Height
This feature provides the image height in lines.
Access read / write
Type: unsigned integer
In: 2 … HeightMax
Out: image height
Remark: the maximum value of this feature equals to HeightMax – OffsetY; image height must
be incremented by 2 lines
DecimationHorizontal
Horizontal sub-sampling of the image
Access Read / Write
Type: Unsigned Integer
In: 1 … 2
Out: Current horizontal decimation factor
Remark: incremented by 1;
This value defines that each Nth image pixels in horizontal direction must be sampled to
build the image. So the size of the image gets reduced in horizontal direction by the
factor of
DecimationHorizontal
. A decimation factor of 1 means no horizontal decimation.
The
Width
value must be set to the requested number of horizontal pixels.
Width
*
DecimationHorizontal
may not exceeds the horizontal sensor size or an error gets
returned.
Example
: To get a sub sampled image which covers the whole horizontal sensor width
but uses just the half number of horizontal pixels you have to set the
Width
parameter
to
SensorWidth
/ 2 and the
DecimatinHorizontal
factor to 2. This will result in an image
which is clinched in the horizontal direction by factor 2 but covering the whole
horizontal senor width.
