PROBLEM TO BE SOLVED: To obtain dynamic characteristic measurement data when an animation is displayed on a plasma display panel (PDP), SOLUTION: When an image, which moves along the scanning line direction of a screen, is displayed on the screen of a PDP 2, light signals of few scanning lines of the screen of the PDP 2 are made incident on a line sensor through a photographing lens of an image detecting device 3. The incident light signals are converted into electric signals by the line sensor and accumulated. When vertical synchronization signals that are delayed by a prescribed amount by an image signal generator 1 are outputted to the device 3 in response to the image control signals from a control device/computing device 4, image reading signals are generated by a timing signal generating section in synchronism with the vertical synchronization signals, analog image signals are taken out from the line sensor by the generated image reading signals, converted into digital image signals and supplied to the device 4.
