Abstract: A method of motion compensation in a camera may include deriving a motion signal representative of a motion of the camera, processing video frames of a video signal from an image sensor of the camera during a viewfinder mode to derive motion vectors between pairs of frames, and processing the motion signal with a number of combinations of gain and offset factors during the viewfinder mode. The method may also include determining combinations for producing threshold motion vectors, and applying the combination producing the threshold motion vectors for processing the motion signal during a still capture mode to produce a control signal for a motion compensating element for optics of the camera.

Abstract: An optical image stabilization (OIS) system may be used in a camera having an optical system which includes a motion compensating optical element driven by an actuator. The system may include a motion sensor providing a motion signal, a frequency detector for detecting a dominant frequency being that frequency within the motion signal which may produce the most significant motion blurring in the image produced by the camera, and a tunable high-pass filter for filtering the motion signal and supplying the filtered motion signal as an actuator control signal. The tunable high pass filter may be tuned based upon the dominant frequency to a filter characteristic which provides a phase lead substantially canceling a phase lag of the actuator at that frequency.

Abstract: A method of compensating for camera shake includes reading a sequential series of images from an image sensing array, establishing a sharpness value for each of the sequential series of images, and performing an image selection based upon each sharpness value. The sharpness value is calculated for each image of the sequential series thereof during the reading.

Abstract: An image stabilization apparatus includes accelerometers, a proximity sensor and a processor. Each accelerometer determines acceleration along an axis of a plane parallel to a focal plane of an image capture device. The accelerometers output respective acceleration data to the processor. The proximity sensor obtains a measurement of the distance between the focal plane of the image capture device and an object plane. The proximity sensor outputs distance data to the processor. The processor processes the distance data and the acceleration data to produce correction data to correct image data captured during motion of the image capture device.
