Famous Patents
Felix Hoffmann, a German chemist, was searching for something to relieve his father's arthritis. In doing so, he "rediscovered" acetylsalicylic acid and in 1900, patented a stable process for developing it. Hence, we have aspirin.

| Number | Title | Issue Date |
| 8089539 | Phase adjusting device and related art thereof A characteristic detecting unit detects characteristics of a digital imaged signal at every phase shift interval set in advance. A timing adjustment unit gives a phase adjustment instruction of a pulse so as to converge to an imaging phase in the digital imaged sign... | 01/03/2012 |
| 7200279 | Method and system for image chroma suppression A method and system for image chroma suppression of an image sensor system. Chroma suppression is performed to reduce the false color phenomena. The amount of chroma suppression is performed based on the strength of spatial frequency for a current processing pixel m... | 04/03/2007 |
| 4736242 | Transitory scanning speed phase compensation using luminance edge detection In a color imaging apparatus, an optical image is focused on a photoelectrical conversion target of a color image pickup tube through a color stripe filter having a plurality of successively arranged recurrent groups of different color stripes and convert... | 04/05/1988 |
| 4480266 | Method and apparatus for preventing generation of false color signals in color television cameras In a color television camera of the type in which the red and blue color component signals modulated spatially by color filters and generated from a pick up tube are demodulated by the technique of phase separation through the utilization of correlation i... | 10/30/1984 |
| 4157566 | Single tube color television camera with color correction The present invention is a color television camera employing a single pick-up tube and producing color component signals utilizing a difference of phase relationships of the modulated color signals, at least one of which changes in successive horizontal s... | 06/05/1979 |
| 4085418 | Color image pick-up system using strip filter A color filter strip arrangement for a color television camera tube which produces luminance and chrominance signals, and in which the chrominance signals are separated from each other by phase division. A biasing light source is provided for illuminating... | 04/18/1978 |
| 4004292 | System for producing chroma signals Disclosed is a method and system for obtaining electronic chroma signals with a single scanning-type image device by optically producing a color multiplexed light signal using an arrangement of dichroic filter stripes. In the particular embodiment describ... | 01/18/1977 |
| 3935588 | Color image pick-up system using strip filter A color filter strip arrangement for a color television camera tube which produces luminance and chrominance signals, and in which the chrominance signals are separeted from each other by phase division. A biasing light source is provided for illuminating... | 01/27/1976 |
