Abstract

To display images by suitably superimposing a graphics image on a high-dynamic-range image in an easily visible manner. GOEA dynamic range converter ( 311 ) converts a SDR graphics image to an HDR graphics image based on metadata. An image combiner ( 312 ) combines the graphics image of which the dynamic range has been converted to HDR with HDR content. A dynamic range converter ( 313 ) performs display mapping on the HDR content combined with the graphics image based on metadata.

First claim

1 . An image processing apparatus comprising:
a metadata acquiring unit that acquires metadata of image data; and a processor that processes a graphics image to be superimposed on the image data based on the metadata.
