Camera Operation

Linea CLHS Series Camera

Pixel Readout Direction (Mirroring Mode)

The Line Mirroring feature, in the

Image Format

category, sets the tap readout from left to right

or from right to left. This feature is especially useful if you want to mount the camera “upside

down.”

Description

Line Mirroring

Off: All pixels are read out from left to right.

On: All pixels are read out from right to left.

Area of Interest (AOI) Setup

The Area of Interest (AOI) feature can be used to reduce the amount of image-data output from

the camera. Use this feature when there are areas in the image that contain unneeded information.
An example where you would use this feature is in an application that is inspecting several

separated lanes of objects with one camera and the image between the lanes can be ignored.
The AOI feature allows from one to four specific areas of the pixel line to be specified where image

data will be output. Since the AOI feature reduces the amount of data output, this has the

additional benefit of allowing the cameras to operate at higher line rates when using base or

medium camera link modes.

Note:

The setup of AOI is always with respect to the sensor. Therefore, if you are using the

mirroring mode with AOI, be aware that pixel one will be on the right side of the displayed image.

The AOI commands are grouped in the Image Format category.

To set up an AOI for the camera:

•

The AOI mode must first be in the off position.

•

Use the AOI Count to select the total number of AOIs desired to a max of 4.

•

To set up each AOI individually use the AOI Selector to point to the AOI to be set up.

•

AOI Offset X is used indicate the starting pixel of the AOI. The starting pixel of the region

must be 1 + a multiple of 8 (base, medium, and full modes) or 10 (deca mode).
