<p>PURPOSE:To output signals with good S/N from an impage pickup tube by inserting the filter filaments of the specified spectral sensitivity characteristics between the filter filaments for three primary colors arrayed in the specified order. CONSTITUTION:The color separating stripe-form filter is reiteratively arrayed with the filter filaments F1 which allow the passage of any one primary color of three primary colors, the filter filaments F2 which allow the passage of the other one primary color other than said primary color and the filter filaments F3 which allow the transmission of white light in the specified order. The filter filaments F4... of the spectral sensitivity characteristic which do not allow the transmission of black color light or of the same spectral sensitivity characteristic to any one of the filaments F1-F3 are provided between the filaments F1, F2, F3. Hence, the amplitude of the secondary higher harmonic components used for the generation of the three primary color signals of color demodulation out of the higher component signals in the image pickup output signals is made larger compared with the fundamental wave component, whereby the image pickup signals of good S/N may be outputted with good efficiency.</p> |
