  • Patent number: 8097048
    Abstract: Disclosed is a PPS member having an excellent fastness to lights such as ultraviolet light, and of which color does not change even when the member is used outdoors, while retaining the characteristics of PPS. The polyphenylene sulfide member according to the present invention is characterized by having a light-fastness rating of Class 1 or higher, against light from an ultraviolet carbon arc lamp, which rating is measured in accordance with JIS L-0842.

  • Publication number: 20090244321
    Abstract: In a case of using a CCD or analog circuit of a poor quality where an error in hue or the like causes a problem, such an error in hue or the like may not be dealt with. In correcting pixel output values of a CCD, there are prepared beforehand a plurality of correction approximate straight-line group information or a set of correction approximate straight-line group information and a plurality of error correction approximate straight-line group information, and the most suitable one of them is dynamically selected. Alternatively, the gain is dynamically decided by use of a ratio-based correction from a plurality of candidate correction approximate straight-line group information (error correction approximate straight-line group information). Additionally, the ratio of color components (carrier components) is used to select the correction approximate straight-line group information (error correction approximate straight-line group information) and to decide the ratio of the correction.
