Abstract

See full text

A semiconductor integrated circuit includes an acquisition unit configured to acquire a value outputted from an infrared sensor in response to an infrared ray received from an object, and a value outputted from a temperature sensor as a function of measured temperature of the infrared sensor; a second-temperature identification circuit configured to identify a second temperature which is a temperature of the object when the temperature of the infrared sensor corresponding to a measured value which is the output value of the infrared sensor, is the first temperature, by referring to the correspondence; a third-temperature identification circuit configured to identify a third temperature which is the temperature of the infrared sensor in outputting the measured value; and a calculation circuit configured to calculate a fourth temperature which is a temperature of the object on the basis of the first temperature, the second temperature, and the third temperature.
