    • A compact image pickup device with high sensitivity is provided, which is suitable for a spatial information detecting apparatus. The image pickup device has a plurality of image pickup units (U1) arranged on a semiconductor substrate. Each of the image pickup units (U1) has a light receiving array of photoelectric conversion elements (Px) for generating electric charges corresponding to a received-light amount, a transfer array (Y1) of charge transfer elements (Py), an accumulation array (Z1) of charge accumulation elements each having a greater charge storage capacity than a saturation charge amount of the photoelectric conversion element, and a charge-amount adjusting portion (D4) configured to determine an amount of undesired electric charges to be separated from the electric charges generated by each of the photoelectric conversion elements. The transfer array and the light receiving array (X1) are arranged in a line in a vertical direction (Dv). The accumulation array (Pz) is disposed adjacent to the transfer array (Py) in a horizontal direction (Dh).
    • 提供了一种具有高灵敏度的紧凑型图像拾取装置,其适用于空间信息检测装置。 图像拾取装置具有布置在半导体衬底上的多个摄像单元(U1)。 每个图像拾取单元(U1)具有用于产生对应于接收光量的电荷的光电转换元件(Px)的光接收阵列,电荷转移元件(Py)的传输阵列(Y1),累积阵列 (Z1),每个电荷累积元件具有比所述光电转换元件的饱和电荷量更大的电荷存储容量;以及电荷量调节部(D4),被配置为确定与所述光电转换元件分离的不需要的电荷的量 由每个光电转换元件产生的电荷。 传送阵列和光接收阵列(X1)沿垂直方向(Dv)排列成一行。 累积阵列(Pz)在水平方向(Dh)上邻近传送阵列(Py)设置。
