The control unit 103 executes the control program 105A and also functions as the authentication processing unit 103D. When the communication control unit 103A receives the authentication data 27D transmitted from the mobile terminal 21, the authentication processing unit 103D (authentication unit) authenticates the authentication data 27D based on the authentication data 105C stored in the storage unit 105. I do. This authentication is for determining whether or not the portable terminal 21 connected to be wirelessly communicable via the wireless communication unit 47 is an authorized portable terminal 21 allowed to connect to the projector 11. If the authentication is successful, the image data received by the communication control unit 103A from the mobile terminal 21 is displayed. If the authentication fails, the wireless communication with the mobile terminal 21 is disconnected or rejected.
The authentication data 105C is data for authenticating the authentication data 27D received by the communication control unit 103A from the mobile terminal 21. Specifically, the authentication data 105C is a serial number of the mobile terminal 21 that permits connection or a mobile phone that permits connection. This is an authentication code shared between the terminal 21 and the projector 11. In this example, the authentication processing unit 103D determines that the authentication is successful when the authentication data 27D received by the communication control unit 103A matches the authentication processing unit 103D. It is also possible to store the serial number or the like of the mobile terminal 21 whose connection is refused as the authentication data 105C. In this case, if the authentication data 27D received by the communication control unit 103A matches the authentication data 105C, the authentication is performed. The processing unit 103D determines that the authentication has failed.

The authentication processing unit 103D can also perform authentication by taking into account the elapsed time measured by the function of the control unit 103 and the current date and time.
For example, if the authentication data 105C is associated with the serial number of the portable terminal 21 that permits connection with the projector 11 and includes information that specifies the time zone and day of the week when connection is permitted, the authentication processing unit 103D determines that the mobile terminal 21 is successfully authenticated only in the designated time zone and day of the week.

  The authentication processing unit 103 </ b> D has a function of detecting the date and time of connection for each portable terminal 21 and the accumulated value of the connected time and storing the detected value in the storage unit 105. If this function is used, the connection time for each portable terminal 21 can be managed. In addition, when the authentication data 105C includes information specifying the number of times and the time that each mobile terminal 21 can be connected, the authentication processing unit 103D displays the number of connections and the connection time stored for each mobile terminal 21. If the accumulated value exceeds the number of times or time specified by the authentication data 105C, authentication can be performed so as to refuse subsequent connections. In this case, the connectable number of times or time can be set as a value per day, per month or per year. Furthermore, when the authentication data 105C includes information such as a serial number for identifying the mobile terminal 21, information that can identify the user who uses the mobile terminal 21 in association with the information such as the serial number (user ID or Name). In this case, when the authentication processing unit 103D authenticates the mobile terminal 21, the user ID and name of the user who uses the mobile terminal 21 can be specified, so that the user ID and name are projected by the projection unit 3, It is possible to count the number and time of connection in association with the user ID and name, and project the count value.
