    • A timing pulse (DSCEXP signal) that is synchronous with a vertical driving signal (VD) of a CCD is sent from an electronic imaging device (DSC) to a CPU of a silver halide recording device (APS). A CPU of the DSC synchronizes the image-capturing of the CCD and the shutter-operation of the APS when the nth pulse (for example, the second pulse) of the vertical driving signal is generated since a command for exposure timing generated by the full press of a shutter release button is received. When an outside luminance is higher than a reference value and an electronic flash is to be used, there is a time lag for one vertical driving signal between the image-capturing of the CCD and the shutter-operation of the APS.
    • 与CCD的垂直驱动信号(VD)同步的定时脉冲(DSCEXP信号)从电子成像装置(DSC)发送到卤化银记录装置(APS)的CPU。 当由垂直驱动信号的第n个脉冲(例如第二个脉冲)产生时,DSC的CPU将产生CCD的图像拍摄和APS的快门操作同步,因为产生了用于曝光定时的命令 按下快门释放按钮。 当外部亮度高于参考值并且使用电子闪光灯时,CCD的图像拍摄与APS的快门操作之间的一个垂直驱动信号存在时间差。

    • An image displayed on a liquid crystal panel is projected on a projection surface by a projection lens. An optical axis of a projection lens is perpendicular to the projection surface. However, alight emitting optical axis of a distance measurement light and an optical axis of a light receiving lens is inclined with respect to the optical axis of a projection lens, not to be perpendicular to the projection surface. A distance measurement unit is formed by unitizing a light emitting element, a light emitting lens, the light receiving lens, and a light receiving element, and the distance measurement unit is held with the projection lens by a common holder. Even if a surface like a whiteboard which has high reflectivity is used as the projection surface, high accuracy of the distance measurement is kept because diffused light from the light emitting lens, which is regularly reflected from the projection surface, is away from an effective photodetecting region of the light receiving element.
    • 通过投影透镜将显示在液晶面板上的图像投影在投影面上。 投影透镜的光轴垂直于投影面。 然而,远距离测量光的发光光轴和受光透镜的光轴相对于投影透镜的光轴倾斜,而不垂直于投影面。 通过将发光元件,发光透镜,受光透镜和受光元件组合而形成距离测量单元,并且距离测量单元通过公共保持器与投影透镜保持。 即使使用具有高反射率的白板的表面作为投影面,由于从投影面经常反射的来自发光透镜的扩散光远离有效的光电检测,因此保持距离测量的高精度 光接收元件的区域。

    • A distance measuring apparatus includes distance measuring units of the active and passive methods, and a distance-value selecting circuit for selecting and outputting one of distance measurement results obtained from these distance measuring units. When a self-timer mode is set, distance measurement of the active method is inhibited, and distance measurement is executed by only the passive method. When the power supply voltage is lower than a predetermined voltage value at which distance measurement can be properly executed by the active method, distance measurement by the active method is inhibited, and distance measurement is executed by only the passive method. Therefore, erroneous distance measurement can be prevented, and distance measurement having high reliability can be performed.
    • 距离测量装置包括有源和无源方法的距离测量单元和用于选择和输出从这些距离测量单元获得的距离测量结果之一的距离值选择电路。 当设置自拍模式时,禁用活动方法的距离测量,仅通过被动方式进行距离测量。 当电源电压低于通过主动方式可以适当地执行距离测量的预定电压值时,通过主动方法的距离测量被禁止,并且仅通过被动方式执行距离测量。 因此,可以防止错误的距离测量,并且可以执行具有高可靠性的距离测量。

    • A distance measuring apparatus for measuring a distance to an object, which comprises an active distance measuring unit, a passive distance measuring unit, a parameter determining unit, a memory and a distance-value selecting circuit. The memory stores a distance measurement value look-up table and a parameter look-up table. The distance-value selecting circuit outputs an active distance measurement value or a passive distance measurement value as a distance to the object on the basis of first type active and passive distance measurement points picked up from the distance measurement value look-up table and second type active and passive distance measurement points picked up from the parameter look-up table.
