摘要： First, a lens is supplied with a power supply LVDD. Then the state of a chip select signal CSL is input, and the processing waits until chip select signal CSL changes from HIGH.fwdarw.LOW.fwdarw.HIGH, that is, until communication preparation on the lens side is completed. When a microcomputer on the lens side is reset and started, the lens side outputs a communication enable signal and thus the time from mounting of the lens to starting of a communication can be reduced. Thus, a lens-exchangeable camera can be provided capable of starting a BL communication in the shortest time depending on the lens.
摘要翻译：首先，镜头配有电源LVDD。然后输入芯片选择信号CSL的状态，并且处理等待，直到芯片选择信号CSL从HIGH-> LOW-> HIGH改变，即直到透镜侧的通信准备完成。当镜头侧的微型计算机复位并启动时，透镜侧输出通信使能信号，因此可以减少从透镜安装到通信开始的时间。因此，可以提供透镜可更换的相机，其能够根据透镜在最短的时间内开始BL通信。

摘要： A lens holding frame holding a lens in a lens barrel is arranged, and a contact member extending therebelow is in friction coupling with a driving axis. By applying driving pulses having such a waveform that includes a moderate rising portion followed by an abrupt falling portion to a piezoelectric element, the holding frame is moved along the direction of the optical axis. An index provided at the holding frame is exposed through a slit of lens barrel, and from the position of the lens on the holding frame, information with respect to the distance to the object is displayed. Detection of the position of the holding frame is performed by a position sensor of ferromagnetic thin film magneto-resistive element type (MR sensor) so as to obtain positional information of the lens on the holding frame based on the detection signal, and the obtained information may be displayed on a liquid crystal or other display portion provided on the lens unit or on a camera body.

摘要： In performing an AF operation in a lens-exchangeable camera, whether or not the DVP reference for a lens mounted (i.e., a position serving as a reference for forward movement of the lens) is infinity, is determined. When the DVP reference is infinite, an AF operation is performed with a decision on subject movement. If the DVP reference is not infinity, an AF operation is performed without a decision on subject movement. Thus, a lens-exchangeable camera can be provided capable of preventing malfunction due to an inappropriate reference position for forward movement of the lens.
摘要翻译：在可透镜相机中执行AF操作时，确定安装的镜头的DVP参考（即，用作镜头的向前移动的基准的位置）是否为无穷大。当DVP参考值无限大时，可以对被摄体移动进行决定，进行AF操作。如果DVP参考值不是无穷远，则在不对被摄体移动进行决定的情况下执行AF操作。因此，可以提供能够防止由于用于镜头向前移动的不适当基准位置而导致的故障的镜头可更换照相机。

摘要： A zoom lens barrel based on the vari-focal optical system includes a zoom cam ring which is supported only rotatably about the optical axis and a focus cam ring which is supported movably only in the axial direction both fitted on a fixed tube inside a lens barrel. For the alteration of the lens focal length, the zoom cam ring is turned to carry out zooming, and for the focusing of an object, the focus cam ring is moved in the axial direction to carry out focusing, thereby preventing the interference between zooming and focusing caused by the movement of the lens sets. A drive mechanism based on a piezo-electric element is used to move the focus cam ring in the axial direction, thereby simplifying the structure and reducing the weight.

摘要： A single-lens reflex camera comprises a taking lens having a zooming optical system, a finder whose angle of view is determined according to a focal length of the taking lens, and an operation member which is manually operated. In the single-lens reflex camera, the focal length of the taking lens is changed by driving the zooming optical system, and the zooming operation is controlled in response to an operation of the operation member so that the focal length of the taking lens is changed in the wide-angle direction by a predetermined amount. An angle of view corresponding to that which is seen before the focal length is changed is displayed within the finder.
