New Samsung 20MP image sensor is the world's smallest

Like the increasingly common 48MP sensors found throughout the smartphone landscape, Samsungs new 64MP shooter will employ the Tetracell binding technology. Phone manufacturers have contentiously upped the ante in the past years and Samsung is looking to bring the latest breakthrough in mobile photography with its 64MP ISOCELL Bright GW1 sensor.

With such a compact form factor, the sensor can reduce the height of Samsung's tele-camera module by around seven percent. However, with the advent of effective 4-in-1 pixel binning, cameras can deliver high resolution photos in daylight, and pixel binned lower resolution photos in low light that benefit from better noise reduction, dynamic range, and per-pixel detail. Introduced last October, Tetracell can be used to merge four pixels into one larger pixel to capture more light detail in hard conditions.

He amassed a 128-83 record with the Cavs and won two previous titles as a reserve with the Lakers in '00 and '01. The Lakers are looking to replace Luke Walton, who was sacked after three seasons with the team.

The new ISOCELL Bright GW1 sensor beats Samsung's and Sony's 48 megapixel IMX586 in terms of pixel count but, but that is about all the differences, as the three have something in common, albeit different names and more pixel counts. That's partly due to the excellent imaging sensors Samsung uses in their devices. As a result, you are able to get bright 16MP images in low light and highly-detailed 64MP shots in brighter situations. Samsung claims that its new sensor has an HDR of "up to 100 decibels" while the human eye is rated at 120dB. "This allows the sensor to optimize its full well capacity (FWC), utilizing the collected light more efficiently especially in bright environments", Samsung said on its website. Samsung has also packed other tech into GW1 including Dual Conversion Gain (DGC), Super PD auto-focus technology, and the support for full HD 480fps slow-mo video recording.
