Linea Lite GigE Series Camera

To evaluate a bare image of a uniform white target scene use the line profile tool shown below.

Figure 48: CamExpert Statistics Dialog – Line Profile

A line profile is mainly determined by two factors: Flatness and Height

1) Flatness: The Line profile represents a Flat Field measurement. Due to lens-shading effect,

light falls-off near the edges and results in lower output. This produces higher noise levels near the

edge. A smaller aperture opening and longer focal length can reduce lens - shading effect. In some

demanding applications, optimized low - shading lenses should be considered.

2) Height: An average value near your calibration target is ideal.

An extremely low output compared to the target will increase noise level significantly after the

PRNU is corrected. To avoid SNR and / or DNR not meeting your application requirements, the

profile should reach a level near the calibration target.

Note: Changes to gain do not improve image quality from a SNR perspective.

Gains are analog and digital multipliers that scale up signal and noise

proportionally.

Before performing a FFC follow these guidelines:

•

Ensure the camera’s temperature is at nominal operating condition. Power-on for minimum 30

min.
