Samsung has just announced new image sensors that are joining the ISOCELL range. Both are thinner than their predecessors and have been designed for smartphones with large screens without bezels. Specifically, these are the 12 megapixel 1.28 micrometer ISOCELL Fast 2L9 sensor (with Dual Pixel technology) and the ultra-small ISOCELL Slim 2X7 24 megapixel and 9 μm (with Tetracell technology).
Small sensors for slim smartphones
Samsung classifies its ISOCELL image sensors into four categories: Fast, Slim, Bright, and Dual, depending on their key characteristics. As demand for slimmer smartphones increases, the company's new image sensors offer more resolution in a smaller size. The new Dual Pixel ISOCELL Fast 2L9 image sensor enables ultra-fast autofocus with a smaller pixel size. Samsung has reduced the pixel size from 1.4 μm in the previous model to 1.28 μm in the Fast 2L9.
The smaller pixel size will allow the Fast 2L9 to accommodate thinner camera modules. Also, Dual Pixel technology activates the depth of field effect for bokeh images with a conventional single lens camera.
Samsung claims that the ISOCELL Slim 2X7 is the first sensor to have a pixel size of less than 1.0 μm. Despite its 0.9 μm pixel size, it provides high color fidelity with less noise. This is due to the DTI (Deep Trench Isolation) technology, which has been remarkably improved. For its part, the small pixel size also offers the possibility of installing a 24 megapixel image sensor in a thinner camera module.
It also features Tetracell technology, which enables the sensor to take brighter photos in low-light environments and more detailed photos in well-lit environments. It does this by merging four neighboring pixels so that they work as one to increase the sensitivity to light. Samsung has announced that it will continue to develop these sensors so that we can enjoy improvements in the next cameras of its devices.
