摘要： Field information for a predetermined number of fields produced by another field judgment circuit is stored in a first memory. The output of the field decision circuit which is indicative of the field information for the predetermined number of fields is stored in a second memory. The contents of the first memory are compared with those of the second memory. When the contents of the first memory disagree with the contents of the second memory for all of the predetermined number of fields, the field information is output as the field information from the field decision circuit.
