DICOM PS3.17 2019b - Explanatory Information

NNNN Mapping of Visible Light Photography Related Attributes to EXIF and TIFF/EP Tags (Informative)

NNNN.1 Mapping

NNNN-1 describes a mapping of EXIF Tags as defined in [EXIF 2.31] and TIFF/EP Tags as defined in [ISO 12234-2] to Visible Light Photography related Attributes. The list of EXIF and associated TIFF tags was derived from the table at http://www.exiv2.org/tags.html, updated to remove redundancies and resolve differences between EXIF 2.3 and 2.31. The intent is that this mapping support the extraction of embedded EXIF information into DICOM Attributes for accessibility in DICOM-based systems. It is not intended to define a deterministic mapping supporting round-trip full-fidelity conversion from EXIF to DICOM and back to EXIF again. Not all EXIF Tags are mapped.

When mapping EXIF values to DICOM, some tags map to multiple DICOM Attributes and vice versa, as noted. In general, Ascii types are mapped to UT VR (except that dates and times and timezone offsets are mapped to the appropriate DA, TM, DT or SH VR), Short and Long are mapped to IS VR unless they are used for a list of defined terms, in which case US VR is used, Rational and SRational are mapped to DS (VR) (i.e., each numerator and denominator pair is mapped to a single decimal representation), and Undefined is mapped to OB or UT VR as appropriate. In some special cases, the structure within a single EXIF value is expected to be decoded, e.g., the tabular representation of the OECF and Spatial Frequency Response. An appropriate choice of DICOM Specific Character Set and any corresponding character set mapping encoding conversion is expected; special handling of the decoding of character sets may be necessary for some EXIF tags, such as 37510 UserComment.

Some unmapped EXIF tags may theoretically influence the way in which an image might be displayed differently than it is encoded. E.g., Orientation (274) may contain enumerated values describing the "image orientation viewed" in terms of "visual rows and columns" related to encoded rows and columns, is not mapped. This may be a factor if the camera is physically rotated or if the user has edited the preferred orientation. In theory, such information could be mapped to a Presentation State, which is not defined by this Annex. There is no expectation that the mapping will involve re-encoding the pixel data in a different orientation, though this is not explicitly forbidden.

In NNNN-1, the word "tag" in the columns labelled "EXIF or TIFF Tag" and "EXIF or TIFF Tag description" refer to the tag in the EXIF or TIFF standards and not the DICOM Tag.

In this standard the field records both the photographer and editor copyrights, with each recorded in a separate part of the statement. When there is a clear distinction between the photographer and editor copyrights, these are to be written in the order of photographer followed by editor copyright, separated by NULL (in this case since the statement also ends with a NULL, there are two NULL codes). When only the photographer copyright is given, it is terminated by one NULL code. When only the editor copyright is given, the photographer copyright part consists of one space followed by a terminating NULL code, then the editor copyright is given. When the field is left blank, it is treated as unknown.

This tag encodes the DNG four-tier version number. For files compliant with version 1.1.0.0 of the DNG specification, this tag should contain the bytes: 1, 1, 0, 0.

0xc613

50707

Image

DNGBackward​Version

Byte

This tag specifies the oldest version of the Digital Negative specification for which a file is compatible. Readers shouldnot attempt to read a file if this tag specifies a version number that is higher than the version number of the specification the reader was based on. In addition to checking the version tags, readers should, for all tags, check the types, counts, and values, to verify it is able to correctly read the file.

0xc614

50708

Image

Unique​CameraModel

Ascii

Defines a unique, non-localized name for the camera model that created the image in the raw file. This name should include the manufacturer's name to avoid conflicts, and should not be localized, even if the camera name itself is localized for different markets (see Localized​CameraModel). This string may be used by reader software to index into per-model preferences and replacement profiles.

0xc615

50709

CFALayout

Short

Describes the spatial layout of the CFA.

0xc618

50712

Image

Linearization​Table

Short

Describes a lookup table that maps stored values into linear values. This tag is typically used to increase compression ratios by storing the raw data in a non-linear, more visually uniform space with fewer total encoding levels. If Samples​PerPixel is not equal to one, this single table applies to all the samples for each pixel.

0xc619

50713

Image

Black​LevelRepeat​Dim

Short

Specifies repeat pattern size for the Black​Level tag.

0xc61a

50714

Image

Black​Level

Rational

Specifies the zero light (a.k.a. thermal black or black current) encoding level, as a repeating pattern. The origin of this pattern is the top-left corner of the Active​Area rectangle. The values are stored in row-column-sample scan order.

0xc61b

50715

Image

Black​LevelDeltaH

SRational

If the zero light encoding level is a function of the image column, Black​LevelDeltaH specifies the difference between the zero light encoding level for each column and the baseline zero light encoding level. If Samples​PerPixel is not equal to one, this single table applies to all the samples for each pixel.

0xc61c

50716

Image

Black​LevelDeltaV

SRational

If the zero light encoding level is a function of the image row, this tag specifies the difference between the zero light encoding level for each row and the baseline zero light encoding level. If Samples​PerPixel is not equal to one, this single table applies to all the samples for each pixel.

0xc61d

50717

Image

White​Level

Short

This tag specifies the fully saturated encoding level for the raw sample values. Saturation is caused either by the sensor itself becoming highly non-linear in response, or by the camera's analog to digital converter clipping.

0xc61e

50718

Image

Default​Scale

Rational

Default​Scale is required for cameras with non-square pixels. It specifies the default scale factors for each direction to convert the image to square pixels. Typically these factors are selected to approximately preserve total pixel count. For CFA images that use CFALayout equal to 2, 3, 4, or 5, such as the Fujifilm SuperCCD, these two values should usually differ by a factor of 2.0.

0xc61f

50719

Image

Default​CropOrigin

Short

Raw images often store extra pixels around the edges of the final image. These extra pixels help prevent interpolation artifacts near the edges of the final image. Default​CropOrigin specifies the origin of the final image area, in raw image coordinates (i.e., before the Default​Scale has been applied), relative to the top-left corner of the Active​Area rectangle.

0xc620

50720

Image

Default​CropSize

Short

Raw images often store extra pixels around the edges of the final image. These extra pixels help prevent interpolation artifacts near the edges of the final image. Default​CropSize specifies the size of the final image area, in raw image coordinates (i.e., before the Default​Scale has been applied).

Color​Matrix1

SRational

Color​Matrix1 defines a transformation matrix that converts XYZ values to reference camera native color space values, under the first calibration illuminant. The matrix values are stored in row scan order. The Color​Matrix1 tag is required for all non-monochrome DNG files.

0xc622

50722

Image

Color​Matrix2

SRational

Color​Matrix2 defines a transformation matrix that converts XYZ values to reference camera native color space values, under the second calibration illuminant. The matrix values are stored in row scan order.

0xc623

50723

Image

Camera​Calibration1

SRational

Camera​Calibration1 defines a calibration matrix that transforms reference camera native space values to individual camera native space values under the first calibration illuminant. The matrix is stored in row scan order. This matrix is stored separately from the matrix specified by the Color​Matrix1 tag to allow raw converters to swap in replacement color matrices based on Unique​CameraModel tag, while still taking advantage of any per-individual camera calibration performed by the camera manufacturer.

0xc624

50724

Image

Camera​Calibration2

SRational

Camera​Calibration2 defines a calibration matrix that transforms reference camera native space values to individual camera native space values under the second calibration illuminant. The matrix is stored in row scan order. This matrix is stored separately from the matrix specified by the Color​Matrix2 tag to allow raw converters to swap in replacement color matrices based on Unique​CameraModel tag, while still taking advantage of any per-individual camera calibration performed by the camera manufacturer.

0xc625

50725

Image

Reduction​Matrix1

SRational

Reduction​Matrix1 defines a dimensionality reduction matrix for use as the first stage in converting color camera native space values to XYZ values, under the first calibration illuminant. This tag may only be used if Color​Planes is greater than 3. The matrix is stored in row scan order.

0xc626

50726

Image

Reduction​Matrix2

SRational

Reduction​Matrix2 defines a dimensionality reduction matrix for use as the first stage in converting color camera native space values to XYZ values, under the second calibration illuminant. This tag may only be used if Color​Planes is greater than 3. The matrix is stored in row scan order.

0xc627

50727

Image

Analog​Balance

Rational

Normally the stored raw values are not white balanced, since any digital white balancing will reduce the dynamic range of the final image if the user decides to later adjust the white balance; however, if camera hardware is capable of white balancing the color channels before the signal is digitized, it can improve the dynamic range of the final image. Analog​Balance defines the gain, either analog (recommended) or digital (not recommended) that has been applied the stored raw values.

0xc628

50728

Image

As​ShotNeutral

Short

Specifies the selected white balance at time of capture, encoded as the coordinates of a perfectly neutral color in linear reference space values. The inclusion of this tag precludes the inclusion of the As​ShotWhiteXY tag.

0xc629

50729

Image

As​ShotWhiteXY

Rational

Specifies the selected white balance at time of capture, encoded as x-y chromaticity coordinates. The inclusion of this tag precludes the inclusion of the As​ShotNeutral tag.

0xc62a

50730

Image

Baseline​Exposure

SRational

Camera models vary in the trade-off they make between highlight headroom and shadow noise. Some leave a significant amount of highlight headroom during a normal exposure. This allows significant negative exposure compensation to be applied during raw conversion, but also means normal exposures will contain more shadow noise. Other models leave less headroom during normal exposures. This allows for less negative exposure compensation, but results in lower shadow noise for normal exposures. Because of these differences, a raw converter needs to vary the zero point of its exposure compensation control from model to model. Baseline​Exposure specifies by how much (in EV units) to move the zero point. Positive values result in brighter default results, while negative values result in darker default results.

0xc62b

50731

Image

Baseline​Noise

Rational

Specifies the relative noise level of the camera model at a baseline ISO value of 100, compared to a reference camera model. Since noise levels tend to vary approximately with the square root of the ISO value, a raw converter can use this value, combined with the current ISO, to estimate the relative noise level of the current image.

0xc62c

50732

Image

Baseline​Sharpness

Rational

Specifies the relative amount of sharpening required for this camera model, compared to a reference camera model. Camera models vary in the strengths of their anti-aliasing filters. Cameras with weak or no filters require less sharpening than cameras with strong anti-aliasing filters.

0xc62d

50733

Image

Bayer​GreenSplit

Long

Only applies to CFA images using a Bayer pattern filter array. This tag specifies, in arbitrary units, how closely the values of the green pixels in the blue/green rows track the values of the green pixels in the red/green rows. A value of zero means the two kinds of green pixels track closely, while a non-zero value means they sometimes diverge. The useful range for this tag is from 0 (no divergence) to about 5000 (quite large divergence).

0xc62e

50734

Image

Linear​ResponseLimit

Rational

Some sensors have an unpredictable non-linearity in their response as they near the upper limit of their encoding range. This non-linearity results in color shifts in the highlight areas of the resulting image unless the raw converter compensates for this effect. Linear​ResponseLimit specifies the fraction of the encoding range above which the response may become significantly non-linear.

0xc62f

50735

Image

Camera​SerialNumber

Ascii

Camera​SerialNumber contains the serial number of the camera or camera body that captured the image.

0xc630

50736

Image

Lens​Info

Rational

Contains information about the lens that captured the image. If the minimum f-stops are unknown, they should be encoded as 0/0.

0xc631

50737

Image

Chroma​BlurRadius

Rational

Chroma​BlurRadius provides a hint to the DNG reader about how much chroma blur should be applied to the image. If this tag is omitted, the reader will use its default amount of chroma blurring. Normally this tag is only included for non-CFA images, since the amount of chroma blur required for mosaic images is highly dependent on the de-mosaic algorithm, in which case the DNG reader's default value is likely optimized for its particular de-mosaic algorithm.

0xc632

50738

Image

Anti​AliasStrength

Rational

Provides a hint to the DNG reader about how strong the camera's anti-alias filter is. A value of 0.0 means no anti-alias filter (i.e., the camera is prone to aliasing artifacts with some subjects), while a value of 1.0 means a strong anti-alias filter (i.e., the camera almost never has aliasing artifacts).

0xc633

Shadow​Scale

SRational

This tag is used by Adobe Camera Raw to control the sensitivity of its 'Shadows' slider.

0xc634

Maker​NoteSafety

Short

Maker​NoteSafety lets the DNG reader know whether the EXIF Maker​Note tag is safe to preserve along with the rest of the EXIF data. File browsers and other image management software processing an image with a preserved Maker​Note should be aware that any thumbnail image embedded in the Maker​Note may be stale, and may not reflect the current state of the full size image.

0xc65a

50778

0xc65b

50779

Image

Calibration​Illuminant2

Short

The illuminant used for an optional second set of color calibration tags (Color​Matrix2, Camera​Calibration2, Reduction​Matrix2). The legal values for this tag are the same as the legal values for the Calibration​Illuminant1 tag; however, if both are included, neither is allowed to have a value of 0 (unknown).

0xc65c

50780

Image

Best​QualityScale

Rational

For some cameras, the best possible image quality is not achieved by preserving the total pixel count during conversion. For example, Fujifilm SuperCCD images have maximum detail when their total pixel count is doubled. This tag specifies the amount by which the values of the Default​Scale tag need to be multiplied to achieve the best quality image size.

0xc65d

50781

Image

Raw​DataUniqueID

Byte

This tag contains a 16-byte unique identifier for the raw image data in the DNG file. DNG readers can use this tag to recognize a particular raw image, even if the file's name or the metadata contained in the file has been changed. If a DNG writer creates such an identifier, it should do so using an algorithm that will ensure that it is very unlikely two different images will end up having the same identifier.

Image

Original​RawFile​Data

Undefined

If the DNG file was converted from a non-DNG raw file, then this tag contains the compressed contents of that original raw file. The contents of this tag always use the big-endian byte order. The tag contains a sequence of data blocks. Future versions of the DNG specification may define additional data blocks, so DNG readers should ignore extra bytes when parsing this tag. DNG readers should also detect the case where data blocks are missing from the end of the sequence, and should assume a default value for all the missing blocks. There are no padding or alignment bytes between data blocks.

0xc68d

50829

Active​Area

Short

This rectangle defines the active (non-masked) pixels of the sensor. The order of the rectangle coordinates is: top, left, bottom, right.

0xc68e

50830

Image

Masked​Areas

Short

This tag contains a list of non-overlapping rectangle coordinates of fully masked pixels, which can be optionally used by DNG readers to measure the black encoding level. The order of each rectangle's coordinates is: top, left, bottom, right. If the raw image data has already had its black encoding level subtracted, then this tag should not be used, since the masked pixels are no longer useful.

0xc68f

50831

Image

As​ShotICCProfile

Undefined

This tag contains an ICC profile that, in conjunction with the As​ShotPre​ProfileMatrix tag, provides the camera manufacturer with a way to specify a default color rendering from camera color space coordinates (linear reference values) into the ICC profile connection space. The ICC profile connection space is an output referred colorimetric space, whereas the other color calibration tags in DNG specify a conversion into a scene referred colorimetric space. This means that the rendering in this profile should include any desired tone and gamut mapping needed to convert between scene referred values and output referred values.

0xc690

50832

Image

As​ShotPre​ProfileMatrix

SRational

This tag is used in conjunction with the As​ShotICCProfile tag. It specifies a matrix that should be applied to the camera color space coordinates before processing the values through the ICC profile specified in the As​ShotICCProfile tag. The matrix is stored in the row scan order. If Color​Planes is greater than three, then this matrix can (but is not required to) reduce the dimensionality of the color data down to three components, in which case the As​ShotICCProfile should have three rather than Color​Planes input components.

0xc691

50833

Image

CurrentICCProfile

Undefined

This tag is used in conjunction with the Current​PreProfile​Matrix tag. The CurrentICCProfile and Current​PreProfile​Matrix tags have the same purpose and usage as the As​ShotICCProfile and As​ShotPre​ProfileMatrix tag pair, except they are for use by raw file editors rather than camera manufacturers.

Colorimetric​Reference

Short

The DNG color model documents a transform between camera colors and CIE XYZ values. This tag describes the colorimetric reference for the CIE XYZ values. 0 = The XYZ values are scene-referred. 1 = The XYZ values are output-referred, using the ICC profile perceptual dynamic range. This tag allows output-referred data to be stored in DNG files and still processed correctly by DNG readers.

0xc6f7

50935

Image

Noise​ReductionApplied

Rational

This tag indicates how much noise reduction has been applied to the raw data on a scale of 0.0 to 1.0. A 0.0 value indicates that no noise reduction has been applied. A 1.0 value indicates that the "ideal" amount of noise reduction has been applied, i.e. that the DNG reader should not apply additional noise reduction by default. A value of 0/0 indicates that this parameter is unknown.

0xc6f8

50936

Image

Profile​Name

Byte

A UTF-8 encoded string containing the name of the camera profile. This tag is optional if there is only a single camera profile stored in the file but is required for all camera profiles if there is more than one camera profile stored in the file.

Profile​HueSat​MapDims

Long

This tag specifies the number of input samples in each dimension of the hue/saturation/value mapping tables. The data for these tables are stored in Profile​HueSat​MapData1 and Profile​HueSat​MapData2 tags. The most common case has Value​Divisions equal to 1, so only hue and saturation are used as inputs to the mapping table.

Profile​ToneCurve

Float

This tag contains a default tone curve that can be applied while processing the image as a starting point for user adjustments. The curve is specified as a list of 32-bit IEEE floating-point value pairs in linear gamma. Each sample has an input value in the range of 0.0 to 1.0, and an output value in the range of 0.0 to 1.0. The first sample is required to be (0.0, 0.0), and the last sample is required to be (1.0, 1.0). Interpolated the curve using a cubic spline.

Float

This tag contains a default "look" table that can be applied while processing the image as a starting point for user adjustment. This table uses the same format as the tables stored in the Profile​HueSat​MapData1 and Profile​HueSat​MapData2 tags, and is applied in the same color space. However, it should be applied later in the processing pipe, after any exposure compensation and/or fill light stages, but before any tone curve stage. Each entry of the table contains three 32-bit IEEE floating-point values. The first entry is hue shift in degrees, the second entry is a saturation scale factor, and the third entry is a value scale factor. The table entries are stored in the tag in nested loop order, with the value divisions in the outer loop, the hue divisions in the middle loop, and the saturation divisions in the inner loop.
