photography on smartphones – Geekcomparison

OPPO unveiled on the occasion of the event dedicated to photography OPPO Future Image Technology 2021numerous innovations in smartphone imaging, with a strong focus on sensor updates, modules and algorithms. Let’s look at them briefly.

Next Generation RGBW Sensor

The new sensor improves light sensitivity by introducing additional white (W) sub-pixels, DTI technology and the 4-in-1 pixel algorithm developed by OPPO. This allows you to collect 60% more light with the sensor than the previous one and achieve a noise reduction of 35%.

The patented 4-in-1 pixel algorithm helps improve color performance by avoiding problems such as color inaccuracy and moiré.

In addition to improving low-light shooting, the new-generation RGBW sensor can deliver more expressive portraits, both in stills and video, in terms of texture and contrast. This new sensor will be launched in OPPO devices from the fourth quarter of 2021.

Continuous optical zoom 85-200mm

The new 85-200mm continuous optical zoom redesigns the structural module at the hardware level:

  • It first adopts G+P lens technology (glass and plastic) and introduces two ultra-thin and high-precision aspherical glass lenses to greatly enhance the optical effects, such as minimizing distant light.
  • The innovative application of a tunnel magnetoresistance sensor (TMR sensor) allows the lenses in the camera module to move with greater stability and precision.
  • The newly updated drive motor increases the dynamic tilt that allows the lens system to be moved, easily supporting continuous optical zoom at higher magnifications.

5-axis OIS

Under the news too the five-axis OIS, which allows the system processor to receive motion data from the gyroscope, analyze it and break it down through the various algorithms. This data is then passed to the two moving components: the lens and the image sensor, driven by ball motors and shape memory alloys, respectively.

When the movement is relatively small, images are mainly stabilized by OIS lens shift – which covers horizontal (X) and vertical (Y) shift. However, when the motion amplitude is relatively large, OIS with sensor shift – including horizontal displacement (X), vertical displacement (Y) and rotation – will also be used in conjunction with algorithm compensation, to achieve five-axis stabilization of space.

Camera under the screen

Finally, OPPO presented its solution of camera under the screen next generation† The innovative pixel geometry ensures a high quality display with 400 PPI in the camera area below the screen. By using transparent wiring and a new design, the result is a more refined display quality, along with a smoother viewing experience. With each pixel circuit driving only 1 pixel (“1 on 1”) in the screen and OPPO’s precise algorithmic compensation technology, the color quality and brightness of the whole screen are controlled more precisely, with a deviation of only about 2% and an improved screen life of up to 50%.
