Samsung Electronics recently announced their new ISOCELL image sensors, designed to be small and fast for use in Internet of Things (IoT) devices. If you are unfamiliar, the Internet of Things usually refers to home appliance and other devices becoming smarter and being able to connect with each other. The two Samsung Image Sensor models released are the ISOCELL Fast 2L9 and then ISOCELL Slim 2X7—both small and without a camera bump. They both have their own merits, and both are good for what they will be used for. Samsung has four main categories for image sensors—Fast, Slim, Bright and Dual, depending on the attributes of the given image sensor.
ISOCELL Fast 2L9
This sensor falls under the “Fast” category of Samsung’s image sensor lineups. Employing Dual Pixel technology, the sensor pixel size has reduced from 1.4μm to 1.28μm. With a quick auto-focus, the camera module can easily track fast moving objects without losing sight of them—even in low light. The decreased pixel size at first may strike some as a disadvantage, however, it allows Samsung to include two photodiodes in each pixel instead of one. This camera sensor also allows for the bokeh effect even though it only has one camera module.
ISOCELL Slim 2X7
Being the slimmer model (hence “slim”), this camera module has an emphasis on making things as small as possible—including the pixel size. With a shockingly low 0.9μm pixel size, this camera module is the first in the world to have a pixel size below 1μm. It achieves this through a 24MP camera and Deep Trench Isolation (DTI), expanding the light information held per pixel and decreasing the color crosstalk. This is simply color bleeding into other pixels in a photo. This camera module employs a new Tetracell technology, which can produce brighter images in low light and more detail in bright light. In low light, it merges 4 pixels into one while in bright light it uses a mosaic algorithm to produce high-quality images.
These camera modules are designed both for mobile phones and IoT devices. Do you think they can compete with the best Sony has to offer in terms of phone camera modules?
