发明名称 Image tracking apparatus
摘要 An image tracking apparatus includes a video camera 10 for forming an image of a target vehicle and for producing image signals at predetermined time intervals, a first memory 5A for storing image signals, a window setting switch 9 for setting a tracking window on the image signals which were stored in the first memory, a second memory 6A for storing, as reference image signals, the image signals on which the tracking window has been set, a device 11 for detecting whether or not any disturbance has been introduced into the image signals stored in the first memory, and a device 12 for correcting by interpolation the image signals stored in the first memory to reduce the influence of any disturbances. A window updating device updates the tracking window in accordance with a comparison between the reference image signals stored in the second memory and the image signals stored in the first memory, or, when a disturbance has been introduced, in accordance with a comparison between the reference image signals stored in the second memory and the corrected image signals.
