摘要

A flat-field television image having reduced visibility of horizontal scan lines is generated by receiving first and second fields of interlaced video and progressively generating a scanned image within a time for one incoming field. The progressively scanned image contains interstitital lines between the lines of one field, and consequently the line-scan structure is made less visible, but the flicker rate is undesirably decreased. In order to increase the flicker rate, additional progressively scanned images are generated at a rate equal to or greater than the incoming field rate.
