Patent ID: 7231307

Claim:
A temperature measuring apparatus with a temperature correction function, comprising: a two-dimensional thermopile array having a plurality of thermopiles for measuring heat quantity of divided temperature detecting areas, the thermopile array measuring a relative temperature difference between each of the thermopiles and each of the divided temperature detecting areas corresponding to each of the thermopiles in a non-contact manner; a thermal sensor for detecting a temperature of each of the plurality of thermopiles; a calculation portion for calculating a temperature of each of the divided temperature detecting areas based on the temperature obtained by the thermal sensor and the relative temperature difference obtained by the thermopile array; a correction information holding portion for holding correction information on a temperature difference between a known reference temperature of the divided temperature detecting areas and a calculated result outputted from the calculation portion obtained when the divided temperature detecting areas are set to the known reference temperature; and a correction portion for correcting a calculated result of the calculation portion obtained at the time of actual temperature measurement based on the correction information.
