    • PURPOSE: An apparatus for measuring image quality is provided to easily realize a full reference without additional distortion which can occur during a data obtaining process. CONSTITUTION: An original image storage unit(10) stores an original image. The first capture board(72) receives a signal outputted from the original image storage unit. The second capture board(74) receives a signal outputted from the original image storage unit through an image terminal encoder, a transmission medium, and an image terminal decoder. An NTSC(National Television System Committee) converter(20) converts a VGA(Video Graphics Array) signal outputted from the original image storage unit into a composite signal. The NTSC converter inputs the composite signal to the first capture board and the image terminal encoder.
