Abstract
A video signal processor for effecting frame rate conversion. A number of framestores connected in series receive incoming video signals under the control of a first generator and are available from the respective fieldstores under the control of a second generator. The presence of respective one line delays allow two adjacent lines from the same field to be available for use by respective multipliers and thence to an adder. A comparator determines if significant movement is present and modifies co-efficients to the multipliers, made available from a co-efficient control so as to allow a single field to pass to the output if desired.
