Photometric Interpretation Attribute

Tag(0028,0004)
TypeRequired (1)
KeywordPhotometricInterpretation
Value Multiplicity1
Value RepresentationCode String (CS)

Specifies the intended interpretation of the pixel data. See Section C.7.6.3.1.2 for further explanation.

Section C.7.6.3.1.2

C.7.6.3.1.2 Photometric Interpretation

The value of Photometric Interpretation (0028,0004) specifies the intended interpretation of the image pixel data.

See PS3.5 for restrictions imposed by compressed Transfer Syntaxes.

The following values are defined. Other values are permitted but the meaning is not defined by this Standard.

Defined Terms:

MONOCHROME1

Pixel data represent a single monochrome image plane. The minimum sample value is intended to be displayed as white after any VOI gray scale transformations have been performed. See PS3.4. This value may be used only when Samples per Pixel (0028,0002) has a value of 1.

MONOCHROME2

Pixel data represent a single monochrome image plane. The minimum sample value is intended to be displayed as black after any VOI gray scale transformations have been performed. See PS3.4. This value may be used only when Samples per Pixel (0028,0002) has a value of 1.

PALETTE COLOR

Pixel data describe a color image with a single sample per pixel (single image plane). The pixel value is used as an index into each of the Red, Blue, and Green Palette Color Lookup Tables (0028,1101-1103&1201-1203). This value may be used only when Samples per Pixel (0028,0002) has a value of 1. When the Photometric Interpretation is Palette Color; Red, Blue, and Green Palette Color Lookup Tables shall be present.

RGB

Pixel data represent a color image described by red, green, and blue image planes. The minimum sample value for each color plane represents minimum intensity of the color. This value may be used only when Samples per Pixel (0028,0002) has a value of 3.

HSV

Retired.

ARGB

Retired.

CMYK

Retired.

YBR_FULL

Pixel data represent a color image described by one luminance (Y) and two chrominance planes (CB and CR). This photometric interpretation may be used only when Samples per Pixel (0028,0002) has a value of 3. Black is represented by Y equal to zero. The absence of color is represented by both CB and CR values equal to half full scale.

Note

In the case where Bits Allocated (0028,0100) has value of 8 half full scale is 128.

In the case where Bits Allocated (0028,0100) has a value of 8 then the following equations convert between RGB and YCBCR Photometric Interpretation.

Y = + .2990R + .5870G + .1140B

CB= - .1687R - .3313G + .5000B + 128

CR= + .5000R - .4187G - .0813B + 128

Note

The above is based on CCIR Recommendation 601-2 dated 1990.

YBR_FULL_422

The same as YBR_FULL except that the CB and CR values are sampled horizontally at half the Y rate and as a result there are half as many CB and CR values as Y values.

This Photometric Interpretation is only allowed with Planar Configuration (0028,0006) equal to 0. Two Y values shall be stored followed by one CB and one CR value. The CB and CR values shall be sampled at the location of the first of the two Y values. For each Row of Pixels, the first CB and CR samples shall be at the location of the first Y sample. The next CB and CR samples shall be at the location of the third Y sample etc.

Note

This subsampling is often referred to as cosited sampling.

YBR_PARTIAL_422

The same as YBR_FULL_422 except that:

  1. black corresponds to Y = 16;

  2. Y is restricted to 220 levels (i.e., the maximum value is 235);

  3. CB and CR each has a minimum value of 16;

  4. CB and CR are restricted to 225 levels (i.e., the maximum value is 240);

  5. lack of color is represented by CB and CR equal to 128.

In the case where Bits Allocated (0028,0100) has value of 8 then the following equations convert between RGB and YBR_PARTIAL_422 Photometric Interpretation

Y = + .2568R + .5041G + .0979B + 16

CB= - .1482R - .2910G + .4392B + 128

CR= + .4392R - .3678G - .0714B + 128

Note

The above is based on CCIR Recommendation 601-2 dated 1990.

YBR_PARTIAL_420

The same as YBR_PARTIAL_422 except that the CB and CR values are sampled horizontally and vertically at half the Y rate and as a result there are four times less CB and CR values than Y values, versus twice less for YBR_PARTIAL_422.

This Photometric Interpretation is only allowed with Planar Configuration (0028,0006) equal to 0. The CB and CR values shall be sampled at the location of the first of the two Y values. For the first Row of Pixels (etc.), the first CB and CR samples shall be at the location of the first Y sample. The next CB and CR samples shall be at the location of the third Y sample etc. The next Rows of Pixels containing CB and CR samples (at the same locations than for the first Row) will be the third etc.

YBR_ICT

Irreversible Color Transformation:

Pixel data represent a color image described by one luminance (Y) and two chrominance planes (CB and CR). This photometric interpretation may be used only when Samples per Pixel (0028,0002) has a value of 3. Black is represented by Y equal to zero. The absence of color is represented by both CB and CR values equal to zero.

Regardless of the value of Bits Allocated (0028,0100), the following equations convert between RGB and YCBCR Photometric Interpretation.

Y = + .29900R + .58700G + .11400B

CB= - .16875R - .33126G + .50000B

CR= + .50000R - .41869G - .08131B

Note

  1. The above is based on [ISO/IEC 15444-1] (JPEG 2000).

  2. In a JPEG 2000 bit stream, DC level shifting (used if the untransformed components are unsigned) is applied before forward color transformation, and the transformed components may be signed (unlike in JPEG ISO/IEC 10918-1).

  3. In JPEG 2000, spatial down-sampling of the chrominance components, if performed, is signaled in the JPEG 2000 bit stream.

YBR_RCT

Reversible Color Transformation:

Pixel data represent a color image described by one luminance (Y) and two chrominance planes (CB and CR). This photometric interpretation may be used only when Samples per Pixel (0028,0002) has a value of 3. Black is represented by Y equal to zero. The absence of color is represented by both CB and CR values equal to zero.

Regardless of the value of Bits Allocated (0028,0100), the following equations convert between RGB and YBR_RCT Photometric Interpretation.

Y = ⌊(R + 2G +B) / 4⌋ (Note: ⌊…⌋ mean floor)

CB= B - G

CR= R - G

The following equations convert between YBR_RCT and RGB Photometric Interpretation.

G = Y - ⌊ (CR+ CB) / 4⌋

R = CR+ G

B = CB+ G

Note

  1. The above is based on [ISO/IEC 15444-1] (JPEG 2000).

  2. In a JPEG 2000 bit stream, DC level shifting (used if the untransformed components are unsigned) is applied before forward color transformation, and the transformed components may be signed (unlike in JPEG ISO/IEC 10918-1).

  3. This photometric interpretation is a reversible approximation to the YUV transformation used in PAL and SECAM.
