Abstract

The present invention relates to an image encoding and decoding technique for a high-definition video compression method and device for an omnidirectional security camera, and more specifically, to amethod and a device whereby a differential motion vector is effectively transmitted, and an actual motion vector is calculated using the transmitted differential motion vector, and thus motion compensation is performed.

Description

technical field [0001] The present invention relates to image encoding and decoding techniques in high-quality video compression methods and devices for omnidirectional security cameras. And more particularly, the present invention relates to a method and apparatus for efficiently transmitting differential motion vectors, calculating actual motion vectors from the transmitted differential motion vectors, and thus performing motion compensation. Background technique [0002] In recent years, there has been a growing demand for various devices and systems for security due to the increase in social anxiety caused by crimes such as indiscriminate crimes against non-specific groups, retaliatory crimes against specific targets, and crimes against the socially vulnerable Increase. In particular, security cameras (CCTV) can be used as evidence on crime scenes or impression descriptions of criminals, so the demand for personal security as well as national demand is increasing. Howe...
