Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To attain high speed image processing by labelling a noticeable picture element based on comparison with plural adjacent picture elements, generating virtually a background picture element when no adjacent picture element is in existence and labelling all picture elements under the same condition to reduce the labelling processing time. SOLUTION: In the case of conducting labelling processing by comparing a noticeable picture element W with two picture elements P, Q, since the compared picture elements P, Q are in existence in a part within an area D, the noticeable picture element W is labelled. However, both the picture elements P, Q are not in existence in an area A, the picture element P is not in existence in an area B, the picture element Q is not in existence in an area C, and no image is in existence at the outside of the areas A to C, then a background image is virtually generated at the outside of the areas in order to make label discrimination with the same condition as the area D. Thus, it is not required to make area division and label discrimination for each area and then the processing time is reduced.
