Strange recycling myths of Apple DxO One first access type SLR camera

Pictures God and professional photographers have long told us that iPhone can take professional photos. But really wanted to save a digital SLR 5000+ budget is not so easy for most people, so many masters to become the iPhone photography students have turned to a variety of black magic power of science and technology, such as Olloclip and Olympus lenses Air.

Olloclip

Olympus Air

In these two photographic enhancement devices, Olloclip enhanced camera framing effects directly fixed on the iPhone, and Olympus Air is separating independent film unit of the wireless control, there is the vast majority of iPhone photography black technology products such as both types. But both of these devices have some weaknesses, such as the former will lower the iPhone itself has poor image quality, which is sensor size and overall size cannot be taken into account together with a wireless connection between the shooting delay is doomed to be a failed experiment.

But dreams iPhone photographer classmates don't lose heart, foreign camera and lens testing agencies DxOMark is a member of DxO introduced the DxO One iPhone camera enhancement accessories other than Olloclip and Olympus Air fly much, following the announcement on foreign media have sent out. But although products is was bullish, but we also is to in front spit slot about DxOMark, as a neutral of professional equipment evaluation institutions, even is "I line I Shang" (they to has normal mode Xia and SuperRAW mode Xia of DxO One respectively played has 70 and 85 points of high points), price also without so moving's--599 dollars, almost enough buy a Department professional level of authentic digital camera has.

Then again, price aside, from a product perspective, DxO One is still a great product. DxO One after you connect the iPhone may consist of original digital camera, you can look at DxO One as is the digital camera's grip, iPhone can be viewed as LED panels (5000 LED panel)--DxO One two-stage shutter release and camera, iPhone APP regulation take parameters and display photos. In fact, DxO One itself is the set of included light sensitive sensor and lens full camera system, its more powerful hardware capable of shooting more than iPhone fine and complex images.

To summarize, you will find accessories enhance the abilities of iPhone pain point is the following:

Small pictures with his mobile phone, you can't set composite hand SLR

Camera system independent proof Olloclip standing on the shoulder of Giants may get dizzy

Wired connection wireless connection delay critical moments can make you crazy

Olympus and Olloclip Air connection, DxO One design has a good grasp on these points.

First of all, it's small enough. DxO Air very small cross section than the iPhone 6 1/3,the verge thinks it as small as Zippo, carry is very handy, and after iPhone Assembly is not too at first glance.

Secondly, the DxO hardware configuration inverses of One day, we began to read the following parameters: DxO One built-in is a 20.2 million pixel 1-inch sensor, hardware better performance than the iPhone 6 to 8 million pixels, 32mm, F1.8-F11 aperture, shutter time range can reach 15s-1/8000s,ISO 100-51200, two-stage shutter, you can shoot JPG and SuperRAW Mode (similar to the application have been many mobile phone manufacturers took Zhang became one more picture noise reduction to enhance low light effect) pictures. Level overall parameters to be fully digital cameras, DxO only emboldened DxO One iPhone for display.

Finally, the use of Lightning connected the iPhone models were controlled by DxO shooting delay of One very good, snap will have comparative advantages. Although the Lightning interface is relatively small, but DxO connection is quite solid, and can be rotated 60 ° angle adjustment.

DxO One can take a maximum resolution of 5406x3604 pixels photo, video can be 1080/30fps or 720p/120fps.

Ways to buy:

DxO haven't begun spot One being on sale, you need to set aside from the DxO website information intended, the first shipment will be sent only to United States users, will be worldwide shipment. But even the United States there is no specific timetable for the delivery of large (soil) (Howard Johnson) in the reserved mailbox follow DxO to inform.

Everyone is talking about VR GPU manufacturers to do what

On Wednesday (January 13), several waves of technology journalist to arrive in a hotel room near the international trade, the Oculus Rift and experience the latest HTC Vive equipment. Event organizers are not the companies, but a graphics chip maker Nvidia. People familiar with VR knows that this epoch-making technology, demand for graphics computing power has been an order of magnitude. At the upper reaches of the chain of the graphics chip maker, on the VR technology to do what?

First of all, according to the data provided by Nvidia, "immersive VR experience on performance requirements are the General Gaming PC 7 with. "PC game 1080p 30FPS refresh rate and resolution for technical data, while the VR game's actual rendering resolution 1512x1680x2, refresh rate to arrive at 90FPS, will provide a good experience. Otherwise, cannot be guaranteed when moving picture sharpness and picture detail. Secondly, immersive VR experience delay time must be guaranteed, the user head movement to see the feedback time, should less than 20ms. Otherwise, the human brain can occur due to inability to calculate disorders, symptoms are dizziness, lightheadedness, dizziness.

Nvidia Gameworks VR development platform, offers 5 types of graphics rendering technology, namely: Multi-res shading (Multiresolution color), VR SLI (graphics rendering), Context priority (priority context), Direct mode (direct mode) and the Front buffer rendering (buffer before rendering). Next, let me under the science in simple language, and by the time the next time you're talking about VR, but also seems to understand better.

Multi-res shading

The basic principle of this technology is that optical distortion of the graphics rendering and VR helmets together. VR helmet close to the eye, so lens is needed to help the user focus. Because there are lenses, can cause picture distortion, so the picture needs to be compensated.

Distortion compensation of image information required, screen less than that GPU rendering (part lens optical losses, while the human eye to see more clearly the vision Center than at the edges). So the GPU essentially did a lot of wasted effort. Multi-res shading you want to do is, every frame of the screen into multiple parts, retaining more detail and edge retention in less detail. Another way is to compress images, so as to enhance the rendering speed.

VR SLI

Graphics rendering technology principle is very simple, is to support two GPU rendering at left and right eye images.

Context Priority

Context priority is not very well understood. For example, if you turn too fast, new pictures have not rendered, or there is a location picture before, it will cause discomfort. How to solve this problem? Technical experts think a way to artificially insert a frame placeholder that is calculated according to the location. GPU need a separate thread to do the work, and stronger before the next frame appears, thereby reducing the picture delay (or jitter caused by frame).

Direct mode

Direct mode requires Windows operating system support. What it means is that when the VR helmet is connected to your computer before, the computer will not recognize it as an extension monitor and Direct mode can let the computer recognize the VR helmet into a new special display device. The benefits below.

Front buffer rendering

Principle related to direct mode is buffer before rendering. If your computer as normal VR helmet display case, you need to be using a standard two-level buffering mode rendering; identify a VR helmet, you can cross the Back Buffer directly to the Front Buffer, reducing delays.

Another similar programme called LiquidVR GPU maker AMD, also has the technical, but in the high-end GPU market share in recent years leading Nvidia.  Vans phone case

Not years Consumer version of Oculus Rift will launch within a few months

Oculus CEO Brendan Iribe 2014 to be held in Dublin Web Summit, Oculus VR will launch a consumer-level within a few months the Oculus Rift VR virtual reality helmet. Of course, he did not specify the time, saying only that the consumer version name is Crescent Bay, has now completed the majority of the functionality and testing. virtual reality games

In addition, he said the biggest challenge now remains a valid input device. The traditional keyboard, mouse, gamepad or gestures seem to be unable to meet the needs of virtual reality worlds, thus the Oculus in the March acquisition of Carbon Design, a company that designed the Xbox360 joypad. virtual glasses

In addition, Oculus has developed from 75 to more than 200 people, there is an independent research and Development Department.

Mobile phones have 4 k screen results will most benefit of virtual reality

Sharp's recently issued a cell phone with a 5.5-inch 4K display, which makes us think smartphones will have more new high lethality. Nevertheless, such high pixel products do in fact have it: make more realistic virtual reality products.

No doubt, sharp's small IGZO ultra high resolution display will use Smartphones, such as strong flat-screen mobile phones iPhone 6 Plus. (It was reported that sharp is one of Apple's suppliers of screen) and market calls for 4K display is clearly very high: the more, the quality is getting better and better!

But the reality is not so. Sharp's latest product 3850x2160 resolution, which has 806 pixels per inch (PPI), almost twice the iPhone 6 in pixel Plus and Galaxy Note 3 on the screen, and on both phones to distinguish with the naked eye pixels is less likely.

In regular distances, you can only recognize half of the 5.5-inch 4K display pixels, in most cases, the majority of people, most applications, most cannot be identified with environment high definition and resolution.

In other words, we don't need such high resolution.

This is not to say that 4K displays can retire the rivers and lakes. It also has some incidental advantages, one of which is 4K can easily become full HD content. However, this advantage has failed to convince us with a 4K screen, especially when you take into account the electricity consumption. In addition to the battery-benefits, and what are the other benefits?

Ahem, or calm down a little. Anyway, the main target beneficiaries of sharp 4K screen is not a smart phone.

The virtual world

If you haven't played the virtual reality devices, such as the Oculus Rift or HTV Vive, you do not worry, this does not mean you are out. Have been developed for a number of years, and prospects are good, but still not on the current market of high-end head-mounted virtual reality display. Secondly, you need to know, no matter how exciting you read first-hand accounts of publicity materials, these devices are much improved.

5.5-inch 4K 806PPI display can accelerate this process.

Brian Blau is the consumer technology analyst at Gartner research. Virtual reality is one of his subjects. He said virtual reality head-mounted devices will benefit from the application of super high resolution screen, this benefit will be very obvious. Paul Frank iPad Air 2 Case

"If the screen resolution is not high enough, it is easy to see the individual pixels," Blau said. Most virtual reality head-mounted device using optical lens elements on the screen larger, shortcomings are magnified, and easier for people to see the pixels. Virtual content created by two separate images, this makes the final image is not clear.

Therefore, high resolution screen means that people no longer see the individual pixels. Duang sound, virtual worlds are very clear. People couldn't believe it.

Although from a Smartphone-based headset such as the Google Cardboard, to fully integrated devices such as HTC and Oculus Rift Vive, 4K screen, but a separate headset should be the biggest beneficiary. They are often connected to the computer, without worrying about battery life issues, can also make use of powerful processing power of computers. New sharp screen before they reach the mass production next year, the Smartphone industry will see tremendous development, may be able to maintain quality 4K virtual reality experience for a long time.

So we don't have to worry about 5.5-inch Smartphone display pixels high cannot recognise. If you look at virtual reality, you have grounds for excitement. If virtual reality is to be welcomed, it must become more realistic. Sharp 4K screen and other inventions which will come later, and will promote the development of virtual reality head-mounted devices in the future. Paul Frank iPad Air 2 Case
