摘要： A CCD including primary photosensitive pixels that have a narrower dynamic range and secondary photosensitive pixels that have a wider dynamic range is used to obtain first image information from the primary photosensitive pixels and second image information from the secondary photosensitive pixels at one exposure, then the first image information and the second image information are stored as two separate files having names associated with each other. A user can select through a predetermined user interface whether or not the second image information should be stored and a dynamic range for the second image information. The dynamic range information for the second image information is stored in the file of the first image information and/or the header of the file of the second image information.

摘要： An endoscope comprising: an endoscope flexible portion that includes: a low-hardness varying portion which is located in a predetermined region extending from a distal end of the flexible portion, and has hardness varying from the lowest hardness in the flexible portion to a predetermined hardness higher than the lowest hardness, the hardness being the lowest hardness at the distal end of the flexible portion, the hardness being the predetermined hardness at a proximal end of the low-hardness varying portion; a hard portion which is located in a predetermined region extending from a proximal end of the flexible portion, and has the highest hardness in the flexible portion; and an intermediate-hardness varying portion which is located between the low-hardness varying portion and the hard portion, and has hardness gradually varying in a region extending from the proximal end of the low-hardness varying portion to a distal end of the hard portion.
