The first is the improvement of camera module hardware, and the other is the improvement of software algorithms. Without digital zoom, you can only compose the second composition after shooting, and the effect of the second composition cannot be seen directly when shooting, which is much less intuitive.Р В РІР‚СњР В РІР‚С›t present, the zoom capability of cameras in mobile phones is gradually improving. In addition, the digital zoom of the mobile phone can compose the picture in real time, and adjust the angle of your position to match what you see. The probability will be greatly increased, and your circle of friends will be even more compelling. It's like you could only shoot interesting things within 10 meters centered on you. On the bright side, the digital zoom on your phone can expand people's field of vision. The larger the magnification (digital zoom), the higher the quality. The reason is that the digital zoom does not change the size of the image on the photoreceptor by moving the lens (this is what optical zoom does), but it is achieved by cropping the image and then zooming in. Simply speaking, the selling point of digital zoom has been ruthlessly abandoned. Nowadays, home DV basically does not mention digital zoom, and SLR cameras even refuse to have a relationship with digital zoom. Card machines and home DV (digital video cameras) more than a decade ago were equipped with digital zoom as standard, and it was hundreds of times motionless. If it's just for fun, it can be used to satisfy curiosity, but if you want to take photos with 100x digital zoom, the quality of the film must be very average, after all, 100x digital zoom gimmicks are greater than practical.Р В РІР‚СњР вЂ™Р’Вigital zoom is not a new technology concept. The 100x zoom is the maximum zoom factor of the Samsung Galaxy S20 UItra, but not through optical zoom, but through digital zoom. Today, the digital zoom of mobile phones has been upgraded to 100 times. In fact, the usefulness of digital zoom on mobile phones is mainly determined by the needs of people who use it. Since the current mainstream optical zoom mobile phones cannot completely guarantee that the photos taken are not damaged, what value does the high-power digital zoom of the mobile phone have? What's the point of a mobile phone's high digital zoom? That is, it has multiple lenses including wide-angle and telephoto, and through the cooperation between each other, it uses algorithms to simulate and realize the zoom in and zoom out of the screen.Р В РІР‚СњР В РІР‚РЋrom the perspective of the imaging quality of mobile phone zoom, optical zoom> hybrid zoom> digital zoom. So now what we call optical zoom phones are basically algorithmic zooms. Phones like the Samsung Galaxy S4 Zoom are not mainstream.

In the age of mobile phones, the concept of optical zoom has been subdivided into 'physical optical zoom' like Samsung Galaxy S4 Zoom (the principle is the same as digital cameras), and 'algorithmic zoom' such as iPhone 8 Plus or Huawei P20 Pro (also May be called 'hybrid optical zoom').Р В РІР‚СњР В РІР‚С›t present, mobile phones with physical optical zoom on the market are basically extinct, because even the 5x lossless zoom technology of OPPO is not really 'lossless', it is actually achieved by 3x optical zoom + digital zoom. This is why optical zoom is also called non-destructive zoom. The latter is to 'zoom in' or 'zoom out' of the subject by moving the lens within the lens.Р В РІР‚СњР вЂ™Р’В®ntering the era of digital cameras, zoom is split into optical zoom and digital zoom.Р В РІР‚СњР вЂ™Р’Вigital zoom is also well understood, that is, the picture is cropped by the processor of the mobile phone, and the purpose of 'zooming in' is achieved at the expense of image quality. To change the composition and picture, you can only 'realize' by approaching or walking away. The former focal length was fixed, such as 50mm. In the era of film machines, there was only optical fixed focus and optical zoom. We try to make it clear to everyone in a simple and direct way. The concept of zoom is still very vague to everyone.
