Abstract
An output method for improving video image quality is provided. First, a frame data of a first frame is received, wherein the first frame may coincide with a first type or a second type. Thereafter, the first frame is subjected to a signal process step to output a processed first frame with a first standard, wherein the processed first frame comprises a first signal to noise (S/N) ratio. Next, a frame data of a second frame with a second standard is received, wherein the second frame coincides with a third type. Thereafter, a first decompression process of frame data is performed on the second frame to output a processed second frame with the first standard, wherein the processed second frame comprises a second S/N ratio. In addition, a difference between the first S/N ratio and the second S/N ratio is smaller than a predetermined minimum tolerance.
