Title: Television display correction
Inventor: FREEMAN KENNETH GEORGE
IPC: H04N3/233
Filed: 1981-07-08
Abstract: To correct vertical distortion on a CRT, with large angle or flat screen, a field frequency sawtooth from generator 1 is added to a correction waveform, the sum signals being converted 3 into deflection current through coil 4, producing a pre- distorted deflection field. The correction is derived from digital data in RAM's 5 and 12, converted to analogue 10, 13 and interpolated at line and field rate by an interpolator 14 feeding adder 2. Generator 7 receives field and line synch inputs from 6, 8 and generates addresses applied via multiplexer 9 to RAM 5 and via adder 11, which adds a binary '0' to the address code, to the RAM 12. The data read from RAM 5 relates to the field direction errors across the display row-by-row, while that read from RAM 12 relates to the row below that read from RAM 5. The error information is previously loaded into the RAM's 5 and 12 from data input 32 with the addresses being applied through input 31 to the multiplexer 9, the circuit having previously been set for load operation via control input 30. A similar circuit may be used for errors in the horizontal direction.   <IMAGE>
