An image processing apparatus of this invention reads raster-scanning type binary image data, and causes an outline extraction unit to extract outline vectors of an image. When a white raster detection unit detects that one raster data consists of all white pixels, it supplies the detection result to the outline extraction unit. Upon reception of this detection result, the outline extraction unit outputs the outline vectors extracted so far as a group of data to an outline smoothing & enlarging/compressing unit as a processing unit for executing outline smoothing processing or enlarging/compressing processing. In this manner, since this invention processes an image as a group of data divided in units of white rasters, advantages such as a decrease in required memory capacity can be expected. <IMAGE> |
