ABSTRACT:
A video printing apparatus for forming color separation films and a color film recording an image of a video signal of a desired frame is disclosed. The video signal is once recorded on a 1" video tape together with time codes denoting respective frames. The video signal of the extracted frame is processed by time error corrector, a noise reducer and a detail corrector and then the thus corrected video signal is converted into R, G, B signals which are then stored in frame memories. The color signals stored in the frame memories are successively read out and are supplied to an interpolator composed of a hard logic circuit to produce interpolated color signals composed of a great number of scanning lines. The interpolation can be effected by one of cubic convolution, bilinear and nearest neighbor methods in dependence upon a kind of the image to be interpolated. The interpolated color signals are supplied to an electronic color scanner for forming cyan, magenta, yellow and black color separation films. The interpolated color signals are supplied to a color photography unit in which successive color signals are displayed on a flying spot scanner tube and displayed images are projected onto a color photographic film by means of red, green and blue color filters, respectively. The color signals are read out of the frame memories at timings corresponding to scanning speeds of the color scanner and the color photography unit.
