US Patent 7558443 Camera system with real-time dithering and printing capabilities

A camera system includes an image sensor configured to capture an image. A memory is coupled to the image sensor and is configured to store the captured image. A printhead interface is coupled to the memory, and is configured to take a planarized linear image obtained from the stored image and produce a dithered image in real-time. A printhead is coupled to, and controlled by, the printhead interface to print the dithered image. An ink supply is provided in fluid communication with the printhead and supplies a plurality of colored inks to the printhead for printing.
