Title: Picture processor
Inventor: MATSUNAWA MASAHIKO
IPC: H04N1/48
Filed: 1988-01-28
Abstract: PURPOSE:To attain object picture processing without deteriorating picture quality by applying magnification/reduction processing being conversion processing of picture element density after color separation and before mutli-value processing. CONSTITUTION:Digital, picture signals VR, VC subject to shading correction are applied to a color discrimination circuit 35 to discriminate into plural chrominance signals. Then the result is fed to a color ghost correction means 300 of the next stage, where color ghost in the main scanning direction (horizontal scanning direction) and in the subscanning direction (drum rotating direction) is corrected. Then the signal passes through a magnification reduction circuit 1, where magnification/reduction processing is applied as required. The picture data after magnification is subject to next resolution correction (MTF correction). Thus, the picture processing attended with picture quality deterioration such as rugged slant lines is hot applied at magnification of picture.

When the load on the hydrogen consuming side decreases here, the measured pressure value of a pressure controller C5 detected with a pressure detector P4 rises and exceeds a set value, thus opening a control valve V6. An arithmetic device 5 in this state receives the outputs from the detector P4 and a flow rate detector F4 and applies the fresh set value MV' obtd. by subtracting a specified value alpha from the set signal MV to an operator M in the stage when conditions are satisfied, thereby closing a control valve V4 and decreasing the gaseous pressure in the inlet of the furnace 3. A timer built in the device 5 is then started and when the system stabilizes, the detectors P4, F4 are checked and this operation is repeated. Thus, the flow rate of the raw materials according to the decrease in the load is controlled.

Abstract: PROBLEM TO BE SOLVED: To reduce irregular tone at the time of muting by making a differential amplifier operate by a starting means and making the level variation of a control signal added to a level-adjusting circuit gentle, through the use of the voltage current converting characteristic of the differential amplifier. SOLUTION: When muting from a maximum volume state or rapid lowering a volume is done, the output terminal 7 of a D/A converter 3 tries to immediately lower from a maximum value, but the value is lowered gradually due to the presence of a resistor 8.

As soon as the switch 21 is closed, a subtle current flows through the collector of a transistor 19, and most of the current of the current value of an operation current source 20 flows to the collector of a first transistor. The base voltage of the first transistor 17 drops. When the collector current of the second transistor 19 is increased according to the portion, the base voltage of the first transistor 17 drops again to constitute a positive feedback loop, and the amplifier 16 executes inversion operation.
