Patent number: 10951838Abstract: An information processing device that includes an exposure control unit alternately repeats a first frame and a second frame. An infrared light irradiation control unit performs irradiation of infrared light in a predetermined infrared light irradiation period which is equal to or less than an aggregate period of the first frame and the second frame. An image signal acquisition unit acquires a first image signal which is the image signal in the first frame and a second image signal which is the image signal in the second frame. An extraction unit extracts a visible light intensity per unit time and an infrared light intensity per unit time from the first image signal and the second image signal. A generation unit generates an image signal corresponding to visible light and an image signal corresponding to the infrared light.Type: GrantFiled: July 6, 2015Date of Patent: March 16, 2021Assignee: SONY SEMICONDUCTOR SOLUTIONS CORPORATIONInventor: Tamaki Eyama

Image processing apparatus, image pickup device, image pickup apparatus, and image processing method
Patent number: 10594996Abstract: An image processing apparatus includes a separation unit, a Bayer image signal supply unit, and a signal processing unit. The separation unit separates and removes, in input image signals in which pixel signals each including an invisible light component are arranged in an array different from a Bayer array, the invisible light components from the pixel signals. The Bayer image signal supply unit arranges the pixel signals from which the invisible light components have been removed in the Bayer array and supplies the pixel signals as Bayer image signals. The signal processing unit subjects the Bayer image signals to predetermined signal processing.Type: GrantFiled: July 9, 2015Date of Patent: March 17, 2020Assignee: Sony Semiconductor Solutions CorporationInventors: Yasushi Sato, Koji Kurata, Yuta Okano, Shin Yoshimura, Tamaki Eyama, Ryuhei Hata, Masatsugu Fukunaga, Masahiro Ito -

Publication number: 20170295326Abstract: An image signal corresponding to infrared light is separated from an image signal corresponding to visible light, the visible light including an infrared light signal, even when imaging is performed while performing the infrared light irradiation. An exposure control unit alternately repeats a first frame in which an exposure time is set to a predetermined first exposure time and a second frame in which the exposure time is set to a second exposure time longer than the first exposure time. An infrared light irradiation control unit performs irradiation of infrared light in a predetermined infrared light irradiation period which is equal to or less than an aggregate period of the first frame and the second frame. An image signal acquisition unit acquires a first image signal which is the image signal in the first frame and a second image signal which is the image signal in the second frame.Type: ApplicationFiled: July 6, 2015Publication date: October 12, 2017Inventor: TAMAKI EYAMA

Patent number: 9177386Abstract: There are provided an apparatus and a method for executing calculation of a global motion vector (GMV) with a high degree of reliability. Local motion vectors (LMV) corresponding to blocks and block weights as reliability indicators of the LMVs of the respective blocks are calculated, and the global motion vector (GMV) is calculated on the basis of the block weights. By calculating a degree of reliability of the local motion vector (LMV) corresponding to each block of a target block and near-field blocks adjacent to the target block and a degree of similarity between the local motion vectors (LMV) of the target block and each near-field block, the block weight is calculated through arithmetic processing to which the degree of reliability and the degree of similarity are applied. With the present configuration, it is possible to efficiently calculate the global motion vector (GMV) with a high degree of reliability.Type: GrantFiled: July 23, 2012Date of Patent: November 3, 2015Assignee: Sony CorporationInventors: Ken Tamayama, Masaki Handa, Tamaki Eyama
