Abstract:
An apparatus for inspecting an image of an image displaying apparatus, comprising:a pattern generator provided with a pattern signal generating part generating an inspection pattern signal and a pattern frame synchronizing signal generating part generating a pattern frame synchronizing signal and displaying an inspection pattern on the image displaying apparatus according to the inspection pattern signal and pattern frame synchronizing signal; a camera provided with an image frame synchronizing signal generating part generating an image frame synchronizing signal, grabbing the inspection pattern displayed on the image displaying apparatus according to the image frame synchronizing signal; a phase selecting part selecting a random phase point of the pattern frame synchronizing signal generated by the pattern frame synchronizing signal generating part; and a V-sync signal synchronizing part synchronizing a first signal among the image frame synchronizing signals generated by the image frame synchronizing signal generating part with the phase point selected in the phase selecting part.
