Imaging device and imaging system

An imaging device comprising:

• a plurality of pixels arranged over a plurality of rows and a plurality of columns,
• wherein each of the plurality of pixels includes
• a first photoelectric conversion unit;
• a second photoelectric conversion unit;
• a third photoelectric conversion unit;
• a microlens that collects light into the first photoelectric conversion unit, the second photoelectric conversion unit, and the third photoelectric conversion unit;
• a first color filter through which a light entering the first photoelectric conversion unit passes;
• a second color filter through which a light entering the second photoelectric conversion unit passes;
• and
• a third color filter through which a light entering the third photoelectric conversion unit passes,
• wherein the first photoelectric conversion unit, the second photoelectric conversion unit, and the third photoelectric conversion unit are arranged in this order in a first direction, and
• wherein a transmittance of the first color filter and a transmittance of the third color filter are different from a transmittance of the second color filter.
