Abstract: A multi-touch input processing method performed by a multi-touch input device and a multi-touch recognition apparatus, the method including: recognizing a touch input from at least one input device; connecting the at least one input device via a radio communication; receiving touch input data from the at least one input device; and executing an application based on the touch input and the touch input data. The apparatus includes a multi-touch processing unit for recognizing a touch input from at least one input device; a radio communicating unit for connecting the at least one input device with the multi-touch processing unit via a radio communication; a touch input data receiving unit for receiving touch input data from the at least one input device, and an application executing unit for executing an application based on the touch input and the touch input data.

Abstract: Provided are a method and apparatus for processing image data in a printer, in which page description language (PDL) data is analyzed and generated as standard color data, the generated standard color data is converted to a plurality of printer outputting colors, image conversion processes are parallely performed on the printer outputting colors, and printing data is generated on a page-by-page basis based on the printer outputting colors to which the image conversion processes are performed.
