ABSTRACT:
An automatic article sorting apparatus sorts out articles by their sizes. The apparatus includes a conveyor mechanism for conveying the articles, and an image pickup unit for producing images of the articles as they are conveyed by the conveyor mechanism. An image memory stores the images of the articles one frame at a time, and a sorting device masks an unnecessary portion of the image of an article. The size of the article is derived from the number of pixels in the unmasked portion of the image of the article, and the size of the article is compared with a preset range of grades to produce selection information. A sorting apparatus sorts out the article in accordance with the selection information.
