摘要： In a automatic focussing camera a focusing lens is moved toward the in-focus position while performing a defocus detection while the defocus amount of the photographic lens is large so as to repeatedly judge the error of the position of the focusing lens. When the defocus amount is decreased lower than a predetermined value the lens is stopped and further defocus detection is made for effecting an accurate defocus detection. The error of the defocus detection is small partly because the defocus detection is made while the lens is stopped, and partly because the defocus detection is made under such a state that the error is smaller than the predetermined value.
摘要翻译：在自动聚焦照相机中，当摄影镜头的散焦量大时，聚焦透镜朝着对焦位置移动，同时执行散焦检测，以便重复地判断聚焦透镜的位置的误差。当散焦量降低到低于预定值时，透镜停止，并进一步进行散焦检测以实现准确的散焦检测。散焦检测的误差部分是因为在镜头停止时进行散焦检测，部分是因为散焦检测是在误差小于预定值的状态下进行的。

摘要： An auto-focusing system includes a focus condition detector which detects the focus condition based on infrared light. A data producer is provided for producing a deflection signal indicating the difference between an image forming distance for infrared light and that for visible light, due to aberration. In accordance with the detected focus condition and deflection signal, an objective lens is shifted to a position for properly focusing an image of visible light on an image forming plane.

The interchangeable lens comprises, inter alia, a code plate for producing a plurality of digital photographic distance signals representing given discrete photographic distances of the optical system in accordance with the adjustment of the optical system for focusing. Circuit means output a predetermined one of a plurality of inputs, the plurality of outputs including a plurality of conversion coefficients needed for converting the detected amount of defocus into the amount of drive to be effected by the driving means, the conversion coefficients being intrinsic to the interchangeable lens and having values depending upon the discrete photographic distances of the optical system represented by the digital photographic distance signals, respectively.The digital photographic distance signals are applied to the circuit means as the predetermined input to cause the circuit means to output one of the conversion coefficients as the predetermined output, the value of which depends upon the photographic distance of the optical system represented by the one digital photographic distance signal being produced. The output conversion coefficient are transmitted to the camera body.

摘要： A camera system including interchangeable lenses each having a switch to control many functions provided to the camera system. By simply operating one lens switch, the working mode of auto-focusing (AF) functions of the camera system can be changed: single-spot AF/multi-spot AF modes, one-shot AF/continuous AF modes, and focus-locing/non-locking modes. When used with an IC card also attached to the camera body, the lens switch can further control the functions of the camera system added or selected by the IC card.
