Provided is an apparatus and method for detecting an image enhanced from a low resolution image to a high resolution image. An apparatus for detecting an image converted from a first resolution to a second resolution higher than the first resolution, the apparatus including: a frequency converter converting a received second resolution image signal to a frequency domain; and an image determiner calculating energy per frequency from the received second resolution image signal converted to the frequency domain, and if an amount of energy in over a pre-set frequency is less than a threshold, determining that 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. Accordingly, by detecting an image converted from the first resolution to the second resolution higher than the first resolution, the detected image is separately processed, thereby enhancing image quality.
