Abstract: An imaging device includes: a solid-state imaging element having a plurality of pixel cells arranged in a matrix; and a signal processing part configured to process a detection signal outputted from each of the pixel cells. The pixel cells each include an avalanche photodiode and output a voltage corresponding to a count number of photons received by the avalanche photodiode as the detection signal. The signal processing part includes a variation calculation part configured to calculate a variation between the pixel cells in the detection signal outputted from each of the pixel cells, and a correction calculation part configured to correct the detection signal outputted from each of the pixel cells, on the basis of the variation calculated by the variation calculation part.

Abstract: An imaging device includes a photoelectric converter generating signal charge; a charge storage region storing the signal charge; a first transistor having a gate coupled to the charge storage region; a second transistor having a source and a drain; and voltage supply circuitry supplying voltages varying with time. An output of the first transistor is fed back to the second transistor and is supplied to the charge storage region. A reset operation for discharging the signal charge in the charge storage region includes a first reset operation and a second reset operation. In the first reset operation, the second transistor changes from an OFF state to an ON state and then changes to an OFF state. In the second reset operation, the voltage supply circuitry supplies the voltages to a gate of the second transistor so that the second transistor gradually changes from an OFF state to an ON state.

Abstract: A socket includes a first base member that includes a module mount unit allowing a module including an imaging device and an object to be placed thereon and an electric connector that electrically connects the imaging device to an external apparatus, a second base member having an opening, and an engagement unit that causes the first base member to be engaged with the second base member under a condition that the module placed on the module mount unit is sandwiched by the first and second base members. When the first base member is engaged with the second base member by the engagement unit under a condition that the module placed on the module mount unit is sandwiched by the first base member and the second base member, the electric connector is electrically connected to the imaging device, and the object receives illumination light from a light source through the opening.

Abstract: An imaging system includes: an image sensor sensitive to ultraviolet light and visible light; a lens configured to focus light from a subject onto the image sensor; and an image processor configured to process image signals output from the image sensor. The image processor obtains the difference between image signals A1 and A2 output from the image sensor at times t1 and t2, respectively. If the differential signal A3 is greater than or equal to a predetermined value, the image processor determines that light from the subject contains the ultraviolet light, and generates an image signal CI based on the differential signal A3.
