The Acer Aspire series transform 2D content into 3D

It should be said of the 3D is a candidate for a long time. In fact, despite the fact that the principle is really new, start the 3-dimensional images arrive in private: 3D TV, 3D camera, 3D games and 3D laptop now. Yes, read that Acer has recently announced the availability of the first portable computer on a 3D display technology, announced the notebook Aspire 5738DG basis.

This technology is passive. You must be a polarizing screen and specially treated glasses whose lenses are also polarized. One of the great strengths of this machine is that it offers a great 2D program and display multimedia content, but it can transform 2D content into 3D content. This is possible by developing a software solution TriDef, a Canadian specialist in 3D. Imagine rediscovering your library and most of your games in 3D version ...

Nvidia is now offering an alternative to using a technology called active, a graphics card, eyeglasses, electronics, and an infrared sensor, used for sending and receiving information. The first laptop to the manufacturer of 3D Vision technology feature, the Santa Clara G51J 3D model from dell Inspiron 1545 (Read this news). Others should follow. We wanted to know what exactly the model was capable Acer Aspire 5738DG 15.6-inch and what were the possibilities of 2D, 3D, in terms of performance and rendering. Also here is a complete test of the Acer Aspire 5738DG.

The PC Acer Aspire 5738DG is based on the same chassis and the same components as the model Aspire 5738PG, which offers a touch screen. Here, this is a screen of images and videos, but also 3D gaming shows. Externally, the Aspire 5738DG is done is different.

Our test model has imprinted a dark blue hull with painted an Acer logo. The lower part of the computer is slightly domed and features smooth curves and not protruding.

The underside is matte black. There are two panels that provide access to hard drive and allow the computer's memory.

On the left side is the power connector, an RJ45 Ethernet 10/100/1000 connectivity, HDMI output, a D-Sub output, two USB ports, audio line input, microphone input, headphone output S / PDIF .

On the wafer front surface there is a memory card reader. On the right side are two USB ports, a DVD player / DVD burner and an RJ11 modem.

Note that both hands to open the computer to avoid it falling backwards need. The screen is held in its closed position by a snap hook. Open, the Aspire 5738DG did very well. It was almost like in the presence of an HP laptop with slightly elevated flat areas near the keyboard.

Control the touchpad to mouse movements enables multipoint zoom in and out by pinching or spreading two fingers. It is also possible to rotate an image by a rotational movement. It is easy and fun. Note that it is possible to disable the touch pad located on a certain button in the upper right corner of the surface. A double-tilt bar, you can click the left and right mouse button. Errors are few, because it is impossible, in the middle.

Above the keyboard are five buttons. Leftmost enable or disable the Wi-Fi module, the second is used for Bluetooth and the third to the backup utility to restart data from the computer. Two buttons, more eccentric right to increase or decrease the volume.

Finally, it should be noted the presence of a marked P-key, which launches an application from a customizable list. For us, the battery of the Acer Aspire One 1551 success. The 104 buttons appear to float. The step distance is 0.18 mm. We like. The input is very nice and soft. Input can be pretty fast with a well calibrated. Of this 15.6-inch model, a keyboard is present, but not necessarily at the expense of the room from the other keys.

The speakers are cleverly hidden in a micro-perforated grille above the keyboard. The computer is Dolby Home Theater certified, it can provide a pretty good sound quality compared to others. The screen has painted over black borders. It's brilliant. Nevertheless, the reflections are very limited, if you have a window directly into their backs. Upstairs there is a webcam. With 2.8 kg, the Aspire 5738DG is not very easy.

Our test model Acer Aspire 5738DG has a processor Intel Core 2 Duo T6600 running at 2.20 GHz with 4 GB of RAM. The Windows Experience Index is 4.1. It runs Windows 7 Home Premium 64 bit.

The hard drive is 500 GB with 452 GB is actually available and you can count on a player / DVD burner. The ATI graphics card is signed. It is a Radeon 4570. It may be a resolution of 1366x768 pixels on the screen. Our tests have allowed us to get a read speed of 260MB / s and the maximum writing speed of 222 MB / s.

According to HD Tach, 16.7 ms access time and data exchange is not very regular. It falls towards the end.

You have to realize that the hp  Pavilion DV6000 has a strong power and polarized screen. So a special screen. A line is polarized in one direction and a line is polarized in the other direction. To see the 3D, using the glasses with polarized lenses. A glass is polarized in one direction and the other, in the other direction. They come with the computer.

The advantage of this technology is primarily the cost of glasses (3-5 € on the Internet) is limited.

The screen can display 3D content, of course, but also 2D content. To play 3D, Acer has joined forces with a leader in this area, the Canadian TriDef offering affordable software solutions for this type of technology. The idea is to see, content is considered then converted into 3D, but 2D content in 3D.

Three areas are covered: pictures, videos and games

To look good, it must be asked. In fact, allowing the hardware and software technology used here, almost no deviation. On a film if it is too low or too high, you lose the 3D effect. Same on the sides. It should, therefore, the correct placement of the screen at an angle of about 120 degrees from the horizontal, as is recommended by a Home menu to start the program TriDef.

With this technology, where the polarized glasses are needed to close one eye and you see the edited image in 2D version.

Technology for converting 2D to 3D video

The SVP group involved in the development of technologies for conversion of 2D video 3D video. Given the recent interest in 3D TV and 3D content scarcity, these technologies can be used to create 3D content from existing 2D content and at a very affordable price.

CRC has developed two complementary technologies for the conversion of 2D to 3D. CRC-i3D technology converts 2D video into 3D video in real time. Technology is a CRC-EGDM editor to refine in order to improve the depth of CRC card i3d to improve the quality of 3D video conversion produces. CRC EGDM technology also creates real-time 3D video from 2D images and to enhance the depth effect.

CRC-i3D: Converting from 2D to 3D in real time

Three-dimensional technology Instant-CRC-i3D, patent pending, is designed to convert the contents of two-dimensional (2D) three-dimensional stereoscopic format (3DS) in real time. This technology consists of two main components: CRC CSDM (depth maps in color or carbon fiber-based) and CRC diBr (rendering based on depth images or RFIP). Figure 1 shows a general model in which the blocks connected by CFCs and RFIP to create a new virtual view required to be generated stereoscopic view.

Key features of CRC-i3D

Technology on the pictures, no time or information about the movement of the base is necessary.

Generating depth maps are based on color.

Ideal product for still images and videos of natural landscapes.

To reduce operating system characteristics of the visual system conflicts between pins depth.

Real-time performance for standard-definition sources with little processing requirements.

Product is easily adaptable for devices with limited processing power, such as laptops,mobile phones and televisions.

3D personal experience, the setting of the importance of the position and depth of the scene in the depth dimension. The technology is integrated into a DVD player for the purpose of testing and demonstration.

Technology CRC CSDM

The first integrated technology CRC i3D, CRC CSDM creates a depth map for an image using the color information as a substitute for actual depth. This card "replacement" provides detailed information needed to convert 2D to 3D to satisfactory (ie, that it produce a convincing 3D effect, but not entirely based on the true depth of the scene). The development of this technology is based on how people perceive, interpret and depth, it exploits the strength of the visual systems based visual content.

The creation of a smart card is replaced using the chrominance component Cr of the YCbCr color space to the depth. We chose this component because it has good features, replaced in order to generate depth maps:

Skin tones are placed at the top, making it possible to always ensure the presence of the main figures in the foreground;

blue skies and green landscapes are placed in the background, creating a deep contrast, the volume in the scene creates;

Shadows of objects within a constant depth, the volume objects are creating.

This approach generally works well, but the use of Cr component has an obvious drawback: the bright red spots or regions are placed at the top of the scene and are clearly visible. For example, the tail lights of cars produced in the night disturbing the scene. To resolve this problem, we have a modification in order to be resolved to increase the depth of these areas moved into the background and will not interfere with the viewing of stereoscopic video.

Technology CRC diBr

The second technology is a CRC CRC i3D diBr. It creates a new virtual image of an original image and the depth of this map. 3 illustrates the general model of the process of RFIP, comprising the steps of:

Pretreatment of the depth map,the transformation of inequality into the depths, taking into account the state of visibility;
Pixels to visualize and contours;

Fill in the empty regions in the new image.

In the process of RFIP, we developed an algorithm for filling the empty spaces.

The tool for creating and editing depth maps CRC EGDM has developed a technology for video content-dimensional (2D) format (3D) (stereoscopic) indirectly convert and do post-processing of stereoscopic images by changing the depth information in the form of depth maps .

CRC EGDM is a graphical interface for modifying depth map . It is used to facilitate the creation of depth maps for custom applications in stereoscopic 3D. 2 shows an example of a depth map obtained after a change. In addition to all the tools to interactively change the depth maps, uses CRC-EGDM in a new way to create color depth card replacement, if none is based there. It represents the histogram of the color channels of the original, the depth maps to produce a replacement or the image gray intensity of the depth map.

Key Features

Specialized interface for editing and adjusting the depth maps.

Immediate overview of 3D stereoscopic visualization.

Advanced patent pending process allows selection of objects or regions of change in the depth maps, depending on the selection and treatment of color.

Practical method applied for a patent for the creation of depth maps replaced if there is no depth chart.

Pretreatment method depth maps patent pending, improves the rendering based on depth images.

Depth gradients to implement flexible and adaptable to specific regions.

Save and load changes and convenient settings.

The application of custom modifications on all images from a video sequence with a single keystroke.

Ideal product for still images and videos of natural landscapes.

Technology Demonstration of 2D to 3D conversion:


CRC-i3D technology can convert video content to two-dimensional (2D) video in stereoscopic 3D (S3D) in real time. For demonstration purposes, this technology as a DVD player for Windows designed and used in an advantageous way parallelism and processing power of hp laptop graphics processing units (GPUs) from NVIDIA. The core technology is a DirectShow filter in C / C + + calling functions is developed for the NVIDIA CUDA architecture. DirectShow filter that as an interface between high-level applications (DVD player) and developed in CUDA functions that give users the parameter generation of stereoscopic images is used to control. In particular, the user generates the in-depth images. Technology is fully integrated into a device for converting from 2D to 3D with integrated:

A Windows PC with an NVIDIA GeForce last (GT980 0 or better) UIN and DVD player

A monitor with 3D

So that's it, we go for the 3D with the key to a lot of questions, new abstruse technical terms and new features as smokers than promising. This is the case of conversion modes 2D-3D integrated some 3D TVs.
