Publication number: 20190208150Abstract: A pixel array in a three-dimensional image sensor includes depth pixels and an ambient light cancellation (ALC) circuit. The depth pixels operate in response to photo control signals having different phases, and generate distance information of an object based on light reflected by the object. The ALC circuit removes an ambient light component from the reflected light, and is shared by the depth pixels. Each depth pixel includes a photoelectric conversion region, a floating diffusion region, a photo gate, and a drain gate. The photoelectric conversion region collects photo charges based on the reflected light. The floating diffusion region accumulates the photo charges. The photo gate is activated in response to one of the photo control signals. The photoelectric conversion region accumulates the photo charges when the photo gate is activated, and the photo charges in the photoelectric conversion region are released when the drain gate is activated.Type: ApplicationFiled: October 26, 2018Publication date: July 4, 2019Inventors: YOUNG-GU JIN, MIN-SUN KEEL, YOUNG-CHAN KIM

Patent number: 9838573Abstract: Methods, systems, and devices for guiding a subject back within the recognizable visual range of a multimedia system are described. According to one of the described methods, when it is determined that the target has left the recognizable range of the multimedia system, sensor information is acquired from a portable electronic device (or controller) the user has been using to control the multimedia system, and the acquired sensor information is used to determine where the user is, relative to the recognizable range. In one example, the user is asked to make a gesture with the portable electronic device, and the sensor information concerning that gesture is used to determine the user's relative location. In another example, the sensor information recorded at the time the user left the recognizable range is used to determine the user's relative location.Type: GrantFiled: September 18, 2013Date of Patent: December 5, 2017Assignee: Samsung Electronics Co., LtdInventors: Jin-Wuk Choi, Dong-Wook Kwon, Jung-Seop Kim, Kyung-Il Kim, Min-Ho Kim, Gi-Sang Lee, Sang-Bo Lee, Jin-Kyung Lee, Sun-Tae Jung, Young-Gu Jin
