As early as 2019, Samsung Electronics launched 0.7μm-level pixel process products. This time, four new ultra-small size products have been added, and it has taken the lead in building a variety of pixel product lines based on 0.7μm-level pixel technology.
Samsung Electronics has added new options for global mobile device manufacturers to choose ultra-small size, high-pixel sensor products, and more products are expected to install image sensors based on 0.7μm-class pixel processes.
Generally speaking, the smaller the pixel size, the smaller the photosensitive area, and the lower the image quality will be. Therefore, while reducing the pixel size, it is also very important to improve performance.
In order to enable the ultra-small image sensor of 0.7μm to achieve high-quality images, Samsung Electronics adopted Samsung Electronics’ patented technology ISOCELL Plus, changed the optical structure of pixels, and used new materials to minimize light loss and interference between pixels.
At the same time, the Smart-ISO technology is adopted, which can automatically adjust the ISO value according to the amount of incoming light, improve color reproduction and minimize noise.
Samsung Electronics will install a new generation of ISOCELL 2.0 technology on the 0.7μm ultra-small size products launched in the fourth quarter, which is expected to further reduce light loss and interference between pixels.
ISOCELL2.0 is a technology that minimizes light loss by improving the barrier structure between color filters. This technology can increase the sensitivity of the sensor (Sensitivity) by up to 12%, even if the pixel size is reduced, the image quality is still guaranteed.
On the other hand, from the perspective of a high-definition image sensor, a pixel size difference of 0.1 μm will not only affect the volume of the sensor, but also greatly affect the height of the camera module.
The 108-megapixel sensor based on the 0.7μm-level pixel process can reduce the volume by up to 15% compared with the sensor using the 0.8μm-level pixel process. The size of the image sensor is reduced, and the height of the camera module can be reduced by up to 10%, so as to solve the problem of the camera bulge to a certain extent, and provide more freedom for global mobile device manufacturers to design products.
Park Yong-in, deputy general manager of Samsung Electronics System LSI Division and Sensor Division, said that Samsung Electronics launched a 1.0μm-level pixel process in 2015, followed by a 0.9μm-level pixel process in 2017 and a 0.8μm-level pixel process in 2018. In 2019, 0.7μm-level and 108 million pixel products were launched, always leading the innovation trend of the global sensor market. The upgrade of the product line of 0.7μm-class new products not only means that Samsung Electronics will further expand the ultra-small size, high-pixel sensor market, but also announces that Samsung Electronics will continue to develop sensor innovation technologies to expand business areas.
Samsung Electronics currently has ISOCELL HM2, GW3, JD1 and other products based on 0.7μm pixel technology, all of which have been mass-produced, and GM5 can provide samples.
Details in detail
Smaller, more powerful 108-megapixel image sensor ISOCELL HM2
ISOCELL HM2 is Samsung Electronics’ third 108-megapixel product, and the first 108-megapixel image sensor using a 0.7μm-level pixel process.
* Samsung Electronics 108 million pixel products
– ISOCELL HM1 (0.8μm, using the technology of nine pixels in a dark environment)
– ISOCELL HMX (0.8μm, using four-pixel integration technology in dark environments)
The volume of this product is 15% smaller (1/1.52 inch) than the previous 108-megapixel image sensor based on a 0.8μm-level pixel process, so the height of the camera module can be reduced by 10%. With the increasing number of cameras installed in smartphones, this product is expected to solve the problem of expanding and protruding camera parts to a certain extent.
Super PD (Super Phase Detection) technology can detect the phase difference of the subject, quickly find the focus point, and provide a stronger autofocus function.
Samsung Electronics’ exclusive technology that combines 9 adjacent pixels into one in dark conditions can capture bright and vivid images no matter where they are, while allowing the subject to be zoomed in three times without affecting the picture. quality.
ISOCELL GW3 that clearly presents extreme sports images with 4K30 frames
The 1/1.97-inch, 64-megapixel ISOCELL GW3 is more suitable for shooting objects or people moving quickly, such as sports competitions.
The product also uses an enhanced version of the Super PD technology and Electronic image stabilization (EIS) function, which can clearly present moving objects or people. In particular, it can shoot 4K (3840 x 2160) high-definition images at 60 frames per second, making it suitable for action cameras that shoot extreme sports.
Samsung Electronics plans to further expand the 64-megapixel products that were originally only mounted on cutting-edge smartphones to popular products, leading the development of the high-definition market.
ISOCELL GM5 supporting ultra-wide-angle, folding zoom
The 1/2.55-inch, 48-megapixel ISOCELL GM5 can support ultra-wide-angle or Folded-zoom photography.
The foldable zoom function is a function that can enlarge a subject at a distance by 5 times for shooting. In order to install this function on a smartphone, the image sensor is not superimposed on the camera lens, but a periscope structure arranged next to it. .
If the image sensor is large, the height of the foldable zoom camera module will increase, which will lead to an increase in the thickness of the mobile phone. Due to its small size and high pixel count, ISOCELL GM5 is very suitable for thin and light smartphones with folding zoom function.
In particular, Samsung Electronics has adopted ISOCELL 2.0 technology for the first time on this product, which has improved color reproduction and sensitivity compared to ISOCELL Plus.
In addition, the product also adds a line-interleaved HDR (staggered High Dynamic Range) function, which differentiates the pixel exposure time in line units and fuses images of different brightness into one photo. Compared with the real-time HDR technology to distinguish the exposure time of each pixel, it can Increase the speed of image processing.
The product also uses “Tetracell” technology that combines four adjacent pixels in a dark environment. 0.7μm pixels become large 1.4μm pixels, so compared with 3D HDR, image noise can be reduced, sensitivity can be increased, and sharper images can be captured.
In addition, this product can also perform ultra-high-definition (1920×1080) high-speed video recording at 480 frames per second, which is the same level as a single-lens reflex camera (DSLR).
ISOCELL JD1 for bezel-less designs
The 1/3.14-inch, 0.7μm pixel-level, 32-megapixel ISOCELL JD1 is an ultra-compact image sensor. The volume of the camera module is equivalent to 0.9μm, 20-megapixel, and 1.0μm, 16-megapixel modules.
Since more pixels can be packed into a smaller image sensor, it is very suitable for the HIAA (Hole in Active Area) Display that is drilled on the front of the smartphone to put the camera, and it is also one of the solutions for bezel-less design.
In addition, this is the first product of Samsung Electronics to adopt the line-interleaved HDR function, which can capture bright and vivid images even with low-pixel image sensors.
