6.5.5 DecimationHorizontal
Description: Horizontal sub-sampling of the image.
Access
Read / Write
Type:
Unsigned Integer
In:
1 … 2
Out:
Current horizontal decimation factor
Remark:
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
DecimationHo
rizontal
. 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 ho
rizontal 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 hori
zontal direction by factor 2 but covering the whole horizontal senor width.
6.5.6 DecimationVertical
Description: Vertical sub-sampling of the image.
Access
Read / Write
Type:
Unsigned Integer
In:
1 … 255
Out:
Current vertical decimation factor
Remark:
This value defines that each Nth image line in vertical direction must be sampled to build the im
age. So the size of the image gets reduced in vertical direction by the factor of
DecimationVertical
.
A decimation factor of 1 means no horizontal decimation. The
Height
value must be set to the re
quested number of lines.
Height
*
DecimationVertical
may not exceeds the max. vertical sensor
size or an error gets returned.
Example
: To get a sub sampled image which covers the whole vertical sensor height but uses
just the half number of lines you have to set the
Height
parameter to
SensorHeight
/ 2 and the
DecimatinVertical
factor to 2. This will result in an image which is clinched in the vertical direction
by factor 2 but covering the whole senor in vertical direction.
