Periscope cameras are a significant advancement in mobile photography, enabling high-quality zoom capabilities without increasing the phone’s thickness. Here’s how they work:
– Periscope Lens: A periscope lens uses a prism or mirror to bend light at a right angle, allowing for a longer focal length without increasing the camera’s physical length.
– Optical Zoom: Periscope cameras offer optical zoom, which provides higher image quality compared to digital zoom. Optical zoom uses the lens to capture the image, while digital zoom crops and enlarges the image, reducing quality.
– High-Resolution Sensors: High-resolution sensors, like the 108-megapixel sensor in the Samsung Galaxy S20 Ultra, provide more detailed images and enable better zoom capabilities.
– Image Processing: Advanced image processing algorithms enhance the zoomed image quality, reducing noise and artifacts.
– Camera Setup: Periscope cameras are often combined with other lenses, such as wide-angle or telephoto lenses, to offer versatile zoom capabilities.
Key Benefits of Periscope Cameras
– High-Quality Zoom: Periscope cameras provide high-quality zoom capabilities without sacrificing image quality.
– Thinner Design: The periscope lens design allows for a thinner phone profile, making it more convenient to carry.
– Improved Portability: The combination of high-quality zoom and a compact design makes periscope cameras ideal for mobile photography.
Notable Devices with Periscope Cameras
– Samsung Galaxy S20 Ultra: Offers 100x zoom with its periscope lens and high-resolution sensor.
– Huawei P30 Pro: Features a periscope lens with 5x optical zoom and 50x digital zoom.
– Oppo Find X7 Pro: Expected to feature dual periscope lenses with 3x and 6x optical zoom capabilities.
