Abstract
A method and apparatus for detecting and removing unstripped residual shell left on shellfish. This method and apparatus are characterized by irradiating a light of specific wave-range onto stripped shellfish after finishing the shell-stripping work thereof. A CCD camera is used to examine the shellfish. It is then determined if there is residual shell on the stripped shellfish on the basis of information on the intensity of fluorescent light that can be obtained from the image taken by the CCD camera. Any shell is then removed.
