Disclosed are a method for measuring a color space interference distortion and a device thereof. The disclosed device and method can measure how much distortion in color components occurring in a process of down-sampling the color components is applied to brightness components. Moreover, the disclosed device and method can measure how the distortion in the color components occurring in the process of down-sampling the color components is cognitively affected. To this end, the method comprises the steps of: calculating a first value which is interference distortion between a first region and a third region; calculating a second value which is interference distortion between a second region and the third region; and measuring the interference distortion due to down-sampling of the color components using the first value and the second value.
