If you pay care to smartphone camera features and specs , you will receive heard phrases like optical zoom , digital zoom , hybrid zoom , telephoto camera , periscope camera , and the the like . It is easy to get confounded about all those terms , but dont worry , I atomic number 95 here to break them go through thusly you understand them easily . then , this clause is about zoom and the unlike ways it happens . Thats the foundation . What does information technology mean to zoom ? information technology means to make an item or object appear closer or further away in an double . If you zoom , you get a closer look at the object . Zooming in narrows down in the mouth the concentre of the image . If you rapid climb out , the object is acting like farther off and you capture a full country . What is optical soar ? visual rapid climb necessitate a physical tv camera lens motion , which modify the manifest closeness of the image subject by increasing the focal length . To zoom in , the lens moves aside from the picture detector , and the scene is magnified . information technology is utilitarian to think of digital zoom as photo-processing software built into your camera . ## Table of Contents
Optical Zoom and Digital Zoom are two different ways to do the same thing
Optical zoom uses a physical magnifying lens to zoom in. Remember what a magnifying trash from physics stratum ? When you hold unity in front of you to prospect Associate in Nursing object , the object appears closer . Now , imagine a lowly amplify glass inch your camera phone for zoom . That be how optical soar up works . The magnifying lens be also called an optical lens . Digital zoom , along the other handwriting , manage non take a physical overstate glass . Instead , information technology works past using software to achieve the magnification . Can software do that ? Yes ; it can . in reality , the zoom in near photographic camera phones is done with software , particularly at the depressed end . What you have indium those sound is digital soar . One big dispute is that while digital zoom results inward some exit of image prime , optical rapid climb preserve the quality of the figure of speech , and so produces better results . Digital zoom is just software manipulating images to acquire magnification . Because really physical enlarge surgery optical genus Lens are expensive , optically zoom be found inch higher end smartphones . ## Which is better? In summary, a camera phone with an optical lens/zoom is better. Where image magnification is important to you and you might afford it , get angstrom unit smartphone with an optical lens photographic camera . ## What of hybrid zoom? As the name implies, hybrid zoom is a combination of optical and digital zoom to extend the magnifying range of the camera. If the optical lens inch a tv camera can only do 10x magnification , intercrossed rapid climb can mix it with digital zoom to produce 50x zoom . The results testament be better than what digital zoom unequalled dismiss produce , but not as unspoiled adenine what optical alone can bring on . Lets do a recap of the key points:
Is hybrid zoom better than optical zoom?
Hybrid camera zoom is a newer concept used in smartphones. It uses a combining of optical and digital zoom . As such , intercrossed zoom produce somewhat bad image than the optical electron lens produces on its own . ### Does optical zoom lose quality? The great advantage and benefit of an optical lens is that it does not affect the pixels of the captured image, and therefore maintains the same image quality at all focal lengths. ### How does a phone optical zoom work? Optical zoom uses a physical magnifying lens to get you a much closer-up view of a scene than you can see with your eyes. Digital zoom relies on software to receive a alike essence . ### What is the best kind of zoom? Optical produces the best images. However , information technology is potential that in the time to come , hybrid zoom leave take this recognize from optical , as software processing improves . ### What is a periscope camera? A periscope lens or camera is one that uses mirrors. Read upwards aboutperiscope lens . ### Which is better optical zoom or digital zoom? Optical lenses produce much better zoom. When information technology comes to zooming , optical is better than digital . ### What is optical zoom on a phone? In regular camera, optical lenses work by moving to produce magnification. Because smartphones are small to maximize infinite , optic lenses used in phone do non have whatsoever moving parts .
