ABSTRACT:
A photo-printing system includes a laser exposure unit, a reference clock generation unit, an image input unit, and a controller. The image input unit receives first pixel data and second pixel data to be expressed after the first pixel in accordance with image data. In a first control, the first and second pixels are scanned for exposure in a laser emission region state wherein each of the scan-start timings of the first and second pixels are controlled in accordance with a reference clock. In a second control, the first pixel is scanned for exposure in a nonlinear light emission region state, and the second pixel having a density equal to or lower than a predetermined density is scanned for exposure in the laser emission region state, the scan-start timing of the second pixel is advanced with respect to the first control.
