ABSTRACT:
An apparatus for converting a negative image on a negative recording medium to a positive image includes a first converter for converting a composite video signal into its luminance and color difference components. A first processor electronically inverts the luminance signal while a second processor electronically inverts the luminance and color difference components together resulting in second luminance and second color difference signals. The second luminance and second color difference signals are encoded to produce a second video signal which is a positive image having corrected brightness and white balance.
