TECHNOLOGY OF 100× ZOOM LENS

 Samsung’s 100x zoom lens, also known as the “Space Zoom” lens, is an impressive technological feat that allows users to capture faraway objects with great detail. The lens, which is featured on Samsung’s Galaxy S21 Ultra smartphone, combines multiple lenses and sensors to achieve a high level of magnification. In this article, we will take a closer look at how the Samsung 100x zoom lens works.

First, let’s talk about the basics of a camera lens. A camera lens is designed to focus light onto a camera’s sensor, which then captures the image. The amount of light that enters the lens is controlled by an aperture, which can be adjusted to allow more or less light to enter the lens. The lens is also responsible for controlling the depth of field, which determines how much of the image is in focus.

A zoom lens, as the name suggests, allows the user to zoom in or out on the subject. Zoom lenses typically use a series of glass elements that move relative to each other to change the focal length of the lens. This changes the magnification of the image, allowing the user to get closer to or farther away from the subject without physically moving the camera.

The Samsung 100x zoom lens takes this concept to the extreme. It uses a combination of optical and digital zoom to achieve a magnification of up to 100x. Let’s take a closer look at how this works.

The lens system of the Samsung 100x zoom consists of four lenses, including a periscope telephoto lens. This lens is designed to reflect light at a 90-degree angle, allowing the lens to be oriented vertically within the phone. This is important because it allows the lens to be longer than the thickness of the phone, which is necessary for achieving a high level of magnification.

The periscope telephoto lens is made up of several lens elements that work together to focus the light onto the sensor. These elements include a prism that reflects the light and two lenses that correct for chromatic aberration, which is a common problem in telephoto lenses that causes color fringing around the edges of the image.

The periscope lens system is paired with a 108-megapixel primary camera sensor and a 10-megapixel telephoto sensor. The primary sensor captures the majority of the image, while the telephoto sensor is used for zooming in on the subject. The telephoto sensor has a longer focal length than the primary sensor, which allows it to achieve a higher level of magnification.

The combination of the periscope lens system and the telephoto sensor allows the Samsung 100x zoom lens to achieve a magnification of up to 100x. However, the lens doesn’t stop there. It also uses digital zoom to further enhance the magnification.

Digital zoom is a technique that uses software to zoom in on the image after it has been captured. This is different from optical zoom, which physically changes the magnification of the lens. Digital zoom can be useful for achieving a high level of magnification, but it can also result in a loss of image quality.

To mitigate the loss of image quality, Samsung uses a technique called “AI-powered zoom.” This technique uses artificial intelligence to analyze the image and enhance it in real-time. The AI algorithm is designed to remove noise and enhance details, resulting in a sharper image.

Another important aspect of the Samsung 100x zoom lens is image stabilization. When zooming in on a subject, even small movements of the camera can result in a blurry image. To combat this, Samsung uses a combination of optical and electronic image stabilization. The optical stabilization corrects for small movements of the lens, while the electronic stabilization corrects for movements of the sensor.

In conclusion, the Samsung 100x
