Samsung has expanded its 0.8-micrometer (μm) image sensor lineup in order to accommodate the new 64MP ISOCELL Bright GW1 sensor and also the 48MP ISOCELL Bright GM2 for vibrant ultra-high resolution mobile photography.
Samsung is well-known for its products that offer great digital photography and the credit for this quality goes to imaging sensors that the company uses. Samsung makes use of these imaging sensors for its own devices and also outsources to OEMs for their smartphones.
Now, the two new images sensors 64 MP ISOCELL Bright GW1 and 48 MP ISOCELL Bright GM2 make use of very small pixels, thus cramming more light to form a bright picture. For the 64MP sensor, Samsung is using pixel-merging and remosaic algorithm, similar to pixel binning and pixel combining. These algorithms help in creating bright 16MP images in low light. The sensor is also able to produce full 64MP images if the conditions are optimal.
The smaller pixel size in an image sensor helps in attaining the low-light photography and with Samsung’s Tetracell technology the photography becomes more efficient. Tetracell as the name reflects, it merges four pixels into one pixel that captures more light detail in difficult conditions. The GW1 will also support real-time HDR up to 100 dB, compared to the more typical 60-80 dB range of contemporary smartphone shooters.
The GW1 include faster phase detection autofocus and has the ability to record FHD video at up to 480 FPS. The ISOCELL GM2 which is the 48MP image sensor also adopts Samsung’s Tetracell technology so as to produce better low-light shots.
Samsung ISOCELL Bright GW1 and GM2 are currently sampling and are expected to be in mass production in the second half of this year.
