Color TV camera with circuit for adjusting the white balance of red, green, and blue signals generated from a narrow-band luminance signal and line-sequential color-difference signals

Claim 1

A solid-state color television camera having a solid-state image sensing device with a color filter from which a luminance signal component and line-sequential color-difference signal components are generated, comprising: a signal converting means supplied with said line-sequential color-difference signal components for converting the same into first and second simultaneous color-difference signals; a signal separating means supplied with said first and second simultaneous color-difference signals and at least a first portion of said luminance signal component for generating first, second and third primary color signals; a level control means for controlling the levels of at least two of said primary color signals to achieve a white balance control; a matrix means supplied with the level-controlled primary color signals from said level control means and any of said primary color signals whose levels are not controlled by said level control means for generating at least first and second color-difference signals; and an encoding means supplied with the first and second color-difference signals from said matrix means and at least a second portion of said luminance signal component for generating a composite color video signal.
