Samsung ISOCELL JN1
Samsung Semiconductor announced the launch of Samsung’s first 0.64um (micron, one-millionth of a meter) 50-megapixel image sensor, ISOCELL JN1. These advanced technologies are built into a 1/2.76-inch sensing area.
Currently, 0.64um is the smallest pixel size in Samsung’s mass-produced image sensors. This means that it enables higher pixels with a smaller chip size than existing image sensors, enabling slim designs while improving the shooting performance of mobile devices.
The difficulty of mobile image sensor technology is to get better image quality performance with smaller pixel sizes. This is because, in general, the smaller the pixel size, the smaller the area to receive light, and the performance of the image sensor decreases.
Samsung Semiconductor’s ISOCELL technology uses a nano-scale ultra-fine process to reduce the pixel size by 16% compared to existing pixels, and by improving the pixel structure, even small pixels can make full use of the light received and reduce light loss, thus overcoming the problem of degraded performance. In products with the same total pixels, modules made with 0.64 um pixels can reduce module thickness by approximately 10% compared to existing modules made with 0.7-micron pixels, helping to reduce the protrusion of mobile devices cameras.
Samsung Semiconductor has equipped the product with the latest image sensor technologies, such as enhanced “ISOCELL 2.0” and “Double Super PD” to capture ISOCELL 2.0 optimizes technology to increase Sensitivity by 16 percent. Especially in scenes that are both very bright and dark, such as tunnel entrances, it features “Inter-scene HDR” technology that uses image data with both high and low Gain values to provide a wide range of contrast.
To make autofocus faster, the Double Super Focus technology is also applied. With the same number of pixels, this technology doubles the number of pixels used for autofocus, enabling the same autofocus speed as “Super PD” even when there is 60% less light than before.
At the outset of development, Samsung Semiconductor worked with camera lens and module manufacturers to build an ecosystem to make the ISOCELL JN1 compatible with 1/2.8-inch products to work with wide-angle, ultra-wide-angle, and telephoto lenses on the front and back of mobile devices. easily apply them.
“Creating something tiny but powerful below the micron level requires extreme precision.” Duckhyun Chang, executive vice president of Samsung Semiconductor’s sensor business, said, “Samsung’s advanced pixel technology has once again broken boundaries by developing Samsung’s smallest pixel size image sensor. 0.64um ISOCELL JN1 enables slim and stylish smartphones to take ultra-high-resolution photos. “
