Chimera is NVIDIA's branding for their computational photography architecture that first hailed on their Tegra 4. Now on the Tegra K1, the massively parallel processing architecture of the Kepler GPU combined with the updated CPU cores and most notably, dual upgraded image signal processors (ISPs), NVIDIA has conjured the Chimera 2.
With such an advanced ISP and with two of them, NVIDIA claims to possess state of the art Area Processing that's much required when using increasingly higher resolution imaging sensors. Considering the ISP on Tegra K1 boasts support for up to a 100MP camera sensor (theoretically), NVIDIA needs to ensure its hardware is ready to tackle the kind of throughput (though we wonder if the recording media would be fast enough for it).
Combined with the performance of the Tegra K1, the GPU can easily support advanced on-the-fly effects such as live local tone mapping (LTM) preview, Pano paint, video stabilization (auto-correction for rolling shutter, handshake, etc.), live HD video filters (such as sketch, oil patch, cartoon, etc.) and many more live preview effects without delays or performance penalty.
