摘要

A photoelectric conversion device includes a pixel region where pixels are arranged to form rows and columns, and a pixel control circuit that supplies control signals to the pixels. The pixel region includes first to fourth regions, a first pixel in the first region and a second pixel in the second region are arranged on different columns on a first row, a third pixel in the third region and a fourth pixel in the fourth region are arranged on different rows on a first column, and the first row on which the first and second pixels are arranged is arranged between rows on which the third and fourth pixels are arranged. The pixel control circuit simultaneously reads out pixel signals of the first and second pixels in a first period and simultaneously reads out pixel signals of the third and fourth pixels in a second period.

說(shuō)明書

Further, on each column of the pixel array of the pixel region 10, a control line 14 and an output line 16 are arranged extending in a second direction intersecting the first direction (the longitudinal direction in FIG. 1). The control line 14 is connected to the pixels P aligned in the second direction to form a signal line common to these pixels P. Further, the output line 16 is connected to the pixels P aligned in the second direction to form a signal line common to these pixels P. Note that the second direction may be referred to as the column direction.

In the present embodiment, a plurality of control lines 14 are arranged in association with a plurality of columns. That is, each of the plurality of control lines 14 is connected to one corresponding column out of the plurality of columns. Further, a plurality of output lines 18 are arranged in association with a plurality of rows. That is, each of the plurality of output lines 18 is connected to one corresponding row out of the plurality of rows. As a modified example of the present embodiment, however, the plurality of control lines 14 may be arranged in association with the plurality of rows, and the plurality of output lines 18 may be arranged in association with the plurality of columns. In such a modified example, the plurality of control lines 12 may be arranged in association with the plurality of columns, and the plurality of output lines 16 may be arranged in association with the plurality of rows.
