Abstract

PURPOSE:To perfectly eliminate the shift of the luminescent material impulse timing and the chrominance signal impression timing of a beam by newly substituting the memory data when the light receiving quantity of a detection means becomes the greatest by increasing and decreasing the memory data in a proper extent for data in a memory means. CONSTITUTION:An index signal and a beam position signal are obtained from the emission of a luminescent material and the phase difference between the both signals is measured and stored in a memory 61 as the digital data 1. Then the data 1 is digitally changed one by one by a personal computer 68, the emission at each time is received and amplified by a photoelectric conversion element 56. After that, the peak value of a light receiving signal is held as a direct current value by a peak holding circuit 66, digital-converted by an A/D coverter 67 and read by the personal computer 68. Besides, the data when the peak value becomes the greatest is searched by the program of the personal computer 68 and that data is substituted for the data 1 in the memory 61. Thus the correct chrominance signal impression timing is stored.
