an operation detection unit that detects an operation; and an operation data processing unit that causes the wireless communication unit to transmit operation data designating a display position of a pointer to the projector, when the projector displays the pointer according to an operation of a pointing device based on the operation detected by the operation detection unit. ## Claims ### Claim 1 An electronic apparatus comprising: a communication unit that communicates with a display apparatus; and a processor programmed to cause the communication unit to communicate with the display apparatus to acquire information of the display apparatus; set a setting value based on the information of the display apparatus; detect an operation of a pointing device; cause the communication unit to transmit operation data to the display apparatus based on the operation, the operation data being data for designating a display position of a pointer displayed by the display apparatus according to the operation; and obtain the display position after a movement of the pointer corresponding to the operation based on the setting value. ### Claim 2 (depends on 1) The electronic apparatus according to claim 1, wherein the processor obtains a display position after a movement of the pointer corresponding to the operation, and causes the communication unit to transmit the operation data relating to the movement of the pointer on the display apparatus. ### Claim 3 (depends on 2) The electronic apparatus according to claim 2, wherein the processor obtains the display position after the movement of the pointer corresponding to the operation, based on a setting value of an area in which the display apparatus displays the pointer. ### Claim 4 (depends on 3) The electronic apparatus according to claim 3, further comprising: a memory that stores the setting value of the area in which the display apparatus displays the pointer, wherein the processor stores the setting value in the memory, and obtains the display position after the movement of the pointer corresponding to the operation, based on the setting value stored in the memory. ### Claim 5 (depends on 2) The electronic apparatus according to claim 2, wherein the processor causes the communication unit to transmit the operation data indicating an amount and an orientation of the movement of the display position of the pointer. ### Claim 6 (depends on 2) The electronic apparatus according to claim 2, wherein the processor causes the communication unit to transmit the operation data indicating the display position after the movement of the pointer. ### Claim 7 (depends on 1) The electronic apparatus according to claim 1, wherein: the processor outputs a video to the display apparatus. ### Claim 8 (depends on 1) The electronic apparatus according to claim 1, wherein the processor sets the setting value designating whether the operation data is relative coordinate data or absolute coordinate data. ### Claim 9 (depends on 1) The electronic apparatus according to claim 1, wherein the information of the display apparatus represents the resolution of a display area which is the maximum area where the display apparatus can display. ### Claim 10 (depends on 1) The electronic apparatus according to claim 1, wherein the information of the display apparatus represents the number of pixels of a display area which is the maximum area where the display apparatus can display. ### Claim 11 A display system comprising: a display apparatus; and an electronic apparatus, wherein the display apparatus includes a display unit, a first communication unit that receives operation data transmitted from the electronic apparatus, and a first processor that causes the display unit to display a pointer indicating an operation position of a pointing device, based on the operation data received by the first communication unit, and the electronic apparatus includes a second communication unit that communicates with the display apparatus, a second processor programmed to cause the communication unit to communicate with the display apparatus to acquire information of the display apparatus; set a setting value based on the information of the display apparatus; detect an operation of a pointing device; cause the communication unit to transmit operation data to the display apparatus based on the operation, the operation data being data for designating a display position of a pointer displayed by the display apparatus according to the operation; and obtain the display position after a movement of the pointer corresponding to the operation based on the setting value. ### Claim 12 A control method of an electronic apparatus that communicates with a display apparatus, the method comprising: acquiring information of the display apparatus; setting a setting value based on the information of the display apparatus; detecting an operation; transmitting operation data to the display apparatus based on the detected operation, the operation data being data for designating a display position of a pointer displayed by the display apparatus according to an operation of a pointing device; and obtaining the display position after a movement of the pointer corresponding to the operation based on the setting value.
