PURPOSE:To prevent distortion of an image due to line lacking by detecting a moving-speed error at its occurring, and applying correction to an image data. CONSTITUTION:At the starting time of inputting an image, zero is set in a raster number counter 4. A line sensor 1 at all time repeats reading of one-line- share of data. After an input probe 6 starts to move, a moving detection part 3 outputs moving pulses at a rate one for every moving for a distance that meets the resolution in the subscanning direction. The raster number counter 4 counts up by one by a piece of moving pulse, and turns to be in state '1' from '0'. This means that the data in the first line is currently being transmitted. If a moving-speed error occurrs, in case, for instance, the input probe 6 moves for a 2-line-length of distance at the time of reading one line, the counter 4 counts up by two. |
