The newly released Dajiang Osmo 360 uses two 1/1.1 square sensors, which have exceeded the specifications of all sports cameras on sale.
At this time, many Yanzu would be curious: Can you use a panoramic camera instead of a sports camera? Can we win the sports camera?
After all, Dajiang Osmo 360 with two lenses only costs 2999 yuan (if you have a national subsidy in your region, the price is 2549 yuan), while the Action 5 Pro with a single lens costs 2598 yuan (2208 yuan after the national subsidy). The price difference between 3 yuan and 400 yuan is that there is an extra lens, a larger sensor and a lot of playing methods.
But here we can Save flow in advance: no, it can't be reached.
Here are some popular science about panoramic cameras. For interested Yanzu, you can order a cup of cappuccino and take a look.
Principle of panoramic camera
A panoramic camera is a 360 degree field of view combined by two fisheye lenses ↑↓ with a field of view of more than 180 degrees.
The actual imaging area is only the circle ↑ in the center of the sensor.
Disassemble Jerry's shadow stone X5 ↓ (strawberry flavor silicone grease) (periscope set is used) ↓
Surprise! The periscope telephoto listens much, but I didn't expect that the fish eye ultra wide-angle lens can also use the periscope structure.
In order to reduce the thickness and facilitate panoramic synthesis, panoramic cameras have always been periscopic fisheye ultra wide angle lenses (the thinner the body, the smaller the blind angle of panoramic synthesis field of vision, the smaller the required fisheye lens angle, and the better the detail performance).

According to official information, Dajiang Panoramic Camera is planned to be established in 2022. The square sensor preliminary verification+prototype will be completed in 2023, and the components will be verified+delivered in 2024. In fact, Dajiang Osmo 360 has passed the FCC certification in October 24 ↑.
This Howell sensor of unknown model is 1/1.1 type, with square 64 million pixels, 8000x8000, 1.2 μ m (2.4 μ m for daily use, and 16 million pixels for 4000x4000 output). Maximum 13.5 gear dynamic range, Quad Bayer arrangement, non 2x2 OCL (good civilization!!!!! ), physical size 9.6 x 9.6 mm (12.8 x 9.6 mm for 4:3 inches).
this The 64 million pixel high pixel big bottom scheme, not to mention panoramic cameras and sports cameras, is it OK for flagship phones to want it? (For mobile phones, whether it is the 1-inch Sony LYT-900 or the 200 million pixel Samsung sensor, the number of physical microlenses is still 50 million pixels, all of which are details of 50 million pixels).
1/1.1 type square sensor
In the field of sports cameras, the last customized sensor is the 1/1.9 type 8:7 sensor of GoPro in 2022 (from Hero 11 to Hero 13 now): 27.6 million pixels, 5599x4927, and 16:9 video with a maximum of 5.3K 60fps, which is essentially the longitudinal filling of the original 1/2 type 23.6 million pixel sensor.
Sports cameras/panoramic cameras/UAVs are generally sensors that pick up "leftovers" in the mobile phone supply chain, This can significantly reduce costs.
However, the needs of mobile phones and sports cameras/panoramic cameras are different:
For focusing, dark light enhancement and cost control, mobile phone sensors are mostly of 2x2 OCL micro lens structure (sacrificing detail performance, changing focus and dark light performance);
However, the motion camera/panoramic camera is a pan focus lens that does not need focusing, and it will be very difficult to use 2x2 OCL.
The 1/1.1 square sensor of Dajiang Osmo 360 actually cuts off 1/3 of the area on both sides of the 1 inch 4:3 sensor ↑. This is why Dajiang said that "the imaging area is the same as the 1-inch sensor with 4:3".
PS: If the area of Dajiang Osmo 360 is 9 (3x3), the traditional 4:3 sensor is 12 (4x3), and the imaging circle area is 1.5x1.5x3.14=7.07 → the sensor utilization of Dajiang Osmo 360 is 79% (7.07/9), and the utilization of 4:3 sensor is 59% (7.07/12).
If and 1/1.28 type Compared with the shadow stone X5, the provincial current is that the sensor area of Dajiang Osmo 360 is only 23% larger, but the actual imaging area is 64% larger, and the aperture is also larger.
The 33% of the area that the panoramic camera will never use is paid, consumed, and heated, but it does not participate in the imaging (that's sad). Dajiang, a customized square sensor, is beneficial without harm (the only cost is to customize it, and you need to pay more).
The cost of square sensor decreases ↓, power consumption decreases ↓, and heating decreases ↓.
Correspondingly, the volume of the lens and the body decreases ↓ and the weight decreases ↓ (when the shadow stone of the 1-inch panoramic camera ONE RS did not completely cover the sensor, the body weight was 239 grams).
Officially disclosed Sensor cost, from high to low (Both machines can change the outer lens, 159 yuan and 199 yuan respectively):
1/1.1 type of two squares>1 inch of 4:3>1/1.1 type of square (Dajiang Osmo 360 single)>1/1.28 type (LYT-818).
In fact, it can also be verified from the maintenance price ↓, the single lens maintenance price of Dajiang Osmo 360 is 679 yuan (sensor+lens set), and the single lens of Shadow Stone X5 is 619 yuan (also sensor+lens set). The maintenance price of 1-inch mobile phone is between 900 and 1200 yuan.
Dajiang, a master of supply chain management, will definitely reuse this sensor in as many models as possible.
We guessed, and then It is most likely to use the 1/1.1 square sensor , should be Dajiang Action 6 Pro motion camera, Dajiang Neo 2 and Flip 2 UAVs.
The sensor has high pixels and is not 2x2 OCL, so it will have better details. The square ratio is convenient for cutting into horizontal and vertical pictures, and it is also suitable for electronic anti shake.
Dajiang said, This Haowei sensor is monopolized by Dajiang this year, but it is hard to say next year.
Comparison of actual usable area
The science popularization is almost enough, and hard dishes can be served.
One picture, one sentence can finish ↓:
When the sensor area is the same, the panoramic camera needs to accommodate several times the scenery of the motion camera (the panoramic camera needs to be turned on for 8K to catch up with the 4K of the motion camera) 。
Dajiang Osmo 360, sensor, imaging circle, coverage area of each mode ↑
The imaging area of 1/1.3 type motion cameras such as Dajiang Action 5 Pro is the same as the single lens extremely wide-angle mode of Dajiang Osmo 360 (see the area with the most dense text in the picture).
The motion camera (Action 5 Pro) has a 155 degree field of view, and the panoramic camera (Osmo 360) has a 170 degree field of view, which is just close to the field of view of Action 5 Pro equipped with an amplifier.
Comparison of all data ↓
Focusing on the topic, Yanzu may find that the four corners of the single lens 4K extreme wide-angle mode have exceeded the coverage area of the fisheye lens (pay attention to the four corners) ↑. The information of those four corners depends on the extension of the corners of the fisheye lens (another debuff).
In addition to perceptual cognition, data cognition ↓
The actual usable pixel area of Dajiang Osmo 360, In fact, it is close to the OV48C of 1/1.32 model (48 million pixels), with 47.27 million pixels available (70% more than Shadowstone X5)
and Shadow stone X5, the actual usable pixel area, is slightly larger than 1/1.73 IMX686/IMX600, and the usable pixels are 27.81 million pixels.
In addition to size differences, there are also differences in HDR of on-chip hardware:
The 8K (2x3840 × 3840=7680 × 3840 for front and rear dual photography) and most modes of Dajiang Osmo 360 are 2.4 μ m pixel 4-in-1 mode, which can play 13.5 gear HDR dynamic range;
The LYT-818 of Shadow Stone X5 has only 3072 pixels on the short side after the pixels are 4 in 1, so only the 5.7K mode (2x2880x2880 for front and rear dual photography) is 2.4 μ m, which can play the dynamic range of 13.5 gears.
The 8K video of Shadowstone is actually generated in the state of 1.22 μ m (at this time, the short side has 6144 pixels). At this time, there is no dynamic range of 13.5 blocks.
However, the shadow stone is over mined from 11K (11904x5952=5952x5952x2) to 8K (7680 × 3840), so as long as the light is enough, it will theoretically have stronger detail performance (in fact, Dajiang should also be able to do over mining, but the current firmware does not).
