Abstract

Provided is an apparatus and method for detecting an image enhanced from a low resolution image to a high resolution image. An apparatus detects an image converted from a first resolution to a higher second resolution. A frequency converter converts a received second resolution image signal to a frequency domain. An image determiner calculates energy per frequency from the received second resolution image signal. If an amount of energy in over a pre-set frequency is less than a threshold, the received second resolution image signal corresponds to a second resolution image converted from a first resolution image, and if the amount of energy in over the pre-set frequency is greater than the threshold, determining that the received second resolution image signal corresponds to a real second resolution image.
