摘要： The target follow-up device of the present invention is adapted quickly and reliably to follow up the position of a target which is moving at high speed. It incorporates an imaging sensor having a number of imaging elements, which performs photometry over the photographic field and which outputs input image data. Based upon this imaging sensor output, input image data for the target to be followed up are stored as reference image data by a memory device. Based upon minimum residue calculation between the input image data and the reference image data, the target follow-up device of the present invention determines the position of the target. In this determination operation, the target follow-up device selects at least one color from a plurality of colors contained in common by the input image data and the reference image data, and calculates the minimum residue for the selected color component.

摘要： There is provided an automatic focusing device of a camera which accurately adjusts focus in a short time on the basis of recent and past information created in accordance with a focused object. The position of the object is predicted on the basis of the recent information and past information calculated at predetermined time intervals. It is therefore possible to accurately predict the position of the object in a short calculation time and to reliably determine whether the object is at rest or in motion. During a servo operation, a tracking servo operation does not begin erroneously for an object at rest. Once the tracking servo operation begins, because of hysteresis for determining whether the object is moving, the lens continuously and stably tracks the object. During the tracking servo operation, there is no delay of the time intervals at which the distance between the lens and the object is measured, and a distance moved by the object can be corrected and automatically adjusted. The lens can thus be moved smoothly in response to the movement of the object.
摘要翻译：提供了一种摄像机的自动对焦装置，其基于根据聚焦对象创建的最近和过去的信息在短时间内精确地调整焦点。基于最近的信息和以预定时间间隔计算的过去信息来预测对象的位置。因此，可以在短的计算时间内精确地预测物体的位置，并且可靠地确定物体是静止还是运动。在伺服操作期间，对于静止的物体，跟踪伺服操作不会错误地开始。一旦跟踪伺服操作开始，由于用于确定对象是否正在移动的滞后，镜头连续且稳定地跟踪对象。在跟踪伺服操作期间，测量透镜和物体之间的距离的时间间隔没有延迟，并且可以校正和自动调整由物体移动的距离。因此，透镜可以响应于物体的移动而平滑地移动。

摘要： Guide numbers tgn1, tgn2 as expected light amounts of a main flashlight and a remote flashlight are added for the calculation of an expected illumination amount of each divided photometric region. If there is an over-illuminated region, among the divided photometric regions, in which the expected illumination amount exceeds a proper illumination amount for a subject, the guide numbers tgn 1 and tgn2 are decreased such that of the two flashlights, the one illuminating the over-illuminated region more is given a larger decrease. In this manner, guide numbers gn 1, gn2 for main flash of the main flashlight and the remote flashlight are calculated so as to adjust the expected illumination amount of the over-illuminated region to a proper value.

摘要： An automatic focus state detecting apparatus comprising a detector, a discriminator, and a selector. The detector is capable of focus state detection respectively in a narrow detecting area and a wide detecting area present in the object field. The discriminator detects the relative movement between the apparatus and an object present in the detecting areas. When the relative movement is detected by the discriminator, the selector causes the detector to effect the focus state detection in the wide detecting area.
