Why is the screen recorded by Apple clearer than that recorded by Android?

1. Apple iPhone has a strong core.

Computing power is the most important indicator of mobile phones. Apple's mobile phone processor has always been at the top of the industry, which is simply a godlike existence. No matter when it is released, the core device of Apple's mobile phone is the most powerful. Take iPhone 13 as an example, its A 15 processor is recognized as the strongest processor at present. Snapdragon 8, Kirin 9000 and Tianji 9000 should all be in the back row.

Powerful CPU and GPU processing power is the benchmark to measure the performance of a mobile phone, which provides the most basic performance guarantee for Apple's cameras and videos. The A-series bionic chip of iPhone can intelligently adjust the white balance, contrast, saturation and overall texture of photos through machine learning, making the photos taken more natural.

2. Apple's excellent system tuning and algorithm.

Apple's excellent system tuning and algorithm are recognized by everyone. This is why the memory of iPhone4-6G is faster than that of Android 8- 12G. IPhone IOS unified memory architecture, integrating everything into the same high bandwidth and low latency memory pool. Access the same data without copying back and forth between multiple memory pools. The speed is obvious.

IPhone can maximize the performance of the lens module, so that the camera's photosensitive elements and pixels have an optimal matching degree, and the effective pixels are as large as possible. In this respect, although Android has large pixels, its effective pixels are not high. In addition, pixels only determine the effect of enlarged images, not the imaging quality. Therefore, the comprehensive utilization rate of the hardware of the iPhone is high, rather than blindly stacking high configuration.

3. Professional image signal processing (ISP) is the main factor of excellent Apple video.

Apple started from playing with image processing, and video processing is its strength. A large number of continuous data processing makes the powerful capabilities of Apple chips seem handy, such as ultra-wide, wide-angle, and follow focus. Make sure that the video zoom is clear and will not get stuck when switching lenses. IPhone 13 has the characteristics of large depth of field and good focus, and supports film special effects mode to shoot video with shallow depth of field.

Each sensor of iPhone takes both video and still images into consideration, and never adds up in pixel and focal length design. The powerful ISP and algorithm of A series chips are connected in series with software and hardware, and the SoC performance is stable. Coupled with Apple's deep accumulation in the field of video processing for many years, it is impossible to be strong. It is said that many of Apple's R&D and designers are photographers, and their own control of image color is first-class.

However, domestic Xiaomi's ISP professional imaging chip 2855438+0 and OPPO's self-developed NPU chip Mariana X have just been released, and there is still a lot of room for optimization in performance.

4. The influence of the size and quality of the photosensitive element.

Apple has been using the12 megapixel camera since the iPhone6s, and its performance has been excellent, not losing Android! The photosensitive element is the hero! The photosensitive element is also called an image sensor, and its size and quality are important factors affecting the final imaging effect. The photosensitive element is a small plate that receives light, and the image quality depends on the amount of light it captures.

Compared with most Android machines under 5000, the display of MAC on the screen and photosensitive elements is more delicate and realistic. MAC uses a top-level screen, and through its own customized sensors such as Sony, it increases the unit pixel area and has a higher signal-to-noise ratio. Coupled with its own intelligent HDR video algorithm, the video shooting effect is far from the Android machine. Android can't compare!

Summary:

At present, Android mobile phone manufacturers have made remarkable progress in taking photos, but there is still a big gap in video. Video shooting needs to be recorded frame by frame, which requires not only a powerful processor, but also a powerful software analysis ability to meet the requirements of higher sampling rate, higher number of frames and better dynamic range.

The effect of video shooting is the result of the cooperative work of processor, sensor and algorithm. Domestic Android phones still have a long way to go to surpass Apple's shooting effect.
