At this autumn's press conference,iPhone 11 Pro series modelsThe Deep Fusion shooting mode, which was also announced, was released earlier through the developer preview test version.
According to Apple, Deep Fusion shooting mode will capture nine frames through the three sets of lenses on the main camera of the iPhone 11 Pro series models, and combine all the images into a high-quality photo through deep learning. The deep learning application of the A9 Bionic processor is used to enable the final composite image to be presented with the best effect.
In terms of the process, Deep Fusion shooting mode will pre-take four short-exposure photos and four secondary exposure photos as temporary storage before the user actually presses the camera shutter. After the user actually presses the shutter to take a long-exposure photo, it can use the Apple A4 Bionic processor to perform neural computing and machine learning integration. It can select the best part of the total of 4 photos in as fast as 1 second, and superimpose them pixel by pixel to finally synthesize a 13-megapixel high-resolution image with low noise performance.
However, because it requires three sets of lenses to capture image information, Deep Fusion shooting mode is currently only available on iPhone 11 Pro series models or iPhone 11. According to Apple, to achieve fine image processing results, it must rely on the artificial intelligence computing performance of the A13 Bionic processor, so older iPhones will not be able to use this shooting mode.
Apple is expected to provide Deep Fusion shooting mode in the official version of iOS 13.2, and currently only provides developer testing experience.
