Abstract: PROBLEM TO BE SOLVED: To obtain a video image with excellent image quality by forming an auxiliary hue area at both sides of an auxiliary reference axis set in a hue area and decomposing a hue component of an input video signal into a component of a reference axis direction and an auxiliary reference axis direction with the auxiliary area of the hue inbetween and correcting each component independently. SOLUTION: An intermediate hue setting circuit 15 sets a skin color (hue F) being an intermediate color between R and Ye in advance. A hue area discrimination circuit 16 discriminates colors of input video signals R, G, B based on data from a hue area discrimination circuit 4 and the hue F from the circuit 15 and provides the output of a prescribed control signal S. Either of prescribed constants α/β, β/α calculated based on the data from the circuit 15 by a calculation circuit 17 is selected and outputted by a constant selection circuit 18. Multipliers 19, 20 multiply the constant selected by the circuit 18 with primary color and complementary color components from a calculation circuit 15 and data are selected in response to the signal S from the circuit 4 to conduct prescribed addition and subtraction.  Thus, while suppressing the effect of an optional color onto the primary color and complementary color, effective color tone is corrected.

Title: Power supply circuit
Inventor: NAGAHARA YOSHIHARU
IPC: G05F1/56
Filed: 1980-04-08
Abstract: PURPOSE:To reduce the current loss caused by the output voltage detecting circuit, by connecting the emitter of the 2nd transistor to the emitter of the 3rd transistor in which the collector is connected to the power supply, in a regulated power supply circuit. CONSTITUTION:Assuming that the 1st transistor Q1 of hEF=100 is used and an output current up to 300mA is obtained, it is required to flow the current up to 300mA to the emitter of the 2nd transistor Q2. If the 3rd transistor Q3 has hEF=300, 10muA current is sufficient for the base. Thus, the current loss at no or light load can remarkably be reduced by selecting the resistance R2 which can flow only about 10muA current at a maximum.
