Abstract
1456671 Colour television TOKYO SHIBAURA ELECTRIC CO Ltd 29 Nov 1973 [29 Nov 1972] 55464/73 Heading H4F A colour television camera having a striped colour filter 25 including coloured strips at an oblique angle to the line scanning direction of pick-up tube 26 includes an optical filter 24 which causes image components parallel to the stripes of filter 25 to be sharply focused at tube 26 and image components parallel to the line scanning direction to be less focused at the tube 26. The filter 24 may be a lenticular lens array having the lens elements parallel to the stripes of filter 25 or a phase filter having stripes parallel to the stripes of filter 25. The filter 25 may, as shown, be used in a two-tube colour television camera and have alternate cyan and transparent stripes ; alternatively it may form part of a filter for a single-tube colour television camera. A single tube colour television camera may use two or three colour filters (Figs. 11, 13-16, not shown) at least one of which has oblique colour strips; each filter having oblique colour stripes has associated with it a phase filter with stripes parallel to the colour filter strip. The resulting colour signals are separated using comb filters, band-pass filters, demodulators and subtractors (Figs. 7, 10, not shown).
