Patent ID: 7933049

Claim:
A multifunction printer having a first function of copying an image original and a second function of transferring image data obtained by scanning the image original to an external device (PC), comprising: reading means configured to line-sequentially read the image original to obtain uncompressed image data; a memory; first image processing means configured to execute a shading process and a compressing process for the image data; transfer means configured to transfer the image data from said reading means to said memory means via said first image processing means when the first function of copying an image original is executed, such that shaded and compressed image data is transferred to said memory, and to transfer the image data from said reading means to said memory without shading and compression by said first image processing means when the second function of transferring image data obtained by scanning is executed; second image processing means configured to decompress compressed image data read from said memory when the first function is executed, and to execute a shading process for uncompressed image data read from said memory when the second function is executed; and filtering means configured to execute a filtering process for the image data processed by said second image processing means.
