Claim 5:
6. The imaging apparatus according to claim 3, wherein
the first light receiving element and the second light receiving element respectively receive the first detection light and the second detection light at any temperature, and
the transmittance calculator
acquires reference characteristic data indicating a relationship between an output value of a light receiving element and transmittance at a reference temperature,
calculates a reference output value indicating a transmittance of 100% in the reference characteristic data,
calculates the first output value at the reference temperature based on the first output value at the any temperature, the second output value at the any temperature, and the reference output value, and
calculates the liquid crystal transmittance based on the first output value at the reference temperature and the reference characteristic data.
