Abstract
An image processing apparatus and an image processing method to preferably transmit/receive or display high dynamic range images. In an image transmission system implementation, metadata is transmitted, the metadata storing information such as peak luminance, color gamut and optical-electro transfer or other characteristics of high dynamic range (HDR) content. An image receiving apparatus utilizes the metadata to perform dynamic range conversion using the metadata to adapt its display to display the HDR content.
