wherein, when the color space of the main content image corresponds to BT.2020 format, the circuitry determines to not convert the color space of the sub-content image into BT.2020 format, and
wherein, when a dynamic range of the main content image corresponds to high dynamic range (HDR) having expanded color and luminance ranges as compared to standard dynamic range (SDR), the circuitry determines to not convert a dynamic range of the sub-content image into HDR.
2. The information processing apparatus according to claim 1 , wherein the same color space corresponds to BT.709 format.
3. The information processing apparatus according to claim 1 , wherein the circuitry is further configured to apply no color space conversion to the color space of the sub-content image, when the color space of the main content image corresponds to BT.2020 format.
4. An information processing apparatus that reproduces data recorded onto a recording medium, the apparatus comprising:
circuitry configured to
convert a color space of an image recorded onto the recording medium,
convert a dynamic range of the image recorded onto the recording medium, and
superimpose a main content image and a sub-content image recorded onto the recording medium,
wherein, when a color space of the main content image corresponds to BT.709 format, the circuitry determines to convert color spaces of the sub-content image and the main content image into a same color space,
wherein, when the color space of the main content image corresponds to BT.2020 format, no color space conversion is applied to the color space of the sub-content image, and
wherein, when a dynamic range of the main content image corresponds to high dynamic range (HDR) having expanded color and luminance ranges as compared to standard dynamic range (SDR), no conversion is applied to a dynamic range of the sub-content image.
