1. An electronic device comprising:
a display;
a first imaging circuit that is disposed on a side opposite to a display surface of the display and is configured to capture an image of light in an infrared light wavelength band that has passed through the display;
a second imaging circuit that is disposed on a side opposite to the display surface of the display and is configured to capture an image of light in a visible light wavelength band that has passed through the display;
an electronic processor configured to
correct image data imaged by the second imaging circuit on a basis of image data imaged by the first imaging circuit, and
set a noise removal degree of a pixel region having a luminance change equal to or less than a predetermined reference value in the image data imaged by the second imaging circuit to be higher than a noise removal degree of a pixel region having a luminance change larger than the reference value in the image data.
