None of the lenses are absolutely perfect and need to be addressed and improved through software or firmware upgrades, which involves lens correction. The lens correction of the SLR camera is mainly peripheral light correction, chromatic aberration correction and lens distortion correction, the peripheral light is being taken in the camera, and the chromatic aberration correction and lens distortion correction need to be done by random software.One, p

. By detecting and supplementing the actual scene, the wearer gets the information that the real world cannot get quickly, and because the interaction is more natural, these virtual items are more realistic.Third, the future of augmented reality in the future, we wear glasses or contact lenses will again change our communications equipment, office equipment, entertainment equipment and so on; In the future, we no longer need computers, mobile phones a

Recently, Ajax is very popular.ArticleThere are three, three, and four about Ajax, and they have been like this for a long time. It's just a way to improve the user interface. As a result, I mentioned the height of the framework and felt a little uneasy, so I ran the risk of being hot by steam and jumped out to pour cold water on the hot iron block of Ajax. What Is Ajax, that is, packaging of JavaScript, xhttprequest, DHTML, and other technologies. I have carefully studied the use of ajaxpro.

I believe most people often see three-dimensional images through red-blue or red-green glasses. The use of red-blue or red-green glasses in a variety of ways of three-dimensional image observation should be the lowest cost and the easiest way to achieve, although this method has the disadvantages of poor color reproduction and eye fatigue, but it still has good results and is worth trying.The main principle of viewing a three-dimensional image is to let the two glasses respectively watch two pic

is too large, the reflector or flashlight should be used to fill the light. Otherwise, the exposure of the subject will be seriously insufficient and it will be too dark, of course, the Silhouette effect can also be captured. 4. How to make it clearer This problem must have existed for a long time and is related to many factors. A good lens and ox's head are better in imaging and resolution. Each time we use 85mm f1.4d, we all scold this header for being expensive and feel this header value

1. The magnification of the dual telecentric lens is independent of the position of the analyte and the position of the image plane. In the object side telecentric lens, the magnification is a constant, corresponding to a fixed image plane. 2. Aberration of the lens: spherical aberration (symmetry): Aspheric lens instead of spherical lenses, large f, small light-through aperturePoor (asymmetric): Use a smaller f, larger light aperture3. Line scanning

Well, the above information is small knitting to all photographers to bring the details of the Canon EOS m camera lens can be replaced by the issue of the full content of the solution to share, you see the photographers here, small knitti

professional cameras. This viewpoint is biased, and there are three bias points. 1. Flickr is the world's largest online database. It not only provides image storage functions, but also counts rankings of popular cameras. Figure 4 shows the ranking of the most popular cameras on the Internet in May 12, 2011. IPhone 4 is currently the second most popular camera. Obviously, the market share of traditional cameras is being eroded by mobile phones represented by the iPhone, and the speed of these m

Let's first cite an example:In our daily life, the glasses we call are mostly framed glasses, but when we lift contact lenses, we think about whether it belongs to glasses. The answer must belong to it. The contact lenses and glasses here are the is-a relationship.In the object-oriented programming process, we are creating multiple classes. For example:China:｛｝Shandong Province:｛｝Jinan city:｛｝In the process

To enrich the image, photographers put a variety of special films in front of the camera's lens, so that the photographs included the special effects of the lenses added. is called "Color filter". The idea of special lenses extends to the computer image processing technology, then produces "the filter (Filer)", also called "The Filter", is one kind of special image effect processing technology. Generally,

The construction of the racket often appears to tilt and deform. How to correct? With PS simple operation can be done! 　　How to eliminate the tilt effect of the building? Q: I used to take a lot of pictures of high buildings, but these pictures are obviously deformed. The top of the buildings in these photos are converging inward, how can I avoid such a phenomenon in future filming? A: The most straightforward solution is to pay for a moving-axis lens (also known as a perspective corre

The computational magnification is essential for JavaScript Magnifier. In a complete magnifying glass structure, a total of 4 objects, original images, thumbnails, lenses, and windows are linked to the magnification. The position of the lens in the thumbnail is actually the display of the window to the original image, so they have the following relationship. magnification = Original image/thumbnail = window/lens The magnification is generally great

processors and memory in them. While Google redesigned its smart glasses, other tech companies are also developing their own smart-glasses products. The waveguide lenses, such as Vuzix and Nokia, look more like ordinary lenses, but can display 720p images. In the near future, these wearable display devices will become as popular as wearing a pair of sunglasses. Soulaiman Itani, the co-founder and chief s

highlights. Using surround exposure to take multiple photos under different exposure values, later in the image processing software, they are combined to enhance tone and quality. 　　 3. Light When shooting food, the natural light from the window is the simplest and the best. You can put food dishes in the vicinity of the window, so that the food enveloped in the indirect sunlight. If the light coming through the window is direct, try masking it in front of the window with a thin

lower sensitivity. Four, the lens path has the pollution, causes the light not to arrive smoothly. The reason is that the working environment is poor, there is pollution, long time, dirt attached to the light-emitting tube, photosensitive tube, lens and reflector surface, blocking the path of light access to light path. The treatment method is to use cotton ball dip anhydrous ethanol scrub, scrub parts including light-emitting tube, lenses and mirro
