The size specification of the Sony LYT-828 sensor is 1/1.28 inch, designed specifically for high-end mobile phone cameras, supporting 50 megapixel ultra high definition shooting. The Sony LYT-828 is an upgraded model of the LYT-818, with a size of 1/1.28 inches, mainly suitable for the primary and secondary cameras of smartphones. Sony launched the LYT-828 camera sensor, a new generation 50 megapixel 1/1.28-inch CMOS image sensor under the LYTIA brand, on June 26, 2025. The parameter specifications of LYT-828 are as follows: The unit pixel size of LYT-828 is 1.22 μ m, which can be increased to 2.44 μ m through four in one technology, and it also supports full pixel dual core focusing function. The sensor adopts advanced 22nm process technology and has been designed with low-power optimization for the logic circuit. In addition, its video performance is also quite outstanding, not only supporting 4K video recording, but also incorporating Loss Less Exposure technology to ensure the high dynamic range effect of HDR can be maintained during zooming.
Continuing the basic performance of LYT-818 and equipped with the newly developed HDR technology “Hybrid Frame HDR (HF-HDR)”, the image quality has been further improved. HF-HDR “technology is a comprehensive technology that integrates multiple HDR functions, including two core technologies: one is single frame HDR technology based on the” Dual Conversion Gain “installed in traditional products, and the other is multi frame HDR technology achieved by synthesizing DCG data and short exposure frames in the application processor in the later stage.
By integrating these two HDR functions, LYT-828 achieves a leading dynamic range of over 100dB in SSS mobile CMOS image sensors. When shooting in high light ratio scenes, not only can it significantly suppress underexposure in dark areas, but it can also effectively suppress overexposure in bright areas, making the imaging effect close to what the naked eye can see. Meanwhile, with the support of the “Loss Less Exposure (LLE)” technology that enhances the freedom of exposure control, the utilization efficiency of light is effectively improved, further improving the Signal to Noise Ratio (SNR). HF-HDR technology can maintain HDR effect and achieve high-quality imaging even when using zoom.
The LYT-828 camera sensor is also equipped with a special circuit that efficiently converts the charge generated by the photodiode into voltage, greatly reducing random noise. Therefore, in dim shooting environments, it can effectively suppress the graininess caused by noise, making the picture more delicate and realistic. Meanwhile, by reducing the power consumption of sensors, especially logic circuits, HDR functionality can be continuously used during preview and video recording. Therefore, users can record images with HDR quality that is equivalent to the preview effect of a smartphone screen.
