• Type in the new camera pixel scale value.

• Verify that the Pixel Units are set correctly, change as required.

• Double-click inside the Camera type edit text control.

• Type in a new 8 character file name. The .cam extension will automatically be added if

you fail to include it.

• Click on Save CAM...

• If the file path and name specified is correct, click OK.

• You will return to the Camera dialog box. Click OK.

Your new camera is now active, and saved as a <camera>.cam type file.

Note: You may now also want to perform a Save Config... operation, so that when you restart the LBA-PC

application, this new camera setup will automatically be restored. Otherwise, you must return to the Camera

dialog box and select this camera type each time you restart the LBA application.

Notice: A Restore Config... operation will occur each time the LBA application is started. Camera type selections

will only occur when you the operator consciously, unconsciously, but not sub-consciously..., make a choice. Which

ever of the above actions occurs last, is the one that is controlling the Camera dialog box settings.

3.2.3.3 Resolution and Frame Size

The Resolution value specifies how finely the incoming video image is to be digitized. This will

also determine the maximum frame size when viewing an un-zoomed image. The Resolution

value is not related to the resolution performance of your camera.

The smaller the Resolution value, the higher the resolution of the display, and the greater the

number of pixels that will be contained in the un-zoomed image. Consequently, each frame will

take more memory in the frame buffer and on disk, and it will take longer to process the frames,

thus the system will run slower.

The Resolution value will control how much memory is allocated for each frame. This figure does

not change dynamically as you zoom in. In other words, if you set the resolution to 1x, a frame

size of 512x480 is reserved in memory for each frame that is digitized. If you then hardware

zoom in twice, to a frame size of 128x120, you will be wasting 93.75% of each reserved frame

buffer locations space, since a 120x128 image is only 1/15th the size of a 512x480 image.

Thus, you should never specify a resolution that is more than what you need to do the job at

hand. Otherwise, you will waste system resources and reduce your overall throughput.

Analog camera image sizes are fixed to resolution values per the following table:
