Abstract: A personal authentication device includes an infrared ray emitter that emits infrared rays, an infrared camera that captures an infrared image, a status signal outputter that outputs a signal related to a status of the personal authentication device or the status of surroundings of the personal authentication device, and a controller. The controller determines whether or not there is a predetermined change in the status of the personal authentication device or the status of the surroundings of the personal authentication device based on a signal output from the status signal outputter, and when there is the predetermined change, the controller drives the infrared ray emitter and the infrared camera, and performs a three-dimensional face authentication process based on the infrared image captured by the infrared camera.

Abstract: An image display device includes a display that displays at least one of a visible image of an object and a thermal image that represents temperature information of the object by a color and a control unit that controls the display. The control unit causes the display to display one of a first image and a second image. The first image includes the thermal image and the visible image. The second image does not include the visible image but includes a thermal image that is more enlarged as compared to the thermal image in the first image with a numerical value indicating a temperature being superimposed for each predetermined region on the thermal image in the second image.
