Abstract:
An imaging device whose dynamic range is broadened is provided. The imaging device includes a pixel including a first photoelectric conversion element and a first circuit including a second photoelectric conversion element. The first circuit switches the operation mode of the pixel to a normal imaging mode or a wide dynamic range mode and switches the operation region of the first photoelectric conversion element to a normal region or an avalanche region in accordance with the illuminance of light with which the second photoelectric conversion element is irradiated. When the illuminance of light with which the first photoelectric conversion element is irradiated is increased, the increase rate of a writing current flowing to the pixel is higher in the avalanche region than in the normal region. However, in the wide dynamic range mode, the increase rate of current can be lowered, and thus the dynamic range can be broadened.

Claim (Index 12):
The imaging device according to  claim 1 , wherein:\n the controller comprises a current mirror circuit, the current mirror circuit is electrically connected to one terminal of the second photoelectric conversion element, and one of a non-inverting input terminal and an inverting input terminal of the comparator circuit.
