and a display unit configured to display information relating to, of the plurality of display apparatuses, a first display apparatus to which the communication apparatus is to be brought close so that the first display apparatus is detected by that detection unit. ## Claims ### Claim 1 A communication apparatus that is capable of communicating with one of a plurality of display apparatuses, so that an integrated image screen is constituted by combining display image screens of the plurality of display apparatuses, comprising: a communication module configured to communicate with an external device that is close to the communication apparatus within a predetermined range through near field wireless communication; and a display panel configured to display information relating to a first display apparatus of the plurality of display apparatuses, wherein the display panel displays a dialog box including: a layout image that indicates the vertical number of the display image screens and the horizontal number of the display image screens constituting the integrated image screen and that indicates a portion corresponding to a display image screen displayed by the first display apparatus and a portion corresponding to a display image screen displayed by another display apparatus in a manner that the portion corresponding to the display image screen displayed by the first display apparatus can be distinguished from the portion corresponding to the display image screen displayed by the other display apparatus; and a message to prompt a user to make the communication apparatus close to the first display apparatus. ### Claim 2 (depends on 1) The communication apparatus according to claim 1, wherein the plurality of display apparatuses include projection apparatuses each configured to project the display image screen as a projection image screen. ### Claim 3 (depends on 1) The communication apparatus according to claim 1, further comprising a transmitting unit configured to transmit layout information, to the first display apparatus indicating the vertical number of display image screens and the horizontal number of display image screens constituting the integrated image screen, and position information indicating vertical position and horizontal position of the display image screen displayed by the first display apparatus with respect to the integrated image screen. ### Claim 4 (depends on 3) The communication apparatus according to claim 3, wherein the transmitting unit transmits the layout information and the position information through the near field wireless communication. ### Claim 5 (depends on 3) The communication apparatus according to claim 3, wherein the transmitting unit transmits the layout information and the position information through communication that is different from the near field wireless communication and is established using handover information acquired through the near field wireless communication. ### Claim 6 (depends on 5) The communication apparatus according to claim 5, wherein the handover information includes an identifier that identifies the external device with which the near field wireless communication has been established. ### Claim 7 (depends on 1) The communication apparatus according to claim 1, wherein the display panel displays the layout image so that a portion corresponding to a display image screen displayed by any display apparatus of the plurality of display apparatuses for which a setting of the integrated image screen has been set can be distinguished from a portion corresponding to a display image screen displayed by a any display apparatus of the plurality of display apparatuses for which the setting has not been set. ### Claim 8 (depends on 1) The communication apparatus according to claim 1, wherein the communication apparatus has a normal mode in which a setting of the integrated image screen is set to any display apparatus of the plurality of display apparatuses and a cancel mode in which a setting of the integrated image screen set in any display apparatus of the plurality of display apparatuses is cancelled, and the display panel displays a button for transitioning to a mode from the normal mode to the cancel mode in a case where a display apparatus for which the setting of the integrated image screen has been set exists. ### Claim 9 (depends on 1) The communication apparatus according to claim 1, wherein the display panel displays a selection item that enables selection whether any display apparatus of the plurality of display apparatuses is set in a normal mount installation or in a ceiling mount installation. ### Claim 10 (depends on 1) The communication apparatus according to claim 1, wherein the display panel displays an icon indicating a projection manner of display apparatus of the plurality of display apparatuses. ### Claim 11 (depends on 10) The communication apparatus according to claim 10, wherein the icon indicates that the projection manner of the display apparatus is rear projection. ### Claim 12 A control method of a communication apparatus that communicates with one of a plurality of display apparatuses, so that an integrated image screen is constituted by combining display image screens of the plurality of display apparatuses, the method comprising: communicating with an external device that is close to the communication apparatus within a predetermined range through near field wireless communication; displaying information relating to a first display apparatus of the plurality of display apparatuses, wherein the displaying information comprises displaying a dialog box including: a layout image that indicates the vertical number of the display image screens and the horizontal number of the display image screens constituting the integrated image screen and that indicates a portion corresponding to a display image screen displayed by the first display apparatus and a portion corresponding to a display image screen displayed by another display apparatus in a manner that the portion corresponding to the display image screen displayed by the first display apparatus can be distinguished from the portion corresponding to the display image screen displayed by the other display apparatus; and a message to prompt a user to make the communication apparatus close to the first display apparatus. ### Claim 13 A non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method of a communication apparatus that communicates with one of a plurality of display apparatuses so that an integrated image screen is constituted by combining display image screens of the plurality of display apparatuses, the method comprising: communicating with an external device that is close to the communication apparatus within a predetermined range through near field wireless communication; displaying information relating to a first display apparatus of the plurality of display apparatuses, wherein the displaying information comprises displaying a dialog box including: a layout image that indicates the vertical number of the display image screens and the horizontal number of the display image screens constituting the integrated image screen and that indicates a portion corresponding to a display image screen displayed by the first display apparatus and a portion corresponding to a display image screen displayed by another display apparatus in a manner that the portion corresponding to the display image screen displayed by the first display apparatus can be distinguished from the portion corresponding to the display image screen displayed by the other display apparatus; and a message to prompt a user to make the communication apparatus close to the first display apparatus.
