Google's New Google Pixel 4 And Pixel 4 XL With Radar Chip And Astrophotography

Google Pixel 4 and Pixel 4 XL


Google Pixel 4 And Pixel 4 XL:

Google sends the Pixel 4 and Pixel 4 XL into the race - with radar-based gesture control, new exposure mode for the camera and offline voice recognition.

Google has introduced the fourth generation of its Pixel Smartphones. The Pixel 4 comes in two sizes: The standard model offers a 5.7-inch display, the Pixel 4 XL is 6.3 inches in the diagonal.

A Notch does not exist in both cases, unlike its predecessor. The most important innovations are the Astro mode of the camera as well as the motion Sense mentioned gesture control, for which Google relies on the radar system Soli.

However, the new camera should cause a stir. For the first time, Google has introduced a dual camera:

one with wide-angle (77 degrees) and 12 megapixels and a telephoto lens with 16 megapixels at an opening angle of 52 degrees and a spectral and flicker sensor.

As with previous generations of pixels, the secret of the good photos is largely due to the camera app,

which either creates deceptively real bokeh effects using AI or produces quite brilliant and thus low-noise photos by means of multiple long-term exposures in so-called night mode even in low ambient light,

At Pixel 4, Google is now pushing the night mode to the top and adding an Astro mode that will also allow you to take stunning shots of the nightly starry sky with the help of several long-term exposures - at least the photos we found on the demonstrators as part of the presentation seem to confirm that.

Another feature is called Dual Exposure. If you photograph with a conventional smartphone in the backlight, for example, people in front of a sunset, you had to decide so far:

Either put the exposure on the people, which then usually led to the overexposure of the sky. If you chose a short shutter speed instead, the characters were only black silhouettes.

Dual Exposure, on the other hand, makes it possible to use two virtual sliders in the camera app to set the exposure time - ie the brightness - of the background and the main subject separately, resulting in very attractive HDR pictures.


Google Pixel 4 And Pixel 4 XL Motion Sense:


A Pixel 4 exclusive feature is Motion Sense called gesture control, which uses the radar chip soli placed at the top of the case.

Motion Sense is used for presence detection, smartphone grabbing and finger gestures.

Thus, the presence detection ensures that the display does not switch off, regardless of the set timeout, as long as the users hold the smartphone in their hands.

On the other hand, if the smartphone is lying idle on the table, the display will automatically switch on as soon as you stretch your hand to grab it.

This also activates the face recognition. In our hands-on, Pixel 4 was unlocked almost immediately when we picked it up.
Face recognition worked with just about any device orientation, using a whole sensor array of camera, soli-chip, brightness and distance sensor, two infrared cameras, a light, and a projector that throws infrared points at the user's face come.

Google seems to trust the reliability and security of the Face Unlock so much that the 4-pixel has no fingerprint sensor.

According to Google, the biometric data remains in the smartphone and does not migrate to the cloud at any time.

Last but not least, the soli chip is suitable for gesture control without having to touch the smartphone.

 So we were able to jump on a song during the presentation of the phones on Spotify and Youtube music by waving our hands over the phone.

This is a weakness of Motion Sense: Apps must explicitly support this type of operation. There is also a regional restriction.

Since the soli chip operates in the frequency range between 57 and 64 GHz, the approval of the responsible authorities is necessary. In Germany and some other countries, this was granted, but not in many others.

Offline speech recognition coming soon


The AI ​​will also help the Google Assistant leap forward: At this year's Google I / O, Google boss Sundar Pichai announced that advances in deep learning are making it possible to reduce the approximately 100 GB AI model to half a gigabyte reduce so that it now fits on phones.

In practice, this means that the Google Assistant on Pixel 4 phones does not require an Internet connection for speech recognition.

This not only brings more data protection but also ensures a noticeably faster response time of the digital assistant.

Simple commands, such as the launch of the desired app, led the Assistant in our tests almost without delay.

In addition, offline detection allows a function that could be described as a search in audio files. Already with the first leaks to the Pixel 4, the question came up, what it has with the preinstalled audio recorder app on itself.

The puzzle solution: The recorder automatically transcribes the audio recordings, so that afterwards a full-text search is available,

with which one can jump in the reproduction to the place searched. In the future, the recorder should even be able to distinguish between several speakers.

But unfortunately the thing has a catch: So far, the new Assistant and its offline speech recognition is only available for English.

The German-language model has not yet been evaporated and shipped to cell phones. But Google wants to make up for that next year.

Speaking of catching up: Many new software functions of the Pixel 4 wants to bring Google also on older models.

With little patience owners of a Pixel 2 or Pixel, 3 may look forward to the new assistant or the Astro mode of the camera.
