First example (b) shows that an R(red) signal is weak and no large difference exists between a G(green) signal and a B(blue) signal, and a considerable difference exists between the R signal. At such a state, the luminescent position is not irradiated with a read beam.

Third example (d) shows that the fluorescent material dot is irradiated with the external light brightly considerably, however, it is not irradiated with the electron beam. Only when the difference (a) between the maximum chrominance signal and the minimum chrominance signal exceeds a prescribed value, it is assumed that light is emitted by receiving electronic irradiation.
