<p>An array of picture elements in rows l 1, l 2, etc provides inputs to vertical charge coupled device (CCD) registers which feed into a horizontal CCD register which provides the video output. In even fields transfers are made from even rows l 2, l 4, etc and then, after a one element shift from odd rows l 1, l 3, etc so that combined signals l 2, + l 3 + l 4, etc are formed.
<??>Similarly in even fields the combined signals are l 2 + l 3, l 4 + l 5, etc. The elements have colour filters establishing a 2-element horizontal by 4-element vertical repeat pattern wherein a green component comes from all elements whereas red and blue components are modulated at a 2-element horizontal rate with a line to line phase alternation applying to these components, but not the other. In accordance with the invention the said pattern is established using transparent (W), green (G), yellow (Ye) and cyan (Cy) filters, where transparent passes all components, yellow passes red and green and cyan passes blue and green.
<??>Every row has at least one filter passing red and at least one passing blue within each 2 by 4 pattern block but the modulation of red and blue is retained as red components pass only alternate filters in odd lines (with phase alternation) whereas blue components pass only alternate filters in even lines (without phase alternation). </p> |
