<p>An interline transfer CCD imaging apparatus in which a rectangular array of photoelectric elements create and store charges which are then shifted vertically by a set of vertical CCD registers to a horizontal CCD register has a corresponding array of color filters in front of the photoelectric elements. The color filters are arranged so that two picture elements form one cycle horizontally, and four picture elements formone cycle vertically. From left to right in the first and fifth rows 11 and 15, cyan Cy min and yellow Ye filters are repeated. In rows 12 and 16 magenta Mg min , and green G min filters are repeated. In rows 14 and 16 the magenta Mg min and Green G min filters are repeated in the opposite order. The cyan Cy min filter transmits green, blue and red light, the red transmission being about 50%. The yellow Ye filter transmits green and red light but not blue. It is arranged that the NTSC color difference signal for rows 11, 13, 15 and 17 is zero at a reference color temperature for achromatic light. The green G min filter is formed by laminating a cyan Cy min and a yellow Ye filter together. The magenta Mg min filter transmits a higher percentage of green light than in the prior art, and it is arranged that the NTSC color difference signal for rows 12, 14, 16 and 18 is zero at the chosen reference color temperature for achromatic light. </p> |
