ABSTRACT:
Television (TV) scanning with improved resolution is obtained by implementation into a conventional TV scanning arrangement of a vertical drive signal modifying circuit which modifies vertical drive signals prior to their being provided as an input to the conventional TV scanning arrangement. Processing of the vertical drive signals results in the generation of various time delay signals which, when logically combined in accordance with the present invention, result in the generation of modified vertical drive signals. As a result of application of the modified vertical drive signals to the conventional TV scanner arrangement, the number of fields making up the conventional interlace pattern is multiplied by an integral factor greater than one.
