Tonight Samsung has announced their new imaging sensor technology, named ISOCELL. They say that ISOCELL will substantially increase light sensitivity by "controlling the absorption of electrons", which results in better colors in low light. We're not so sure such a thing is even possible, but they do explain things a little bit.
Unlike BSI (Back Side Illumination), which Samsung says is actually pretty limited with how much it can affect your pictures in low light, ISOCELL has a barrier between each pixel. This will reduce electrical crosstalk by up to 30 percent, and as a side benefit allows a wider field of light absorption so the camera module can actually be thinner.
The first part to use this new tech is the 8MP S5K4H5YB, which is making the rounds to hardware partners right about now. We should see the sensors in high-end devices in Q4 of this year.
Sounds interesting, even under all the PR speak. The press announcement is after the break for those interested in a little reading.

Samsung Launches ISOCELL: Innovative Image Sensor Technology for Premium Mobile Devices
New 8-megapixel sensor is the first to sample with the ISOCELL technology applied
SEOUL, South Korea--(BUSINESS WIRE)--Samsung Electronics Co., Ltd., a world leader in advanced semiconductor solutions, today announced its new advanced pixel technology for CMOS image sensors, ISOCELL. This new technology substantially increases light sensitivity and effectively controls the absorption of electrons, resulting in higher color fidelity even in poor lighting conditions. ISOCELL improves the image quality and enhances the user experience of premium smartphones and tablets that integrate sensors with this exciting new technology.
“Through advances in pixel and process technology, smartphone and tablet cameras have made it easier than ever for consumers to capture and share beautiful, clear images with the world,” said Taehoon Kim, vice president of System LSI marketing, Samsung Electronics. “ISOCELL technology is yet another innovation that significantly raises the bar in image quality, and demonstrates Samsung’s technology leadership in image sensors for mobile devices.”
The quality of an image sensor is determined by the amount of light that is accurately captured by the individual pixels within the sensor array. With the market pressure to increase camera resolution and image quality, without growing the camera size, the pixels have had to shrink, while improving their performance at the same time – a challenging task.
To meet this challenge, previous sensor technology developments focused on improving the light absorption of each pixel, and have progressed pixel technology from FSI (Front Side Illumination) to BSI (Back Side Illumination) which places photodiode at the top to maximize photoelectric efficiency. While being very effective at the time, this BSI technology also faced limitations in improving image quality as pixel sizes continued to decrease.
Building on these past advances and continuing the push toward higher quality image sensors for mobile devices, Samsung has developed ISOCELL the next generation of pixel technology, which is patent pending. ISOCELL technology forms a physical barrier between neighboring pixels – isolating the pixel. This isolation enables more photons to be collected from the micro-lens and absorbed into the correct pixel’s photodiode minimizing undesired electrical crosstalk between pixels and allowing expanded full well capacity (FWC).
Compared to conventional BSI pixels, the ISOCELL pixels decrease the crosstalk by approximately 30 percent which results in higher color fidelity to reproduce the original color with sharpness and richness, and increase the full well capacity (FWC) by 30 percent which leads to greater dynamic range.
Additionally, an imager designed with ISOCELL can feature a 20 percent wider chief ray angle (CRA), reducing the height of the camera module. This makes it suitable for slim and small form factor mobile devices with challenging low z-height requirements.
As the first Samsung image sensor to adopt this new technology, the S5K4H5YB 8Megapixel imager utilizes a 1.12um ISOCELL pixel and has a 1/4inch optical format. The S5K4H5YB is currently sampling to customers with mass production scheduled for Q4 2013.
According to market research firm Techno System Research, in 2014, approximately 66 percent of smartphones will feature image sensors with 8Mp or higher resolution.
