1. A photoelectric conversion device comprising:
- a pixel array including a plurality of pixels arranged in a matrix;
a plurality of blocks including a plurality of pairs, each of the pairs including a comparator provided correspondingly with a column in the pixel array and a memory provided correspondingly with the comparator; and
a block information supply unit that includes a signal line group including a plurality of single lines and is configured to supply block information to the plurality of memories included in the plurality of blocks, the block information being information for distinguishing a signal read from one block among the plurality of blocks and a signal read from another block, wherein the plurality of memories included in one of the plurality of blocks are connected to the signal line group with a pattern different from that for the plurality of memories included in another one of the plurality of blocks.

8. An testing method for a photoelectric conversion device, the photoelectric conversion device including:
-
a pixel array including a plurality of pixels arranged in a matrix; a plurality of blocks including a plurality of pairs, each of the pairs including a comparator provided correspondingly with a column in the pixel array and a memory provided correspondingly with the comparator; and a block information supply unit that includes a signal line group including a plurality of single lines and is configured to supply block information for distinguishing between a signal read from one block among the a plurality of blocks and a signal read from another block, to the a plurality of memories included in the plurality of blocks, wherein the plurality of memories included in one of the plurality of blocks are connected to the signal line group with a pattern different from that for the plurality of memories included in another one of the plurality of blocks, the testing method comprising; comparing a preset expected value with the block information output from the photoelectric conversion device; and determining whether the expected value coincides with the block information. - View Dependent Claims (9)
