Abstract:
A moving picture format conversion apparatus for converting a first interlaced video signal of a first number of scanning lines into a second interlaced video signal of a second number of scanning lines, the first and second numbers being different from each other, the apparatus comprising:a progressive video converter to convert the first interlaced video signal into a first progressive video signal by interpolating the first interlaced video signal with scanning lines which have been decimated from the first interlaced video signal, the first progressive video signal having the first number of scanning lines identical to the first number of scanning lines for the first interlaced video signal at a frame rate identical to a field rate for the first interlaced video signal; a scanning line converter to convert the first number of scanning lines of the first progressive video signal into the second number of scanning lines by re-sampling, to generate a second progressive video signal of the second number of scanning lines; and an interlaced video converter to convert the second progressive video signal into the second interlaced video signal by decimating the second number of scanning lines of the second progressive video signal, the second interlaced video signal having the second number of scanning lines identical to the second number of scanning lines for the second progressive video signal at a field rate identical to a frame rate for the second progressive video signal.
