highlight, based on identifying that the adjusted camera magnification using the calculated scroll speed is identical to a camera magnification assigned to one of the plurality magnification icons, the one of the plurality magnification icons,

wherein each of the different magnification-adjustable sections is displayed to have a predetermined number of gradations and to have a different length,

wherein a camera magnification of the specific camera among the plurality of cameras is set to change in response to a user input moving along the gradations and being received on the specific section corresponding to the camera magnification of the specific camera and based on an amount of the number of gradations along which the user input moves,

wherein the number of gradations along which the user input moves is set to increase in proportion to the length of in the specific section

5. The electronic device of claim 1 , wherein the first user input includes one of a hold input, a pinch input, a click input of a volume button, or a gesture input using a bluetooth low energy (BLE) pen, and

wherein the second user input includes one of a pinch input, a click input of the volume button, a gesture input using the BLE pen, a swipe input, a long press input, or a touch input for a specific camera magnification.

6. The electronic device of claim 1 , wherein the instructions, when executed, further cause the processor to:

identify a specific camera magnification selected by the received touch input, and

scroll an indication of the camera magnification on the scrollable UI to match the identified specific camera magnification.

7. The electronic device of claim 6 , wherein the instructions for scrolling the indication of the camera magnification on the scrollable UI to match the identified specific camera magnification are configured to perform a same calculation as the instructions for adjusting the camera magnification by using the calculated scroll speed.

8. A method for adjusting a camera magnification in an electronic device, the method comprising:

identifying a camera magnification of each of a plurality of cameras, included in the electronic device in response to an execution of a camera application of the electronic device, wherein the plurality of cameras have a magnification-adjustable section different from each other;

receiving a first user input for adjusting a camera magnification of a specific camera among the plurality of cameras;

displaying a scrollable user interface (UI) for adjusting the camera magnification in response to receiving the first user input, wherein the scrollable UI includes a specific section corresponding to the specific camera among the different magnification-adjustable sections, and each of the different magnification-adjustable sections is corresponding to a camera magnification of a different camera among the plurality of cameras;

calculating a scroll speed on the displayed scrollable UI by using an acceleration factor corresponding to the received first user input or a second user input received on the specific section corresponding to the specific camera among the different magnification-adjustable sections, and an input speed of the first user input or the second user input;

adjusting the camera magnification of the specific camera among the plurality of cameras by using the calculated scroll speed;

displaying a related camera magnification UI including a plurality of magnification icons based on frequently used camera magnifications;

adjusting the camera magnification in response to receiving a touch input to the related camera magnification UI,

wherein adjusting the camera magnification includes:

identifying the specific camera among the plurality of cameras, and

using the identified specific camera for adjusting a camera magnification; and

highlighting, based on identifying that the adjusted camera magnification using the calculated scroll speed is identical to a camera magnification assigned to one of the plurality magnification icons, the one of the plurality magnification icons,

wherein each of the different magnification-adjustable sections is displayed to have a predetermined number of gradations and to have a different length,

wherein a camera magnification of the specific camera among the plurality of cameras is set to change in response to a user input moving along the gradations and being received on the specific section corresponding to the camera magnification of the specific camera and based on an amount of the number of gradations along which the user input moves,

wherein the number of gradations along which the user input moves is set to increase in proportion to the length of the specific section,

wherein an interval of the gradations is same across all sections, and

wherein the length of the specific section is set as the number of gradations in the specific section multiplied by the interval of the gradations.
