Inquiring system for high-resolution image materials

摘要

The National Police Agency of Japan (NPA) developed an inquiring system for high-resolution image materials (ISI) that can handle image information. The author explains the structure and capacity of this system and the effect that can be expected when it is fully implemented. Image information, such as photographs of suspects and the scenes of crimes, is filed and utilized at respective prefectural police headquarters (PPHs). The ISI will enable the NPA to control entry and management of such image information as well as other relevant information with its high speed data network, computers, and optical disk equipment so that every PPH will be able to make quick inquiries using nationwide photo data. Implementation of the ISI had been completed in 26 PPHs at the end of March 1992 and will completed in all PHHs by the end of March 1994.
