摘要:
A television camera equipped with an active filter section capable of producing dynamic special effects in the picture. The filter section of the camera includes an electro-optic light control device which is arranged in the optical path of the imaging optical section of the television camera such that its light transmittance for the incident light to the image screen of the camera is varied in response to the application of an electric signal, and the variable transmittance area is divided into a plurality of sections adapted to be controlled and drived selectively. Also, the camera includes a drive unit for selectively controlling and driving the sections of the electro-optic light control device so as to vary with time the spread of the area of the sections having the transmittance varied in response to the application of the electric signal.
