NVidia Chimera: how it works and what are the photo advantages

tegra-4-chimeraNVIDIA today unveiled new GPU Chimera dedicated devices and mobile platforms (smartphones, tablets etc). According to the press release, Chimera is the first processor that will be dedicated for camera mobile beginning with this spring and provides information from the sensor processing in a manner similar to the image processor DSLR cameras. Moreover, Chimera boasts HDR mode “always on”, which promises obtain images with a wider dynamic range and a new way of shooting panoramas, which allows obtaining large panorama by moving the device in any direction (and not just horizontally or vertically as it does so far).

Tab-To-Track function allows tracking the subject in the frame and maintain focus even if it is moving. However, the main issue that stands out Chimera remains HDR mode.

But what actually works Chimera? And what are the benefits?

NVidia Chimera boasts primarily with performance HDR (High Dynamic Range) mode and “HDR always on”. What does this mean and what we do for you? It’s pretty simple: the market demand megapixels, in translation photo sensor that is as large resolutions. Meanwhile, mobile gadgets manufacturers can introduce their devices sensors in May with more general physical dimension that we must boast more compact gadgets (the thinnest smartphone, easiest tablet etc). The main problem is that the size of the large number of megapixel sensors is collide head.

Current technology does not allow for a wider dynamic range if the physical dimensions of the pixels are too small and, thus, are not able to absorb enough light. Currently, the mobile camera sensors shows its limitations especially in situations where the differences are characterized by high contrast. The phenomenon of “sky burned” or lack of detail in the shadows, so post-processing HDR photos is a solution that allows obtaining images with a wider dynamic range even on phones.

So, in short, the main advantage of the devices will adopt the new NVIDIA Tegra processor 4/ Chimera is that it can be further equipped with photo sensors huge resolutions (8, 13 megapixels, etc.) but – at the same time – will compensate for the lack dynamic range due pixels that can not absorb enough light through NVIDIA’s hardware algorithms. The result: better images despite higher resolutions. At least theoretically, until proven otherwise …

Another solution would be to reduce the resolution and number of pixels to equip sensor pixel sizes generous. Yes, the solution presented yesterday HTC HTC One (I looked this solution here). Comes with a sensor that provides only a resolution of 4 megapixels but only boasts a degree of light absorption of 3.3 times better than with current sensors. So pictures will have a better dynamic range, without the need for HDR processing.


Tegra 2 3D and Tegra 3 Quad-core Cortex-A9 to arrive in 2011

tegra2-logoAfter the release of the first smartphone with dual-core Tegra 2 chipset, Nvidia prepares two new chip versions, the Tegra 2 3D and Tegra 3 Quad-core.

The future Tegra 2 3D processor will be available in two models, one for Tablet PC’s named T25 with dual Cortex-A9 that will offer a speed up to 1.2 GHz (5520 MIPS). The Tegra 2 3D model for smartphones is named AP25 and has the same features as the T25 version for Tablets. This new Tegra chipset is expected to be presented at the MWC 2011.

According to the image, the release date of Tegra 3D will be somewhere in Q1 2011.

And that’s not all, Nvidia is preparing another Tegra chipset, named Tegra 3 Quad-core. Tegra 3 T30 will be the version just for tablets and is capable to run at 1.5 GHz frequency, with 3X graphics performance and Ultra Low Power (ULP). Also, T30 is capable to show Blu-ray videos and support up to 1920 x 1200 pixels screen resolution. The Tegra 3 Quad-core version for smartphones is named AP30 and has some similar features as the T30 but with a small resolution for screens, 1366 x 868 pixels.

The release date of Tegra 3 Quad-core is expected to be somewhere in Q3 2011, but it will probably show up in some great new products at the CES 2012.

Motorola cooperates with Google for the Android 3.0 tablet

Motorola Android 3.0 tabletA new project featuring Motorola and Google is starting to take shape. It appears that Google is designing not only the hardware but is also very involved in the specification settings, like the user interface and will apply the Android 3.0 on it.

This cooperation between Motorola and Google is similar with the one for Google G1 smartphone. Motorola Android 3.0 tablet will feature a 10.1 inch Sharp display which is thinner than Apple’s tablet, and NVIDIA’s dual-core Tegra 250. The Motorola tablet design will carry a FiOS TV angle and probably the Stingary name.

The volume production will start by the end of 2010, which means that this new Motorola tablet will probably be launched at the end of 2010 or beginning of 2011. The 2011 selling target for Motorola Android 3.0 tablet is about two million, which is equal with Apple’s iPad sellings in less than two months.

But before this Android 3.0 tablet will appear, another competitor, made by HTC and Google, named Google Chrome OS tablet is rumored for November 26. Both of these tablets are made in cooperation with Google and both of them will be released on Verizon.
