Abstract
A telecine system comprises a cathode ray tube,with a mixed phosphor,The phosphor,is composed of phosphor components each having a distinct spectral output. Primary photodetectors,are arranged to detect light from the cathode ray tube,which has been modulated by a film,and produce primary electrical signals including information about the color content of the modulated light. Secondary photodetectors 26,-26,detect unmodulated light from the cathode ray tube,and produce secondary electrical signals including information about the color content of the unmodulated light. The primary signals are divided by the secondary signals in a signal processor,to compensate for inhomogenities in the mixed phosphor
