VkSamplerYcbcrModelConversion - Color model component of a color space

Description

• SAMPLER_YCBCR_MODEL_CONVERSION_RGB_IDENTITY specifies that the input values to the conversion are unmodified.

• SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_IDENTITY specifies no model conversion but the inputs are range expanded as for Y′CBCR.
• SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_709 specifies the color model conversion from Y′CBCR to R′G′B′ defined in BT.709 and described in the “BT.709 Y’CBCR conversion” section of the Khronos Data Format Specification.
• SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_601 specifies the color model conversion from Y′CBCR to R′G′B′ defined in BT.601 and described in the “BT.601 Y’CBCR conversion” section of the Khronos Data Format Specification.
• SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_2020 specifies the color model conversion from Y′CBCR to R′G′B′ defined in BT.2020 and described in the “BT.2020 Y’CBCR conversion” section of the Khronos Data Format Specification.

In the VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_* color models, for the input to the sampler Y′CBCR range expansion and model conversion:

• the Y (Y′ luma) channel corresponds to the G channel of an RGB image.
• the CB (CB or “U” blue color difference) channel corresponds to the B channel of an RGB image.
• the CR (CR or “V” red color difference) channel corresponds to the R channel of an RGB image.
• the alpha channel, if present, is not modified by color model conversion.

These rules reflect the mapping of channels after the channel swizzle operation (controlled by SamplerYcbcrConversionCreateInfo::components).

Note

For example, an “YUVA” 32-bit format comprising four 8-bit channels can be implemented as FORMAT_R8G8B8A8_UNORM with a component mapping:

• components.a = COMPONENT_SWIZZLE_IDENTITY
• components.r = COMPONENT_SWIZZLE_B
• components.g = COMPONENT_SWIZZLE_R
• components.b = COMPONENT_SWIZZLE_G
