These days, almost every camera with a built-in lens has some sort of a “zoom” label on it. However, not all types of zoom are created equal, especially if you include cell phone cameras. There are two major different technologies that are used: digital zoom, and optical zoom. What’...
变焦:包括光学变焦(optical zoom)与数码变焦(digital zoom)两种。两者虽然都有有助于望远拍摄时放大远方物体,但是只有光学变焦可以支持图像主体成像后,增加更多的像素,让主体不但变大,同时也相对更清晰。数码变焦只能将原先的图像尺寸裁小,让图像在lcd屏幕上变得比较大,但并不会有助于使细节更清晰。 广角:指代摄影的...
This is why digital zoom often gets a bad rep when compared to optical zoom. However, in recent years there have been advancements in digital zoom, often using software. An image may be scaled up by the camera using interpolation (adding made up pixels back in, using the camera’s ...
Tech Corner: Digital zoom vs. optical zoomBuntin, James
35 mm camera will be aware of optical zoom. This is where you use the optics of the lens to bring the subject closer. Digital zoom, on the other hand, is something that has only been invented with digital video cameras and isn’t zoom in the traditional sense such as in optical zoom...
Optical vs. digital zoom? There is no contest. Only optical zoom matters when selecting a digital camera. What we are really trying to say is this: do not compare. You’ve got to decide what is more important to you: resolution or optical zoom? If the answer is both, then find a di...
Both optical zoom and digital zoom are used in embedded vision cameras. Learn their similarities, differences, working principle, and embedded vision applications in detail.
Optical and digital zoom are two very different ways to snap a closer photo without moving your feet. Optical zoom — the only zoom that’s really worthwhile — means the camera can zoom using physical lens parts, while digital zoom means the camera uses software to “zoom.” ...
Watch this video to compare digital zoom vs optical zoom functions using a 4K fixed lens security camera and a 4mp pan tilt zoom camera (PTZ). What is digital zoom? Digital zoom uses a fixed lens security camera and magnifies the pixels in a certain area of image (the zoom area) and ...
