Abstract
A photoelectric conversion device is provided that has high linearity of output current to illuminance and is applicable to illumination sensors. The photoelectric conversion device outputs appropriate current by complementing first current, which is generated in response to incident light, with complementary current. The complementary current is generated based on second current flowing in response to the light. The second current is generated by a device having the same element area as that of a device that generates the first current. When the second current flows, the complementary current is generated based on a direction of the second current and is then added to the first current.
