IMAGE PROCESSING METHOD AND IMAGE PROCESSING DEVICE

摘要

An image decoder (10) decodes a code sequence (CS) and generates an original image signal (SHR) with a 1st resolution and, further, extracts encoding parameters (PAR) such as a motion vector and an orthogonal transformation type from the code sequence (CS). A resolution converter (20) judges the characteristics of the original image signal (SHR) in accordance with the encoding parameters (PAR) and converts the original image signal (SHR) into a new image signal (SLR) with a 2nd resolution by a resolution conversion method corresponding to the characteristics.
