ABSTRACT:
A double-scanning non-interlace television receiver with a vertical aperture correction circuit for receiving an interlace television signal having alternating odd and even fields of scanned lines which are interlaced, as displayed, comprises a receiver circuit which receives the interlace television signal and which generates interlace scanning line signals for each of the fields, a visual display apparatus, a non-interlace converting circuit which converts the interlace scanning line signals for each of the fields to non-interlace scanning line signals which are displayed on the visual display apparatus, with each of the scanned lines being scanned twice, and a high frequency emphasizing circuit which emphasizes the high frequency components of the interlace scanning line signals.
