According to Samsung, “In the existing pixel structure, metal grids are formed over the photodiodes to reduce interference between the pixels, which can also lead to some optical loss as metals tend to reflect and/or absorb the incoming light. For ISOCELL Plus, Samsung replaced the metal barrier with an innovative new material developed by Fujifilm, minimizing optical loss and light reflection.”
Samsung is claiming that the new sensor will result in high color fidelity, and a 15% boost in light sensitivity which should result in better low-light photos. Samsung is expected to show off the new ISOCELL Plus sensor at MWC Shanghai later this week. It is unclear when we might see it in their new smartphones, but we have heard rumors that the Galaxy Note 9 could feature an improved camera, and we wouldn’t be surprised if there will be an emphasis placed on low-light photography. Either way we’ll have to wait and see.
