Patent ID: 8072426

Claim:
An interactive device capable of improving image processing comprising: a processing module comprising: an image sensor for generating a plurality of pixel signals corresponding to pixels within one single image; an estimation unit for determining a coordinate of at least one image object within the single image, the at least one image object taken as a set of pixels within the single image having pixel signals with an identical color parameter, the at least one image object having a plurality of pixels, having fewer pixels than the single image and being a subset of the single image, and at least some of the pixel signals in the single image not included in the at least one image object having different color parameters than the set of pixels within the at least one image object; a calculation unit for calculating at least one motion vector based on the plurality of pixel signals, wherein the motion vector is calculated as a motion difference between a reference object and the at least one image object, the reference object being an object in a searching area of a previous image picture or a following image picture with respect to the single image that has a size similar to that of the at least one image object and that has the smallest difference with respect to the at least one image object; and a transmission interface for serially outputting a control signal for the single image based on the motion vector and the coordinate of the at least one image object; and a controller for controlling operation of the interactive device based on the control signal.
