Abstract
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.
