    • A photo-detecting device employed for photo-detecting a storage type photo-sensor which produces information stored therein according to light inputs on the form of signals integrated in a real time and nondestructive manner. Timing for reading out the output of the photo-detecting apparatus by a control circuit which controls on the basis of the output of the photo-detecting apparatus is to be determined according to the output of the photo-detecting apparatus when the photo-detecting means stores information corresponding to the light inputs. A period of time after storage is started by the photo-detecting means and before the information is read out by the control circuit is determined during the process of storing the information.
    • 一种光电检测装置,用于根据以实时和非破坏性方式集成的信号的形式的光输入产生存储在其中的信息的存储型光电传感器进行光检测。 根据光电检测装置的输出进行控制的控制电路读出光电检测装置的输出的定时是根据光检测装置的输出来确定的,当光检测装置 存储对应于光输入的信息。 存储之后的时间段由光电检测装置开始,并且在存储信息的过程中由控制电路读出信息之前确定。

    • A distance detecting device in which, with respect to an object whose distance is to be detected, the images of a first and a second field following different lines of sight and containing the object and different in range are scanned while, at the same time, continuous M quantized image element data regarding the first field image and continuous N (N>M) quantized image element data regarding the second field image are obtained and the M image element data regarding the first field image are stored in a first circulation type shift register while the first M image element data of the N image element data regarding the second field image are stored in a second circulation type shift register and the remaining N-M image element data are stored in a third shift register, and the comparison between the stored data of the first and second shift registers during one circulation of said stored data and the relative shift of n bits each of the stored data of the second and third shift registers with respect to the stored data of the first shift register are repeatedly effected to thereby detect the distance to the object, characterized in that in the circulation circuit of the first shift register, bypass means is provided for delaying one circulation of the stored data of the first shift register by n bits relative to one circulation of the stored data of the second shift register and the stored data of the first shift register are circulated through the bypass means, whereby for each one circulation of the stored data of the first shift register, the stored data of the second shift register are shifted by n bits each relative to the stored data of the first shift register.
    • 一种距离检测装置,其中,对于要检测距离的物体,扫描不同视线并包含物体并且在不同范围内的第一场和第二场的图像,同时, 获得关于关于第二场图像的第一场图像和连续M(N> M)个量化图像元素的连续M量化图像元素数据,并且关于第一场图像的M个图像元素数据被存储在第一循环型移位寄存器 而关于第二场图像的N个图像元素数据的第一M个图像元素数据被存储在第二循环型移位寄存器中,并且剩余的NM图像元素数据被存储在第三移位寄存器中,并且存储的数据 在所述存储的数据的一个循环期间的第一和第二移位寄存器以及第二和第三移位寄存器的每个存储的数据的n位的相对移位 相对于第一移位寄存器的存储数据重复进行,从而检测到对象的距离,其特征在于,在第一移位寄存器的循环电路中,提供旁路装置,用于延迟所存储的数据的一个循环 第一移位寄存器相对于第二移位寄存器的存储数据的一个循环和第一移位寄存器的存储数据的n个位循环通过旁路装置循环,由此对于第一移位寄存器的存储数据的每个循环 ,第二移位寄存器的存储数据相对于第一移位寄存器的存储数据分别移位n位。
