The problem of the invention is to suppress image quality deterioration while expanding a dynamic range. In the following manner, an image sensor reads out a signal charge accumulated in image pickup elements from an area sensor wherein a plurality of image pickup elements are arranged in matrix. First, after setting a plurality of different exposure times, these exposure times are separately allotted to each line of the area sensor. Then, the signal charge accumulated in the image pickup element in the allotted exposure time is read out by a line unit of the area sensor. Then, the read out signal charges are composed by a screen unit of the area sensor.
(ZH) 在扩展动态范围的同时抑制图片质量的恶化，按照如下方式，图像传感器从其中以矩阵形式布置多个图像采集元件的区域传感器读出在所述图像采集元件中累积的信号电荷。首先，在设置多种不同的曝光时间之后，将这些曝光时间分别分配到所述区域传感器的各行。然后，以所述区域传感器的行为单位，读出在所分配的曝光时间中在所述图像采集元件中累积的信号电荷。然后，以所述区域传感器的屏幕为单位合成所读出的信号电荷。
