At the Rice Noodles Festival, a new product, Michaelis Panoramic Camera, was launched incidentally. This product is very similar to the 360 degree panoramic camera that many manufacturers have launched last year. As the first equipment of Xiaomi in this market, what is the difference of Michaelis Panoramic Camera?

Packaging and Design

On the outer package, Mijia panoramic camera adopts the current common pure white main color. The machine rendered image is printed on the front, and the real object can be seen after opening. Compared with the rendered image on the outside, the real object appears more refined and textured.

First, let's take a look at the accessories. There are small brackets, San Bao instructions, data cables and camera protective covers. It's a pity that there is no charger.

The Mijia panoramic camera is like a small rectangular box, with smooth transitions on the four corners. There are very "prominent" lenses in the center of the front and back. The factory has a plastic protective film, a ring of metal wire drawing decoration around the lens, and the indicator light is also hidden in it. Although plastic material is used, the texture of the whole machine is good with skin like treatment and moderate metal decoration.

All the key interfaces are arranged on the metal middle frame. According to the official introduction, it is made of a whole piece of aluminum alloy. The surface is also sandblasted, which improves the grade. There is a power key, Wi Fi switch and record button on the top. After the power is turned on, the power key also acts as a function switch button.

Of course, the key point at the bottom is the bracket interface, which is convenient for users to fix in different places or take photos by hand. The metal contact next to the interface can be used for charging. However, there is no corresponding charger attached, and users need to purchase it by themselves.

Because waterproof treatment is required, the microSD card and USB interface are equipped with dust-proof covers. IP67 level protection ensures normal use in harsh environments.

The built-in small bracket can be folded, which is convenient for use in different scenarios. Users can hold it or place it fixedly.

Immature app

Similar to other manufacturers, Mijia panoramic camera also needs an app, but unlike previous Mijia products, which are all integrated in the same app, this time a separate application called "Mijia panoramic camera" has been launched. The main interface of the app is Mijia's discovery that it is somewhat similar to Instagram's image social networking, and only by clicking the camera button can we enter the shooting process. It seems that Mijia's recollection is not just a panoramic camera, but now it can only view the official account, which is not fully open.

The shooting interface is similar to that of an ordinary smart phone. It is specially reminded that the microSD card must be of Class10 or above, otherwise the machine will not work properly. The official recommendation is to use the U3 specification. However, as mentioned in the subtitle, the app is not mature. It is not uncommon for the real-time preview interface to get stuck. Occasionally, the preview interface has not been refreshed after waiting for a long time. I hope it can be solved in the later upgrade.

Mijia panoramic camera uses Sony IMX206 (the same model as the original Xiaomi mobile phone) on CMOS, and video shooting is supported at the highest level 3456x1728@30fps Specifications: the photo resolution is 6912x3456. It supports manual setting of shutter time and ISO. The shutter time can be up to 32s and ISO can be up to 1600. These parameters are excellent in panoramic cameras. When viewing photos, you can select a variety of display methods, or automatically change with the status of the mobile phone gyroscope, which is interesting.

Actual performance

It is known whether it is a donkey or a horse, so it is better to talk about the strength of Mijia panoramic camera with proof. Open it with a general picture viewing software, and the sample will show a 180 degree picture, and some traces of stitching can be seen. The scene near the stitching can be seen to be greatly affected, which is prone to deformation and blurring. When magnified to 100%, the scene similar to other panoramic cameras in the middle and long distance is easy to blur, but the clarity in the far and near is good, ignoring the traces of splicing, and the overall white balance is OK.

Such a picture is a typical example. The two cameras of Mijia panoramic camera are prone to a large metering gap, which is not harmonious after splicing. In addition, the sharp decline in the image quality of the wide-angle lens edge will be magnified here, and the objects at the edge are easy to blur.

If the light conditions are good and the two cameras are close to each other, the performance of the proof is very good. The details of the proof and the white balance can compete among many panoramic cameras. If the research and development team can further strengthen the splicing algorithm and light measurement, the performance of Mijia panoramic camera is worth looking forward to.

The proof in the night scene looks a little worse than that in the daytime, mainly because the anti glare ability of the lens is weak, which makes the "light pollution" more obvious. The noise control is acceptable if you don't take a closer look at it, and the stitching traces at night are better handled than the daytime samples.

When shooting at night, the big problem lies in the white balance. Shoot three pictures in a row at the same place, and the gap between the white balance is visible to the naked eye. Because this problem cannot be seen on the preview interface, it is recommended to take more pictures in the weak light environment and select the satisfactory ones.

The white balance problem that easily occurs in low light environment can also occur in shooting videos. However, because domestic video websites are not very compatible with panoramic videos, friends in need may have to use YouTube to solve the sharing problem.

Finally, there are two points to be noted. In terms of endurance, the Wi Fi real-time preview is enabled in the whole process of actual use, and about 20 photos are taken, which takes about 2 hours and consumes about 50% of the power. This level is similar to that of previously tested panoramic cameras; Heating is still the weak point of the panoramic camera. After taking a few photos, the body becomes hot. This situation not only appears in Mijia, but also in other manufacturers. We can only wait for more efficient hardware solutions.

The performance of Mijia panoramic camera in hardware can be said to be quite excellent - both texture, workmanship and design are the best in the current panoramic camera, and the heating problem caused by hardware limitations should be eliminated (After all, everyone is hot) Michaelis Panoramic Camera is really worth considering as an entry experience product if the R&D team can improve its immature app, stitching trace and shooting algorithm that need to be improved in future updates.
