The iPhone is renowned for taking great photos. The iPhone 7 Plus has some new technology that promises to push phone photography to a new level that few have experienced.
From a photo standpoint, the exclusive feature on the iPhone 7 Plus is its dual-camera setup. This has been completed before by other phone creators with fluctuating results. But this is the first ever time it is being done in an iPhone, which gives a new kind of legitimacy in the industry. Other companies must now do something similar to Apple’s new camera just to keep up.
The iPhone 7 Plus contains both a f/1.8, 28mm wide-angle lens as well as a 56mm telephoto lens on the back. Slapping an additional lens and sensor on a cell phone doesn’t make it a better camera. A lens is as good as the sensor as well as processing pipeline behind it. The iPhone 7 have a 12-megapixel sensor behind its 28mm wide-angle lens, whereas the iPhone 7 Plus contains another 12-megapixel sensor just behind that portrait-friendly telephoto lens. These modules can minimize the blurriness of photos shot with the shaky hands.
The killer application on 7 Plus is a 2x optical zoom. If you tap an onscreen button to jump from wide angle to the telephoto lens. All smartphone cameras allow you zoom, but most use a digital zoom. That means the lens doesn’t change its position, the camera only enlarges the pixels in each photo for a bigger view. Such images damage as you increase the zoom. The fresh iPhone has digital zoom too, but because starting with 56mm telephoto glass, less degradation in resolution is seen as you start moving with the 10x digital zoom.
Apple iPhone 7 plus cameras: New signal processor.
The sensor in the 7 Plus is 12-megapixels, which Apple defines as “an entirely new camera”. But it doesn’t factor whether it’s the similar base unit as the 1/3 in size (1.22µm pixels) one in the iPhone 6S – we suspect that it is.
The main difference in the iPhone 7 is adding of a new image signal processor (ISP). Its double as rapid as before in its ability to read the scene and, so, decide how to respond with focus, noise reduction, tone, color and so forth. This approach is somewhat camera manufacturers often utilize between generations of camera promotions. It means marginal achievements in image quality from a processing point of view.
Apple opinions to its image signal processor as the secret weapon in its novel phone. In both the single-shooter iPhone 7 as well as the dual-lens iPhone 7 Plus, Apple entitlements this processor uses machine learning to scan the scene for faces and other identifiable objects, then pays specific attention to them when focusing as well as setting exposure. It also adjusts everything from the white balance to noise reduction to tone mapping. That’s not completely different from the processor in any other cell phone, just faster.
