IMAGING SYSTEM AND METHOD WITH INTELLIGENT DIGITAL ZOOMING |
摘要 |
A system and method for zooming an image. In the illustrative embodiment, the system includes a memory for receiving first and second frames of image data; a motion detector for detecting motion in said first or said second frame of image data; and an intelligent zoom system for zooming said first or said second image using a first or a second zoom method based on a detection of motion by said motion detector on a pixel by pixel basis. In the illustrative embodiment, the invention is scene-based, it works on a pixel by pixel basis to determine if a pixel is in motion. It performs motion related zoom for pixels that are affected by motion and conducts cross-field zoom for steady pixels to reduce motion artifacts in zoom mode. Motion may be determined by comparing frame-to-frame pixel value variations to fixed motion threshold(s) or by other algorithms. Independent-field zoom refers to using information from one input field to form a zoomed picture in one associated output field. Cross-field zoom refers to using information from both input fields to form a picture in an output field. The invention may be used with or without zoom interpolation schemes. |
