To provide a photoelectric conversion device that can improve image quality.SOLUTION: A photoelectric conversion device comprises: a photoelectric conversion region in which a signal charge is generated; and a read-out part that, when reading out a signal based on the signal charge generated in the photoelectric conversion region, selectively performs first read-out of reading out the signal by using avalanche multiplication by the signal charge and a second read-out of reading out the signal without causing avalanche multiplication to at least a part of the signal charge.SELECTED DRAWING: Figure 2 【課題】 画質を向上できる光電変換装置を提供することを目的とする。【解決手段】 本発明に係る光電変換装置の１つの側面は、信号電荷を生成する光電変換領域を備え、前記光電変換領域で生成された前記信号電荷に基づく信号を読み出すときに、前記信号電荷によるアヴァランシェ増倍を用いて前記信号を読み出す第１の読み出しと、前記信号電荷の少なくとも一部に対してアヴァランシェ増倍を起こさずに前記信号を読み出す第２の読み出しとを選択的に行う読み出し部を備える。【選択図】 図２
