Abstract: A specific color detection circuit shows an RGB input pixel and an RGB color signal to be detected in a three-dimensional coordinate, calculates a first distance from an origin to a foot of a perpendicular drawn from the coordinate of the RGB input pixel to a straight line connecting the origin and the coordinate of the RGB color signal or a coordinate with the same RGB ratio as the signal and a second distance from the coordinate of the input pixel to the foot, and detects a hue of a signal of the input pixel. The circuit generates a detection region in a color-difference direction according to the first distance and the hue, calculates a third distance based on the first distance for the detection region and judges the input pixel as being in a predetermined color detection region when the third distance is longer than the second distance.

Abstract: A viewfinder control unit includes a liquid crystal viewfinder with a hood; a sensor for picking up the face of a cameraman; a pan motor for horizontally rotating the viewfinder; and a tilt motor for varying the angle the viewfinder makes with a horizontal plane to provide the cameraman with an optimum view angle. The viewfinder undergoes tracking control such that it is always trained on the face of a cameraman in response to the panning (left or right swing of a lens) and the tilting (up or down swing of the lens) of the television camera.

Abstract: An apparatus for performing a generator locking for a video signal including a first video processing circuit for processing an input video signal, an expansion module having a second video processing circuit and a delay circuit having a delay time introduced by said second video processing circuit, a synchronizing signal separating circuit for separating a synchronizing signal from an external reference signal, and a phase-lock loop circuit for generating a reference control signal for said first video processing circuit as well as a phase comparison signal. Said phase comparison signal is fed-back to the phase-lock loop circuit by means of said delay circuit. Although the expansion module is connected to the expansion slot, a phase of a finally obtained video signal is remained in a same fixed relationship as a phase relationship when a connection board is connected to the expansion slot.

Abstract: A circuit for measuring a carrier-to-noise ratio or a bit error rate of demodulated I and Q digital signals obtained by demodulating an input carrier wave which is modulated and transmitted under a carrier modulation transmission system including a discriminating circuit for producing a discrimination signal each time the demodulated digital signal comes within predetermined windows set on a signal space of the I and Q signals, a counter for counting the discrimination signals during a predetermined time interval, and a calculating circuit for calculating a carrier-to-noise ratio or bit error rate in accordance with a count value with reference to a previously stored relationship between count values and carrier-to-noise ratios or bit error rates.

Abstract: The invention relates to an apparatus for photographing and inspecting the surface of objects such as tablets. A pair of conveyor belts guided by guide rails on opposite sides of a row of suction aperture formed at even spacing in a straight line on a guide plate covering an open face of a suction box, are driven and an object seated across the pair of conveyor belts is photographed while being conveyed to thereby inspect the surface of the object. The suction apertures are formed to a size such that peripheral rims thereof are outside of the diameter of a circle having a diameter of a gap between the pair of conveyor belts on opposite sides of the suction aperture row, and the length of a portion between adjacent suction apertures is set to less than a gap between the pair of conveyor belts. Fragments of the objects being inspected are quickly sucked away from the suction apertures into the suction box, thereby preventing being caught between the conveyor belts and in the suction apertures.
