PURPOSE:To make the picture deterioration of the joint between recording dots of each scanning difficult to be observed, by making the end edge of the dot line capable of being formed by one scanning do not agree with the end edge of the dot line capable of being formed by other scanning. CONSTITUTION:The first stage data are successively sent from a picture memory 1. When the transfer of data is completed, a pulse is sent to a recording stage counter 6 from a timing clock generation circuit 1 and the second stage data are successively sent from the picture memory 2. The output of counter 6 is inputted into a random number generator 7. The random number generator 7 is synchronized with the timing from the clock generator 1 and sends alternative value of two or three data to a data selector 3. The data selector 3 distributes the data from the memory 2 to 0, 1, 2 of the buffer 4 according to this signal and make them be memorized. |
