Samsung has introduced a 48-Megapixel and 32-Megapixel image sensors
Samsung has prepared two new products: 48-Megapixel and 32-Megapixel image sensors ISOCELL Bright GM1 and 32Mp ISOCELL Bright GD1. Each of the sensors contains an array of the smallest photodiodes in the industry, the step of which is 0.8 microns. Actually, otherwise the sensors would be very large and we would hardly see them in smartphones. To release a sub-micron image sensors, the company approached in 2015. Then an image sensor with 1 µm pixels was released, and a year ago the company began to supply sensors with 0.9 µm pixels.
Both sensors are issued using the technology of isolation of the adjacent pixels (photodiodes) from the mutual influence or the pixel isolation technology (ISOCELL Plus). In addition, each sensor also supports Samsung's proprietary Tetracell technology. The downside of pixel size reduction is the reduction in sensitivity of each individual photodiode. Tetracell technology allows four adjacent pixels to work as one. With regard to sensors GM1 and GD1, such as light sensitivity mode Tetracell equivalent pixels with a pitch of 1.6 µm. However, the number of effective pixels will be reduced to 12 and 8 MP, respectively.
Finally, the GD1 sensor differs from the GM1 sensor in that it supports real-time dynamic range expansion or HDR. This will allow for a more balanced exposure even in low-light shooting conditions or in the case of very contrasting scenes with bright light and shadows. HDR also ensures richer colors and greater detail in both static photos and video recording. The company will start production of new sensors in the current quarter. We are waiting for new products in smartphones of 2019.
