Abstract
An apparatus and a method for inspecting an image, synchronizing a pattern frame synchronizing signal and an image frame synchronizing signal to initiate grabbing an inspection pattern, where the pattern frame synchronizing signal and the image frame synchronizing signal have different frequencies. With this configuration, where the frequencies of the pattern frame synchronizing signal and the image frame synchronizing signal are not identical, since grabbing an image of the inspection pattern is initiated by synchronizing the image frame synchronizing signal with the pattern frame synchronizing signal, the noise inserted into the image of the inspection pattern becomes regular, thereby resulting in enhancing the reliability of the image inspection.
