  • Publication number: 20080232683
    Abstract: An image processing apparatus includes a first separator, a second separator, a dividing unit, and a generating unit. The first separator separates image data into character image data and other image data. The second separator separates the character image data into shape image data and color image data. The dividing unit divides the shape image data and the color image data based on a dividing size decided from the size of the image data and the capacity of processing memory used in output processing of the image data. The generating unit generates additional information for combining a corresponding pair of divided shape image data and divided color image data with the other image data.
