Title: Method and device for image processing
Inventor: HIRAIWA ATSUNOBU
IPC: G06T7/00
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To divide an image into plural areas adaptively to the pattern of the image by generating a segment by merging a specific area and a fine area included in a retrieval range when the absolute value of the difference between the pixel values of those areas is smaller than a threshold. SOLUTION: A CPU 3 sets the retrieval range which is larger in the number of pixels than a reference area around the reference area and specifies as a reference area a fine area included in the retrieval range. The absolute value of the difference in pixel value between the reference area and fine area is compared with the pixel threshold. The CPU 3, at the time of judging that the absolute value is smaller than the pixel threshold, judges that the reference area (segment) and the fine area have nearly the same pixel pattern and merges the reference area and fine area with each other. When the area of the segment is not smaller than a minimum area value, the generated segment is recognized as a segment constituting the image.

Abstract: PROBLEM TO BE SOLVED: To provide a fluorescent lamp in which a light flux maintaining rate can be heightened, the consumption amount of phosphor can be suppressed, and cost can be reduced by forming a protection film without using particulate metal oxide, and provide a lighting system using it. SOLUTION: In a fluorescent lamp a protection film 7 made of phosphor powder of 1.0μm or less to 0.1μm or more in an average particle diameter is formed on the inner face of a bulb 1 in which mercury and rare gas are filled, a phosphor coating 8 which converts visible light into ultraviolet radiation is formed on the protection film 7. Thereby, since the protection film 7 is made of the particulate phosphor powder of 1.0μm or less to 0.1μm or more in an average particle diameter, the reaction of the mercury and sodium can be suppressed so that the light flux maintaining rate can be heightened. In addition, since the protection film 7 is formed of the phosphor powder, the phosphor coating 8 can be thinned by that much.
