ABSTRACT:
An outline extraction method and apparatus which extracts a line of interest from image data in order of raster scanning and detects outline vectors of the pixels in the line of interest. The detected outline vectors are sequentially stored in a memory, a state of connection between the stored outline vectors and the other outline vectors in the line of interest is determined, and the outline of the image data is extracted based on the state. Accordingly, coordinates of an intersecting point of the outline of the image data with the coordinate axis of the outline vector is obtained and the image data is coded by generating coded data indicating a white run length and black run length for every line from the coordinates of the intersecting point.
