摘要： Normally, movement of an object to be photographed is detected based upon the brightness information output by a photometric means, and the object to be photographed is followed up. During the exposure process the photometric means cannot perform photometry, and therefore the movement of the object to be photographed during exposure is predicted based upon the movement information for the object to be photographed detected before the start of the exposure process, and the position of the object to be photographed after the conclusion of the exposure process is obtained. When the exposure process has been completed, follow up of the object to be photographed is restarted from the predicted position which has been calculated. By doing this, the object to be photographed is not lost sight of after the exposure process has been completed, and it is possible to continue follow up of the object to be photographed from its predicted position.Further, when follow up of the object to be photographed by the follow up means has become impossible, forcibly the initial state before the start of follow up may be returned to. By doing this, the follow up target object can be again discerned in the initial state etc., and the photographer is able quickly to proceed to the next action.
摘要翻译： 通常，基于由测光装置输出的亮度信息来检测拍摄对象的移动，并且跟踪被拍摄对象。 在曝光处理期间，测光装置不能进行测光，因此根据在曝光处理开始之前检测到的待拍摄对象的移动信息来预测曝光期间拍摄对象的移动， 获得曝光处理结束后拍摄的物体。 当曝光处理完成时，从计算出的预测位置重新开始拍摄对象的跟踪。 通过这样做，在曝光处理完成之后，不会看到要拍摄的对象，并且可以从其预测位置继续跟踪要拍摄的对象。 此外，当后续装置对待拍摄对象的跟踪变得不可能时，强制开始跟踪之前的初始状态可能返回到。 通过这样做，可以在初始状态等再次识别跟踪目标对象，并且摄影师能够快速地进行下一个动作。
