Thermal images are widely used to various healthcare applications. However, thermal images captured by smartphone thermal cameras have insufficient accuracy to monitor human body temperature. In this study, we propose an offset correction method for thermal images captured by smartphone thermal cameras. We fully utilize the characteristic which is specific to thermal cameras: the relative temperatures in a single thermal image are highly reliable although the absolute temperatures fluctuate frequently. Our method combines thermal images with a reliable absolute temperature obtained by a wristband sensor based on the above characteristic.
