The competition of global brands in action photography is becoming more and more fierce, and the development of related black technology is even more dizzying. Oppo, which continues to deliver many amazing shooting effects and feature phones, also announced their upcoming breakthroughs in black technology for mobile photography at the recent future imaging technology conference. In addition to the part that focuses on improving related technologies, it also includes what I am looking forward to. For the breakthrough of the “continuous” optical zoom capability of the telescopic periscope lens, the anti-shake achieved by the combination of the lens and the photosensitive element anti-shake is officially pushed to the mobile phone. The specifications of the field. Continue to read Oppo’s future imaging technology conference. Imaging Black Technology has issued four reports in a row.

Oppo’s image black technology is released in four bursts: continuous zoom breakthrough of periscope and (total) five-axis anti-shake also appear on mobile phones
At the Oppo Future Imaging Technology Conference, they announced that there will be new RGBW sensor technology used in products as early as the fourth quarter. Through the self-developed four-in-one pixel polymerization technology and DTI pixel isolation technology, Oppo not only can effectively avoid the moiré problem, but also can obtain 60% higher light input than before with the newly arranged RGBW sensor. At the same time, it reduces noise by 35%.
Technological breakthroughs that also tend to improve the existing imaging technology are also the next-generation off-screen lens technology that uses innovative screen pixel arrangements and can improve diffraction and blurring through software algorithms. While maintaining a pixel density of 400ppi and a screen brightness difference of less than 2%, the AI smart image algorithm can bring more natural HDR and automatic white balance shooting effects.
The last two of the four consecutive releases of image black technology, one is the five-axis anti-shake specification confirmed to be released in the first quarter of next year, and the other is the “continuous zoom” technology that breaks through the existing periscope limitations. The former is actually very common in many existing professional cameras, but Oppo’s five-axis lens shake-proof and photosensitive element shake-proof structure does not seem to see the two-axis of YAW and PITCH?
According to the information obtained by foreign media, Oppe’s so-called five-axis anti-shock technology is actually to first activate the X and Y-axis anti-shake on the lens module when a small vibration is detected; when the sensor detects a larger vibration, It will activate the additional anti-vibration of the photosensitive element added to the Roll rotation axis to correspond. So in terms of the direction of anti-vibration, there should be only three axes, but since it is labeled “coordinated anti-vibration”, maybe it will be added up and labeled as five axes (right). It can also be assumed that this system uses a hybrid optical anti-shake system that can strengthen each other’s stability. Of course, the detailed operation logic and technical details may have to wait for actual mass production or display to confirm.
According to official information, although this anti-vibration system does not indicate the effect with the compensation levels commonly used in camera products, it is mentioned that it can achieve 65% compensation under the performance of plus or minus 3 degrees of anti-vibration compensation and 3.5 times compensation accuracy. Improved performance has increased the success rate of low-light shooting by 70%.
The last item is the technology of officially turning the periscope lens into a “true zoom lens” through 2 pieces of aspherical glass and a long-stroke guide shaft motor. According to the official statement, in addition to providing optical anti-shake, this technology will achieve a continuous optical zoom effect equivalent to 85mm to 200mm in terms of focal length. It is no longer the need for mobile phone lenses to switch between each other and use digital zoom to achieve continuous zooming requirements. It is really more like a normal single-eye lens or DC zoom method.
