The display controller determines the range to be used to display an image on the mirror surface using information detected by the sensor unit. The information display terminal is a mirror display having a mirror function on a display surface as well as a function of displaying an image or information on an entire surface or a portion of the mirror surface so that it can provide information while keeping convenience as a mirror. ## Claims ### Claim 1 An information display terminal comprising: a member having a mirror surface; an image display device configured to display an image on the mirror surface; a display controller configured to determine a range that the image display device uses to display the image on the mirror surface; and a sensor configured to detect a state of a person located near the mirror surface, wherein the sensor includes a mirroring range calculation unit configured to calculate a range for mirroring a face of the person in the mirror surface as viewed from the person, and the display controller does not display an image in the range for mirroring the face in the mirror surface calculated by the mirroring range calculation unit. ### Claim 2 (depends on 1) The information display terminal according to claim 1, wherein the sensor is configured to detect a facial expression of the person. ### Claim 3 (depends on 1) The information display terminal according to claim 1, wherein the sensor is configured to detect biological information of the person. ### Claim 4 (depends on 1) The information display terminal according to claim 1, wherein the sensor is configured to detect an object touched by a hand of the person. ### Claim 5 (depends on 1) The information display terminal according to claim 1, wherein the sensor is configured to detect a usage status of equipment installed around the information di splay terminal. ### Claim 6 (depends on 1) The information display terminal according to claim 1, wherein the sensor is configured to detect a service situation of a moving vehicle in which the information display terminal is installed. ### Claim 7 (depends on 1) The information display terminal according to claim 1, wherein the sensor is configured to detect whether a time remaining until the moving vehicle arrives at a destination is equal to or less than a threshold. ### Claim 8 An information display terminal comprising: a member having a mirror surface; an image display device configured to display an image on the mirror surface; a display controller configured to determine a range that the image display device uses to display the image on the mirror surface; and a sensor configured to detect a state of a person located near the mirror surface, wherein the sensor is configured to detect whether the person located near the mirror surface is in a first state in which the person stands up, or a second state in which the person is seated, and the display controller is configured to set a first range in the mirror surface for displaying when the sensor detects the first state, and set a second range in the mirror surface for displaying when the sensor detects the second state, the second range including a wider area than the first range. ### Claim 9 An information display terminal comprising: a member having a mirror surface; an image display device configured to display an image on the mirror surface; a display controller configured to determine a range that the image display device uses to display the image on the mirror surface; and a sensor configured to detect a state of a person located near the mirror surface, wherein the sensor is configured to detect whether the person located near the mirror surface is in a first state in which a line of sight of the person is directed to the mirror surface, or a second state in which a line of sight of the person is not directed to the mirror surface, and the display controller is configured to set a first range in the mirror surface for displaying when the sensor detects the first state, and set a second range in the mirror surface for displaying when the sensor detects the second state, the second range including a wider area than the first range.
