Abstract
A film scanning system and method for generating a digital signal representing digitized film images, and having a first (less than real-time) film frame rate, and performing digital correction (such as flare correction, color correction, or both) on the digital signal at a higher (but still less than real-time) frame rate. In a preferred embodiment, conventional video signals (having NTSC or format, or SMPTE-240M or another high definition video format) are then generated from the corrected digital signal. In one embodiment, the system of the invention includes circuitry for scanning color film frames to generate and store a digital signal (representing digitized color film images) at a rate of 1.875 film frames per second, circuitry for color correcting the stored digital signal at an internal processing rate of 7.5 frames per second, and means for generating SMPTE-240M high definition video signals (having a frame rate of 30 frames per second) from the color corrected digital signal.
