  • Publication number: 20150381883
    Abstract: Provided are an image processing device, an imaging device, and an image processing method which can perform focusing control using an intuitive operation. First and second images based on image signals that are output from an imaging element including first and second pixel groups on which an object image that passes through first and second regions of an imaging lens and is pupil-divided is formed are combined and displayed on a display unit having a touch panel. It is detected whether an operation of selecting the first or the second image on the display image is performed. It is detected whether a moving operation in a direction intersecting a division direction is performed. When the selection operation and the moving operation are sequentially detected, control is performed such that a focus lens is moved in an optical axis direction of the focus lens in response to the moving operation.

    Abstract: A pipe includes a cylindrical tube main body in which electric wires are arranged, and a partition wall extending from an inner wall of the tube main body and partitioning an inner space of the tube main body into a first area and a second area. The partition wall includes: a pair of end convex portions and a concave portion. The end convex portions are edge portions of the partition wall and adjacent to the inner wall of the tube main body. Each of the end convex portions curves so as to protrude in a direction from the first area toward the second area. The concave portion is between the pair of end convex portions and curves so as to be recessed in an opposite direction from the direction in which the end convex portion protrudes. The inner wall of the tube main body includes ribs protruding inward of the tube main body and extending in the axial direction of the tube main body.
