Abstract

PURPOSE: To make it possible to detect surely a position, where an index fluorescent substance stripe is omitted, even for reproducing of single color by gating three- primary color signals in respective fluorescent substance stripe positions and thier middle positions.
CONSTITUTION: Index fluorescent substance stripes I are formed at the ratio of three to two sets of color fluorescent substance stripes R, G and B, and stripes I are omitted at the ratio of six to one. Output signals of photo detector 20 are supplied to BPF21 to obtain index signal SIH. This signal is supplied to PLL23 to obtain signal PL of a frequency twice as high as the frequency of signal SIH, and signal PL is supplied to gate pulse generator 30. Meanwhile, signal SIL from BPF22 and signal SIH are supplied to mode set pulse generator 70 to obtain mode set pulse PS which is obtained at a fixed position for the position where stripe I is omitted, and this pulse PS controls generator 30. As the result, signals FR, FG and FB which gate stripes R, G and B and their middle positions are obtained and gate three-primary color signals.
