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.

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.

摘要： A solidstate digital television camera which has a solid state image sensing device, an A-D converter for converting the output of the image sensing device to a digital color signal, a filter for providing a predetermined filter characteristic to the digital color signal, and a digital color modulator for modulating the output of the above filter to produce a digital modulated signal.In the digital television camera, the processing rate between the solid state image sensing device and the filter is selected to have a sampling rate equal to that of the solid state image sensing device, or (n/m)pF.sub.sc where f.sub.sc is a color subcarrier frequency, p is 3 or 4, and m and n are relatively small integers. The processing rate for the remaining elements is selected to be pf.sub.sc. In addition, a D-D converter for converting the processing rate from (n/m)pF.sub.sc to pf.sub.sc is provided between the filter and the digital modulator. Thus, the digital television camera can be operated at a relatively slow sampling drive rate and can be constructed from integrated circuits.
