  • Electronic device including a housing and a camera that is activated based on a posture and a grabbing form
    Patent number: 9594292
    Abstract: An electronic device includes a camera; an acceleration sensor that detects an acceleration applied to a housing; a posture determining unit that determines a posture of the housing based on a value detected by the acceleration sensor; and an activation control unit that activates the camera when the posture determining unit determines that the posture of the housing becomes an upright posture.

  • ELECTRONIC APPARATUS AND PROGRAM
    Publication number: 20150260750
    Abstract: An electronic apparatus includes: a sensor unit configured to detect displacement information of a body including at least acceleration data; a still determination unit configured to determine whether or not the body is in a still state based on a change in a standard deviation with respect to the displacement information for a predetermined number of detections detected by the sensor unit; a gravity calculation unit configured to determine a start of a motion of the body based on a determination result determined by the still determination unit and calculate a gravity component based on first acceleration data that is acceleration data in the start of the motion of acceleration data detected by the sensor unit; a correction unit configured to correct second acceleration data that is acceleration data detected by the sensor unit while the body is moving, based on the gravity component calculated by the gravity calculation unit; and a motion determination unit configured to determine the motion based on the se
