What is Image Metadata

Image metadata is text information pertaining to an image file that is embedded into the file or contained in a separate file that is associated with it. Image metadata includes details relevant to the image itself as well as information about its production.

이미지 메타데이터(Image metadata)는 이미지에 대한 텍스트 형식의 데이터이다. 이 정보는 이미지 파일 안에 내장되거나 그것과 연결된 별도의 파일에 저장된다. 이미지 메타데이터는 이미지 자체와 관련된 세부 정보뿐만 아니라 이미지 생산에 관한 정보도 포함한다.

대표적인 Image Metadata 형식

• EXIF: Exchangeable image file format
• IPTC: International Press Telecommunications Council
• XMP: Extensible Metadata Platform from Adobe
