Patent number: 10917555Abstract: An imaging unit is configured with use of an imaging element including an image output pixel and a phase difference detection pixel. A control unit performs focus control based on image-plane phase difference information obtained using the phase difference detection pixel over a predetermined period, generates focus state change information indicating whether or not a change in a focus state is a monotonous change, and continues the focus control based on the image-plane phase difference information on the assumption of a large blur state in a case where the focus state change information indicates that a change in the focus state is a monotonous change. The control unit switches from the image-plane phase difference auto-focus operation to an auto-focus operation in a case where a change in the focus state is not a monotonous change. Thus, it becomes possible to perform a high-speed and high-quality auto-focus operation.Type: GrantFiled: February 7, 2018Date of Patent: February 9, 2021Assignee: SONY CORPORATIONInventors: Yuki Asukabe, Tomoyuki Minami

Patent number: 10814436Abstract: A joined body 10 is manufactured by joining a Mo- or Ti-made terminal 14 having a Ni coating, a Au coating, a Ni—Au coating (with Ni Serving as a base) to a recess 12a formed in a plate-shaped ceramic member 12 made of alumina or aluminum nitride through a joint layer 16. The joint layer 16 contains Au, Sn, Ag, Cu, and Ti and is in contact with a bottom surface of the recess 12a and with at least part of a side surface of the recess 12a (the entire side surface in this case). In the joint layer 16, its joint interface with the ceramic member 12 is Ti-rich. When the joined body 10 is cut in its thickness direction, the ratio of the total cross sectional area of pores to the cross-sectional area of the joint layer 16 (porosity) is 0.1 to 15%.Type: GrantFiled: October 24, 2016Date of Patent: October 27, 2020Assignee: NGK Insulators, Ltd.Inventors: Tomoyuki Minami, Tetsuya Kawajiri

Publication number: 20200077030Abstract: An imaging unit 31 is configured with use of an imaging element including an image output pixel and a phase difference detection pixel. A control unit 50 performs focus control based on image-plane phase difference information obtained using the phase difference detection pixel over a predetermined period, generates focus state change information indicating whether or not a change in a focus state is a monotonous change, and continues the focus control based on the image-plane phase difference information on the assumption of a large blur state in a case where the focus state change information indicates that a change in the focus state is a monotonous change. Furthermore, the control unit switches from the image-plane phase difference auto-focus operation to an auto-focus operation of, for example, a contrast method, on the assumption of a low-contrast state in a case where a change in the focus state is not a monotonous change.Type: ApplicationFiled: February 7, 2018Publication date: March 5, 2020Inventors: YUKI ASUKABE, TOMOYUKI MINAMI
