The reason why Google Pixel takes better photos than iPhone


Google Pixel 3a loyal to a single camera, but no one dared to doubt the image quality of this device.

Smartphones have gone beyond and completely captured the dominant position in the low-end camera market in the past 10 years. Although they cannot compete with DSLRs with large sensors or mirrorless devices with high-end imaging, smartphones are easy to use, easy to connect and convenient to the point that almost everyone Have a compact camera in your pocket wherever you are.

And in the hundreds of thousands of smart phones on the market, not all of a sudden, the online community as well as technology experts, photographers … must constantly admire and admire Google with the camera system. This manufacturer is equipped with Pixel smartphones.

Google Pixel can produce images that exceed the resolution of the sensor on the device.

Recently, Google unveiled the secret behind this technology, which made Pixel an impressive photography tool, despite the fact that they only own a 12.2 megapixel camera system. It can even produce images with superior quality than those with 3 or 4 separate cameras specialized to handle different shooting conditions, devices with 3D sensors that measure depth or depth. Products with expensive lenses have wide apertures.

The difference in photos from Google Pixel is most evident in shooting in low-light Night Vision and Super-Res Zoom modes, which allows you to zoom in and capture clear images in excess of the pixel count. image sensor.

The key to the problem lies in continuous shooting, which happens to most Pixel shots whether or not users require it. When pressing the shutter button, the camera will capture a series of frames at the same time. This, in addition to image processing algorithms, allows you to basically never have to worry about whether the subject you want to capture is closing your eyes. The phone will sort through several dozen frames and simply select what it thinks is when the subject has the widest eyes and the brightest smile. This makes you feel like a "qualified" photographer.

On the left is how Google Pixel reduces the moire effect in the image, to the right is how the system reproduces small details in a high-resolution image.

But not yet, Google Pixel software also makes the photos more interesting. This system will get clear details in single frames to create a super high resolution image. This is similar to the way the Panasonic S1R high-end model does, but uses the hand shake state itself instead of the sensor system.

Simply put, the phone will take a few pictures from the machine when the user's hands are shaking unsteadily, then put them together. Next, the system will check the motion in the frame, things that are actually moving are not the result of the device shaking. This allows it to create a map of motion, find out which part of the image it can enhance the resolution and somewhat impossible.

Then, in the parts of this controlled image, it overlaps the moving images nicely by combining frames. The more frames are combined, the more clear the details, even beyond the normal resolution. Even, the software can use this information, along with its own algorithms to calculate angles, small areas of detail to give an image of what is happening. From there, it builds a detailed and clear overall picture when users use the Super-Res Zoom feature.

Compare images between Google's processing algorithms and other processes.

With the technique of collecting information on multiple frames with slight deviation, Google Pixel also draws out the amount of information about color and contrast, thereby creating impressive images in low light shooting conditions. Night Vision mode. It helps control noise and suppresses noise extremely well, as well as eliminating the moire effect (images are applied in multiple colors when shooting products with many stripes and nets like when shooting objects with leather, fabric …) and chromatic aberration, Bleed effect (color overflow in transition zone clearly between dark and bright).
