The method for determining a frame rate in an electronic device, according to one embodiment, comprises the steps of: comparing 1st display data to be displayed at a reference time and 2nd display data to be displayed after the reference time; and determining a frame rate based on the comparison result. The method for determining a frame rate in an electronic device can be implemented through various embodiments. ## Claims ### Claim 1 A method for determining a frame rate in an electronic device, the method comprising: displaying, based on a frame rate, a first screen corresponding to a first image; identifying whether a number of pixels that change in a first reference area of the first image and a second image is greater than a threshold, the second image being subsequent to the first image; when the number of pixels is greater than or equal to the threshold, displaying, based on another frame rate that is different from the frame rate, a second screen corresponding to the second image; and when the number of pixels is not greater than or equal to the threshold, maintaining the frame rate and displaying, based on the maintained frame rate, the second screen. ### Claim 2 (depends on 1) The method of claim 1, wherein the changing of the frame rate further comprises: when the number of pixels is greater than or equal to the threshold, changing the frame rate to another frame rate higher than the frame rate. ### Claim 3 (depends on 1) The method of claim 1, further comprising: identifying whether a number of pixels that change in a second reference area of the first image and the second image is greater than or equal to the threshold; and when the number of pixels in the second reference area is greater than or equal to the threshold, changing a frame rate for each area to another frame rate different from the frame rate. ### Claim 4 An electronic device comprising: a display; a memory; and a processor configured to: control the display to display, based on a frame rate, a first screen corresponding to a first image stored in the memory, identify whether a number of pixels that change in a first reference area of the first image and a second image is greater than a threshold, the second image being subsequent to the first image and stored in the memory, when the number of pixels is greater than or equal to the threshold, control the display to display, based on another frame rate that is different from the frame rate, a second screen corresponding to the second image, and when the number of pixels is not greater than or equal to the threshold, control the display to maintain the frame rate and display, based on the maintained frame rate, the second screen. ### Claim 5 (depends on 4) The electronic device of claim 4, wherein the processor is further configured to: when the number of pixels is greater than or equal to the threshold, change the frame rate to another frame rate higher than the frame rate. ### Claim 6 (depends on 4) The electronic device of claim 4, wherein the processor is further configured to: identify whether a number of pixels that change in a second reference area of the first image and the second image is greater than or equal to the threshold; and when the number of pixels in the second reference area is greater than or equal to the threshold, change a frame rate for each area to another frame rate different from the frame rate. ### Claim 7 (depends on 6) The method of claim 6, wherein the first reference area and the second reference area are tiles in a grid that encompasses an entire area of the display.
