IDS Software Suite 4.96.1

During camera assembly, IDS Imaging Development Systems GmbH calibrates each sensor to determine its hot pixels, which are caused by technical reasons (see also Camera basics: Sensor: Hot pixels). In some cases, users may wish o extend this factory calibration. Using the uEye Hotpixel Editor, you can now edit the sensor hot pixel list stored in the camera.

The uEye Hotpixel Editor can be accessed as follows:

•Start > All programs > IDS > uEye > uEye Hotpixel Editor

After program start, the uEye Hotpixel Editor shows the following window:

In the toolbar on the top the following functions are provided:

•Open camera
Opens the camera that is marked in the camera list.

•Close camera
Closes the camera that is marked in the camera list.

•Hot pixel correction
Turns the hot pixel correction on/off.

•Detect hot pixel
Opens the dialog for the automatic hot pixel detection.

•Write hot pixel
Writes the list of the hot pixel to the non-volatile camera memory.

•Add hot pixel
Writes the marked hot pixel in the hot pixel list of the program.

•Delete hot pixel
Deletes a hot pixel from the hot pixel list of the program.

•Highlight
Inidicates if existing hot pixels should be marked.

•1:1
Zoom factor of the shown image.

Camera and hot pixel list

Below the menu bar on the left side there are the camera and hot pixel lists. In the camera list the found cameras with their status are displayed. Via the context menu camera can be opened and closed. Cameras with the status "in use" cannot be opened because they are already open in another application.

In the hot pixel list the hot pixels are displayed. The hot pixels are classified as "user" when they are added by the user. In contrast hot pixels are classified as "ignore" when they were saved while assembly.

Magnifier function

Via the magnifier you can mark hot pixels exactly. Below "Value" the value of the marked pixel is shown.

Camera properties

Here, you can change the settings to see hot pixels better. The program sets the exposure time automatically up and the master gain to 50. Note that the frame rate is limited to lower values.

Detecting hot pixel automatically

Via you open the "Hot pixel detection" dialog. Here, you have the possibility to search automatically for hot pixels and add them to the user list.

•Below "Threshold" you specify the threshold, that is how much a pixel must be differ from other pixels to be obtained as hot pixel. The higher the value, the more the pixel must be different. The uEye Hotpixel Editor uses the average of all pixels of the last 10 images as reference for the threshold value.

•The "Clear old hotpixel list" option removes the old user list before the search.

The number of hot pixels is limited which can be written to the non-volatile camera memory. It may happen that you found too many hot pixels. If this happens, you must change the threshold by increasing the "Threshold" value.
