A digital color correction system and method for correcting a color video signal representing a portion of a colored optical image by modifying the entire color space of each of the complementary colors which make up the color signal so that all objects which contain each color are modified at once. A correction means produces an output video signal having a plurality of complementary color components, each of which is related to a corresponding color component of the color video signal by a transfer function, and a modification means for independently modifying each of the transfer functions is provided. The entire color space for each color may be modified, or only selected portions of it. Thus, only objects falling within a desired range of the color space may be selectively modified.

Digital color correction system having gross and fine adjustment modes

A computerized interactive menu-driven video signal processing apparatus and method for selectively converting and processing color video signals from a color film scanner includes and provides a method for using a film scanner, a video color signal processor, a video signal storage device (e.g. high definition video tape recorder) and a computer with an interactive menu-driven operator control interface. The operator interface includes an alphanumeric keypad, a computer 'mouse,' a graphics display and a video monitor. While viewing analytical data (e.g. film masking coefficients, model film dye characteristic curves) on the graphics display and video images on the video monitor, the operator enters data and commands into the computer via the alphanumeric keypad or mouse to control the film scanner, the video color signal processor and the video signal storage device. Thus, the operator can precisely and interactively control every aspect of the video conversion and signal processing, including the scanning of the film, the actual video signal processing, and the storage and retrieval of the selectively processed video.

Computerized interactive menu-driven video signal processing apparatus

A method and system for generating icon displays representing digitized film scenes and scene processing operations, and manipulating the icon displays to initiate selected processing operations (such as transfers from one storage location to another) on the scenes. The invention can be embodied in a film scanning system having circuitry for digitizing scanned film images, for digitally correcting the digitized scanned images, and for inserting video sync information into the corrected images to convert the corrected images into a video signal. The system is also capable of inserting digital data in such a video signal, such as film in and out points, and data identifying a video storage location, and then storing the resulting video signal as a video format scene. In addition to generating a scene from a sequence of digitized film frames and related digital data, the system of the invention generates an icon representing the scene by compressing a selected one of the frames in the sequence. In response to a user command for information regarding a scene, the system displays the compressed scene image and other relevant scene data. The system also displays scene processing icons. In response to user selection of a scene icon and a scene processing icon, the system executes the corresponding processing operation on the corresponding scene.
