Abstract: A solid state imaging device comprises a color filter, a pixel, and first and a second output lines. The color filter has color filter components of a first and second color. Each pixel is covered by the color filter component and has a photoelectric conversion element. The photoelectric conversion element generates color pixel signals according to amount of light received by the photoelectric conversion element. A first pixel is covered by the first color filter component. A first color pixel signal is generated by the first pixel. The first output line outputs only the first color pixel signal. A second pixel is covered by the second filter component. A second color pixel signal is generated by the second pixel. The second output line outputs only the second color pixel signal. The first and second pixels are arranged in two dimensions.

Abstract: An endoscopic tissue collecting instrument includes an outer sheath that has an annular blade portion formed on the outer periphery of its distal end and which has a tissue retaining recess formed in the lateral side of an area close to the blade portion, and an inner needle that is fitted into the outer sheath to be capable of moving back and forth along the longitudinal axis and which has formed at the distal end a cutting blade for cutting off the tissue entering the tissue retaining recess and a needle tip pointed forward. The inner needle can be manipulated by the operator to move back and forth between two positions, one being where its distal end is drawn into the outer sheath such that it does not close the tissue retaining recess and the other being where it protrudes from the distal end of the outer sheath.
