Camera with acceleration sensor
InactiveUS20060204232A1Reduce movement-induced image blurringAdjusts exposure timeTelevision system detailsExposure controlAccelerometerHorizon
A method and system for determining camera positioning information from an accelerometer mounted on a camera. The accelerometer measures the orientation of the camera with respect to gravity. Orientation measurement allows user interface information to be displayed in a “right side up” orientation on a viewfinder for any camera orientation. Alternatively, an artificial horizon indicator may be displayed in the viewfinder. The accelerometer may also measure camera movement. Camera movement information together with camera orientation can be used to determine camera usage. Additionally, camera movement information can be used to determine a minimum shutter speed for a sharp picture.

Sensor aided video stabilization
InactiveUS20130107066A1Eliminate unintentional tremorEliminate shakingTelevision system detailsColor television detailsGyroscopeImaging processing
Techniques described herein provide a method for improved image and video stabilization using inertial sensors. Gyroscopes, accelerometers and magnetometers are examples of such inertial sensors. The movement of the camera causes shifts in the image captured. Image processing techniques may be used to track the shift in the image on a frame-by-frame basis. The movement of the camera may be tracked using inertial sensors. By calculating the degree of similarity between the image shift as predicted by image processing techniques with shift of the device estimated using one or more inertial sensor, the device may estimate the portions of the image that are stationary and those that are moving. Stationary portions of the image may be used to transform and align the images. For video stabilization, the realigned images may be combined to generate the video. For image stabilization, the realigned images may be either added or averaged to generate the de-blurred image.

A motion vector detection circuit detects a motion vector from a video signal and a one-frame delayed video signal. An interpolation video signal generation circuit uses this detected motion vector to generate an interpolation video signal which is interpolated between frames. Further, two time base emphasizing circuits respectively use a video signal of a preceding frame to perform time base emphasis with respect to the video signal and the generated interpolation video signal. The video signal and the interpolation video signal subjected to time base emphasis are written in a time-series conversion memory. Furthermore, alternately reading the interpolation video signal and the video signal in the mentioned order with a frequency which is double a write frequency can obtain an output video signal having a doubled frame frequency.
