Selecting TDI or Area Mode Operation
The Piranha HN-xx camera has the ability to operate in either TDI or Area Mode.
In Area Mode, the camera operates as an area array camera using a two dimensional array of pixels. Area
Mode is useful for aligning the camera to your web direction or when you need a rectangular 2D image
and the lighting supports a full frame imager.
In TDI Mode, the camera operates as a TDI high sensitivity line scan camera and combines multiple
exposures of an object into one high-resolution result.
The camera stores user settings for Area Mode and TDI Mode separately, allowing you to switch between
Area and TDI mode without losing settings specific to each mode. See
an explanation on how user settings are stored and retrieved.
Note:
Sensor cosmetic specifications for Area Mode of operation are neither tested nor guaranteed
Purpose:
Selects the camera's operating mode. Area Mode is useful for aligning and focusing your
camera.
