Electronic apparatus and controlling method thereof

An electronic apparatus, comprising:

• a display;
• a memory configured to store at least one instruction;
• and
• a processor, configured to execute the at least one instruction, to:
• control the display to display image content,
• acquire information on an average picture level (APL) value representing average brightness of pixels of image frames included in the image content,
• identify based on the information on the APL value, whether a first scene including first image frames, among the image frames, having a first APL value that is less than a preset threshold value transitions to a second scene including second image frames, among the image frames, while the image content is displayed on the display, the second image frames having a second APL value that is greater than or equal to the preset threshold value,
• adjust, based on the first scene being identified as transitioning to the second scene, a current scaling ratio for the second scene while the second scene is displayed on the display, the current scaling ratio being adjusted such that the second scene increases from a second current scaling ratio that is lower than a first current scaling ratio corresponding to the second APL value to the first current scaling ratio, and
• control the display to display the second image frames included in the second scene based on the adjusted current scaling ratio for the second scene.
