    摘要： A zoom lens is comprised of a fixed barrel, an intermediate barrel coupled to the fixed barrel through helicoid screws, a movable barrel coupled to the intermediate barrel through helicoid screws, a front lens group fixedly held in the movable barrel, and a rear lens group. The position of the front lens group in the optical axis direction is always determined by the axial movement of the intermediate barrel relative to the fixed barrel and the axial movement of the movable barrel relative to the intermediate barrel. The axial position of the rear lens group is determined by the axial movement of the intermediate barrel relative to the fixed barrel and a cam surface formed in an inner periphery of the intermediate barrel. As the axial position of the cam surface within the intermediate barrel changes with the rotational position of the intermediate barrel, the rear lens group moves in the axial direction relative to the intermediate barrel during zooming. But during focusing, a hindering device is activated to hinder the rear lens group from axial movement relative to the intermediate barrel, so that the rear lens group moves by the same amount in the axial direction as the intermediate barrel independently of the cam surface.

    摘要翻译： 变焦镜头包括固定镜筒，通过螺旋螺钉联接到固定镜筒的中间镜筒，通过螺旋螺钉联接到中间镜筒的可动镜筒，固定保持在可动镜筒中的前透镜组以及后透镜组 。 前透镜组在光轴方向的位置总是由中间筒相对于固定筒的轴向运动和可移动筒相对于中间筒的轴向运动确定。 后透镜组的轴向位置由中间筒相对于固定筒的轴向运动和形成在中间筒的内周中的凸轮表面确定。 当中间筒内的凸轮表面的轴向位置随着中间筒的旋转位置而变化时，后透镜组在变焦期间相对于中间筒在轴向方向上移动。 但是在聚焦期间，阻碍装置被激活以阻止后透镜组相对于中间筒的轴向移动，使得后透镜组在独立于凸轮表面的情况下沿与轴承方向相同的量移动相同的量。

    摘要： A water-resistant camera has a lens barrel movable toward and away from a fluid-tight camera body for selecting the position of the lens barrel between wide-angle and telephoto positions. The camera has or can be combined with an automatic air-pressure adjusting mechanism for automatically keeping the air pressure in the inner space of the camera at a substantially constant level irrespective of the position of the lens barrel between the wide-angle position and the telephoto position. Therefore, the lens barrel can smoothly be moved with respect to the camera body upon switching between the wide-angle and telephoto positions.

    摘要： A pseudo zoom camera, which utilizes a film cartridge provided with an information storing device, comprises a taking lens optical system for projecting an object image onto a portion of photographic film, which portion has been pulled out of the film cartridge. The camera also comprises a finder optical system capable of displaying an image of a field angle, which is different from the field angle of the object image formed by the taking lens optical system, in a predetermined region representing an image-recording range. A writing device writes information representing an image range ratio of the image, which is displayed in the predetermined region by the finder optical system, to the object image, the information being written on the information storing device of the film cartridge.

    摘要： A digital camera includes a distortion correction section, which is composed of a focal length determining section, a distortion evaluation section and a correction amount calculating section. The focal length determining section evaluates a focal length at the time of image capture. Based on the focal length, the distortion evaluation section evaluates the magnitude of wide-angle distortion and optical distortion in a captured image. Based on this evaluation, the distortion correction section selects an appropriate coefficient from an optical distortion correction coefficient table or a wide-angle distortion correction coefficient table. Using the selected coefficient, the correction amount calculating section applies a coordinate transform processing to cause positive or negative distortion to the captured image, and corrects the wide-angle distortion or the optical distortion.

    摘要： An image-taking apparatus including an auxiliary light projecting section that is small in size in spite of using multiple projection elements and is capable of performing extensive illumination to a range including parallax while maintaining a certain degree of brightness until reaching a given distance, and a projection module suitable for being loaded on the image-taking apparatus are provided. This apparatus projects light from three light points onto an object in a projection pattern shown in part (b) of FIG. 11 by use of a lens split into three regions. The light from the three light points is formed respectively into three beams by use of each of projecting sections subjected to region splitting, and single light beams out of sets of three beams are projected so as to overlap one another.
