Samsung has collaborated with the Japanese tech firm Fujifilm to develop the ISOCELL Plus technology. This new technology aims to improve the light sensitivity and color fidelity offered by the camera sensors developed by the South Korean tech giant. Samsung noted in its announcement that for CMOS camera sensors, like its ISOCELL modules, to capture the highest quality image, it needs to hold as much light as possible and transmit the correct light information to the photodiode. The original iteration of the ISOCELL technology, which was launched back in 2013, already attempted to resolve this issue by introducing a physical barrier that separates neighboring photodiodes. This physical barrier improves image quality by reducing color crosstalk, the phenomenon wherein light information falling on one pixel is also detected by the adjacent pixels. In addition, this technology also increases the amount of light absorbed by the imaging modules compared to the more traditional backside-illuminated sensor design.
However, the ISOCELL Plus technology aims to further improve the ability of the camera sensors to absorb and hold light by replacing the metal grids that separate the photodiodes with a new material developed by the Japanese tech firm Fujifilm which reflects less incoming light. The South Korean tech giant noted that by taking advantage of the new material, the ISOCELL Plus technology could offer up to a 15-percent improvement in light sensitivity and higher color fidelity compared to the older versions of ISOCELL sensors. For smartphone users, this technology could mean more color-accurate and clearer images, and it will also enable the development of high-resolution sensors with pixel sizes of 0.8-micrometer or smaller and resolutions of 20-megapixels or higher.
Samsung has been actively improving its ISOCELL sensors through the development of new technologies and hardware designs. For example, the South Korean tech giant has developed the Tetracell technology for its ISOCELL Bright sensor. This technology merges four adjacent pixels together and processes them as a single unit, which should result in improved low-light performance. In addition, the tech firm is also working to accelerate the sensor’s autofocusing through the use of a three-stack design, which is already used in the ISOCELL Fast sensors.
