PURPOSE:To increase a transfer speed and to reduce recording capacity by recording only the necessary min amount of matrix data, by selecting only the data during an unblank signal generating period among the data read from an image digital memory. CONSTITUTION:An Lo decremental counter 16d starts decremental counting from Lo(dot) in the timing of the start row of one line. When the output Lx of a PROM(3)16b is coincides with the output of the Lo decremental counter 16d, the reversal output Q of a flip-flop 16e becomes active. At this time, a 2Lx decremental counter 16f starts the decremental counting of 2L(dot) and, when 2Lx(dot counting) is finished, the output of the 2Lx decremental counter 16f is inputted to the flop-flop 16e and the reversal output Q becomes inactive. By this method, an unblank signal is formed at every one line and data is sent to an image recording apparatus 18 to be recorded. In the image recording apparatus 18, the recording/regeneration of data is performed only during a period when the unblank signal is active. |
