A photoelectric conversion apparatus which includes a plurality of sensor chips wherein each sensor chip is arranged into a plurality of unit blocks each having plural photoreceiving elements. A common signal reading line is provided, through which signals are read out from the plurality of photoreceiving elements of the plurality of sensor chips. After sequentially reading out signals from first photoreceiving elements included in each of the plurality of unit blocks in a first sensor chip, and before sequentially reading out signals from photoreceiving elements other than the first photoreceiving elements included in unit blocks of the first sensor chip, signals are read out to the common signal reading line from the photoreceiving elements included in the unit blocks in sensor chips other than the first sensor chip. Thus, a multi-chip type image sensor having a smaller chip size with desired performance is provided. |
