Abstract

PURPOSE:To secure the accurate interlace by presetting the different initial value input of the saw-tooth wave generating counter or the A/D converter alternately with every field. CONSTITUTION:Identification 25 is given between one field and the other in the same frame with the change of the rise time of the horizontal synchronous pulse near the rise time of the vertical synchronous signal in the synchronous signals. Then the different initial value input are preset to the input of D/A converter 43 which is connected to the input or the output of counters 41 and 42 according to the output of the field identification and alternately with every field. Thus the saw-tooth wave signal are obtained with the different average value alternately with every field. In this way, the accurate interlace can be carried out.
