Abstract: PURPOSE: A device and a method for estimating an image quality are provided to accurately evaluate image quality. CONSTITUTION: A bit string parameter extracting unit(200) comprises a motion degree predicting unit, a quantization parameter extracting unit, and a transmission error predicting unit. The bit string parameter extracting unit extracts parameter from transmitted and encoded bit string. A DMOS(Difference Mean Opinion Score) prediction unit(300) calculates DMOS value by using the parameter extracted from the bit string parameter extracting unit. The patemeter extracted from the bit string parameter extracting unit comprises a motion rate value, a quantization parameter, and transmission error value.
