1. An image processing device for subjecting photo-electrically read-out image data received from an image reading unit to a predetermined image processing and for recording the read-out image data, comprising:

  • a plurality of memories for storing the image data read out by the image reading unit;

    an image processing unit for reading the image data from said memories, wherein the image processing unit reads one or more lines of image data from a single frame of an image stored in said plurality of memories to perform predetermined processing of said one or more lines of image data by pipeline processing;

    a condition setting unit for setting image processing conditions in said image processing unit;

    an image data bus for inputting and outputting the image data; and

    a control bus for inputting and outputting control data,wherein the image processing unit and the plurality of memories provide for simultaneous reading out and image processing of image data, due to the image processing unit reading one or more lines of image data from a single frame of an image stored in said plurality of memories, and due to at least one of said plurality of memories having an empty or writeable area to receive a subsequent frame of image data from the image reading unit.
