Transmission apparatus, method of transmitting image data in high dynamic range, reception apparatus, method of receiving image data in high dynamic range, and program

摘要

A transmission apparatus (synchronized apparatus) transmits HDR image data to a reception apparatus (source apparatus) over a transmission path. At that time, the transmission apparatus transmits information on a transmission method for and/or information on gamma correction for the HDR image data to the reception apparatus over the transmission path. The reception apparatus performs processing (decoding processing, gamma correction processing, and the like) on the received HDR image data, based on the information on the transmission method and/or the information on the gamma correction that are received. For example, the transmission apparatus receives from the reception apparatus the pieces of information on the transmission method and/or the gamma correction that the reception apparatus can support, selects the method that the reception apparatus can support, and thus uses the selected method.

主权项

1. A transmission apparatus comprising:
a data transmission unit that transmits image data in a high dynamic range to an external apparatus over a transmission path; and an information transmission unit that transmits information on a transmission method for and/or information on gamma correction for the image data in the high dynamic range that is transmitted in the data transmission unit, to the external apparatus over the transmission path.
