Table C.8.12.11-1 specifies the Attributes of the VL Photographic Acquisition Module, which describe the process of acquisition of a photographic image.
Table C.8.12.11-1. VL Photographic Acquisition Module Attributes
The chromaticity of the white point of the image. This is the chromaticity when each of the primaries has its reference white value. The value is described using the 1931 CIE xy chromaticity diagram. |
|||
The chromaticity of the three primary colors of the image. This is the chromaticity for each of the primaries when it has its reference white value and the other primaries have their reference black values. These values are described using the 1931 CIE xy chromaticity diagram. |
|||
A description of the camera’s battery level at the time of image capture, encoded as a decimal, ratio, or text string. |
|||
The number of rows in the Opto-Electronic Conversion Function (OECF), as specified in [ISO 14524]. |
|||
The number of columns in the Opto-Electronic Conversion Function (OECF), as specified in [ISO 14524]. |
|||
The names of the columns in the Opto-Electronic Conversion Function (OECF), as specified in [ISO 14524]. |
|||
The values of the Opto-Electronic Conversion Function (OECF), as specified in [ISO 14524], encoded as successive column values of the first row, then as successive column values of each successive row. |
|||
The number of rows in the Spatial Frequency Response (SRF) table as specified in [ISO 12233]. |
|||
The number of columns in the Spatial Frequency Response (SRF) table as specified in [ISO 12233]. |
|||
The names of the columns in the Spatial Frequency Response (SRF) table as specified in [ISO 12233]. |
|||
The values of the Spatial Frequency Response (SRF) table as specified in [ISO 12233], encoded as successive column values of the first row, then as successive column values of each successive row. |
|||
The number of rows in the color filter array (CFA) geometric pattern. |
|||
The number of columns in the color filter array (CFA) geometric pattern. |
|||
The values of the color filter array (CFA) geometric pattern of the image sensor when a one-chip color area sensor is used, encoded as successive column values of the first row, then as successive column values of each successive row. |
|||
The class of the program used by the camera to set exposure. |
|||
The spectral sensitivity of each channel of the camera used. The value is an ASCII string compatible with the standard developed by the ASTM Technical Committee. |
|||
The sensitivity of the camera or input device, as specified by the [ISO 12232] parameter selected by Sensitivity Type (0016,001A). |
|||
Which of the parameters of [ISO 12232] is used in Photographic Sensitivity (0016,0018). |
|||
The standard output sensitivity value of a camera or input device defined in [ISO 12232]. |
|||
The recommended exposure index value of a camera or input device defined in [ISO 12232]. |
|||
The ISO speed value of a camera or input device that is defined in [ISO 12232]. |
|||
The ISO speed latitude yyy value of a camera or input device that is defined in [ISO 12232]. |
|||
The ISO speed latitude zzz value of a camera or input device that is defined in [ISO 12232]. |
|||
The smallest F number of the lens. The unit is the APEX value. |
|||
Defined Terms:
|
|||
The detection of returned light from firing of the flash (strobe light). Defined Terms: |
|||
Whether or not the camera has a flash function flash (strobe light). |
|||
The location and area of the main subject in the overall scene. If two values are present, they are the X and Y image-relative coordinates of a location. If three values are present, they are the X and Y image-relative center coordinates and the diameter in pixels of a circle. If four values are present, they are the center X image-relative coordinate, the center Y image-relative coordinate, the width in pixels, and the height in pixels of a rectangle. The coordinate values, width, and height are expressed in relation to the upper left as origin. |
|||
Any desired information. The contents are up to the manufacturer. |
|||
The water depth at the time of acquisition, in m. When the value is negative, the absolute value of it indicates the height (elevation) above the water level. |
|||
The acceleration as a scalar, regardless of direction, at the time of acquisition, in mGal (10-5 m/s2). |
|||
The elevation/depression (angle of the orientation of the camera, imaging optical axis) in degrees from -180 to less than 180, at the time of acquisition. |
|||
The amount of flash (strobe) energy at the time the image is captured, in Beam Candle Power Seconds (BCPS). A single value if the exact flash energy is known, otherwise two values, the minimum value and the maximum value. |
|||
The location of the main subject in the scene. The value of this tag represents the pixel at the center of the main subject relative to the upper left corner. The first value indicates the X column number and second indicates the Y row number. |
|||
The exposure index selected on the camera or input device at the time the image is captured. |
|||
The equivalent focal length assuming a 35mm film camera, in mm. |
|||
The direction of saturation processing applied by the camera. |
|||
The direction of sharpness processing applied by the camera. |
|||
Information on the picture-taking conditions of a particular camera model, encoded as defined in [EXIF 2.31]. |
|||
The number of seconds the image capture was delayed from when the capture was initiated by the camera operator. If the value is zero, the self-timer is off. |
|||
Identification of the interoperability rule to which the image conforms. Defined Terms:
|
|||
The version interoperability rule to which the image conforms. |
