Abstract: PURPOSE:To obtain an outline emphasizing circuit of a video signal composed of an easy logical circuit by providing a shift register which inputs a digital video signal, an adder and a multiplier which multiplies the scale factor to the intermediate part memory cell and a substracter. CONSTITUTION:A digital video input signal (a) and an output signal (b) of a shift register 11 outputted by the time delay of 2t later than this are added by an adder 12. When the peak value of a digital video input signal (a) is (h), an output signal (c) of the adder 12 goes to be a projection shape waveform, and the peak value goes to be two stages of 2 h and (h). A multiplier 13 multiplies the necessary scale factor, the peak value of the output signal (e) is (g), and then, the waveform is later for the time (t) only than the digital video input signal (a). A substracter 14 substracts the output signal (c) of the adder 12 from an output signal (e) of the multiplier 13, the waveform of the output signal (f) is a symmetrical trapezoidal wave, has a recessed part of the depth (h) at both edges of the trapezoid, the rise emphasized by peak values g-h can be formed at this, moreover, the protruded part of height (h) is formed at the trapezoidal edge part for the peak value of the trapezoidal central part, and the outline part is emphasized.

Abstract: PURPOSE:To prevent variance due to measuring error and integration effect by sampling a noise level and a video signal at plural number of times and using noise data and video image data with high data measuring accuracy to calculate a noise equivalent temperature difference and a minimum searchable temperature difference. CONSTITUTION:A sample-and-hold circuit 7 samples a noise E outputted sequentially from an infrared-ray video image device 2 and a video signal F superimposed with the noise and outputs the result to an A/D converter 8. The converter 8 converts the noise E and the signal F into a digital signal and outputs the signal to a storage section 9. The storage section 9 outputs sequentially the noise data and video image data to a computer 5 sequentially. The computer 5 processes statistically plural noise data and video data, selects the noise data and video image data with high data reliability and uses the selected data to calculate the noise equivalent temperature difference and a minimum searchable temperature difference.

Abstract: PURPOSE:To attain the automatic frequency control with high accuracy and speed, by integrating an input signal level for output every time when a sampling pulse is applied in a circuit automatically tracking the frequency of a voltage controlled oscillator. CONSTITUTION:Two sampling hold circuits H1, H2 are connected in feedback connection with each other, and an astatic control is performed by integrating the sampling output of the input signal level, every time when sampling pulses (smp)1, (smp)2 are applied to the circuits H1, H2. The static control is performed when the circuit H1 is in sampling state. The voltage controlled oscillator is controlled with an output signal of the circuit H1, allowing the oscillation output to follow the transmission wave with good accuracy in high speed automatically.

Abstract: PURPOSE:To attain high resolution processing for a A/D converter, and to attain miniaturization and low power consumption by applying A/D conversion to an input signal with a low resolution A/D converter, dividing the signal into a small range as an offset voltage, applying A/D conversion to a difference resulting from subtracting the offset voltage from the input signal with an accurate A/D converter and synthesizing them after A/D conversion. CONSTITUTION:All levels of an input signal IN are divided into a small ranges of 2 =2 =8 and rough A/D conversion is applied to the signal depending on its level by a low resolution A/D converter 22 and the result is outputted to a window selector 23. The selector 23 divides output data into small ranges (R0-R7), which are converted into an analog signal by a D/A converter 24. The analog signal is used for offset voltages (0V, Vc1-Vc7) and a difference DELTAA between an output Vi of a sample-and-hold circuit 27 sampling and holding the input signal IN and each of the analog offset voltages is obtained by a subtractor 25 and an accurate A/D converter 21 is used to apply A/D conversion to the difference. Its output data DELTAD are added to a range designation signal from the selector 23 at a data synthesizer 26 to obtain a digital output signal OUT. Thus, the A/D converter with high resolution is obtained.

CONSTITUTION:A robot 5 comprising a hand 1; an arm 2; a drive part 3; and a various sensors 4 consisting of a television camera, a limit sensor, and a temperature sensor is controlled by a remote operation control part 7 through a control part 6. The mechanical state change of the robot 5 is detected by means of a limit sensor. When a detected state is a risky state, direct risk avoidance control of the drive part 3 is performed by a first control mechanism. When it is decided by the control part 6 based on information from the television camera that a risky state is produced, the drive part 3 is controlled by a second control mechanism. When it is decided by the remote operation control part 7 from information from various sensors 4 that a risky state is produced, a command is outputted to the control part 6 from a third control mechanism to perform control.

Abstract: PURPOSE:To perform driving control of the lens system and to smoothly perform the operation at the time of driving by judging the focusing by a picture signal by the use of an electronic circuit regarding the automatic focus adjustment system in the infrared ray camera. CONSTITUTION:The high-pass component of an electric signal from an infrared ray detection section 2 is extracted by an filter 3 for extracting the space frequency component for a infrared ray camera section obtaining the two-dimensional infrared ray picture signal by the scanning in the vertical direction of the infrared ray detection element of the infrared ray detection section 2 placed on an image forming surface of a lens system 1, and by the deflection and scanning in the orthogonal direction to the scanning of the lens system 1. An arithmetic section 4 detects the increasing state of the high frequency component and generates a signal showing the focusing state. A lens system movement mechanism 5 moves the lens system 1 according to the output of the arithmetic section 4. The control is performed constantly so that the infrared ray image of the infrared ray detection section 2 is focused. Further, the speed control, stop control, and prediction control is performed at the time of moving the lens system 1 and the operation is made smooth.
