摘要： An automatic focus adjusting device which takes into account a change in the position of the image plane of an object caused by movement of the object during the focus adjusting operation time and makes a lens in focus to the moving object. The position of the image plane of the object after the focus adjusting operation time is foreseeing-calculated with the result of a past focus adjusting operation as a factor, and the current focus adjusting operation time is foreseen in conformity with the foreseeing-calculated value, and the position of the image plane of the object is again foreseeing-calculated with the foreseen time as a factor.

摘要： A focus detection apparatus including an image signal storage type sensor having a plurality of pixels and a storage time control circuit for controlling an intensity level of the sensor, wherein the storage time of an image signal in the sensor is controlled such that the image signal has an optimal level, and focus detection is performed on the basis of the image signal whose storage time is controlled. A pixel output range used for focus detection and a sensor area used for storage time control are changed on the basis of the focus detection result.

摘要： A camera capable of following the movement of an object and constantly maintaining the lens in focus. During a certain period after a focused state is detected, lens drive is forbidden even if a large defocus amount is detected, but the lens is driven during this period if a small defocus amount is detected.
摘要翻译：能够跟随物体运动并且不断地将镜头保持在焦点的照相机。在检测到聚焦状态之后的一定时间内，即使检测到大的散焦量也禁止透镜驱动，但是如果检测到散焦小的物体，则在该期间内驱动透镜。

摘要： This specification discloses an auto-focus apparatus for repetitively effecting focus detection and in-focus judgement and lens driving, and in particular an auto-focus apparatus designed such that in a case where the lens cannot be regarded as being in focus as a result of focus detection, when the deviation from the in-focus point is small, lens driving is effected and in-focus is judged to thereby shorten the time until the judgement of in-focus and when the lens driving when the deviation from the in-focus point is small has not been properly effected, the judgement of in-focus when the deviation from the in-focus point is small is inhibited to thereby enable an accurate in-focus judging operation to be accomplished.
摘要翻译：本说明书公开了一种用于重复地进行焦点检测和对焦判断和透镜驱动的自动对焦装置，特别是设计成在透镜不能被视为聚焦的情况下的自动对焦装置焦点检测时，当与对焦点的偏离小时，进行透镜驱动，并且判断为对焦，从而缩短直到焦点判断为止的时间，以及当透镜驱动偏离对焦时点小的情况未被适当地实现，当与对焦点的偏离小时的对焦判断被抑制，从而能够实现精确的对焦判断操作。

摘要： In a camera where the light metering circuit is supplied with electrical power by pushing the shutter release button to a first stroke, an electrical power supply circuit is constructed in such a way that when the time for which the shutter release button remains at the first stroke exceeds the prescribed period of time, the electrical power supply is stopped, and then when the release button is pushed down further to a second stroke, the electrical power supply starts again.
摘要翻译：在照相机中，通过将快门释放按钮推向第一行程而将光计量电路提供电力，电源电路被构造成使得当快门释放按钮保持在第一行程的时间超过规定的时间段，电源停止，然后当释放按钮进一步向下推动到第二冲程时，电源再次开始。
