Final answer:
The automatic brightness stabilizer is the electronic system designed to help maintain a consistent level of image brightness.
Step-by-step explanation:
The electronic system designed to help maintain a consistent level of image brightness is the automatic brightness stabilizer. This system is commonly found in digital cameras and flat screen LCD televisions.
In digital cameras, an automatic brightness stabilizer adjusts the exposure settings to ensure that the images captured have consistent brightness levels, regardless of lighting conditions.
In flat screen LCD televisions, the automatic brightness stabilizer controls the strength of the voltage applied to the liquid crystal cells in each pixel, allowing for adjustable picture contrast and maintaining a consistent level of image brightness.
