A capacitor element is provided which is composed of a lower electrode, an upper electrode formed in opposing relation to the lower electrode, and a capacitor dielectric film made of a ferroelectric material or a high dielectric material and formed between the lower and upper electrodes. The hardware-simulating program can be recorded in any suitable recording medium and defines therein a plurality of simulating elements which are automatically synchronized at intervals by setting specified time points as aligning points. The surface of a light source is scanned by a knife-edge and the light ray start position on the light source is determined depending on the interception of the light ray by the knife-edge or the de-interception of the light ray, thereby learning the start position of the detected light ray on the light source.
