Imaging system and imaging device

An imaging device comprising:

• a first pixel;
• a second pixel;
• a first signal line that is coupled to the first pixel;
• a second signal line that is coupled to the second pixel, and is different from the first signal line;
• a first latch that is coupled to the first signal line, and stores a first digital code;
• a second latch that is coupled to the second signal line, is adjacent to the first latch, and stores a second digital code;
• a transfer section that transfers digital codes outputted from the first latch and the second latch;
• and
• a diagnosis section that performs diagnosis processing on a basis of the digital codes transferred from the first latch and the second latch.

An imaging device comprising:

• a plurality of signal lines;
• a plurality of pixels that each applies a pixel voltage to the plurality of signal lines;
• a plurality of converters that is provided corresponding to the plurality of signal lines, each performs AD conversion on a basis of a voltage of a corresponding signal line of the plurality of signal lines to generate a digital code and output the digital code, and sets, to a predetermined digital code, the digital code to be outputted in a first period;
• a processor that performs predetermined processing on a basis of the digital code, and performs diagnosis processing in the first period;
• and
• a transfer section that transfers the digital code outputted from each of the plurality of converters to the processor.
