Abstract
The image processing device converts input image data into converted data. A two way buffer in the image processing device stores reference data generated by a converted data generator under the direction of a controller. The two way buffer is then used to generate converted data in response to received image data. Also, depending upon the input device connected to the image processing device, a selector selects one of a plurality of processing characteristics. The selected processing characteristics are used to vary and set a conversion function for converting the image data to produce the converted data.
