Abstract

PURPOSE: To decrease the amount of data by encoding and storing digital data, converted by using dummy gradations method for one pixel of an analog video signal, and decoding the data at print time. CONSTITUTION: To convert an analog video signal 9 of a CRT display, a video camera, etc., into digital data for dummy gradations and print the data, the digital data and an encoded data generator 8 are used, the digital data is used as a write enable signal to a memory 3 which stores image data, and the output of the encoded data generator 8 is written as the digital data in the memory. Then the analog video signal 9 is converted into encoded digital data, which are read out and decoded at printing time, so that the data are printed. Consequently, the amount of data can be reduced without decreasing the amount of information that the data have.
