Abstract

A solid state color television camera having a color filter consisting of first and second color filter elements through which red and green primary color lights pass and a third color filter element through which a blue color light and the red color light pass and a solid state image sensing device, in which from the solid state image sensing device there are obtained a red primary color signal in response to a red primary color information passed through the first filter element, a green primary color signal in response to a green primary color information passed through the second filter element, a composite color (magenta) signal in response to a color information passed through the third filter element, a luminance signal is provided from the red and green primary color signals and the composite color signal, a blue primary color signal is provided by calculating the composite color signal and the red primary color signal, and a carrier color signal is provided from the red, green and blue primary color signals.

Dependent claims

A solid state television camera having a solid state image sensing device including a plurality of individual light sensing units arranged in both horizontal and vertical rows comprising:

(a) a plurality of color filter elements with different transmissibilities faced with said individual light sensing units including first and second color filter elements for transmitting first and second primary color signals and third color filter elements for transmitting both of a third and said first primary color signals as a composite color signal;
(b) a switching circuit for converting line sequential signals produced from each of said light sensing units into a simultaneous color signal;
(c) an adder for adding said first and second primary color components and said composite color signal produced from each of said light sensing units faced with said first, second and third color filter elements individually by which a luminance signal is composed;
(d) a mixer for mixing said composite color signal and said first primary color signal from which said third primary color signal is produced;
and
(e) a color encoder for encoding said first, second and third primary color signal components from which a composite color television signal is produced.
