8.19 White Pixel
If you use a VC-25MC or VC-25MC2 camera under the condition of high ambient temperature, white pixels (also
known as hot pixels) may be occurred due to the characteristic of equipped high resolution CMOS sensor.
White pixels are caused by accumulated current leakage in the charge storage region inside the imaging
sensor
’s active pixel. If temperature is increased by seven degrees, it is getting worse with double white pixels.
To effectively reduce white pixels, maintain the operating temperature as low as possible and mount the camera
on a substantial metal component in your system to provide sufficient heat dissipation. You can also use the
defective pixel correction to remove white pixels. Add a defective pixel to defective pixel map or modify the
defective pixel map stored in the camera.
