Title: Gradation correction device
Inventor: NAKAHIGASHI HIDETO
IPC: H04N9/64
Filed: 1994-04-28
Abstract: PURPOSE:To obtain the gradation correction device in which an arithmetic rate of correction processing is decreased even to a luminance signal with a high gradation bit and gradation correction processing is applied to each gradation of an input luminance signal in the unit of picture elements while reducing the processing quantity simultaneously. CONSTITUTION:A histogram arithmetic circuit 103 extracts a characteristic of luminance distribution and the obtained correction data are stored in a lookup table 110 and selectors 114,115 and an adder 116 are used to apply interpolation processing to the correction data by using a low-order bit reduced at the extraction of the characteristic of the luminance distribution as a control signal. Thus, the gradation correction for gradation correction processing in the unit of picture elements is realized with respect to each gradation of an input luminance signal without roughing gradation bits of the correction signal with respect to the input luminance signal in the calculation of the gradation correction.

Title: Burnout circuit of four-wire measured resistor
Inventor: CHIBA HIROMI
IPC: G08C25/00
Filed: 1979-07-20
Abstract: PURPOSE: To operate a control system to the safety side, by constituting the circuit so that the output may be always set to burnout and upscale when various abnormal states dependent upon disconnection of a measured resistance are generated.  
     CONSTITUTION: When the first current supplying lead wire A1 of thermometric resistor 1 is disconnected, values of positive phase input impedance Z1 of differential amplifier 3, resistance R5 and resistance R6 are very large in comparison with respective related resistance values, and therefore, constant current (i) from constant current source 2 flows through D1→R3→Rt→Rb, and Zener diode ZD is cut off. Therefore, voltage e 1  at the positive phase input terminal of differential amplifier 3 is shown by expression I. Voltage Rb.i generated across bias resistance Rb is shown by expression II. These relations are substituted into expression III under conditions of burnout and upscale to obtain expression IV. Consequently, the output can be set to burnout and upscale by selecting the value of resistance R3 larger than the value of measuring input span resistance ΔRts, so that the control system can be operated to the safety side.
