In a case where the detection unit detects a predetermined operation for changing a display appearance of the image data to be displayed, the transmission control unit performs control such that information of an amount of change resulting from the predetermined operation is transmitted to the display control apparatus. ## Claims ### Claim 1 An information processing apparatus that transmits image data to be displayed in a display unit to a display control apparatus, the information processing apparatus comprising: at least one processor; a communication interface; wherein the at least one processor functions as a transmission control unit and a detection unit, wherein the transmission control unit performs control such that the image data to be displayed is transmitted to the display control apparatus via the communication interface; and the detection unit detects an operation performed on the information processing apparatus, wherein in a case where the detection unit detects a predetermined operation for changing a display appearance of the image data to be displayed, the transmission control unit performs control such that information of an amount of change resulting from the predetermined operation is transmitted before transmission of the image data to be displayed, to the display control apparatus via the communication interface. ### Claim 2 (depends on 1) The apparatus according to claim 1, wherein the predetermined operation includes an operation for scrolling the image data to be displayed, and the transmission control unit performs control such that an amount of movement resulting from the scrolling operation is transmitted as the information of the amount of change. ### Claim 3 (depends on 1) The apparatus according to claim 1, wherein the predetermined operation includes an operation for enlarging or reducing the image data to be displayed, and the transmission control unit performs control such that an enlargement ratio or a reduction ratio resulting from the operation for enlargement or reduction is transmitted as the information of the amount of change. ### Claim 4 (depends on 1) The apparatus according to claim 1, wherein in a case where the amount of change is greater than a predetermined value, the transmission control unit performs control such that new image data to be displayed is transmitted. ### Claim 5 (depends on 4) The apparatus according to claim 4, wherein in a case where the new image data to be displayed is transmitted, the transmission control unit performs control such that a difference between image data that has been transmitted to the display control apparatus and image data that is being displayed is transmitted. ### Claim 6 (depends on 1) The apparatus according to claim 1, wherein in a case where the predetermined operation has not been performed for a predetermined time period, the transmission control unit performs control such that new image data to be displayed is transmitted. ### Claim 7 (depends on 1) The apparatus according to claim 1, wherein the detection unit detects a touch operation performed on the display unit, and the predetermined operation includes an operation of moving a finger while the finger is touching the display unit. ### Claim 8 (depends on 1) The apparatus according to claim 1, wherein the detection unit detects a touch operation performed on the display unit, and the predetermined operation includes an operation of moving a plurality of fingers while the fingers are touching the display unit. ### Claim 9 (depends on 1) The apparatus according to claim 1, wherein the information processing apparatus is a mobile phone. ### Claim 10 (depends on 1) The apparatus according to claim 1, wherein the information processing apparatus is a tablet terminal. ### Claim 11 (depends on 1) The apparatus according to claim 1, wherein the display control apparatus is a projector. ### Claim 12 A control method of an information processing apparatus that image data to be displayed a display unit to a display control apparatus, the control method comprising: performing control such that the image data to be displayed is transmitted to the display control apparatus via a communication interface; and detecting an operation performed on the information processing apparatus, wherein in a case where a predetermined operation for changing a display appearance of the image data to be displayed is detected in the detection step, control is performed such that information of an amount of change resulting from the predetermined operation is transmitted before transmission of the image data to be displayed, to the display control apparatus via the communication interface. ### Claim 13 A computer-readable storage medium storing a program for causing a computer to execute a control method, of an information processing apparatus that transmits image data to be displayed in a display unit to a display control apparatus, the control method comprising: performing control such that the image data to be displayed is transmitted to the display control apparatus via a communication interface; and detecting an operation performed on the information processing apparatus, wherein in a case where a predetermined operation for changing a display appearance of the image data to be displayed is detected in the detection step, control is performed such that information of an amount of change resulting from the predetermined operation is transmitted before transmission of the image data to be displayed, to the display control apparatus via the communication interface. ### Claim 14 A display control apparatus storing a program for causing a computer of the information processing apparatus to execute a control method of an information processing apparatus that transmits image data to be displayed in a display unit to a display control apparatus, the control method comprising: performing control such that the image data to be displayed is transmitted to the display control apparatus via a communication interface; and detecting an operation performed on the information processing apparatus, wherein in a case where a predetermined operation for changing a display appearance of the image data to be displayed is detected in the detection step, control is performed such that information of an amount of change resulting from the predetermined operation is transmitted before transmission of the image data to be displayed, to the display control apparatus via the communication interface.
