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： 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 digital signal processing circuit, for example, a digital signal adder circuit suitable for use in a digital color encoder for generating a digital composite color video signal from three digital primary color signals. 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.

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.

摘要： A digital color encoder for a television camera in which during digitally modulating a carrier of 3f.sub.sc (f.sub.sc is a color subcarrier frequency) with a digital color signal which is obtained by sampling input video information data at a sampling pulse rate having a frequency of 3(n/m)f.sub.sc (with m and n being relatively small integers) at N line the digital color signal is amplitude modulated by 3-phase modulation vectors each having a phase difference of 2/3.pi. from each other so as to produce a digitally modulated color signal. At N+1 line, the digital color signal is amplitude modulated by the 3-phase modulation vectors each having a phase opposite to that at the N line so as to produce an output of N+1 line which is then phase inverted to provide a digital modulated color signal. Thus, a digital color television signal with color phase having the standard television signal format is obtained.
