Optimizing Image Quality

Different applications have different requirements in terms of image quality. By adjusting some settings using the pylon Viewer you can achieve good results quickly.

Focus

To get a focused image, consider the following:

Depth of Focus

If your objects are located at different distances from the camera, you must consider depth of focus. The depth of focus must be sufficiently deep to allow all objects to appear focused.

Brightness

The following factors determine the brightness of an image:

Illumination

Lens Aperture

Exposure Time

Gain

Black Level

Exposure Time

The exposure time setting determines the time interval during which the sensor is exposed to light.

Choose an exposure time setting that takes account of whether you want to acquire images of still or moving objects:

Gain

Gain amplifies each pixel readout by a certain factor. Accordingly, signal and noise are both amplified.

Contrast

Strong contrast in an image is obtained when objects of different brightnesses are represented by strongly different gray values. For most applications, optimum contrast is achieved when the image displays a wide range of gray values with fine detail remaining visible even in the darkest and brightest parts of an image. Some applications, however, may require extreme contrast.
