Multiple smartphone brands nowadays use Samsung’s ISOCELL camera. These image sensors redefine digital imaging, revolutionizing mobile photography while providing secure mobility solutions. Recently, Samsung itself explained how the ISOCELL camera evolved to make mobile photography so advanced.

We save our memories through pictures and videos on smartphones but our phones carry limited storage and naturally, a smaller device requires pixels that make the image sensor behind each picture so tiny.

At once, packing too many tiny pixels into each image sensor to ensure high quality leads to color crosstalk, which occurs when light leaks into adjacent pixels, and degrades the definition of images.

Meanwhile, Samsung is solving this problem with its ISOCELL pixel technology. Samsung ISOCELL camera enables the smartphone to produce ultra-high-quality photos even in dark environments, taking mobile photography to next level.

Advancement of ISOCELL pixel technology: Improved image quality with greater light absorption – 

Processing light is one of the most important parts when it comes to high-quality photos. Samsung’s ISOCELL pixel technology was introduced to process and absorb more light than its traditional BSI pixels. In fact, it has reduced color crosstalk between pixels by approximately 30% and increased overall efficiency where each pixel stores up to 30% more light.

Samsung continues to refine the technology, and to improve image quality even further, the new ISOCELL technology replaces the metal grid between the color filters with a more reflective material. This innovation helps reduce optical loss and increase light sensitivity.

By increasing light sensitivity, the smaller pixels in the sensor are able to absorb more light and brighter photos with even greater detail and less noise result. Whereas, to reduce optical loss in even smaller pixels, the company adopted a new merged grid array, which removed the grids between filters of similar chromaticity, thus increasing the light-absorbing area in each pixel.

The new ISOCELL solution also introduced a new material for the thin color filter to optimize the focus of the ultra-fine pixels. Recently, Samsung has advanced photosensitivity by improving the structure of the photodiode. These innovations in small-pixel technology allow ISOCELL to fully harness the power of micro-pixels.

Pixel Binning Technology: Experience crisp pictures even in dark conditions –

Due to the limitation of smaller pixel sizes, the light absorbed by such smaller pixels may be less. This presents a significant challenge when it comes to producing high-quality photos, especially in dark settings.

In the meantime, Samsung Pixel Binning technology allows smaller pixels to mimic larger pixels by combining some neighboring pixels into one. Samsung’s TetraPixel, NonPixel, and Tetra² pixel technologies merge four, nine, and sixteen pixels, respectively, to allow our smartphones to produce ultra-high quality photos, no matter the lighting conditions.

For example, when you take a photo in a dark environment, Tetra² pixel technology combines 16 pixels into one large pixel to capture more light for brighter images. Conversely, when it’s bright, the Re-mosaic algorithm rearranges the pixel array for higher image resolution, resulting in crisper, detailed images.

Of all the incredible capabilities of Samsung smartphones, one of the most notable is the ability to meet the growing demand for high-resolution photos. These lets users experience clear, detailed photos with small, yet powerful pixels through the ISOCELL mobile image sensor.
