Abstract: An inspection device includes an imaging unit which captures an inspection target and outputs image data corresponding to the inspection target, a data extraction unit which receives the image data and extracts inspection data corresponding to an inspection area of the inspection target from the image data, a setting unit which sets a threshold value based on a grayscale value of comparative data compared with the inspection data, and an inspection unit which determines whether the inspection target is defective based on the threshold value.
