PURPOSE:To simplify a system, by loading a gamma table on a high speed memory from a read only memory by judgement of a central control part. CONSTITUTION:A compound video signal is separated into a horizontal synchronizing signal and a vertical synchronozing signal. The three primary colors are reproduced from this compound video signal and digital signalized. Then, the digital signal output is gamma converted. Thereafter, before a still image video signal is hard copied, gamma conversion as well as data sampling of one line are carried out with a high speed memory in which the gamma table stored in this read only memory is loaded. Then, data are written directly into a digital data processing part processed by print data and printing is carried out. Thus, the system can be simplified. |
