[Solution] A control device including: a determination unit configured to determine whether a touch-and-movement operation is valid across a valid area in which a touch operation on a display unit is treated as valid and an invalid area in which the touch operation is treated as invalid on a basis of whether a start point of the touch-and-movement operation is located within the valid area. ## Claims ### Claim 1 A control device comprising: a determination unit configured to determine whether a touch-and-movement operation is valid across a valid area in which a touch operation on a display unit is treated as valid and an invalid area in which the touch operation is treated as invalid on a basis of whether a start point of the touch-and-movement operation is located within the valid area. ### Claim 2 (depends on 1) The control device according to claim 1, wherein the determination unit, in a case where the start point of the touch-and-movement operation is located within the valid area, determines that the touch-and-movement operation is valid. ### Claim 3 (depends on 1) The control device according to claim 1, wherein the determination unit, in a case where the start point of the touch-and-movement operation is located within the invalid area, determines that the touch-and-movement operation is invalid. ### Claim 4 (depends on 1) The control device according to claim 1, wherein the determination unit, in a case where the start point of the touch-and-movement operation is located within the invalid area, determines that only an operation after movement of a touch position from the invalid area to the valid area among the touch-and-movement operations is valid. ### Claim 5 (depends on 1) The control device according to claim 1, wherein the invalid area is divided into a first invalid area that is adjacent to the valid area and a second invalid area that is not adjacent to the valid area, the determination unit, in a case where the start point of the touch-and-movement operation is located within the second invalid area, determines that the touch-and-movement operation is invalid, and the determination unit, in a case where the start point of the touch-and-movement operation is located within the first invalid area, the determination unit determines that only an operation after movement of a touch position from the first invalid area to the valid area among the touch-and-movement operations is valid. ### Claim 6 (depends on 1) The control device according to claim 1, further comprising: an area setting unit configured to set the valid area and the invalid area on the display unit on a basis of presence or absence of detection of proximity of an eye to a finder. ### Claim 7 (depends on 6) The control device according to claim 6, wherein the area setting unit, in a case where the proximity of the eye to the finder is detected, sets a predetermined area on the display unit as the valid area and sets an area other than the predetermined area on the display unit as the invalid area. ### Claim 8 (depends on 6) The control device according to claim 6, wherein the area setting unit, in a case where the proximity of the eye to the finder is not detected, sets an entire area of the display unit as the valid area. ### Claim 9 (depends on 1) The control device according to claim 1, wherein the touch-and-movement operation is a drag operation on the display unit. ### Claim 10 (depends on 1) The control device according to claim 1, wherein the touch-and-movement operation is an operation used to specify a position to be focused. ### Claim 11 (depends on 1) The control device according to claim 1, further comprising: an operation position specifying unit configured to specify an operation position corresponding to a touch position being moved by the touch-and-movement operation on a basis of presence or absence of detection of proximity of an eye to a finder. ### Claim 12 (depends on 11) The control device according to claim 11, wherein the operation position specifying unit, in a case where the proximity of the eye to the finder is detected, specifies the touch position being moved as the operation position. ### Claim 13 (depends on 11) The control device according to claim 11, wherein the operation position specifying unit, in a case where the proximity of the eye to the finder is not detected, specifies the operation position on a basis of an operation position corresponding to the start point of the touch-and-movement operation and a positional relationship between the start point of the touch-and-movement operation and the touch position being moved. ### Claim 14 (depends on 11) The control device according to claim 11, wherein the operation position specifying unit, in a case where the presence or absence of the detection of the proximity of the eye to the finder is changed, determines a touch position when the presence or absence of the detection of the proximity of the eye to the finder is changed as an end point of the touch-and-movement operation. ### Claim 15 (depends on 1) The control device according to claim 1, further comprising: a processing control unit configured to execute processing regarding photographing or image reproduction, in a case where the touch-and-movement operation is determined as valid by the determination unit, on a basis of the touch-and-movement operation. ### Claim 16 (depends on 15) The control device according to claim 15, wherein the processing control unit moves a display position of an operation target of the touch-and-movement operation that is displayed on a finder or the display unit on the basis of the touch-and-movement operation. ### Claim 17 (depends on 16) The control device according to claim 16, wherein the processing control unit changes a moving speed of the operation target of the touch-and-movement operation further on a basis of presence or absence of detection of proximity of an eye to the finder. ### Claim 18 (depends on 15) The control device according to claim 15, wherein the processing control unit causes a to be displayed on a finder or the display unit, the display indicating that validity of a touch operation on the display unit is changed further depending on whether an eye approaches the finder. ### Claim 19 A control method comprising: determining whether a touch-and-movement operation is valid across a valid area in which a touch operation on a display unit is treated as valid and an invalid area in which the touch operation is treated as invalid on a basis of whether a start point of the touch-and-movement operation is located within the valid area. ### Claim 20 A program causing a computer to function as: a determination unit configured to determine whether a touch-and-movement operation is valid across a valid area in which a touch operation on a display unit is treated as valid and an invalid area in which the touch operation is treated as invalid on a basis of whether a start point of the touch-and-movement operation is located within the valid area.
