  • Digital video signal processing device and TV camera device arranged to use it
    Patent number: 5512946
    Abstract: A digital video signal processing device for clipping a digital video signal to keep the signal at a predetermined level, includes an interpolation data signal generating unit for predicting video signal levels between adjacent sampling points for generating an interpolation data signal, clipping units for clipping the sampled video signal and the interpolation data signal at their levels, and a synthesizing unit for performing a predictive coding operation with respect to at least any one of the clipped video signal and the interpolation data signal and synthesizing these signals with each other.

  • Residential facility control system
    Patent number: 5446453
    Abstract: A residential facility control system transmits data as a radio signal between host and subsidiary apparatus. Transmitting and receiving devices of the host and subsidiary apparatus are reduced in power consumption. A transmitting circuit of the transmitting device of the transmitting and receiving apparatus is supplied with power from a transmitting circuit power source control in synchronization with a first timing signal from a first timer for a period of time which is necessary for transmission. A receiving circuit of the receiving device of the transmitting and receiving device is supplied with power from a receiving circuit power source control for a shorter period of time in synchronization with a second timing signal from a second timer which is synchronized with the first timing signal.

  • Automatic iris adjustment system
    Patent number: 4638366
    Abstract: An automatic iris adjustment system comprises a camera lens including an iris driving means for controlling the iris value; an image pickup element for converting the amount of light incident to the camera lens into an electrical signal; means for comparing the iris adjustment signal voltage V.sub.I from the image pickup element with the reference voltage V.sub.O to evaluate an error voltage V.sub.E (i.e., V.sub.E =V.sub.I -V.sub.O); means for calculating a varying component .DELTA.IRIS of iris control value as a predetermined function of the error voltage V.sub.E ; means for calculating an iris control value IRIS.sub.n basing on the calculated varying component .DELTA.IRIS of iris control value; and means for controlling the iris driving means in response to the calculated iris control value IRIS.sub.n.
