A solid-state imaging device comprising a plurality of pixel sets, the plurality of pixel sets comprising: a first pixel set including first through fourth pixels arranged in a 2x2 matrix in a plan view, each of the first through fourth pixels including two photoelectric conversion parts, and a first charge holding part coupled to the two photoelectric conversion parts of all four pixels in the first pixel set; a second pixel set, which is arranged next to the first pixel set, the second pixel set including fifth through eighth pixels arranged in a 2x2 matrix in a plan view, each of the fifth through eighth pixels including two photoelectric conversion parts, and a second charge holding part coupled to the two photoelectric conversion parts of all four pixels in the second pixel set; first through eighth signal lines; wherein the first signal line is coupled to one photoelectric conversion part of the first pixel and one photoelectric conversion part of the fifth pixel; the second signal line is coupled to the other photoelectric conversion part of the first pixel and the other photoelectric conversion part of the fifth pixel; the third signal line is coupled to one photoelectric conversion part of the second pixel and one photoelectric conversion part of the sixth pixel; the fourth signal line is coupled to the other photoelectric conversion part of the second pixel and the other photoelectric conversion part of the sixth pixel; the fifth signal line is coupled to one photoelectric conversion part of the third pixel and one photoelectric conversion part of the seventh pixel; the sixth signal line is coupled to the other photoelectric conversion part of the third pixel and the other photoelectric conversion part of the seventh pixel; the seventh signal line is coupled to one photoelectric conversion part of the fourth pixel and one photoelectric conversion part of the eighth pixel; the eighth signal line is coupled to the other photoelectric conversion part of the fourth pixel and the other photoelectric converstion part of the eighth pixel; of the pixels included in each pixel set (51Gr, 51R), the photoelectric conversion parts of a first exposure pixel are exposed for a first exposure time, and the photoelectric conversion parts of a second exposure pixel are exposed for a second exposure time shorter than the first exposure time; pixel signals generated in the photoelectric conversion parts of the first exposure pixel are output simultaneously; and pixel signals generated in the photoelectric conversion parts of the second exposure pixel are output separately. a first pixel set including first through fourth pixels arranged in a 2x2 matrix in a plan view, each of the first through fourth pixels including two photoelectric conversion parts, and a first charge holding part coupled to the two photoelectric conversion parts of all four pixels in the first pixel set;
