Samsung has launched two new 0.8-μm picture sensors to be used in upcoming smartphones. The new sensors are the 48 MP ISOCELL Bright GM2 for superior handsets in addition to the 64 MP ISOCELL Bright GW1 for flagship telephones. Both 0.8-μm picture sensors not solely characteristic very excessive resolutions by way of use of very small pixels, however they help quite a lot of applied sciences designed to enhance picture high quality.
Samsung’s new flagship 64 MP ISOCELL Bright GW1 0.Eight μm picture sensor options the trade’s smallest pixel for present smartphone sensors. It additionally helps the corporate’s 2×2 pixel-binning Tetracell know-how, which merges 4 pixels into one to supply brilliant 16 MP pictures. The know-how explains that the sensor color filters are literally organized in a 4×4 subpixel association, which means chroma decision is at a local 16MP. Samsung nonetheless additionally is ready to help a re-mosaic algorithm to make full 64MP decision pictures in brilliant circumstances. Other options of the GW1 embody Dual Conversion Gain (DCG) that optimizes its full nicely capability (FWC) in well-lit environments, and speedy Super PD part detection auto-focus know-how.
The GW1 additionally helps a real-time dynamic vary of as much as 100 dB. Just to place the quantity in context, the human eye can distinguish hues of round 120 dB (based on Samsung), whereas current-generation sensors are all beneath this and have a tendency to have extremely diverse dynamic ranges. (Samsung for its half places the trade common at 60 dB, although this appears a bit low for high-end sensors)
Meanwhile the 48 MP ISOCELL Bright GM2 sensor has the identical characteristic set because the GW1 (Tetracell, re-mosaic, DCG, and Super PC), however makes use of a smaller half of” sensor, versus the much larger 1/1.72″ GW1.
The GW1’s giant sensor dimension equals that of Huawei’s 40MP sensors designed by Sony. Here an enormous compromise of the massive dimension is that distributors would both should drop OIS or implement designs with bigger digital camera bumps with a purpose to accomodate the larger optics required for the massive sensor.
Samsung is sampling its ISOCELL Bright GW1 and GM2 with clients and plans to mass produce them within the second half of the yr.
