Sony teases its next-generation Quad-Bayer smartphone sensor

09 Nov

The people at Sony’s image sensor division have posted a teaser video for an upcoming new smartphone image sensor, the IMX686, on the Chinese social media site Weibo. The new chip is the successor to the IMX586, which was one of the first 48MP Quad-Bayer sensors and has been deployed in several high-end smartphones.

Sony does not reveal the sensor resolution or other specifications in the video but based on rumors about phones that will supposedly use the sensor GSM Arena estimates it to be between 60 and 64MP.

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_5978174378″,”galleryId”:”5978174378″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

The video reveals that the new sensor will be released in 2020 and shows a selection of still images captured in a variety of light conditions. The images are not full size, so it’s hard to make any judgements about image detail or noise, but they do look quite impressive in terms of exposure and dynamic range.

Given no phone is using the new sensor yet, Sony has used a prototype board connected to a computer to capture the samples. Have a look at the gallery above and check out the full video over on Weibo.

A sample image from Samsung’s 64MP Quad-Bayer sensor has appeared online

25 Jun

In May, Samsung launched its 64MP Tetracell image sensor for use in smartphone cameras. Like the 48MP Sony equivalent that’s already inside several current flagship devices, the Isocell Bright GW1 is designed to produce full-resolution output in good light conditions and use its Tetracell technology to combine four pixels into one, for better detail, lower noise levels and increased dynamic range, in more challenging circumstances.

Like Sony’s Quad Bayer technology, Tetracell appears to duplicate the Bayer color filter pattern over groups of four pixels at a time, making it easy to combine their data for a lower-resolution, lower-noise image. On a device equipped with the Samsung sensor, this would result in 16MP images vs. 12MP files from the Sony sensor.

Samsung has even come up with the name ‘re-mosaic algorithm’ for the process of reconstructing a full-resolution image in well-lit conditions.

Now we are seeing the first sample image captured with the new Samsung sensor:

According to mobile industry ‘leaker’ Ice Universe, the 64MP sensor will not only be available in Samsung phones. This first sample image was captured by an unreleased Realme device, according to the tweet. Budget smartphone manufacturer Redmi (a sub-brand of Xiaomi) is also interested in the sensor, according to the same Tweet.

A higher-resolution version (4096 x 3072px) of the image has also been shared (h/t eno2). We are looking forward to testing the first production devices with the Samsung Isocell Bright GW1 sensor and comparing its image output against the Sony-equipped high-end rivals.

Update (June 24, 2019): Added a link to a higher-resolution version of the image.

Redmi 7 smartphone offers Sony 48MP Quad-Bayer sensor at budget price point

10 Jan

We’ve seen Sony’s IMX586 1/2-inch 48MP sensor appear in several higher-end devices in recent months but the Redmi 7 is now the first budget device to offer the chip. The sensor isn’t really meant for outputting medium-format image resolution image files. Instead a quad-Bayer filter array allows for high-quality 12MP images with low noise levels and real-time HDR processing. The main chip is accompanied by a 5MP depth sensor for bokeh and similar effects.

Redmi, which used to be the budget line within the Xiaomi smartphone portfolio, has now been promoted to a proper sub-brand, similar to what Honor is to Xiaomi competitor Huawei. The 7 is the first device launched under this new sub-brand and does not only offer impressively looking main camera specs for the money.

You also get a 13 MP front camera, 6.3-inch Full-HD+ LCD display, Snapdragon 660 chipset a massive 4,000 mAh battery with quick charge support and a microSD slot.

In terms of RAM and storage you can choose between 3/32 GB, 4/64 GB, and 6/64 GB combinations. and there is a microSD slot as well.

The cheapest option will set you back $ 150 (CNY999) and even the largest memory version is only $ 210 (CNY1,399). Pre-orders have already started in China and shipments are scheduled for January 15. We’d expect the Redmi 7 to make the jump into the US and other regions in the nearer future. We’ll have to wait for the first samples but it looks like the Redmi 7 should be high up the list of those who want good smartphone image quality at budget pricing in 2019.

Xperia XZ3 likely to come with Sony’s new 48MP Quad-Bayer sensor

27 Jul

Only a few days ago Sony announced its latest smartphone sensor, a 1/2″ stacked 48MP beast with Quad-Bayer design for improved low light performance at 12MP output size. And if rumors turn out to be true, we won’t have to wait long before the chip is available in a production smartphone.

Renders of the upcoming Sony Xperia XZ3 flagship smartphone that are floating around the internet show the new device with just one rear camera, as distinct from the dual-camera setup used by the Xperia XZ2 Premium.

This one-camera design has been confirmed by a benchmark listing, showing only one rear camera sensor with a 47MP output size. As those benchmark listings are created using pre-production models some of the specifications could still change before the launch but it’s highly likely we are looking at Sony’s new IMX586 sensor here.

We’ll know more on August 30 when the Xperia XZ3 will be officially launched at IFA and we’re looking forward to evaluating camera performance when the device is available for testing.
