Patent number: 10101874Abstract: A method for controlling a user interface of an apparatus to enable intuitive manipulation for an object included in an image is provided. An object with deeper depth in a rear image of the apparatus may become selectable when the user holds a user input means close to the apparatus, while an object with shallower depth in the rear image may become selectable when the user draws the user input means away from the apparatus, thereby allowing the user to intuitively select an object in the rear image.Type: GrantFiled: September 30, 2013Date of Patent: October 16, 2018Assignee: Samsung Electronics Co., LtdInventors: Dong-Wook Kwon, Min-Ho Kim, Kyung-Il Kim, Gi-Sang Lee, Sang-Bo Lee, Jin-Kyung Lee, Young-Gu Jin, Jin-Wuk Choi

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

Patent number: 9829983Abstract: A mobile system may comprise a three-dimensional (3D) image sensor on a first surface of the mobile system configured to perform a first sensing to detect proximity of a subject and a second sensing to recognize a gesture of the subject by acquiring distance information for the subject; and/or a display device on the first surface of the mobile system to display results of the first sensing and the second sensing. A mobile system may comprise a light source unit; a plurality of depth pixels; and/or a plurality of color pixels. The light source unit, the plurality of depth pixels, or the plurality of color pixels may be activated based on an operation mode of the mobile system.Type: GrantFiled: October 23, 2013Date of Patent: November 28, 2017Assignee: Samsung Electronic Co., Ltd.Inventors: Yoon-Dong Park, Won-Joo Kim, Young-Gu Jin, Dong-Wook Kwon, Kyung-Il Kim, Min-Ho Kim, Gi-Sang Lee, Sang-Bo Lee, Jin-Kyung Lee, Jin-Wuk Choi

Patent number: 9773164Abstract: An apparatus and a method for recognizing a human body in a hybrid manner are provided. The method includes calculating body information used for recognizing a human body from an input image, detecting a region of the human body in a learning-based human body recognition manner by using the calculated body information, and tracing a movement of the detected region of the human body in a modeling-based human body recognition manner. Thereby, it is possible to quickly perform more accurate and precise recognition of the human body.Type: GrantFiled: May 20, 2014Date of Patent: September 26, 2017Assignee: Samsung Electronics Co., LtdInventors: Jin-Wuk Choi, Ho-Yub Jung, Jung-Seop Kim, Nam-Su Ha, Dong-Wook Kwon, Kyung-Il Kim, Min-Ho Kim, Gi-Sang Lee, Sang-Bo Lee, Jin-Kyung Lee, Young-Gu Jin

Patent number: 9594945Abstract: A method and an apparatus for controlling a display in order to secure an appropriate viewing distance between a digital device and a user who is viewing the digital device is provided. Accordingly, the method determines whether an object exists within a hazardous viewing distance using a 3D camera function provided in the digital device. If it is determined that an object exists within the hazardous viewing distance, the digital device detects a face or eyes from 2D images photographed by the camera. Next, the direction of the face is determined on the basis of the detected results, and it is determined whether a user is viewing a display screen of the digital device based on the determination.
