Abstract
An electronic apparatus is disclosed. The electronic apparatus includes: a memory storing a first pattern image and a second pattern image, a communication interface comprising communication circuitry configured to communicate with an external terminal apparatus, a projection part including a projection lens, and a processor configured to: control the projection part to project the first pattern image on a screen member comprising a reflector located on a projection surface, and based on receiving a first photographed image which photographed the screen member from the external terminal apparatus through the communication interface, acquire transformation information based on the first photographed image and the first pattern image, control the projection part to project the second pattern image on the projection surface, and based on receiving a second photographed image which photographed the projection surface from the external terminal apparatus through the communication interface, perform color calibration based on the characteristic of the projection surface based on the second photographed image, the second pattern image, and the transformation information.
