◆ 200 million pixel image sensor 'ISOCELL HP1'
'ISOCELL HP1' is packed with 200 million pixels in a size that fits comfortably in a smartphone, and the pixel size is only 0.64 μm, which is a very small size.
The smaller the pixel size, the less light each pixel can receive, and the darker the photo. To solve this problem, 'ISOCELL HP1' uses a technology called 'ChameleonCell' that treats multiple pixels as one pixel depending on the situation. With ChameleonCell, 'Take a picture of 200 million pixels in a bright place where you can secure a sufficient amount of light' 'Treat 16 pixels as 1 pixel (pixel size 2.56 μm) in a dark place and take a picture of 12.5 million pixels' It becomes possible.
In addition, 'ISOCELL HP1' also supports movie shooting at 8K / 30fps. When shooting an 8K movie, by treating 4 pixels as 1 pixel, it behaves as an image sensor equivalent to 50 million pixels (8192 x 6144 pixels), and it is possible to shoot an 8K movie without trimming or reducing it. That is.
◆ High-speed autofocus compatible image sensor 'ISOCELL GN5'
At the same time as the 'ISOCELL HP1', the 'ISOCELL GN5' with a pixel size of 1.0 μm compatible with the high-speed autofocus technology Dual Pixel Pro developed by Samsung was also announced.
The mechanism of Dual Pixel Pro is explained in the following movie.
In a general camera sensor, one light receiving part is prepared for each pixel, but ...
Dual Pixel Pro realizes high-speed autofocus by preparing two light-receiving parts for each pixel and using the light detected by each light-receiving part for autofocus.
In addition, by preparing two types of light receiving parts, one that is divided vertically and the other that is divided diagonally, the difference in light from all directions is detected and the autofocus performance is improved.
Both the 'ISOCELL HP1' and 'ISOCELL GN5' announced this time are being supplied with samples for smartphone makers, and it is expected that smartphones that use both sensors will appear in the near future.
