Do you remember the cooperation of the Chinese Xiaomi so Samsung in the field of mobile cameras? The South Korean manufacturer has now officially introduced its new high-end photographic sensors. Specifically, 200 MPx ISOCELL HP1 and also 50 MPx ISOCELL GN5.
New ISOCELL photo sensors
Earlier this year, the first reports appeared that Samsung was preparing a new photo sensor for smartphones with a resolution of up to 200 MPx. Now this sensor is a reality and the South Korean giant has introduced up to two sensors in total.
As for the first of the pair, Samsung introduced the model ISOCELL HP1. This is the world's first 200 MPx photo sensor with a pixel size of 0,64 μm. The second is the 50 MPx model ISOCELL GN5, which is the first photo sensor to use the technology Dual Pixel Pro with omni-directional focus and two photodiodes in one pixels as small as 1,0 μm.
200 MPx sensor: Samsung ISOCELL HP1
Samsung ISOCELL HP1 offers a completely new ChameleonCell technology. It is a binary pixel splicing technology that uses a two-to-two, four-to-four, or whole-pixel layout, depending on the environment. It can also record up to 8K video at 30 fps, with minimal field of view loss.
ISOCELL HP1 merges four adjacent pixels to reduce the resolution to 50 MPx, capturing 8K video without having to crop or reduce the entire image resolution. In a low-light environment, a photo sensor with a pixel size of up to 12,5 μm is then changed up to 2,56 MPx by merging 16 adjacent pixels.
As a result, the sensor gets more light, is more sensitive to light and can create clearer and more accurate photos even in poor lighting conditions. On the other hand, in a bright, outdoor environment with enough light, this sensor can also capture high-end photos in ultra-high resolution.
50 MPx sensor: ISOCELL GN5
Samsung ISOCELL GN5 is consequently the first photographic sensor that also offers technology in its equipment Dual Pixel Pro. It is an all-round autofocus technology. It can significantly increase autofocus capabilities, all with a pixel size of just 1,0 μm.
The mentioned technology Dual Pixel Pro uses two photodiodes in each 1,0 μm pixel, horizontally or vertically, to detect pattern changes in all directions. As Samsung says, with one million multi-directional phase-detection photodiodes covering all areas of this sensor, autofocus becomes virtually instantaneous.
To achieve this result, the manufacturer is using a technology called Front Deep Trench Isolation (FDTI), for the first time in the mobile camera industry. Despite the microscopic size of the integrated photodiodes, FDTI technology allows each photodiode to absorb more light, which also improves the full capacity of these photodiodes and reduces imperfections within individual pixels.
Samsung already supplies both sensors, ISOCELL HP1 a ISOCELL GN5, equipment manufacturer. This means that new smartphones with these cameras can be expected around the end of this year or early 2022. There is also the possibility that the upcoming Galaxy S22 series may be equipped with the aforementioned new 200 MPx photo sensor. However, these are still unconfirmed and unofficial reports.
