PURPOSE:To reduce the number of A/D converters and the capacity of memories by providing a single A/D conversion means which converts two different color difference signals in a field sequence from an analog to a digital form and two field memories in which the output from this A/D converter is written by fields. CONSTITUTION:A single A/D conversion means 6 is provided which converts two different kinds of color difference signal converted from a color signal in a field sequence from an analog to a digital form. In addition, field memories 8, 9 are provided which the output from the A/D converter 6 for A/D conversion is written in by field. Consequently, it is possible to reduce the number of A/D conversion means 6 and the capacity of field memories 8, 9 respectively as well as manufacture a video printer at low cost. |
