Samsung introduces an ultra-high resolution 64MP image sensor for smartphones

High-resolution camera sensors are becoming the craze in the smartphone market right now.

This year, we are seeing high resolution cameras become more and more popular in the smartphone market. Samsung, however, uses a remosaic algorithm to interpret more information for the full field. Now, Samsung is stepping up the camera game with its new ISOCELL Bright GW1 image sensor that brings 64-megapixel resolution. Because small pixels can capture less light, this usually results in higher image noise. Samsung realizes this and is pushing the envelope with its new 64-megapixel image sensor.

Samsung ISOCELL Bright GW1 is a 0.8-micrometer (?m) pixel 64-megapixel (Mp) sensor. Tetracell enables 4-in-1 pixel binning that merges four pixels into a single pixel to mitigate the pixel size deficit in challenging light situations.

Google said the most important goal with the redesign was to show more useful information with a quick glance at the screen. The idea with the technical preview is to get early adopters to try it out and provide more feedback.

It also supports real-time high dynamic range (HDR) of up to 100-decibels (dB) that provides richer hues. According to the company, the sensor also able to deliver bright 16MP output during low-light conditions with the help of its Tetracell pixel-merging technology. The company has asserted that the dynamic range of a conventional image sensor is somewhere near 60dB. No word yet on when we'll begin to see it in smartphones, but Samsung presumably has plans to feature the technology in its own Galaxy line of devices.

The sensors also feature Dual Conversion Gain, which allows the sensor to take in light information in bright conditions up to its saturation point. This is said to allow the sensor to optimize its full well capacity (FWC) by using collected light more efficiently especially in bright settings. Both the seensors - GW1 and GM2 come with support for Super PD which is a high-performance phase detection auto-focus technology. The GM2 also makes use of DCG for better performance and Super PD for fast autofocus just like the GW1.
