Super Resolution (SR) has recently become a household phrase in Japan. Commercial products such as TV sets, BluRay players and digital cameras are equipped with SR function and are sold in the market. Although there are several types of SR technologies for commercial products and their details are not open, some of them are not even new technologies and are just modified conventional ones. However, according to official web pages of certain manufacturers of them they are being marketed to the public as all new technologies. One of the new SR technologies for them is the super resolution image reconstruction (SRR). Most of SR technologies have complex algorithms such as iterations under constraint conditions and precise motion vector detections. Although SRR also has a complex algorithm, it is the only SR technology for real time equipment. However, in principle there is a limit of resolution improvement with SRR even if it works perfectly. In this paper the limitation of SRR is discussed.
