Samsung today has introduced two new image sensors; the ISOCELL fast 2L9 and Slim 2X7. The Fast 2L9 is a 1.28 micrometer 12-megapixel camera sensor while the Slim 2X7 is an ultra-small 0.9μm 24Mp ISOCELL Slim 2X7 with Tetracell technology. Samsung has four categories for their camera sensors; the fast, slim, ultra and bright which the company uses depending on the product.
The new Fast and Slim image sensors offer excellent picture quality and will ship in smaller chip packages that will provide great picture quality even in low-light without a camera protrusion.
The Fast 2L9 is dual pixel sensor that delivers ultra-fast auto-focus as it comes with reduced pixel-size compared to its previous sensor’s 1.4μm to 1.28μm. As it is a dual pixel sensor, two photodiodes are employed in each pixel thus enabling fast auto-focus, and the sensor can fix the focus lock on not just still objects but also on moving ones even in artificial and low-light conditions.
Another advantage of the Dual pixel technology is that it allows you to take depth-of-field images or bokeh images through single lens camera. On the other hand, the ISOCELL Slim 2X7 is the first image sensor in the industry to have pixel size below 1.0μm. It comes with 0.9μm and is capable of providing high-color reproduction and less noise in the images especially in the low-light. Thanks to the improved ISOCELL technology deeper DTI (deep trench isolation), it reduces color crosstalk and holds on to more light.
The Slim 2X7 enables 24-megapixel sensor in a thinner camera module thus allowing flagships to take high quality and resolution images. Tetracell technology lets the camera sensor take brighter photographs in the dark and more detailed ones in well-lit environments. It merges four neighboring pixels to work as one to increase light in the low environments and in bright conditions it uses a re-mosaic algorithm to produce full resolution images.
