-18- ABSTRACT A color TV imaging apparatus comprises a TV imaging device for generating a composite color TV video signal by use of a color separation stripe filter, at least two demodulators for individually producing color signal components by demodulating carrier signals which are contained in an output signal of the imaging device and processed into carriers, and a bias light supply device for applying bias light to a photoelectric transducer section of the imaging device through the filter. At least one of the quantity and color temperature of the bias light is set such that the carrier color signals to be demodulated by the demodulators become greater than the peak-to-peak value of noise contained in the signal. The quantity of bias light is adjusted by controlling bias light sources of the bias light supply device, while a color temperature of bias light is selected by means of color temperature conversion filters positioned in light outlet portions of a flat light conducting element which is included in the bias light supply device.
