CAMLEVEL (Statement)


Set the camera image input level.


CAMLEVEL <camera number>,<lower limit level>,<upper limit level>


<camera number>
Specifies the camera number (1 or 2).
<lower limit level>
Specifies the lower limit level for reading camera images (0 to 93).
<upper limit level>
Specifies the upper limit level for reading camera images (7 to 100).
  • This statement specifies the input range between the lower limit of 0% and the upper limit of 100%.
  • The range that has been specified is divided into 256 intensity levels.
  • It is necessary that the setting be between 0 ≤ lower limit value < upper limit value ≤ 100 and upper limit - lower limit ≥ 7.
  • To obtain more detail image information, use this statement to adjust a dark image or bright image, or to partly increase the resolution of the brightness.
  • If you do not make a setting with this statement, the initial setting values apply.
  • This statement does not change the initial setting. If you restart the system after powering OFF, the set values are lost.
  • To execute this statement, a µVision board (option) is required.
  • This statement takes effect at execution of the next camera input statement (CAMIN).
