  • Patent number: 10241215
    Abstract: 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.

    Abstract: In general, the subject matter can be embodied in methods, systems, and program products for identifying, by a computing system and using first and second frames of a video, a transformation that indicates movement of a camera with respect to the frames. The computing system generates a modified transformation so that the transformation is less representative of recent movement. The computing system uses the transformation and the modified transformation to generate a second transformation. The computing system identifies an anticipated distortion that would be present in a stabilized version of the second frame. The computing system determines an amount by which to reduce a stabilizing effect. The computing system applies the second transformation to the second frame to stabilize the second frame, where the stabilizing effect has been reduced based on the determined amount by which to reduce the stabilizing effect.

  • Patent number: 9756249
    Abstract: Disclosed are a system and a method for determining enabling or disabling electronic image stabilization (EIS) for a video frame. An image sensor of a camera system captures a video stream that comprises a plurality of video frames. An image processor determines availability of a computational resource that may process application of EIS on each video frame. Simultaneously, the image processor receives motion data of the camera system from a gyroscope. Based on the computational resource availability, a motion frequency threshold is determined. Based on the gyroscope motion data, a motion frequency of each video frame is estimated. The estimated motion frequency is compared to the determined motion frequency threshold. If the estimated motion frequency is greater than the determined motion frequency threshold, application of EIS is disabled. If the estimated motion frequency is less than or equal to the determined motion frequency threshold, application of EIS is enabled.

  • Patent number: 9148568
    Abstract: An image-stabilization apparatus is provided that includes an image stabilizer and a status-determining processor. The image stabilizer counterbalances a camera shake in accordance with sensor signals from a shake-detecting sensor. The status-determining processor determines whether a status of the camera is in a fixed state or in a unstable state on the basis of the signals. The status determination process is carried out at the time of exposure and the characteristics of an image-stabilizing operation are altered according to the results of the status determination process.

  • Patent number: 9129400
    Abstract: A camera of a computing device can capture two or more images of a region including an object of interest, in order to allow for separation of the object from a background of the images through a process such as image subtraction. In order to compensate for rotations of the device between image captures, an element such as an electronic gyroscope can be used to monitor changes in orientation and predict an amount of shift of objects between images. The predicted shift can be used to attempt to align images captured around the time of the rotation, in order to enable subtraction or similar processes by effectively removing the shifting effect of the rotation.

  • Patent number: 9041816
    Abstract: 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).

    Abstract: 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.

  • Publication number: 20150130954
    Abstract: 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.

  • Patent number: 9019388
    Abstract: 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.
