perform control so as to display and not rotate the second display element when the still image recording preparation operation or the still image recording operation is performed; and perform control so as to rotate and display the second display element when the still image recording preparation operation and the still image recording operation are not performed. ### Claim 8 (depends on 1) The display control apparatus according to claim 1, wherein the instructions, when executed by the one or more processors, further cause the display control apparatus to: perform a moving image recording operation; perform control so as to display and not rotate the second display element when the moving image recording operation is performed; and perform control so as to rotate and display the second display element when the moving image recording operation is not performed. ### Claim 9 (depends on 1) The display control apparatus according to claim 1, wherein the instructions, when executed by the one or more processors, further cause the display control apparatus to: perform focus control; perform control so as to display and not rotate the second display element when the performed focus control is terminated; and perform control so as to rotate and display the second display element when the termination of the focus control is released. ### Claim 10 (depends on 1) The display control apparatus according to claim 1, wherein the instructions, when executed by the one or more processors, further cause the display control apparatus to: detect object regions from the captured image; decide any one of the detected object regions to be the specific region; accept a manual focus operation from a user; and display the first display element in a position of the specific region when the manual focus operation is performed during the detection of the object regions. ### Claim 11 (depends on 10) The display control apparatus according to claim 10, wherein the first display element is a frame displayed in the decided object region, and wherein the instructions, when executed by the one or more processors, further cause the display control apparatus to change a shape of the frame when the detection of the object regions is performed. ### Claim 12 (depends on 1) The display control apparatus according to claim 1, further comprising a touch detector configured to detect a touch operation to the display unit, wherein the instructions, when executed by the one or more processors, further cause the display control apparatus to determine whether or not to rotate and display the second display element each time the touch operation is detected by the touch detector. ### Claim 13 (depends on 1) The display control apparatus according to claim 1, wherein the instructions, when executed by the one or more processors, further cause the display control apparatus to set whether or not to rotate and display the second display element. ### Claim 14 (depends on 1) The display control apparatus according to claim 1, wherein the first display element is a frame superimposed on the captured image and displayed in the specific region. ### Claim 15 (depends on 1) The display control apparatus according to claim 1, wherein the second display element includes a plurality of indexes that indicate a focusing state in the specific region in which the first display element is displayed, the plurality of indexes include at least a first index and a second index that indicate a focusing degree based on their display positions in relation to each other and a third index indicating an in-focus position, and indicate that an object indicated by the first display element is in focus as a result of the first index and the second index being joined together in a position indicated by the third index. ### Claim 16 (depends on 15) The display control apparatus according to claim 15, wherein the instructions, when executed by the one or more processors, further cause the display control apparatus to: perform control so as to change a display distance between the first index and the second index according to the focusing degree;
