A method is described that includes identifying a set of features of an object, the features being tracked in an image captured by a camera. The method also includes creating a field of vectors for the reference points. The vectors indicate magnitude and direction of change in position of the reference points across more than one frame of the image. The method further includes identifying existence of out of plane movement of the object's features from same radial orientation of the vectors. The method further includes determining an amount of closer/farther movement of the object's features to/from the camera from change in distances between a plurality of the reference points. The method further includes adjusting a position of camera's lens in view of the amount of closer/farther movement of the object's features to keep the camera focused on the object.

A stereo preview apparatus has an auto-stereoscopic display, an input interface, a motion detection circuit, and a visual transition circuit. The input interface receives at least an input stereo image pair including a left-view image and a right-view image generated from an image capture device. The motion detection circuit evaluates a motion status of the image capture device. The visual transition circuit generates an output stereo image pair based on the input stereo image pair, and outputs the output stereo image pair to the auto-stereoscopic display for stereo preview, wherein the visual transition circuit refers to the evaluated motion status to configure adjustment made to the input stereo image pair when generating the output stereo image pair.

The method includes for each current pair of first and second successive video images determining movement between the two images. The determining includes a phase of testing homography model hypotheses on the movement by a RANSAC type algorithm operating on a set of points in the first image and first assumed corresponding points in the second image so as to deliver one of the homography model hypothesis that defines the movement. The test phase includes a test of first homography model hypotheses of the movement obtained from a set of second points in the first image and second assumed corresponding points in the second image. At least one second homography model hypothesis is obtained from auxiliary information supplied by an inertial sensor and representative of a movement of the image sensor between the captures of the two successive images of the pair.
