Publication number: 20230341556Abstract: The present technology relates to a distance measurement sensor, a signal processing method, and a distance measurement module that enables detecting that an object to be measured is a transparent object such as glass. The distance measurement sensor includes a signal processing unit that calculates a distance to an object and a degree of confidence from a signal obtained by a light receiving unit that receives reflected light returned by reflection, by the object, of irradiation light emitted from a predetermined light emitting source, and outputs a determination flag determining whether or not the object that is an object to be measured is a transparent object. The present technology can be applied to, for example, a distance measurement module that measures a distance to a subject, and the like.Type: ApplicationFiled: September 16, 2020Publication date: October 26, 2023Inventors: TOMOICHI FUJISAWA, YASUHIRO OKAMOTO, KAZUKI OHASHI, MASAKAZU KATO, DAISUKE FUKAGAWA

Patent number: 8582029Abstract: A picture signal processing unit having a first and a second double rate conversion section, a storage section, and a quadruple rate conversion section is provided. The first double rate conversion section inserts a first interpolation frame between a couple of successive original frames to output the original frames and the first interpolation frames. The second double rate conversion section generates a second and a third interpolation frames and allocates the second and the third interpolation frames between the couple of successive original frames to output the second and the third interpolation frames. The storage section stores the original frame and the first to the third interpolation frames. The quadruple rate conversion section sequentially reads out the original frame and the first to the third interpolation frames from the storage section in a quadruple rate to output the original frame and the first to the third interpolation frames.Type: GrantFiled: August 19, 2009Date of Patent: November 12, 2013Assignee: Sony CorporationInventors: Shinichiro Miyazaki, Tomoichi Fujisawa
