1. An imaging apparatus comprising:
a liquid crystal panel configured to adjust light transmittance;
a light emitting element configured to apply detection light;
a first light receiving element configured to receive first detection light transmitted through the liquid crystal panel in the detection light, and to output a first output value related to a light amount of the first detection light;
a second light receiving element configured to receive second detection light not transmitted through the liquid crystal panel in the detection light, and to output a second output value related to a light amount of the second detection light;
a transmittance calculator configured to calculate a liquid crystal transmittance of the liquid crystal panel based on the first output value and the second output value; and
an imaging element configured to image imaging light transmitted through the liquid crystal panel.
