Patent ID: 7176945

Claim:
An image processor, comprising: (a) a memory operable to store in real time a series of images of a location captured by an imaging device over time, the captured series of images at least partially including a target that is subject to move within the captured series of images from one point in the time to another point in the time; (b) a detector operable to detect the target and a quantitative value of a movement component thereof by detecting differences between features of the captured series of images at a first point in the time and at a second point in the time; (c) an image generator operable to generate an object image representing a predetermined object so that a color of a predetermined portion of the object image varies according to the detected quantitative value of the movement component of the target, the image generator being further operable to generate a combined image from the object image and an image from the captured series of images; and (d) an output operable to output in real time a signal representing the combined image at the location captured in the series of images.
