  • Publication number: 20170039686
    Abstract: An object of the present invention is to provide an image processing device and the like that can generate a composite image in a desired focusing condition. In a smartphone 1, an edge detecting section 107 detects an edge as a feature from a plurality of input images taken with different focusing distances, and detects the intensity of the edge as a feature value. A depth estimating section 111 then estimates the depth of a target pixel, which is information representing which of the plurality of input images is in focus at the target pixel, by using the edge intensity detected by the edge detecting section 107. A depth map generating section 113 then generates a depth map based on the estimation results by the depth estimating section 111.

  • Publication number: 20160114438
    Abstract: Provided is a method for manufacturing a bearing ring member, whereby processing cost can be reduced and a high degree of freedom in design is obtained, by disposing a metal material of a raw material (13a), the metal material having excellent metal characteristics such as fatigue strength and wear resistance and excellent processing characteristics such as hardenability, in a portion that flows to a portion (raceway surface, etc.) where the characteristics of the metal material are required during use or forging of a bearing ring member. The present invention is configured from a first metal part (23) in which the raw material (13a) is formed in a cylindrical shape, and a second metal part (24) formed in a columnar shape by a metal material having more excellent metal characteristics or processing characteristics than the first metal part (23).
