Abstract
A system for detecting blemishes on an illuminted object, such as the screen of a kinescope, includes a charge coupled device (CCD). The signal from each CCD pixel is compared with the average of the signals of all pixels immediately adjacent to the pixel being investigated to provide a difference signal. The difference signal is compared to a threshold level and a blemish signal generated when the difference signal exceeds the threshold.
