EXIF
| Vlastnost | Česky | Formát | Popis |
| ImageDescription | string | Describes the image. | |
| Make | string | The manufacturer of the recording
equipment. This is the manufacturer of the DSC, scanner,
video digitizer or other equipment that generated the image. |
|
| Model | string | Shows model number of digicam | |
| Orientation | integer | The orientation of the camera relative
to the scene, when the image was captured 1 top left side 2 top right side 3 bottom right side 4 bottom left side 5 left side top 6 right side top 7 right side bottom 8 left side bottom |
|
| XResolution | double | Resolution of image. Default value is 1/72 inch (one 'point'), but it has no meaning because personal computers typicaly don't use this value to display/print. | |
| YResolution | double | Resolution of image. Default value is 1/72 inch (one 'point'), but it has no meaning because personal computers typicaly don't use this value to display/print. | |
| Software | string | Shows firmware(internal software of digicam) version number | |
| DateTime | string | Date/Time of image was last modified. Data format is "YYYY:MM:DD HH:MM:SS"+0x00, total 20 bytes. If clock has not set or digicam doesn't have clock, the field may be filled with spaces. Usually it has the same value of DateTimeOriginal. | |
| Copyright | string | Shows copyright information. | |
| ExposureTime | double | Exposure time (reciprocal of shutter speed). Unit is second. | |
| FNumber | double | The actual F-number (F-stop) of lens when the image was taken. | |
| ExposureProgram | integer | Exposure program that the camera used when image was taken. 1 means manual control 2 program normal 3 aperture priority 4 shutter priority 5 program creative (slow program) 6 program action (high-speed program) 7 portrait mode 8 landscape mode. |
|
| ExifVersion | string | Exif version number. Stored as 4 bytes of ASCII characters. If the picture is based on Exif V2.1, value is "0210". Since the type is 'undefined', there is no NULL (0x00) for termination. | |
| DateTimeOriginal | string | Date/Time that the original image was taken. This value should not be modified by user program. Data format is "YYYY:MM:DD HH:MM:SS"+0x00, total 20bytes. If clock has not set or digicam doesn't have clock, the field may be filled with spaces. In the Exif standard, this tag is optional, but it is mandatory for DCF. | |
| DateTimeDigitized | string | Date/Time of image digitized. Usually, it contains the same value of DateTimeOriginal (0x9003). Data format is "YYYY:MM:DD HH:MM:SS"+0x00, total 20 bytes. If clock has not set or digicam doesn't have clock, the field may be filled with spaces. In the Exif standard, this tag is optional, but it is mandatory for DCF. | |
| CompressedBitsPerPixel | double | The average compression ratio of JPEG (rough estimate) | |
| ShutterSpeedValue | double | Shutter speed by APEX value. To convert this value to ordinary 'Shutter Speed'; calculate this value's power of 2, then reciprocal. For example, if the ShutterSpeedValue is '4', shutter speed is 1/(24)=1/16 second. | |
| ApertureValue | double | The actual aperture value of the lens when the image was taken. Unit is APEX. To convert this value to ordinary F-number (F-stop), calculate this value's power of root 2 (=1.4142). For example, if the ApertureValue is '5', F-number is 1.41425 = F5.6. | |
| BrightnessValue | double | Brightness of taken subject, unit is APEX. To calculate Exposure (Ev) from BrigtnessValue (Bv), you must add SensitivityValue(Sv). Ev=Bv+Sv Sv=log2(ISOSpeedRating/3.125) ISO100:Sv=5, ISO200:Sv=6, ISO400:Sv=7, ISO125:Sv=5.32. |
|
| ExposureBiasValue | double | Exposure bias (compensation) value of taking picture. Unit is APEX (EV). | |
| MaxApertureValue | double | Maximum aperture value of the lens. Convert to F-number by calculating power of root 2 (same process as ApertureValue). | |
| SubjectDistance | double | Distance to focus point, unit is meters. | |
| MeteringMode | integer | Exposure metering method: 0 means unknown 1 average 2 center weighted average 3 spot 4 multi-spot 5 multi-segment 6 partial 255 other |
|
| LightSource | integer | Light source, actually this means white
balance setting: 0 means unknown 1 daylight 2 fluorescent 3 tungsten 10 flash 17 standard light A 18 standard light B 19 standard light C 20 D55 21 D65 22 D75 255 other |
|
| Flash | integer | 0 means flash did not fire 1 flash fired 5 flash fired but strobe return light not detected 7 flash fired and strobe return light detected |
|
| FocalLength | double | Focal length of lens used to take image. Unit is millimeters. | |
| SubsecTime | string | Some of digicam can take 2~30 pictures per second, but DateTime/DateTimeOriginal/DateTimeDigitized tag can't record the sub-second time. SubsecTime tag is used to record it. For example, DateTimeOriginal = "1996:09:01 09:15:30", SubSecTimeOriginal = "130", Combined original time is "1996:09:01 09:15:30.130" |
|
| SubsecTimeOriginal | string | Some of digicam can take 2~30 pictures per second, but DateTime/DateTimeOriginal/DateTimeDigitized tag can't record the sub-second time. SubsecTime tag is used to record it. For example, DateTimeOriginal = "1996:09:01 09:15:30", SubSecTimeOriginal = "130", Combined original time is "1996:09:01 09:15:30.130" |
|
| SubsecTimeDigitized | string | Some of digicam can take 2~30 pictures per second, but DateTime/DateTimeOriginal/DateTimeDigitized tag can't record the sub-second time. SubsecTime tag is used to record it. For example, DateTimeOriginal = "1996:09:01 09:15:30", SubSecTimeOriginal = "130", Combined original time is "1996:09:01 09:15:30.130" |
|
| FlashPixVersion | string | Stores FlashPix version. If the image data is based on FlashPix format Ver.1.0, value is "0100". | |
| ColorSpace | string | Defines Color Space. DCF image must use sRGB color space so value is always '1'. If the picture uses the other color space, value is '65535':Uncalibrated. | |
| ExifImageWidth | integer | Size of main image. | |
| ExifImageHeight | integer | Size of main image. | |
| RelatedSoundFile | string | If this digicam can record audio data with image, shows name of audio data. | |
| FocalPlaneXResolution | double | Pixel density at CCD's position. If you have MegaPixel digicam and take a picture by lower resolution (e.g.VGA mode), this value is re-sampled by picture resolution. In such case, FocalPlaneResolution is not same as CCD's actual resolution. | |
| FocalPlaneYResolution | double | Pixel density at CCD's position. If you have MegaPixel digicam and take a picture by lower resolution (e.g.VGA mode), this value is re-sampled by picture resolution. In such case, FocalPlaneResolution is not same as CCD's actual resolution. | |
| FocalPlaneResolutionUnit | integer | Unit of
FocalPlaneXResoluton/FocalPlaneYResolution: 1 means no-unit 2 inch 3 centimeter Note: Some of Fujifilm's digicams (e.g. FX2700, FX2900, Finepix 4700Z/40i, etc.) use value '3' so it must be 'centimeter', but it seems that they use a '8.3mm?' (1/3in.?) to their ResolutionUnit. Fuji's BUG? Finepix4900Z has been changed to use value '2' but it doesn't match to actual value either. |
|
| ExposureIndex | double | Same as ISOSpeedRatings (0x8827) but data type is unsigned rational. Only Kodak's digicam uses this tag instead of ISOSpeedRating. | |
| SensingMethod | integer | Shows type of image sensor unit. '2' means 1 chip color area sensor. Most all digicams use this type. | |
| FileSource | integer | Indicates the image source. Value '0x03' means the image source is a digital still camera. | |
| SceneType | integer | Indicates the type of scene. Value of '0x01' means that the image was directly photographed. | |
