    摘要: 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 PAL 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.

    摘要: A film-to-video frame image convertor includes a 3-2 pulldown frame convertor for converting signals representing input film frame images, having a lower associated film frame image rate, to signals representing output video frame images having a higher associated video frame image rate. The output video frame images consist of genuine and simulated video frame images, which correspond to actual input film frame images and multiple input film frame images, respectively, in accordance with a 3-2 film-to-video frame pulldown. Each genuine video frame image consists of two video field images corresponding to two actual film field images from the same film frame image. Each simulated video frame image consists of two video field images corresponding to two actual film field images from different film frame images, with one of the two video field images being a duplicate of a video field image in an adjacent video frame image. Identification signals are selectively inserted into the vertical blanking interval of some of the output video frame images to identify which ones are simulated video frame images containing duplicate video field images. This allows the duplicate video field images to be identified and selectively deleted when the video frame images, having the higher associated video frame image rate, are to be reconverted to film frame images having the lower associated film frame image rate.

    摘要: An interactive high definition display system generates its own graphics display data, accepts multiple video signals and graphics display signals based upon multiple standards, and selectively produces therefrom an integrated video and graphics display featuring multiple images or compositing. The incoming video signals are decoded into their corresponding RGB signals, digitized and written into memory. The incoming and internally generated graphics display data signals are also written into memory. According to preprogrammed instructions, or interactively according to instructions received via a computer interface, an integrated, multiple image or composite display pattern with both active video and graphics display images can be generated by selecting from and arranging for display the stored video and graphics display data, and viewed on a high definition display or stored on a high definition video tape recorder.

    摘要: A digital color correction system and method provide for color correction in a film-to-video signal conversion system. Film color correction is done by correcting incoming digitized film color signals (e.g. red, green and blue) according to film color correction parameters which represent film characteristics, such as film speed, gamma, and minimum and maximum film dye density. The film color correction parameters are used to sensitometrically convert the film color signals to video color signals according to a sensitometric film model, such as the Hurter-Driffield ("HD") characteristic curve. Video color correction is then performed upon the corrected film color signals according to video color correction parameters which represent video signal characteristics, such as hue and saturation, as well as a video color standard model, such as SMPTE 240M. Alternatively, separate signals representing the film or video color correction parameters can be encoded as separate data into the corrected or uncorrected color signals. This color correction or color correction parameter encoding can be done on a field-by-field, frame-by-frame or scene-by-scene basis, so that each resulting video field, frame or scene, respectively, is appropriately color corrected or contains its own specific color correction information.

    摘要: An operator input subsystem and an image signal processing subsystem are provided to a digital image processing system. The operator input subsystem comprises a CPU, a display device and an input device, whereas the image signal processing subsystem comprises a digital signal processor having a number of digitized signal correctors. For cases where the output results are expressible as smoothly differentiable continuous functions of the digitized input signal values and the processing parameters, the CPU receives the specified output results from the input device and the digitized input signal values and the current processing parameters from the digitized signal correctors. In response, the CPU determines the most optimal processing parameters for the digitized signal correctors to achieve the specified output results. The CPU provides the determined optimal processing parameters to the digitized signal correctors, which in turn use the parameters to correct the digitized signals. The CPU makes the determination by performing a standard non-linear optimization of the smoothly differentiable continuous function. As a result, the increasingly difficult task of providing processing parameters to the image signal correctors is done automatically for the operator, thereby making the image processing system more efficient and user friendly.
