Title: Color signal amplifier
Inventor: MAEDA TETSUHIRO
IPC: H04N9/31
Filed: 1990-11-20
Abstract: PURPOSE:To control a color signal level in response to an APL even in a multi- vision device by providing a color signal amplifier whose gain is controlled with an output resulting from adding an output of a detection circuit to a control voltage when the output of the detection circuit is larger than the control voltage to the amplifier circuit. CONSTITUTION:When an APL detection voltage is higher than a control voltage, a comparison output goes to H, a gate circuit 9 is opened and an APL detection voltage passes. Then a voltage resulting from superimposing an APL detection voltage onto the control voltage is outputted from an adder circuit 10. That is, when the APL is low, the output of an adder circuit is constant and a color signal output level is constant, and when the APL is higher and the APL detection voltage is higher than the control voltage, the output of the adder circuit 10 is increased proportional to the APL, then the color signal output level is increased. Thus, even in the multi-vision device, the color signal level is controlled in interlocking with the APL and a picture with excellent balance between the luminance and chrominance is obtained.

IPC: H04L1/00
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To provide the parity arithmetic circuit that designates a normal parity arithmetic range in a 1st parity arithmetic operation after recovered from out of synchronism in a synchronization transmission system.

Filed: 1990-11-24
Abstract: PURPOSE:To improve image quality as a whole by subjecting a region where the inclination of a density conversion curve is large to selective smoothing space filtering processing. CONSTITUTION:The coordinate system corresponding the density value (density value of an original image) on an input side and the density value (density value after density conversion) on an output side is displayed on a color display 7.

Only the density-converted density data belonging to the density region where the absolute value of the differentiation coefft. of the density conversion curve attains a predetermined value or above is subjected to the smoothing space filtering processing. The tone jump and the generation of false contours in the region are suppressed in this way and there is no blur of the images by the smoothing processing in other regions. The image quality is thus improved as a whole.
