Q&A: I want to buy a mobile phone with a good photo. What should we focus on?

In recent years, mobile phone photography has become more and more powerful in terms of image quality and gameplay, and even the sound of mobile phone photography surpassing SLR has become stronger and stronger. Indeed, mobile phone cameras have incomparable advantages over SLR cameras in portability and playability. In more and more scenes, users will choose to abandon the SLR and use their mobile phones for photography and video recording. Then, users often ask, I want to buy a mobile phone with a good photo. What should I focus on?

The ass is too big, crushing people. -The bigger the bottom, the better the picture.

There is often a saying in the camera circle that "the ass is big enough to crush people." The core of the camera is the area of the photosensitive element, commonly known as the "bottom". Recently, Lei Jun also popularized this knowledge in Weibo. The larger the area of the photosensitive element, the greater the amount of light entering. Under the same ambient light, the greater the light input, the lower the iOS, the less the image noise, the higher the image purity and the better the image look and feel.

So you can see the introduction of pixel size under the details page of many mobile phones. For example, the unit pixel size of Xiaomi MIX 3 is rated as 108 by DXOMARK, a professional camera evaluation agency, which reaches 1.4um, ensuring sufficient light input, which is the premise of taking good photos.

Super night scene mode-you can shoot big movies in dark environment.

In order to improve the image quality, highlight input is an indispensable prerequisite. However, the internal space of the mobile phone body is narrow, and increasing the CMOS size is contrary to the trend of increasing the integration of the mobile phone, so the CMOS size of the mobile phone cannot be increased indefinitely. Therefore, night imaging in extremely dark environment is a very big test for mobile phone cameras. However, the advantage of mobile phone lies in its strong computing power. At present, many brands have added "night scene mode" to their mobile phone cameras. Of course, their names are different, some are called "super night view", some are called "city night view" and so on, but the basic principle is the same.

Reduce the shutter time appropriately and take more photos for multi-frame synthesis. Because most mobile phone photos need to be taken manually, OIS optical image stabilization is essential to ensure stable imaging. Of course, the most test is the strength of algorithm optimization. In the industry, negative optimization is also very common.

The above is the comparison of real photos taken in automatic mode and super night mode, and the difference is very obvious. Not only the brightness of the picture is higher, the impression is better, but also more details of the picture are retained.

The night scene mode greatly improves the adaptability of the mobile phone camera to the environment, and can take high-quality photos even at night.

Ultra-wide-angle lens-wider field of vision, easy to take high-definition landscape photos.

Wide-angle lens has a wider field of vision and a stronger three-dimensional sense, which is suitable for shooting grand scenes and is often used in landscape photography. A large wide-angle camera with130,000 pixels can capture the photo field of view of Quan Huafu SLR lens over16 mm.

Wide-angle lens is characterized by "barrel distortion", which has a strong stretching effect on the sense of space and is often used to create special effects. But it is difficult for ordinary users to master, so the distortion of wide-angle lens needs special attention. Fortunately, there are already mobile phones with distortion correction function, which can make most users meet the needs of wide-angle shooting to a certain extent.

Qualcomm Snapdragon SOC provides a powerful ISP, which makes everything possible. Super wide-angle photography and super night scenes actually benefit from the improvement of ISP's computing power.

AI artificial intelligence-you can make a big movie without knowing the composition and color matching.

There is no doubt that mobile phone cameras are smarter than SLR. Although many SLR cameras also provide automatic mode, so that camera parameters can adapt to the scene, they are still much weaker than mobile phone cameras.

AI technology is quite mature at present, and it has been able to accurately identify the shooting scene and accurately analyze the objects and far and near levels in the picture. According to different scenes, the matching filter and exposure combination are automatically selected to obtain the best picture effect, so that ordinary users can easily shoot high-quality blockbusters. Simply put, it can make the blue sky more beautiful, the green plants greener, the food more attractive and the people more beautiful.

AI scene recognition is indeed a very practical photo assistant. At present, many mobile phone cameras have this function.

AI is also applied to front camera beauty. Accurately identify people's five senses, carry out personalized real-time beauty, and avoid sameness.

But for mobile phone cameras, the application scope of AI should be far more than this, and more can be discovered. For example, after accurate recognition of screen objects, accurate matting can be realized in theory, and more interesting photos can be generated through simple post-processing. The mobile phone camera after AI blessing will have more gameplay, which is worth looking forward to.

Portrait light effect-makes people look like photos with higher texture.

Apple has added portrait lighting effects to iPhone 8 Plus and iPhone X since last year, which has attracted much attention from the industry. This year, this function has been widely popularized. IPhone provides natural light, studio lighting, contour light, stage light and monochrome stage light. You can easily take high-value portrait photos.

In fact, the realization of portrait light effect is also based on the popularity of AI technology.

At present, the imaging strength of mobile phone cameras can not be underestimated, and these improvements largely depend on the improvement of ISP computing power and the popularization of AI technology. Moreover, through the camera, it can be seen that the experience of domestic mobile phones in many aspects has become more and more mature. The iPhone, which has always been the benchmark for taking photos, has been completely surpassed by brands such as Huawei and Xiaomi, and domestic brands are increasingly showing hard power.

This paper lists all the new technologies about mobile phone photography, which is of great benefit to improve the imaging quality and playability of mobile phones. If you pay great attention to taking photos with your mobile phone, you must pay attention to these points mentioned in the article when buying a mobile phone.

Based on the above and the actual experience of the product, we recommend Xiaomi MIX3 mobile phone for users who attach importance to taking photos with mobile phones. Although Xiaomi MIX3 does not support wide-angle shooting, its performance in other aspects is already one of the best mobile phones at present. The latest DXOMARK data shows that the main lens score of Xiaomi MIX3 is 103, tied for third place; The front camera scored 84 points, also ranked third.

Combined with its product price and hardware performance, the flagship Xiaomi MIX 3 is worth buying. At present, Xiaomi MIX 3 is in stock in major channels such as Xiaomi Mall, and there is no need to snap it up. The starting price is 3299 yuan.
