How many hot pixels are on the camera's internal list depends above all on the defined threshold values. It is not
an indication of the quality of the sensors used.
When you enable the "Hotpixel correction" function in the DCx software, the software automatically corrects the hot
pixels in the captured image by calculating the average from the brightness value of two neighboring pixels. When
using color sensors, the hot pixel is corrected with the appropriate color in raw Bayer format, i.e. before color
conversion. The correction does not work with activated subsampling and binning factors greater than 2x.
Note
The sensors are tested during manufacturing also for cold pixel and dead pixels. Sensors with dead pixel clusters
(more than two neighboring defective pixels of the same color) are rejected by our quality control. When the
camera is operated in very warm ambient conditions, other defective pixels can occur, however.
Defining additional hot pixels
If additional hot pixels occur during use of the camera, you can add them to the camera's internal hot pixel list. To
do this, use the API function given below.
