ABSTRACT:
A flaw detection apparatus detects a flaw formed on an object's surface based on a digital image data indicative of said object's surface as a group of plural pixels utilizing the image processing technique. An image processor is provided for detecting a direction in which each of group extends to combine a plurality of groups extending in substantially the same direction. The image processor further produces a flaw signal indicating sizes of thus combined groups.
