![]() ![]() ![]() The wide-angle camera includes a first-of-its-kind five-axis optical image stabilization (OIS) system that, when paired with proprietary algorithms, promises to counter hand shake better and provide sharper images at lower ISO settings, resulting in photos with less noise. F2.4 'telephoto' camera with a 13MP image sensor, which has 5x Hybrid Zoom and 20x Digital Zoom. The third camera onboard is a 52mm full-frame equiv. The ultrawide camera has a 110-degree field of view and also includes pixel binning to increase the effective size of photosites to improve low-light performance. F2.2 camera with the same 1/1.56" 50MP IMX766 sensor. The primary wide camera (25mm full-frame equiv, F1.7) has a 1/1.56" 50MP IMX766 image sensor while the onboard ultrawide is a 15mm full-frame equiv. The NPU also uses what Oppo refers to as a Dual Image Pipeline with 'double raw super sampling.' What that means is MariSilicon X works with RGBW sensors to capture RGB and W signals separately then fuse the data together to get an '8.6dB improvement in signal-to-noise ratio and a 1.7x improvement in texture quality.' Oppo says applying its algorithms on the original imaging data yields an 8dB signal-to-noise ratio (SNR). In December, we wrote, "MariSilicon X can process up to 8.5GB per second with shared DDR memory and uses a 20-bit HDR imaging pipeline that can run algorithms directly on RAW data, rather than using the compressed data as some other chipsets do. Compared to a Snapdragon 888-powered smartphone, the MariSilicon X can process its AI noise reduction algorithm 20 times faster while using half the power. As a reference, the iPhone 13 Pro and 13 Pro Max top out at 15.8 TOPS. The MariSilicon X chipset can process up to 18 trillion int8 operations per second, (TOPS) at a rate of 11.6 TOPS per watt. Oppo has now announced the Find X5 Pro flagship smartphone, its first smartphone equipped with the MariSilicon X Imaging NPU. The chip promises to improve the imaging capabilities of mobile photography, including a 20-bit HDR pipeline. The 6nm chipset, MariSilicon X, includes the NPU, an image signal processor (ISP) and a custom memory architecture. In December, smartphone manufacturer Oppo announced the successful development of its neural processing unit (NPU). ![]()
