Claims

[Claims for Utility Model Registration] (1) An interpolation calculation means for sequentially calculating and outputting print data based on line data of odd-numbered fields and even-numbered fields is provided, and a print is made by interpolating lines using the print data of this interpolation calculation means. A video printer that performs (2) The interpolation calculation means includes a first subtracter that subtracts the line data of one field from the line data of the other field, and a divider that divides the output of the first subtracter by 1/3;
an arithmetic circuit including an adder that adds the line data of the other field and the output of the divider; and a second subtracter that subtracts the output of the divider from the line data of the other field; claim 1, further comprising a switching circuit for switching and outputting the line data of the field, the output of the second subtracter, or the output of the adder as print data in response to a switching control signal. Video printer as described in section.
