Inspection device, inspection method, the inspection system, a method for producing a color filter, test apparatus control program, and a computer readable recording medium storing the program
An inspection device of the present invention includes: a linear irregularity detecting section for detecting linear irregularities individually in an image L of dots on a substrate being inspected by projecting light from a first direction and in an image R of the dots by projecting light from a second direction, which differs from the first direction; a specific-cycle irregularity extracting section for extracting linear irregularities detected at predetermined intervals T in the individual mages L and R, the intervals being taken vertical to the linear irregularities on the substrate; and a detection-target-irregularity extracting section for extracting a linear irregularity detected in both the images L and R as a detection-target linear irregularity. The device therefore is capable of detecting only linear irregularities of a specific cycle which are caused by the presence of dots having irregular thickness when compared to a dot with normal thickness.
