    • An internal focus lens includes sequentially from an object side, a first lens group having a positive refractive power; a second lens group having a negative refractive power; and a third lens group having a positive refractive power. The first lens group includes an anti-vibration lens formed by a negative lens that is moved in an orthogonal direction with respect to an optical axis to correct image blur consequent to optical system vibration, and further includes an aperture stop disposed farther on an image side of the first lens group than the anti-vibration lens. The second lens group is moved along the optical axis to perform focusing.
    • 内部聚焦透镜从物体侧顺序地包括具有正折光力的第一透镜组; 具有负屈光力的第二透镜组; 以及具有正屈光力的第三透镜组。 第一透镜组包括由相对于光轴在正交方向上移动的负透镜形成的防振透镜,以校正由于光学系统振动引起的图像模糊,并且还包括更远的图像侧的孔径光阑 的第一透镜组比抗振镜头。 第二透镜组沿着光轴移动以进行聚焦。

    • A display microcomputer displays a menu corresponding to several functions, such as picture-in-picture display and satellite broadcast reception on a mini-viewing screen that is part of the cathode-ray tube picture screen of a television receiver. A remote controller permits selection of different video and audio signal sources and, if the user selects sources that are incompatible or inconsistent, a system controller returns the menu to the condition prior to the incorrect selection. The system controller also controls a display microcomputer in such a way that items on the menu that are inhibited from selection are displayed in halftone. That is, if any inhibited item appears in the menu by a modification of the mode of operation, the display microcomputer is controlled so that the menu is returned to the condition prior to the selection and the inhibited item is displayed in halftone. For example, erroneous operation that would change the reproduced sound of a duplex sound channel while the user is watching a picture reproduced from a video tape recorder is prevented, because the set value for the duplex sound can not be varied by the user.
    • 显示微型计算机在作为电视接收机的阴极射线管画面的一部分的微型观看屏幕上显示对应于诸如画中画显示和卫星广播接收的若干功能的菜单。 遥控器允许选择不同的视频和音频信号源,如果用户选择不兼容或不一致的源,则系统控制器将菜单返回到不正确选择之前的状态。 系统控制器还以这样的方式控制显示微型计算机,使得在半色调中显示禁止选择的菜单上的项目。 也就是说,如果任何禁止的项目通过操作模式的修改出现在菜单中,则控制显示微型计算机,使得菜单返回到选择之前的状态,并且禁止的项目以半色调显示。 例如,由于双方声音的设定值不能被用户改变,因此防止在用户正在观看从录像机再现的图像时改变双面声道的再现声音的错误操作。
