Title: Color image pickup device
Inventor: MACHIJIMA EIJI
IPC: H04N9/07
Filed: 1993-07-27
Abstract: PURPOSE:To improve the deterioration of color reproducibility even when the dispersion of a color filter is generated by providing a means which eliminates a negative component in at least a red or blue chrominance signal system between a primary color separation means and a color difference matrix circuit. CONSTITUTION:Slicing circuits 32R, 32B which eliminate the negative component are inserted to a red chrominance signal R system and a blue chrominance signal B system between a white balance circuit 15 and a gamma(gamma) correction circuit 17a. respectively by using an additive complementary color coding CCD image pickup element 1. The negative components of a red chrominance signal R and a blue chrominance signal B obtained at the output side of the white balance circuit 15 after separating the primary colors of the red, green, and blue chrominance signals R, G, and B are eliminated by the slicing circuits 32R, 32B. Consequently, it is possible to prevent the degree of saturation of cyan Cy from being increased compared with another color, and also, the degree of saturation of colors other than yellow Ye from being decreased, which improves the deterioration of color reproducibility.

Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To realize effective brake control on an inclined road or the like by making it capable of the same braking distance if it is a treadling method of the same brake pedal, in case of braking on a sloping road or the like.

Filed: 1982-10-27
Abstract: PURPOSE:To enable to effectively protect a motor against an overspeed even in a device which has no speed feedback loop by detecting directly the presence or absence of the abnormal increase in the frequency. CONSTITUTION:A signal S1 is applied to a monostable multivibrator 1, which, in turn, outputs a pulse signal S2 having the prescribed period width.
