Patent number: 10192294Abstract: An image processing apparatus and an image processing method which can transmit/receive or display a high-dynamic-range image suitably are provided. An image transmission apparatus transfers, as metadata of content, luminance conversion information, which is for conversion of HDR content (for example, with maximum luminance 2000 nit) into SDR content (having, for example, 100 nit), or differential information. Based on the metadata, an image reception apparatus generates luminance conversion information, in which received HDR content is adapted to a capability of a display (for example, with maximum luminance 500 nit or 1000 nit) in an output destination, and realizes display mapping which is not against an intention of a producer.Type: GrantFiled: July 21, 2015Date of Patent: January 29, 2019Assignee: Sony CorporationInventors: Takumi Tsuru, Hiroaki Eto, Toshiya Hamada, Kenichi Kanai, Tomizo Shiraishi
