Electronic apparatus and control method thereof

An electronic apparatus comprising:

• a processor configured to:
• obtain an image captured by a camera;
• obtain a downscaled image by downscaling the captured image, wherein the downscaled image is an image that is less than a critical resolution;
• identify a region of interest included in the downscaled image by inputting the downscaled image comprising a preceding image and a subsequent image in a time order into a first artificial intelligence model, the first artificial intelligence model being trained to identify a region of interest in an input image by comparing a preceding image comprised in the input image with a subsequent image comprised in the input image;
• extract, from the captured image greater than or equal to the critical resolution, an object image in the captured image corresponding to the identified region of interest, wherein the object image is an image that is greater than or equal to a critical size;
• and
• obtain information on an object region included in the captured image by inputting the extracted object image into a second artificial intelligence model, the second artificial intelligence model being configured to identify an object region in an input image.
