Abstract: Provided are: an electrode and a method for producing the same, with which it is possible to produce a primary battery or a secondary battery having excellent characteristics such as environment resistance; and a battery provided with the electrode. This electrode is for a primary battery or a secondary battery, and comprises a current collector and an active material layer provided on the surface of the current collector. The active material layer is composed of: a plurality of active material particles; and a layered metal sulfide for filling portions between the plurality of active material particles.

Abstract: By providing different switching points between two optical systems for the case where an image capture device such as a camera is zoomed in, when the angle of view for the captured image is transitioned from wide to tele, and for the case where the camera is zoomed out, when the angle of view of the captured image is transitioned from tele to wide, the number of switching operations between the two optical systems can be reduced.

Abstract: A digital camera comprises a first image-capturing optical system having a fixed focal length lens 2 and an image sensor 12, and a second image-capturing optical system having a zoom lens 3 and an image sensor 14. The first image-capturing optical system has a first electronic zoom range, and the second image-capturing optical system has an optical zoom range between a predetermined minimum focal length and a maximum focal length. A tele end of the first electronic zoom range is set to be at a position nearer to the wide side than the maximum focal length of the second image-capturing optical system and to be a position nearer to a tele side than the minimum focal length of the second image-capturing optical system and a wide end of the first electronic zoom range is set at a position nearer to the wide side than a minimum focal length of the second image-capturing optical system, so that the first electronic zoom range and the optical zoom range partially overlap.
