发明名称
摘要 An object is to provide a photoelectric conversion device which can correct a difference between a measured light intensity and an actual light intensity, which occurs when output current decreases due to the fact that a strong light is received, and outputs the corrected current. The photoelectric conversion device includes a photoelectric conversion element; a photocurrent output circuit for providing a first current corresponding to the amount of incident light on the photoelectric conversion element; a photocurrent correcting circuit which includes a corrective photoelectric conversion element for providing a second current, the corrective photoelectric conversion element including a light shield film for blocking part of light; a photocurrent adder circuit which includes a circuit for providing a fourth current; and an amplifier circuit including a circuit which amplifies a current corresponding to the sum of the first current and the fourth current and outputs the amplified current.
