摘要

When recognizing leads by processing an image captured by a camera of a component provided with a single row or multiple rows of leads of the same size and shape at a regular pitch, waveform analysis of a change pattern of brightness (pixel value) along multiple lines set in a vertical, a horizontal, or a diagonal direction of the image is performed so as to identify a region in which the brightness changes cyclically as a lead recognition target region in which there is a possibility of a lead existing. Then, image recognition of leads is performed in the lead recognition target region. By this, even in cases in which there are metal portions or the like that are easily confusable with leads in a region outside the lead recognition target region, the mis-recognition of these metal portions or the like as leads is prevented, thus the recognition accuracy of leads is improved.
