    • A camera including a first and second luminance detector, a distance detector and a calculator. The first luminance detector, having a first spectral sensitivity and receiving light from a larger region of a photographing view, generates a first luminance information. The distance detector, having a second spectral sensitivity and receiving light from a smaller region of the photographing view, generates a distance information concerning a distance to an object. The second luminance detector generates a second luminance information based on the received light of the distance detector. The calculator calculates a control luminance value for exposure control based on the first luminance information and the second luminance information when the first luminance information is above a predetermined threshold value. In addition, the calculator calculates a control luminance value based on the first luminance information when the first luminance information is below the predetermined threshold value.
    • 一种照相机,包括第一和第二亮度检测器,距离检测器和计算器。 具有第一光谱灵敏度并且从拍摄视图的较大区域接收光的第一亮度检测器产生第一亮度信息。 具有第二光谱灵敏度并且从摄影视图的较小区域接收光的距离检测器产生关于与物体的距离的距离信息。 第二亮度检测器基于距离检测器的接收光产生第二亮度信息。 当第一亮度信息高于预定阈值时,计算器基于第一亮度信息和第二亮度信息计算用于曝光控制的控制亮度值。 此外,当第一亮度信息低于预定阈值时,计算器基于第一亮度信息计算控制亮度值。

    • A control apparatus of an electric power steering apparatus capable of firmly detecting an abnormality of a torque detection value, caused by a drift occurred in a torque sensor and by a connector contact resistor, with a simple arrangement. A current supplied from a power supply flows through a potentiometer (3A) of a torque sensor (3), this current is supplied to a current detecting resistor (13g), a drift occurred in the torque sensor (3) is detected by a voltage across terminals of this resistor, the detected drift detection voltage V.sub.is is read in a microcomputer (21), and the drift detection voltage V.sub.is is compared with a set value to judge as to whether or not the drift is present within a normal range. The torque sensor is constructed of a main potentiometer (3.sub.M) and a sub-potentiometer (3.sub.S). A change amount .DELTA.V.sub.M is calculated from a difference between a presently detected value and a previously detected value of the torque detection voltage V.sub.2M of the main potentiometer. Also, a change amount .DELTA.V.sub.S as to the sub-potentiometer is similarly calculated. An abnormality of the torque detection value is judged in response to these change amounts .DELTA.V.sub.M and .DELTA.V.sub.S.
