摘要： A solid state television camera having a solid state image sensing device, such as CCD image sensing device and an iris for controlling the amount of light from an image irradiated on the image sensing device. The iris is controlled by the peak level of a smear signal of a horizontal scanning line during a vertical blanking interval so that the smear signal contained in a video signal from the image sensing device is reduced. Further, the iris can be controlled by the average level of the smear signal instead of the average level of the video signal of one field as the smear signal has the whole information of the image of one field, that causes the construction of detecting circuit to be very simple and the fidelity of the iris control to be high.

摘要： A portable video camera and recording apparatus is comprised of a video camera section and a recording section. The video camera section is comprised of a CCD, analogue-to-digital converters for converting signals from the CCD into digital form. The digital signals are then processed, converted into analogue form, processed in analog form, and then output as the composite video signal. A digital luminance signal and either a digital composite color signal or a plurality of digital color difference signals are received as inputs into the recording section. If the digital composite color signal is received, then the signals are time-base-compressed, converted into analogue form, the composite color signal is frequency converted and filtered and the luminance signal is frequency modulated and filtered. Next, the signals are added together and recorded onto a recording medium. If the digital color difference signals are received, the digital color difference signals are multiplexed together, converted into analogue form, frequency modulated, filtered and then recorded onto one track on the recording medium. The digital luminance signal is time-base-compressed, converted into analogue form, frequency modulated, filtered, and then recorded onto a second track on the recording medium.

摘要： An analog-signal gate circuit or sample-hold circuit is employed for processing a dot-sequential video signal derived from a solid state imaging device such as CCD imager. By changing a signal width, gain control operation is achieved, and phase shifting operation of the video signal is done by shifting an aperture center of the dot-sequential video signal. This system may be applied to a color signal conversion system wherein a dot-sequential color signal is converted directly to an NTSC color television signal. Further, white balance control for a solid state color television camera is another application of this system.

At least two input digital signals are respectively supplied to a signal delay circuit which generates the digital signal in the form of skew bits wherein the higher bit is given a larger delay. The output signals of the signal delay circuit are supplied to an adder circuit in which the small number of bits of the digital signals are added during one clock interval. And, the output signal of the adder circuit is supplied to a further delay circuit which generates a digital signal in the form of linear bits wherein any bit in originally the same clock interval is given the same delay.
