Basic Operation and Features
Basler A500k Series 3-35
PRELIMINARY
3.9.1 Changes to the Maximum Frame Rate with Area of Interest
When the area of interest feature is used, the camera’s maximum achieveable frame rate
increases. The amount that the maximum frame rate increases depends on the number of lines
included in the area of interest. The fewer the number of lines in the area of interest, the higher
the maximum frame rate. The maximum achieveable frame rate can be calculated using the
following formula:
Where: LI = the number of lines included in the area of interest
*
In normal operation, the camera is set to use all of the pixels in the array. To use all
of the pixels, the starting column should be set to 1, the width in columns to 1280,
the starting line to 1 and the height in lines to 1024.
The setting for the width in lines and for the starting column must be divisible by 10.
The minimum width is 10.
The minimum height in lines is 2. The minimum starting line is 0.
The sum of the setting for the
starting column plus the setting for the width in col-
umns can not exceed 1281.
The sum of the setting for the
starting line plus the setting for the height in lines can
not exceed 1025.
For a color camera, the setting for the height in lines and for the starting line must
be divisible by two. The minimum height in lines is 2.
