Each comparator circuit includes a first comparator circuit connected to a first pixel of a first color, a second comparator circuit arranged on a column adjacent to the first comparator circuit and connected to a second pixel of a second color, and a third comparator circuit arranged on a column adjacent to the second comparator circuit and connected to a third pixel of the first color. Each comparator circuit compares a pixel signal on a corresponding column with a reference signal changing with time and outputs a comparison signal indicating a different level whether a difference between these signals is smaller or larger than a threshold. The control circuit controls the threshold to change stepwise in order of the first, third, and second comparator circuits."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Photoelectric conversion device and imaging system","description":"A photoelectric conversion device includes pixels arranged to form columns, comparator circuits for respective columns, and a control circuit that controls the comparator circuits.
