The color synchronization device comprising: an A/D converter that A/D converts the input signal of each field and outputs digital data of both color difference signals alternately for each line; and each of the A/D converters. The output data of the field is alternately supplied line by line, and the digital data of each of the two color difference signals of the color image of at least one frame is written, and each written data is changed to zero the data of the missing line. Two color difference data memories each having a capacity of one field or more are read out in line order in non-interlaced scanning, and each of the two color difference signals is processed by interpolation between lines within a frame based on one frame of read data from each of the two memories. two synchronization circuits that generate the data of the missing line from at least the data of the line immediately before or after the line; and the output data of the two synchronization circuits are respectively
Two D signals that A-convert and reconstruct the two color difference signals.
/A converter.
