Gain refers to the amplification of the signal from the image sensor to ensure that the imaging process meets defined purposes. However, trade-offs may occur in some cases. Learn about the types of gain, their differences, and their relationship with image quality.

Gain plays a major role in shaping the final image output captured by embedded vision systems. It refers to the amplification of the signal originating from the image sensor, similar to adjusting the volume on a speaker. These adjustments help optimize the imaging process for specific purposes, such as low-light scenarios, high-speed applications, unpredictable environments, and more.
