Samsung has introduced two new 0.8 μm image sensors for future smartphones. The new sensors are the 482 ISOCELL Bright GM2 for advanced handsets and the 64 Gx1 ISOCELL Bright GW1 for flagship phones. The two 0.8 μm image sensors offer not only a very high resolution through the use of very small pixels, but they support a number of technologies designed to improve the quality of the image. 39; image.
Samsung's new ISOCELL 64 MP Bright GW1 0.8 μm flagship image sensor features the smallest pixel on the market for today's smartphone sensors. It also supports the company's 2×2 pixel Tetracell technology, which merges four pixels into one to produce 16 MP light photos. The technology explains that the color filters of the sensors are actually arranged in 4×4, which means that the chrominance resolution is 16 MP native. However, Samsung is also able to support a re-mosaic algorithm to create images with up to 64MP resolution in bright conditions. Other features of the GW1 include Dual Conversion Gain (DCG), which optimizes wellwell (FWC) capability in well-lit environments and fast Super PD phase-detection autofocus technology.
The GW1 also supports a real-time dynamic range of up to 100 dB. To put the numbers in context, the human eye can distinguish tints of about 120 dB (according to Samsung), while the sensors of the current generation are all below this range and tend to have dynamic ranges very varied. (Samsung, for its part, puts the industry average at 60 dB, although that sounds a bit low for high-end sensors)
Meanwhile, the 48 MP ISOCELL Bright GM2 sensor has the same features as the GW1 (Tetracell, re-mosaic, DCG and Super PC), but uses a smaller 1/2 "sensor, compared to the much larger GW1 1 / 1.72 ".
The large size of the GW1 sensor is equal to that of the Huawei 40MP sensors designed by Sony. Here, a big compromise of the big size is that the providers should either abandon the OIS, or implement designs with larger camera bumps in order to accommodate the larger optics required for the larger sensor.
Samsung is currently testing its ISOCELL Bright GW1 and GM2 with its customers and plans to mass-produce them in the second half of the year.
