Abstract

PURPOSE:To obtain a color resolution filter whose color resolution characteristic is approximate to an ideal image pickup characteristic of the NTSC system, by reducing the transmittance of a filter for transmitting a trichromatic light, in a pertial area of a transmission color light band of a filter for transmitting a dichromatic light. CONSTITUTION:Magenta stripes 3a-3c are stuck between parallel cyanic stripes 1a-1c, respectively. Yellow stripes 2a-2c are made to adhere onto the upper surface of these stripe groups 1 and 3. The spectral transmittivity of areas F11, F12, F13, and F14, becomes curves I1, I2, I3 and I4, respectively, and it is possible to obtain a color resolution filter whose color resolution characteristic is approximate to an ideal image pickup characteristic of the NTSC system.
