Abstract: A copier transforms an original image into M copies in N formats. The copier has an image capturing module, an image processing module, an error diffusion module, a render & control module, an image output device, an image compressor, a memory, a data de-compressor, and a processor for controlling the image capturing module, the image processing module, the error diffusion module and the image outputting device, and for controlling the image compressor, the memory and the data de-compressor by determining M, N, and the size of a compressed image from the original image by the image compressor.

Abstract: A system and method for calibrating sizes of scanned images automatically. The method includes scanning a reference chart, generating a calibration parameter according to the number of scanned pixels obtained in the scanning and the expected number of pixels of the reference chart, and adjusting the sizes of scanned documents according to the calibration parameter.
