Abstract: Disclosed are a method of upsampling based on a maximum-resolution image and red, green and blue (RGB) composition and an apparatus performing the same. An image generating method may include acquiring visible-channel images included in multi-spectrum images, upsampling a remaining image excluding a maximum-resolution image from the visible-channel images, based on the maximum-resolution image among the visible-channel images, and generating an RGB composite image by composing the upsampled remaining image and the maximum-resolution image.
