1. An image capture device comprising:

  • an infrared light source configured to illuminate an object with infrared light; and

    a solid-state image capture device including first pixels and second pixels adjacent to the respective corresponding first pixels, the first and second pixels being arranged in a matrix,whereinthe solid-state image capture device includesa photoelectric conversion unit configured to convert incident light from the object into signal charge,a read electrode configured to read the signal charge from the photoelectric conversion unit, anda vertical transfer unit including a plurality of electrodes and configured to read all pixels and transfer the signal charge in an upward column direction and a downward column direction, andin the solid-state image capture device, there is a repetition of a first exposure period and a second exposure period during one frame scanning period,during the first exposure period, the signal charge from the first pixel and the signal charge from the second pixel adjacent to the first pixel are added together in the vertical transfer unit to produce first signal charge, andduring the second exposure period, the signal charge from the first pixel and the signal charge from the second pixel adjacent to the first pixel are transferred without being added to the first signal charge in the vertical transfer unit, and are added together in another packet to produce second signal charge.
