Field Value

Return Value

The SensorType enum value of the camera sensor

Remarks

Must be implemented, must not throw an ASCOM.PropertyNotImplementedException.

SensorType returns a value indicating whether the sensor is monochrome, or what Bayer matrix it encodes. The following values are defined:

ValueEnumerationMeaning
0 Monochrome Camera produces monochrome array with no Bayer encoding
1 Colour Camera produces color image directly, requiring not Bayer decoding. The monochome pixels for the R, G and B channels are returned in this order in the ImageArray.
2 RGGB Camera produces RGGB encoded Bayer array images
3 CMYG Camera produces CMYG encoded Bayer array images
4 CMYG2 Camera produces CMYG2 encoded Bayer array images
5 LRGB Camera produces Kodak TRUESENSE Bayer LRGB array images

Please note that additional values may be defined in future updates of the standard, as new Bayer matrices may be created by sensor manufacturers in the future. If this occurs, then a new enumeration value shall be defined. The pre-existing enumeration values shall not change.

In the following definitions, R = red, G = green, B = blue, C = cyan, M = magenta, Y = yellow. The Bayer matrix is defined with X increasing from left to right, and Y increasing from top to bottom. The pattern repeats every N x M pixels for the entire pixel array, where N is the height of the Bayer matrix, and M is the width.

RGGB indicates the following matrix:

X = 0X = 1
Y = 0 R G
Y = 1 G B

CMYG indicates the following matrix:

X = 0X = 1
Y = 0 Y C
Y = 1 G M

CMYG2 indicates the following matrix:

X = 0X = 1
Y = 0 C Y
Y = 1 M G
Y = 2 C Y
Y = 3 G M

LRGB indicates the following matrix (Kodak TRUESENSE):

X = 0X = 1X = 2X = 3
Y = 0 L R L G
Y = 1 R L G L
Y = 2 L G L B
Y = 3 G L B L

It is recommended that this function be called only after a connection is established with the camera hardware, to ensure that the driver is aware of the capabilities of the specific camera model.

Exceptions

ExceptionCondition
NotConnectedExceptionMust throw an exception if the information is not available. (Some drivers may require an active connection in order to retrieve necessary information from the camera.)
