摘要： An optical system having a deformable mirror is such that, in order to minimize variation of an image position on an imaging plane, or of a ray position, in at least two states where shapes of the deformable mirror are different, first- and lower-order terms of an equation expressing a surface of the deformable mirror are changed in the two states. As a result, an optical system including variable optical-property elements such as a variable focal-length lens, a deformable mirror, and a variable prism, and an optical apparatus having the optical system can be provided which is small in power consumption, noiseless, short in response time, simple in mechanical structure, and low in cost, minimize variation of the image position on the imaging plane, and permits sufficient correction for aberration caused by a shape error or the like.

摘要： Liquid crystal eyeglasses include a detector for detecting a physical quantity which varies with the temperature of the liquid crystal, the orientation of molecules of the liquid crystal or a change in the refractive index of the liquid crystal. The voltage applied to the liquid crystal is controlled in accordance with an output signal from the detector, thus compensating for a change in the refractive index of the liquid crystal which is attributable to a temperature change and maintaining the refractive index constant.

摘要： A video endoscope system adjustable color balance in which a color balance adjusting circuit is adjusted so that a color of an ordinary object image or of a standard object image or of an image caused by a signal delivered from a standard color signal generator which is displayed on a TV monitor for observation is the same, as that displayed on a reference color display means, or so that chromaticity of the color of the standard object image or of the image caused by the signal delivered from the standard color signal generator which is displayed on the TV monitor for observation is measured by a chromaticity measuring device and approached to a standard value, in order to make it possible to eliminate positively color variations and make color balance adjustment with high accuracy in regard to a color picture image displayed on the TV monitor of the video endoscope system. The reference color display is a TV monitor adjusted to display a reference color in predetermined chromaticity through other color balance adjusting circuit connected to an electronic image pickup system, or a standard monitor displaying the color in virtue of an input of a color signal delivered from the standard color signal generator, or a standard color display. An automatic white balance adjustment may also be provided to make adjustment so that, when the standard object is picked up, an input voltage ratio of each color to the color balance adjusting circuit becomes constant. It is desirable that a concave surface with good diffusibility is employed as the standard object and a tip porton of an endoscope is arranged in the concave surface for color balance.

摘要： An optical system is disclosed for an endoscope having a generally tubular distal end in which an objective lens assembly and an image sensor in the form of a solid-state video camera are internally housed so that an image formed by the lens assembly is focussed upon the input or pickup surface of the video camera. The video camera is disposed along or in proximity to the center axis of the distal end of the endoscope and in some instances is oblique with respect to the center axis. The video camera may be positioned in this way due to the provision of a reflecting surface which is angularly disposed in opposing relationship with an input surface of the video camera, and deflection means disposed in front of the lens assembly and within the objective lens assembly, or between the lens assembly and the reflecting surface so that an image formed by the lens assembly can be focussed on the input surface of the video camera.
