Abstract: A light sensor includes a photoelectric conversion layer and a long-pass filter that is disposed above the photoelectric conversion layer. The photoelectric conversion layer has a spectral sensitivity characteristic having a first peak at a first wavelength that is longer than a cut-on wavelength of the long-pass filter, and a spectral sensitivity of the photoelectric conversion layer at the cut-on wavelength is greater than or equal to 0% and less than or equal to 50% of a spectral sensitivity of the photoelectric conversion layer at the first wavelength.

Abstract: An imaging device 100 includes a pixel array PA. A first period, a third period, and a second period appear in this order in a first frame. During the first period, pixel signal readout is performed on a first row in the pixel array PA. During the second period, pixel signal readout is performed on a second row in the pixel array PA. Each of the first period and the second period is a high-sensitivity exposure period. The third period is a low-sensitivity exposure period.

Abstract: An imaging device includes a photoelectric converter including first and second electrodes, a photoelectric conversion layer therebetween, and a hole-blocking layer between the first electrode and the photoelectric conversion layer; and a signal detection circuit electrically connected to the first electrode. The hole-blocking material has an electron affinity lower than both a work function of the first conducting material and an electron affinity of the first photoelectric conversion material. The photoelectric conversion unit is applied with a voltage between the first and second electrodes, and responsive to the voltage within a range from a first voltage to a second voltage, shows that a density of current passing between the first and second electrodes when light is incident on the photoelectric conversion layer becomes substantially equal to that when no light is incident thereon. A difference between the first voltage and the second voltage is 0.5 V or more.

Abstract: A method is for controlling an imaging device that allows switching of an operation mode between a first mode to perform imaging in a first imaging wavelength band and a second mode to perform imaging in a second imaging wavelength band different from the first imaging wavelength band. The method includes: determining whether ambient light includes near-infrared light based on information obtained in the first mode and information obtained in the second mode; and maintaining or changing the operation mode.
