Abstract: PURPOSE:To shorten and simplify an outline extracting process and to discriminate between 'ground' and 'figure' at the same time by adding image data having the same pixel value 'figure' (white) of one-dot width outside the periphery of an image. CONSTITUTION:The pixel data 3 having the same pixel value (white) with 'figure' of one-dot width are added outside the periphery of the object image. When an interesting pixel is 'figure' (white), adjacent pixels are checked. When four-connection outline extraction is performed at this time, eight pixels adjoining to the periphery of the interesting pixel 7 are checked and when eight- connection outline extraction is performed, four upper and lower, and right and left adjacent pixels of the interesting pixel 7 are checked; when those pixels are all 'figure' (white), a flag is set for the pixel value of the interesting pixel. Consequently, only pixels which are not flagged and has white output data are displayed to extract and display the outline and at the same time, whether pixels other than the outline are 'ground' or 'figure' can be discriminated.
