ABSTRACT:
A system controller (102) is for generating a compressed facsimile message in a radio communications system (100). The system controller (102) includes an image memory (203) for storing an optical image, means for image analysis (205), means for best scan angle identification (204), an image rotator (220), and a facsimile encoder (225). The means for image analysis (205) generates a long line analysis of a portion of the stored optical image using a scan angle. The means for best scan angle identification (204) identifies a best scan angle from one or more image analyses generated by the image analysis means (205). The image rotator (220) generates an aligned optical image by using the stored optical image and the best scan angle. The facsimile encoder (225) generates the compressed facsimile message from the aligned optical image.
