ABSTRACT:
A color TV imaging apparatus has a color TV imaging device which generates a multiplex color TV video signal by means of a photoelectric transducer section equipped with a color separation stripe filter. A first bias light supply device is located in a front portion of the imaging device where the transducer section is formed, in order to apply first bias light which improves color reproducibility in dark scenes. Disposed in a rear portion of the imaging device is a second bias light supply device which applies second bias light to the transducer section which reduces afterimages. The quantity of the second bias light is predetermined to be larger than that of the first bias light.
