摘要： Signals are provided which allow colors in a wider color range than predetermined standards, which can be handled by apparatus according to such predetermined standards. A primary color converter converts first color signals having primary color points in a wider color range than the primary color points according to BT.709 into second color signals based on the primary colors according to BT.709. A photoelectric transducer converts the second color signals into third color signals according to photoelectric transducer characteristics defined in a numerical range wider than a range from 0 to 1.0 of color signals corresponding to a luminance signal and color difference signals according to BT.709. A color signal converter converts the third color signals into a luminance signal and color difference signals. A corrector incorporated in the color signal converter corrects the color difference signals into color difference signals.

摘要： 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.
