Samsung announced yesterday (24) a new sensor for smartphones that can be only 0.5 cm wide, with 43.7 megapixels of resolution and the name ISOCELL Slim GH1. The manufacturer claims that this is the first sensor that has pixels 0.7 μm in size – which is 0.001 millimeter.
The size occupied by each pixel was already small when the Korean brand launched the sensors of 64 and 108 megapixels, with 0.8 μm. Having an even smaller sensor than the already small one that is present in so many smartphones is a challenge and an advantage.
The challenge part is that the smaller the pixel size, the less light it will be able to receive and that is a physics detail. Companies solve this dilemma by merging four pixels into one, increasing the light reception in the final image and decreasing the exaggeration of resolution.
In the case of this sensor from Samsung, the original image is 43.7 megapixels and the photo can have much more detail and light, with 10.9 megapixels – which is great even for printing in standard size photos, with 10 x 15 centimeters .
The advantage is that with a smaller sensor, more space is left for more features on the smartphone. Generally this can also mean that the cell phone can be thinner, which almost nobody asks for and the industry almost always does.
Even so small, the ISOCELL Slim GH1 sensor can record 4K videos, but without losing field of view. The magic follows the same pattern of grouping more pixels into one, originally recording at 7,968 x 5,480 pixels to generate a 3,984 x 2,740 pixel file, which fits the 4K 2160p – which can be up to 60 frames per second.
In addition, the sensor supports electronic stabilization and enhanced phase detection, which helps adjust the focus more quickly. The sensor goes into mass production by the end of this year, plenty of time for the launch of the Galaxy S11, or some Galaxy A with greater powers in the camera.
