Abstract: A dual-camera device is provided. The dual-camera device includes wide and telephoto imaging sections with respective lens/sensor combinations, and a processor. The wide and telephoto imaging sections provide wide image data and telephoto image data, respectively. At least one misalignment error exists between the wide and telephoto imaging sections. The processor generates an output image provided with a smooth transition when switching between a lower zooming factor and a higher zooming factor. The processor warps the wide image data using a portion of the misalignment error to generate base wide image data, and warps the telephoto image data using the remaining portion of the misalignment error to generate base telephoto image data. The processor generates the output image using the base wide image data at the lower zooming factor, and generates the output image using the base telephoto image data at the higher zooming factor.

Abstract: The invention provides a motion prediction method. First, a plurality of candidate units corresponding to a current unit of a current frame is determined. A plurality of motion vectors of the candidate units is then obtained. A plurality of scaling factors of the candidate units is then calculated according to a plurality of respective temporal distances depending on a plurality of reference frames of the motion vectors. The motion vectors of the candidate units are then scaled according to the scaling factors to obtain a plurality of scaled motion vectors. The scaled motion vectors are ranked, and a subset of highest ranking motion vectors are identified to be included in a candidate set. Finally, a motion vector predictor for motion prediction of the current unit is then selected from the candidate units.

Abstract: An electronic apparatus includes at least two camera devices and a processing device. The processing device determines a first distance to a surface formed by the two camera devices and a second distance to the surface in response to detecting an object positioned at a first time by the two camera devices, and determines a third distance from the object positioned at a second time to the surface, wherein the second time is later than the first time, and the third distance is longer than the first distance and shorter than the second distance. Also, the processing device determines a depth in a virtual space corresponding to the object positioned at the second time according to the first distance, the second distance, and the third distance.
