Digital zoom
What is digital zoom?
Digital zoom is a camera function that enlarges an image by cropping and magnifying the pixels, rather than physically adjusting the lens. Unlike optical zoom, which maintains image quality by using a camera’s lens to magnify a scene, digital zoom can result in pixelation and reduced clarity, especially at high magnification levels. Digital zoom is commonly used in security cameras, smartphones, and digital photography to get a closer view of distant objects when optical zoom is not available. Businesses use digital zoom in security systems to analyze footage, but higher-resolution cameras are recommended to minimize image distortion when zooming in.

Why is digital zoom important?
Digital zoom is important because it allows cameras to enlarge distant objects without the need for a physical zoom lens. In security systems, digital zoom helps businesses and law enforcement review footage more closely, aiding in the identification of faces, license plates, and suspicious activity. In smartphones and digital cameras, it provides a convenient way to get a closer view of a subject when optical zoom isn’t available. However, because digital zoom enlarges pixels rather than capturing more detail, image quality can decrease at higher zoom levels. To minimize distortion, businesses and photographers often pair digital zoom with high-resolution cameras to maintain clarity when zooming in.
