    • A photoelectric sensor device has a two-dimensional arrangement of a multiplicity of unit structures each including a pixel. The sensor device includes a circuit for simultaneously designating a plurality of pixel blocks of any desired sizes at any desired positions on the two dimensional arrangement of unit structures, each pixel block being composed of pixels which are to be actually used. The sensor device also includes a monitor output circuit for outputting, for each of the pixel blocks, at least one monitor output as the representative of the amounts of charges accumulated in the pixels in each of the pixel blocks. The sensor device further includes a circuit which executes the control of accumulation of charges and the control of outputting of the image signals on each of the pixel blocks independently of other pixel blocks. Disclosed also is a focus detection system using the sensor device.
    • 光电传感器装置具有各自包括像素的多个单位结构的二维排列。 传感器装置包括一个电路,用于在单元结构的二维排列上的任何期望位置同时指定任何所需尺寸的多个像素块,每个像素块由实际使用的像素构成。 传感器装置还包括监视器输出电路,用于为每个像素块输出至少一个监视器输出,作为在每个像素块中的像素中积累的电荷量的代表。 传感器装置还包括执行电荷累积控制的电路和独立于其它像素块的每个像素块上输出图像信号的控制。 还公开了使用该传感器装置的焦点检测系统。
