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 includes interpolation and double-rate translation in the luminance channel and double-rate translation only in the chrominance channel. In one embodiment the two-times translation (each line repeated) is applied to the chrominance channel after separation from the luminance but prior to demodulation. In another embodiment the chrominance signal is two-times translated prior to demodulation thus requiring demodulation after double-rate translation. |
