Samsung introduces 48- and 32-megapixel sensor




for smartphone cameras
Samsung has presented the Isocell Bright GM1 and GD1. These are two smartphone camera sensors with resolutions of 48 and 32 megapixels respectively and pixels with a size of 0.8 microns.

Samung does not say which format the sensors have exactly, but says that there is now a lot of demand for very small image sensors with high resolution. The two sensors have a relatively small pixel size of 0.8μm, which according to Samsung allows smartphone manufacturers to integrate smaller modules in their phones or to include more pixels in existing designs. The South Korean manufacturer says that with GM1 and GD1 the space in contemporary smartphones with small bezels is limited.

Based on Samsung’s so-called Tetracell technology, the GM1 and GD1 can work together and merge four pixels to act as a single pixel. This would correspond to the light sensitivity of a 12- and 8-megapixel sensor respectively with 1.6μm pixels. Both sensors support gyro-electronic image stabilization and the GD1 also has support for high dynamic range functionality; this is missing at the GM1.

Samsung says it expects the Isocell GM1 and GD1 to take mass production from the fourth quarter of this year. It is not yet clear when telephones with both sensors come out. For the time being, most smartphone manufacturers use IMX sensors from Sony. This Japanese company also announced in July a new 48-megapixel sensor with pixels of 0.8μm, namely the IMX586 . This must increase the light sensitivity by means of an adapted Quad Bayer filter.
