Abstract
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 progressive scanned image is formed from 'real' and interpolated lines of luminance. In this arrangement the interpolated line is formed by weighting samples from time-successive lines. To improve the vertical detail of a progressively scanned image vertical detail information which may be obtained from the chrominance channel is combined with both 'real' and interpolated lines, or one to the exclusion of the other, to enhance the image displayed.
