated image into data representative of a modified video image simulating an image originated from a photographic film stock, comprising: means for producing digital data representative of the color component response of a selected photographic film stock under a selected group of photographic variables to selected photographic subject colors; means for storing said digital data in a memory for use in modifying each pixel in the video originated image to simulate each corresponding pixel of an image originated from photographic film stock; and means for correlating data groupings derived from video originated image material with said digital data representative of the color component response of a selected photographic film stock, said data groupings representing color component responses of a selected video source to a selected videographic subject color under a selected number of videographic variables.
Claim 92
