Patent number: 6748049Abstract: X-ray camera of the present invention comprises an X-ray irradiation unit, an X-ray image sensor, a controller having a correction factor setting unit, a correction factor storage unit and a correctional operation unit, and a display unit. The X-ray image sensor in the above configuration comprises a sensor such as CCD, TFT, and the like having a scintillator on a surface thereof, and a substrate having the sensor mounted thereon. The correction factor setting unit obtains a value La/Ln by dividing a predetermined brightness reference value La set beforehand by a brightness value Ln of an arbitrary pixel “n”, and sets the obtained value as a correction factor for each pixel. The correction factor storage unit stores the correction factor set by the correction factor setting unit. The correctional operation unit obtains the correction factor from the correction factor storage unit, and performs a corrective operation.Type: GrantFiled: January 22, 2001Date of Patent: June 8, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Toshiyoshi Yamamoto, Takuo Shimada, Atsushi Sakata, Kazuya Kondo, Yoshihiro Ino

Patent number: 6559575Abstract: A cathode ray tube and a color selecting member, which can be manufactured without defects by using an existing projection aligner of a simple structure and can always produce a picture of high quality, in which phosphor layer has a pattern in stripes in the lateral direction of a screen, or in the horizontal direction and a color selecting member has slits elongated in the longitudinal direction of the screen, or in the horizontal scan line direction. Even in case of the thermal expansion of the color selecting member or a considerable longitudinal deviation between the exposure position at the time of manufacture and the position where an electron beam strikes in actual use, an electron beam can freely pass through the slits. Therefore, the accuracy of irradiation of the phosphor layer with the electron beam is not adversely influenced.Type: GrantFiled: May 10, 2000Date of Patent: May 6, 2003Assignee: Sony CorporationInventors: Atsushi Sakata, Katsutoshi Ohno, Shoichi Muraguchi, Masamichi Okada, Takahiro Inoue
