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： A focus detecting device is provided with first and second line sensors and first and second image forming lenses which are located behind a predetermined focal plane of the objective lens to receive the object lights for forming first and second images on the first and second line sensors, respectively. The image signal generated by the first line sensor is divided into a plurality of block signals each consisting of a predetermined number of picture element outputs and each block signal is compared with groups of picture element outputs of the second line sensor, with the groups shifted sequentially, to find a group which best coincides therewith and the distance between the first and second images on the line sensors is calculated in accordance with the shift position of the group thus determined, for calculation of the amount and direction of defocus of the object image on the focal plane. The calculated distance between the first and second images may be corrected in accordance with manual adjustment of adjustable means and magnification data of the first and second images stored in storage means.

摘要： A camera with a multi-zone focus detecting device has an objective lens mounted on a camera. An image formed by the objective lens is divided into a plurality of zones. In each zone, a focusing condition is detected based on the image formed by the objective lens so as to produce a plurality of focusing condition data. Based on the result of the focusing conditions, one zone is selected. Furthermore, a light which has passed through the objective lens is measured separately in each zone so as to produce a plurality of measured light data. Based on a focusing condition data obtained from the selected zone, the objective lens is driven to an infocus condition. When the objective lens is driven to the infocus condition, a measured light data obtained from the selected zone is used for calculating exposure data with which the exposure is controlled.

摘要： An automatic focus adjusting apparatus of a camera having an AF lock function in which driving of a lens is prohibited after detection of an in-focus state comprises determining apparatus for determining whether or not the lens is at the in-focus point and a controller for controlling the camera such that the exposure is not carried out until the lens is driven to the in-focus point when it is determined that the lens is in an out-of-focus state and a shutter release button is pressed. In the case of the object is moving, the lens is kept driven by the movement of the object in response to the operation of the shutter release button even if the in-focus state is once realized and the AF lock is carried out.

摘要： An automatic focus adjusting apparatus for adjusting automatically a focus condition of an objective lens includes a CCD array for receiving light from an object and producing a accumulated charge signal representing the accumulated charge. using the accumulated charge signal it is detected whether or not the brightness of the object is above a predetermined level, and at the same time, the focusing condition of the objective lens is calculated. Using the calculated result, the focusing condition of the objective lens is adjusted in a controlled manner such that: when the brightness of the object is above the predetermined level, the objective lens moves even during the CCD array is operated to carry out the charge accumulation; but when the brightness of the object is below the predetermined level, the CCD array is operated only during when the objective lens is making no movement.
