Samsung announced a new leap forward for CMOS sensors in mobile cameras today dubbed, ISOCELL. The ISOCELL tech is supposed to increase the sensors light sensitivity which in turn would help control electron absorption giving the end result higher color fidelity even in low-light conditions.
“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.”
We can speculate that Samsungs flagship line of phones, the Galaxy series, might be seeing this technology in the next generation. Improving the sensor so much may leave little need to continue increasing megapixel capacity. Most photographers know that higher megapixels does not equal a better camera or picture.
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.
So who thinks Samsung will announces improved camera technology on the Samsung Galaxy series at their next Unpacked event?
