Abstract
In arrangements for the frame rate upconversion of motion-picture-source video, a 60 Hz (interlaced field rate or progressive scan frame rate) television signal is converted to a form suitable for display on a variable-frame-rate high-resolution progressively-scanned monitor of the type typically associated with a computer or with a television set employing an increased frame rate. The inherent 3-2 motion picture film pulldown pattern in the source signal is changed to an equal time frame pattern, such as 3-3, 4-4, or 5-5, when the source signal is converted to a higher frame rate. This may be accomplished when the increased progressively-scanned video display frame rate is an integral multiple of the motion picture frame rate, namely 72 Hz, 96 Hz and 120 Hz.
