Cooking appliance that provides time-lapse video and controlling method thereof

A controlling method of a cooking appliance, the controlling method comprising:

• based on cooking being started, obtaining a reference image of an inside of a cooking chamber captured by a camera;
• obtaining a plurality of images of the inside of the cooking chamber at a preset time interval while an inner chamber of the cooking chamber rotates in a first direction;
• storing the plurality of images by matching the plurality of images with a rotation angle of the inner chamber at a time the plurality of images are captured;
• obtain a plurality of rotated images by rotating the plurality of images in a second direction by a rotation angle stored that matches the plurality of images, the second direction being opposite to the first direction;
• obtaining a plurality of cropped images by cropping the plurality of rotated images such that the plurality of rotated images correspond to the reference image;
• and
• providing a time-lapse video using the reference image and the plurality of cropped images

A non-transitory computer-readable recording medium including a program that executable to perform a controlling method of a cooking appliance, the controlling method comprises:

• based on cooking being started, obtaining a reference image of an inside of a cooking chamber captured by a camera;
• obtaining a plurality of images of the inside of the cooking chamber at a preset time interval while an inner chamber of the cooking chamber rotates in a first direction;
• storing the plurality of images by matching each of the plurality of images with a rotation angle of the inner chamber at a time when the plurality of images are captured, respectively;
• obtain a plurality of rotated images by rotating the plurality of images in a second direction by a rotation angle stored that matches the plurality of images, the second direction being opposite to the first direction;
• obtaining a plurality of cropped images by cropping the plurality of rotated images such that the plurality of rotated images correspond to the reference image;
• and
• providing a time-lapse video using the reference image and the plurality of cropped images.
