Samsung launched the world’s first mass-produced 108-megapixel cellular digicam sensor in 2019. Final week, Samsung launched the world’s first 200-megapixel cellular digicam sensor, the ISOCELL HP1. Nevertheless, Samsung has plans to do even higher. The South Korean firm revealed final yr that it desires to develop a 600-megapixel digicam sensor.
576-Megapixel Sensor For Cars
Haechang Lee, senior vp of Samsung Electronics Automotive Sensors, used an attention-grabbing slide in his speech on the SEMI Europe Summit. The slide exhibits an outline of digicam sensor pixel measurement and backbone developments since 2000. Additionally, it exhibits that Samsung plans to launch a 576-megapixel digicam sensor someday in 2025. Nevertheless, this sensor might not seem in smartphones however in vehicles.
“For our newest 108Mp picture sensor, the ISOCELL Shiny HM1, we carried out our proprietary ‘Nonacell expertise,’ which dramatically will increase the quantity of sunshine absorption pixels are able to. In comparison with earlier Tetracell expertise which incorporates a 2×2 array, the three×three pixel construction of Nonacell expertise permits, as an example, 9 0.8μm pixels to operate as one 2.4-μm pixel. This additionally mitigates the problem raised by low-light settings the place mild info is commonly scarce.”
The Samsung web site talked about earlier that the decision of human eye matching is about 500 megapixels, and the corporate hopes to surpass this degree. With its 576-megapixel sensor, it could obtain this feat. Nevertheless, this doesn’t essentially imply that it is going to be handy to make use of in smartphones. Quite the opposite, such sensors can be utilized in autonomous automobiles, drones and medical tools. Autonomous automobiles additionally want super-powerful chips to course of photographs and movies from such high-resolution sensors. So the idea that such a sensor received’t seem on smartphones is sort of logical.
Samsung ISOCELL GN2 Sensor
Samsung’s 50-megapixel ISOCELL GN2 sensor will likely be a sensible choice for smartphones due to its massive pixel measurement (2.8µm), dual-pixel autofocus, wonderful HDR processing, 4K 120fps and 8K 30fps video recording, and low noise. The Galaxy S22 and Galaxy S22+ might use this 50-megapixel sensor.
The latter can take 100MP pictures by re-arranging the colour pixels utilizing “an clever re-mosaic algorithm”. The 100MP pictures have three 50MP layers in Inexperienced, Blue, and Purple. As a consequence of a particular algorithm, the sensor overlays, upscale, and merges the picture to supply high-resolution images.
Additionally, that is Samsung’s first sensor to make use of Twin Pixel Professional. The latter is the corporate’s most superior PDAF answer. As a substitute of splitting all of the pink, inexperienced, and blue pixels vertically, the inexperienced pixels are break up diagonally. The highest and backside can learn phased variations in addition to the left and proper sides. It ends in quicker and extra correct autofocus, particularly in tough circumstances similar to low-light environments or fast-moving objects.
