Patent number: 10241215Abstract: A calibration scheme measures roll, pitch, and yaw and other speeds and accelerations during a series of vehicle maneuvers. Based on the measurements, the calibration scheme calculates inertial sensor misalignments. The calibration scheme also calculates offsets of the inertial sensors and GPS antennas from a vehicle control point. The calibration scheme can also estimate other calibration parameters, such as minimum vehicle radii and nearest orthogonal orientation. Automated sensor calibration reduces the amount of operator input used when calibrating sensor parameters. Automatic sensor calibration also allows the operator to install an electronic control unit (ECU) in any convenient orientation (roll, pitch and yaw), removing the need for the ECU to be installed in a restrictive orthogonal configuration. The calibration scheme may remove dependencies on a heading filter and steering interfaces by calculating sensor parameters based on raw sensor measurements taken during the vehicle maneuvers.Type: GrantFiled: November 14, 2016Date of Patent: March 26, 2019Assignee: AGJUNCTION LLCInventors: Eran D.

Patent number: 9041816Abstract: The purpose of the present invention is to provide an optical unit with a shake correction function such that even when a photo reflector is provided by using a gap between a side surface of a movable body and a side surface of a fixed body, an appropriate relationship between an output from the photo reflector and the rock angle of the movable body can be obtained. In an optical unit (100) with a shake correction function, a movable body (3) is rocked about a rock fulcrum (180) by a driving mechanism (500) for shake correction, and thereby shaking is corrected. At that point, the movement of the movable body (3) is monitored by providing a first photo reflector (580a) and a second photo reflector (580b) on side surfaces of a fixed body (200).Type: GrantFiled: March 29, 2012Date of Patent: May 26, 2015Assignee: NIDEC SANKYO CORPORATIONInventor: Yuichi Takei

Publication number: 20150138382Abstract: Various embodiments provide methods, apparatus, and electronic devices for image capturing. An exemplary image capturing method can include first acquiring image information via a camera contained in an electronic device and then detecting whether a shake amplitude of the electronic device is within a pre-set range. When the shake amplitude of the electronic device is detected within the pre-set range, the image information acquired by the camera can be captured. An exemplary image capturing apparatus can include an acquisition module for acquiring image information; a first detection module for detecting whether a shake amplitude of an electronic device is within a pre-set range; and a capturing module for capturing the image information, when the first detection module detects that the shake amplitude of the electronic device is within the pre-set range.Type: ApplicationFiled: January 15, 2015Publication date: May 21, 2015Inventors: BIN XIAO, HAILONG LIU, WEN ZHA

Publication number: 20150130954Abstract: Embodiments of the invention provide an image correcting apparatus for an imaging device including a camera module having a first motion sensor. The image correct apparatus includes a second motion sensor sensing a movement, and a controller determining whether the movement gets out of an operation range of the first motion sensor, and correcting an image obtained from the camera module based on movement data sensed by the second motion sensor, when the movement gets out of the operation range of the first motion sensor. Generation of blur in an image when a displacement of handshaking is at an angle equal to or greater than a correction angle of an optical image stabilizer (OIS) module is prevented, and thus, a clear image is obtained.Type: ApplicationFiled: April 30, 2014Publication date: May 14, 2015Applicant: SAMSUNG ELECTRO-MECHANICS CO., LTD.Inventors: Hae Seung HYUN, Hee Bum LEE

Patent number: 9019388Abstract: The present invention prevents unnecessary imaging operations when imaging is not required to be performed. In the present invention, a display panel includes a touch panel provided on the top surface thereof. An image sensor of an imaging section captures an image. A gyro sensor detects the movement of an imaging device. When the movement of the imaging device is detected by the gyro sensor, a control section prohibits an imaging operation by the imaging section in response to a touch operation performed on the touch panel. Conversely, when the movement of the imaging device is not detected by the gyro sensor, the control section performs an imaging operation by the imaging section in response to a touch operation on the touch panel.Type: GrantFiled: September 14, 2012Date of Patent: April 28, 2015Assignee: Casio Computer Co., Ltd.Inventor: Kenji Yoshizawa
