    • The present invention provides an ear thermometer that irradiates liquid crystal with backlight without increasing a battery capacity, to make a body temperature displayed with the liquid crystal easily visible even in a dark place. An MCU 1 displays a body temperature measured by a body temperature measuring part (3) on a liquid crystal display part (5), controls, through input/output ports (P1. P2), a backlight emitting part (7) in such a way that the light quantity of the backlight irradiating the liquid crystal display part (5) from the backlight emitting part (7) is maximized for a first predetermined time, controls the backlight emitting part (7) in such a way that the quantity of the backlight keeps, for a second predetermined time that follows the first predetermined time, a predetermined level that is lower than the maximum, and controls the backlight emitting part (7) in such a way that the quantity of the backlight is zeroed after the second predetermined time elapses.

    • An infrared ear thermometer includes a detector head housing (12), a heat sink (30), a recess formed in the heat sink (30), a thermopile sensor (40) mounted within the recess, a thermistor (44), and temperature determination circuitry (14). The recess defines an aperture that limits the field of view of the thermopile sensor (40). The thermal capacities, the conductivities of the heat sink (30), and the thermopile sensor (40) are selected so that the output signal of the thermopile sensor (40) stabilizes during a temperature measurement. A method of determining temperature using the ear thermometer takes successive measurements, stores the measurements in a moving time window, averages the measurements in the moving window, determines whether the average has stabilized, and outputs an average temperature. A method of calculating a subject's temperature determines the temperature of a cold junction of the thermopile (40), looks up a bias, and slope of the thermopile (40) based upon the temperature of the cold junction, measures the output of the thermopile (40), calculates the subject's temperature based upon a linear relationship between the output and the subject's temperature. The linear relationship is defined by the bias, and the slope.
