ABSTRACT:
Laser imaging apparatus includes a laser which produces a laser beam. An image media is scanned with a laser beam in a raster pattern to produce a scanned image. A photodetector converts the scanned image into an image signal. An amplifier amplifies the image signal and has varying gain. A control circuit controls the laser beam scanning device to scan image media of different sizes with laser beam raster patterns of different sizes. The control circuit includes detectors for detecting the size of the image media. The control circuit varies the gain of the amplifier as a function of the detected size of the scanned image media.
