An imaging system disables pixel integration for images within frames that are identified as moving while enables pixel integration for images that are not moving. The system may implement a frame-averaging type of integration or recursive types of frame integration, or may refrain from performing frame integration. On a pixel-by-pixel basis, the system may compare a pixel from frame memory with a corresponding pixel of an input frame and may disable pixel integration for the pixel when a difference between the compared pixels exceeds a threshold. One of the integration processes may be performed on the pixels when the difference does not exceed the threshold. When frame integration is disabled or de-selected (e. g. , for pixels having motion), the frame memory may be bypassed and a self-integration may be performed with corresponding pixels from a current frame effectively resulting in no integration. Some embodiments may use multiple thresholds, and may use different integration algorithms depending on conditions within a scene.

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.
