<p>PURPOSE:To obtain an image pickup tube for a single tube type color television camera by which uniform color sepn. characteristics are obtained with respective colors by forming the section of a green filter of a dye material having the low spectral transmittance in an IR region. CONSTITUTION:A cyan filter 7 is formed on a light transmittable glass substrate 1 in the section corresponding to the position where only the cyan stripe exists in the prior art. A yellow filter 8 is formed in the section corresponding to the position where only the yellow stripe exists in the prior art. Both kinds of these filters are not formed at all in the position corresponding to the intersected section of a cyan filter stripe 2 and a yellow filter stripe 3, and a green filter 9 is formed in said intersected section. No filters are formed in the space part 10 where the filter 7, the filter 8 and the filter 9 are formed adjacently.</p> |
