What is the primary purpose of interlaced scanning in video technology?

Interlaced scanning is primarily utilized in video technology to prevent flicker in displayed images. This technique works by capturing and displaying alternate lines of an image in sequence, which effectively reduces the perception of flicker that can occur when displaying full frames at lower refresh rates. As a result, the viewer experiences a smoother and more stable image, especially in low-light conditions or during fast-moving scenes.

While enhancing image sharpness, reducing bandwidth, and improving color depth may be important features in various video technologies, they are not the primary purpose of interlaced scanning. The method specifically targets the visual comfort of viewers by addressing flicker, thereby enhancing the overall viewing experience in environments where interlaced scanning is implemented.
