1. A method performed in an electronic apparatus to classify a reference image and an additional image from a plenoptic video during encoding the plenoptic video and then generate an atlas including a patch using the additional image, the method comprising:
mapping a depth value by performing a minimum-maximum linear scaling of the depth value in each of patches of an input image; and
finding a minimum value and a maximum value of the depth value per the patch and remapping the depth value through minimum-maximum linear scaling.
