摘要： The invention provides a tracking apparatus and a tracking method by which an imaging object can be set without any special manual operation by a user. An imaged image is supplied to an imaging object setting section via an imaging object processing section. In the imaging object setting section, a motion detection section calculates a difference value between images of successive two frames and detects a motion of an image based on the difference value. Then, a portion of the image from which the motion is detected is set as an imaging object to be tracked.

摘要： A motion detection system for detecting motion in input images. One of the input images is stored for use as a reference image for motion detection processing. The reference image is updated according to any one of a multiple of possible updating modes. Images input after establishment of the reference image are compared to the reference image and the detection of motion in the input images is based on the comparison. The interval in which motion in the input images is detected is extended according to a predetermined extension time.

摘要： An incorrect operation is prevented from occurring in a tracking system for keeping track of a photographic object and taking a picture of the photographic object. When a body which is most likely to be recognized incorrectly as a photographic object exists, pan/tilt driving is carried out on a lens block employed in the tracking system so that an optical axis of the lens block is brought into the range of an angle set as an allowed-drive range. By doing so, the lens block will never take a picture of the body. As a result, an incorrect operation can be prevented from occurring due to incorrect recognition of the body as a photographic object.

摘要： A video camera system can track or follow the moving object without influence by other objects outside the desired image. Detection feature patterns are formed after brightness and hue frequency feature data is obtained on the basis of image information of the detection measurement frame. The position of the detection measurement frame having a feature pattern with the largest similarity to the standard feature pattern obtained from the standard measurement frame is determined. An imaging condition of a camera is controlled on the basis of the position information of the detection measurement frame.

摘要： A video camera system can suitably track a moving object without influence of other objects outside the desired image. Detection feature patterns are formed after brightness and hue frequency feature data are obtained on the basis of image information of the detection measurement frame. The position of detection measurement frame having a feature pattern with the largest similarity to the standard feature pattern obtained from the standard measurement frame is determined. An imaging condition of a television camera is controlled on the basis of the position information of the detection measurement frame in order to attain a video camera system enabling to suitably track the object motion. Further, a video camera system can obtain a face image of constantly a same size with a simple construction. An area of the face image on the display plane is detected as the detected face area, and by comparing this with a standard face area, zooming-processing is performed such that the difference becomes 0. Thus, it is unnecessary to use the method of a distance sensor, etc., and a video camera system with a simple construction can be obtained.
