Publication number: 20110007361Abstract: An image processing device includes a multiplier 1 for multiplying a pixel signal P(x) by a weighting factor ?0 (0??0?1), a delay element 2 for delaying the pixel signal P(x) which has not been multiplied yet by the weighting factor ?0 by the multiplier 1 by one pixel, and a multiplier 3 for multiplying the pixel signal P(x?1) delayed by the delay element 2 by a weighting factor ?1 (0??1?1), the total sum of the weighting factors ?0 and ?1 being larger than 1 and smaller than an upper limit ?max. An adder 4 adds the multiplication result ?0·P(x) of the multiplier 1 and the multiplication result ?1·P(x?1) of the multiplier 3, and a limiter 5 limits the addition result P?(x) of the adder 4 in such a way that P?(x) falls within a maximum density value Pmax.Type: ApplicationFiled: November 16, 2006Publication date: January 13, 2011Inventors: Toshiyuki Takahashi, Atsushi Hori, Yuka Fujita, Koichi Hiramatsu, Takeo Kawaura

Patent number: 6770517Abstract: In a silicon layer formed on an insulator layer, a lattice defect region is formed to be adjacent to a channel region and source/drain regions, and the lower part of the channel region functions as a high-concentration channel region. The holes of hole-electron pairs generated in the channel region are eliminated by recombination in the lattice defect region, thereby suppressing the bipolar operation resulting from the accumulation of holes and increasing the source/drain breakdown voltage. The threshold value of a parasitic transistor is increased by the high-concentration channel region so as to reduce the leakage current in the OFF state. Alternatively, the holes may be moved to the source region to disappear therein by providing, instead of the lattice defect region, a high-concentration diffusion layer constituting and operating as a pn diode between the channel and source regions.Type: GrantFiled: December 28, 2001Date of Patent: August 3, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroaki Nakaoka, Hiromasa Fujimoto, Atsushi Hori, Takashi Uehara, Takehiro Hirai
