Binning, subsampling or scaler increase the frame rate, without changing the field of view.

Sometimes less means more – Subsampling, binning, or scaler

Your field of view should not change but the frame rate should be increased? You need a shorter exposure? Will a lower resolution with the same field of view do for you?

To reduce the image resolution and still having the same field of view, you have different ways depending on the sensor model: subsampling, binning, or scaler. But how do they differ?

The key to contrast and detail: Adjusting the black level

There is white in your image but the image looks flat? Though you have darken your camera completely you do not get black? Or is there too much black in the image and details disappear?

Besides gain, gamma and color saturation also the black level plays a role in image reproduction. A poor black level affects the dynamic range and therefore the image impression. Only if a camera reproduces black and white the full dynamic range is ensured.

The same image and yet different - using the sequence AOI

For the camera models UI-124x / UI-324x / UI-524x and UI-125x / UI-325x / UI-525x with e2v sensors, there is a special IDS feature available: the sequence AOI mode.
The sequence AOI mode allows you to capture, for example, the same scene using different parameter sets (exposure, gain, etc.). It is useful for a variety of applications, for example, you can use it in applications with unknown light or brightness conditions.

Pixel preprocessing or RAW format? As you like it.

Depending on the application, the image data must fulfill different requirements. If you take a fast snapshot, you want a ready-to-use image from the camera. The image should look as good as possible and should not require any further postprocessing.
The pixel preprocessing in the camera hardware offers many advantages, in particular for embedded systems. Here, packed color formats, among others, can be used for data transmission.

Dust and dirt do not stand a chance – free view due to camera filters

To achieve optimum image quality the sensor needs to be kept free of dust. As pixels today are the same size as dust particles or even much smaller, a single speck of dust on the image sensor can drastically reduce the quality of the image.

The short distance to the pixel means that under certain lighting conditions a speck of dust on the image sensor can cast the pixel beneath it entirely in shadow. The speck of dust appears as a dark spot in the camera image.
