    • PURPOSE:To obtain an exposure value which is free from any effect of the light coming in through an eyepiece, by subtracting the value obtained from the photometric volume of the adverse light in the mirror-up state from the result of operation carried out in the mirror-down state after providing a photodetector at the back of a pentaprism. CONSTITUTION:A photodetector 8 is provided at the back of a pentaprism, and the light volume Lo reaching the detector 8(SBC) with a quick return mirror 3 set down is converted into the voltage volume that received the logarithmic compression through a photometric part 11. Then an operation is carried out between the photometric volume sent from the part 11 in the mirror-down state and the diaphragm and ASA information 12 through an arithmetic part 13. The result of operation is temporarily stored in a storage part 15. On the other hand, the photometric volume of the adverse incident light coming in through an eyepiece 6 is obtained from the volume of light arriving at the detector 8 in the mirror-up state. Thus the value obtained based on the photometric volume of the adverse incident light is subtracted from the result of operation stored temporarily in the part 15 through a subtracting arithmetic part 14 to deliver the value corresponding to the proper exposure volume.
    • 目的:为了获得没有通过目镜进入的光的任何影响的曝光值,通过从在镜像状态中的不利光的光度体积中获得的值从在 在五棱镜背面提供光电检测器后,镜像状态。 构成:在五棱镜的背面设有光检测器8,并将设置有快速反射镜3的检测器8(SBC)的光量Lo转换成通过测光部11接受对数压缩的电压体积 然后,在从倒装状态的部分11发送的测光体与隔膜之间进行操作,并通过算术部13进行ASA信息12.操作结果暂时存储在存储部15中。在 另一方面,通过目镜6进入的不利入射光的光度体积是从在镜像状态下到达检测器8的光量获得的。 因此,通过减法运算部14从暂时存储在部分15中的操作结果中减去基于不利入射光的光度体积获得的值,以递送对应于适当的曝光量的值。

    • PURPOSE: To detect exactly a camera shake, etc. by comparing a ratio of an accumulation quantity of a photodetecting quantity at different positions with a ratio of a photodetecting quantity in a short time.
      CONSTITUTION: Signals AWD corresponding to a photodetecting quantity of photoelectric converting elements 1aW1d are amplified, and thereafter, its difference is detected by differential input type operating materials 6aWc, it is inputted to A/D converters 7aWc, and the outputs of the A/D converters after a prescribed time elapses are pulse-inputted to registers 8aW8c and are held. When signals of exclusive OR gates 9aW9i do not coincide with each other, one of OR gates 10aW10c becomes a high level, and OR gate 11 outputs a signal of a high level. As a result, a ratio of outputs of the photoelectric elements 1aW 1d is compared with values of the shift registers 8aW8c, and a blur can be detected exactly.

    • PURPOSE: To always assure a shift even for driving with a monitor signal, by deciding either one detection mode of a pulse signal in response to the initial state of a monitor signal source.
      CONSTITUTION: A monitor signal is generated from a sliding scan of a brush 4 on a conductor pattern 5. The initial state of this signal generation is detected by an exclusive OR gate 10 and a flip-flop 8. Then the output state deciding mode of the monitor signal is switched to an initial state mode by a counter 11 to prevent the detecting operation to the first output state change of the monitor signal. Then the output state is detected at and after the second change. Thus it is always possible to assure a shift of a prescribed object even in a single monitor signal driving state.
