Shoot two different angles at the same time:
According to Apple’s patent documents, Apple plans to use the dual camera lens design to add a dual shooting angle function, such as one lens is shooting a panorama At the same time, another lens can take a close-up shot of the same subject without wasting a moving moment.
True multiplex lossless zoom:
The biggest disadvantage of camera lenses on mobile phones is that when shooting distant objects, when zooming in to shoot, the shooting quality will be greatly reduced. Basically, it is just Forcibly magnifying part of the captured image, the dual-camera lens design can truly achieve limited lossless zoom. Using the cooperation of two lenses, two photos are taken at the same time and combined to achieve the effect of lossless zoom.
More powerful HDR:
In the past, HDR on mobile phones only took multiple photos with different exposure brightness at high speed and then combined them. The biggest disadvantage is that because it shoots in continuous shooting, there is a chance of image afterimages appearing when shooting high-speed moving images.
With the cooperation of two lenses, two different images can be shot at the same time. More importantly, two images with different exposures are taken at the same time, making the images clearer and less blurry. There will be image retention issues like in the past.
HDR video shooting function:
At present, with the cooperation of some software, some mobile phones can already shoot HDR videos, but the effect is not ideal, but with two lenses, The two lenses can work together to shoot two videos with different exposure brightness, and then combine them into a 4K HDR video.
3D shooting technology:
Currently, 3D videos are still not very popular, but the main reason is because there is a serious shortage of 3D shooting lenses on the market, especially for consumer products. Although HTC has A mobile phone product with dual-camera lens 3D shooting function was launched, but it failed because the shooting quality did not meet expectations.
