The electronic device includes a first display disposed on a first surface of the electronic device, a second display disposed on a second surface of the electronic device and having at least a portion thereof being unviewable to a user according to a folding state of the electronic device, a memory configured to store instructions, and a processor electrically connected to the first display, the second display, and the memory. The processor is configured to execute the instructions to detect a change in the folding state of the electronic device while displaying a first image on one of the first display or the second display, when the change in the folding state is detected, generate a second image to be displayed on the other of the first display or the second display, while generating the second image, store a snapshot image of the first image in the memory and display the snapshot image on the other of the first display or the second display, and when the second image is generated, display the second image on the other of the first display or the second display instead of the snapshot image. ## Claims ### Claim 1 An electronic device comprising: a housing including a first housing and a second housing; a hinge unit rotatably connecting the first housing and the second housing; a first display disposed on a first side of the first housing and a second side of the second housing; a second display disposed on a second side of the first housing, located at an opposite side of the first side; at least one sensor; a processor; and memory storing instructions that, when executed by the processor, cause the electronic device to: detect, via the at least one sensor, a change in a folding angle of the electronic device while displaying a first image on one of the first display or the second display, when the change of the folding angle is detected, display a snapshot image of the first image on the other of the first display or the second display, and generate a second image based on the first image and a resolution corresponding to the other of the first display or the second display, and when the generation of the second image is completed, display the second image on the other of the first display or the second display instead of the snapshot image. ### Claim 2 (depends on 1) The electronic device of claim 1, wherein the processor is further configured to execute the instructions to: when the change of the folding angle is detected, identify a setting regarding continuity of a running application, and when the setting regarding the continuity of the running application is identified, generate the second image to display on the other of the first display or the second display. ### Claim 3 (depends on 2) The electronic device of claim 2, wherein the processor is further configured to execute the instructions to, when the setting regarding the continuity of the running application is not identified, display a pre-designated screen on the other of the first display or the second display. ### Claim 4 (depends on 2) The electronic device of claim 2, wherein the processor is further configured to execute the instructions to, when the setting regarding the continuity of the running application corresponding to the change of the folding angle is identified, generate the second image to display on the other of the first display or the second display. ### Claim 5 (depends on 1) The electronic device of claim 1, wherein the processor is further configured to execute the instructions to: perform image processing with respect to the snapshot image, and display the image processed snapshot image on the other of the first display or the second display. ### Claim 6 (depends on 1) The electronic device of claim 1, wherein the processor is further configured to: execute the instructions to perform image processing with respect to the second image, and display the image processed second image on the other of the first display or the second display for a pre-set time. ### Claim 7 (depends on 1) The electronic device of claim 1, further comprising: a display controller configured to provide data indicating an image to display on the first display, the second display, or a combination of the first display and the second display, wherein the display controller comprises a write back plane configured to store the snapshot image on the first image in the memory by hooking the data temporarily stored in the display controller. ### Claim 8 (depends on 1) The electronic device of claim 1, wherein the processor is further configured to execute the instructions to, when the change of the folding angle is detected, turn off the one of the first display or the second display and to turn on the other of the first display or the second display. ### Claim 9 (depends on 1) The electronic device of claim 1, wherein the snapshot image is displayed until a new image is generated. ### Claim 10 An electronic device comprising: a housing including a first housing and a second housing; a hinge unit rotatably connecting the first housing and the second housing; a display in which an area facing a user is changed according to a folding angle of the electronic device; at least one sensor; a processor; and memory storing instructions that, when executed by the processor, cause the electronic device to: detect, via the at least one sensor, a change of the folding angle of the electronic device while displaying a first image on a first area of the display, when the change of the folding angle is detected, display a snapshot image of the first image on a second area of the display corresponding to the changed folding state, and generate a second image based on the first image and a resolution corresponding to the second area, and when the generation of the second image is completed, display the second image on the second area of the display instead of the snapshot image. ### Claim 11 (depends on 10) The electronic device of claim 10, wherein the processor is further configured to execute the instructions to: when the change of the folding angle is detected, identify a setting regarding continuity of a running application, and when the setting regarding the continuity of the running application is identified, generate the second image to display on the second area. ### Claim 12 (depends on 11) The electronic device of claim 11, wherein the processor is further configured to execute the instructions to, when the setting regarding the continuity of the running application is not identified, display a pre-designated screen on the second area. ### Claim 13 (depends on 11) The electronic device of claim 11, wherein the processor is further configured to execute the instructions to, when the setting regarding the continuity of the running application corresponding to the change of the folding angle is identified, generate the second image to display on the second area. ### Claim 14 (depends on 10) The electronic device of claim 10, wherein the processor is further configured to: execute the instructions to perform image processing with respect to the snapshot image, and display the image processed snapshot image on the second area, and wherein the image processing is at least one of scaling, rotation, or blurring. ### Claim 15 (depends on 10) The electronic device of claim 10, wherein the processor is further configured to execute the instructions to: perform image processing with respect to the second image, and display the image processed second image on the second area for a pre-set time. ### Claim 16 (depends on 10) The electronic device of claim 10, further comprising: a display controller configured to provide data indicating an image to display on the display, wherein the display controller comprises a write back plane configured to store the snapshot image regarding the first image in the memory by hooking the data temporarily stored in the display controller.
