With the increasingly fierce development of professional HD, the use of various types of high-definition camera and camera products has become increasingly widespread, and megapixel lenses have become one of the focuses of professional use.
HD camera discrimination
To distinguish how the lens is a high-definition camera, in fact it is not difficult, for HD cameras, can use a generic lens claiming a megapixel camera, of course, can also be equipped with a so-called million high-definition camera, can also be equipped with 3 million, 5 million or even 8 million high-definition cameras, but in the case of the same camera, the final display of the picture, the resolution of the lens is still playing a decisive effect.
In terms of practical commodity skill indicators, the center of the megapixel camera lens has a resolution of only 1 million pixels, and the periphery will decay to about 50-600,000 pixels in physical conditions. Currently, the latest mainstream Red Apple HD megapixel camera lens on the market, Red Apple's published skills indicators are generally 70% of the scene radius of the imaging circle, its resolution up to 5 million pixels, 70% of the scene Some areas outside the imaging circle can reach resolutions of at least 2 million pixels.
Currently, there are only a few high-definition camera manufacturers in the lens mall that can do the following: in the 80% radius of the scene, the imaging circle has a resolution of 3 to 5 million pixels, and there are 80% of the imaging circles around the scene. The resolution remains above 2 million pixels. It is not difficult to see, because there will be a big difference between the practice of high-definition and ultra-high-definition cameras and general lenses, but also because the monitoring of the mall presents a lot of manufacturers intentionally mixed lens price positioning, so that the client can not be thus Resolution. However, if these fake high-definition masks are removed, users will be able to understand that the high price on the back of the mall is not necessarily a high-definition product. With the development and maturity of high-definition skills, the lens should not become a barrier to the smooth implementation of the monitoring mall. Therefore, the uniform standard-standard high-definition camera becomes the chief shopping mall mission.
Analysis of the key skills of high-definition camera
The Red Apple HD Mega HD camera has almost the same principle and characteristics as the general camera. However, some people only know the basics of the lenses such as aperture, focus, zoom, shockproof, infrared filters, and motorized lens servo motors. However, some critical skills in the lens, especially the millions of high-definition cameras, are not completely solved. However, these seemingly inconspicuous skills have become the key to the quality of the lens.
Low-dispersion lens (LD, Low Dispersion or UD, Ultralow Dispersion) skills lens skills are generally used for lens color control, improve the color of the photo recovery effect, the use of this skill can make light refracted after a stable spectrum, that is, It means that the color difference of the light after being refracted through the lens is small, and the more the imaging color and the seven primary colors are. LD is generally used in monitoring, and Japanese lens products are used more often.
The lens lens coating (Coating) skill uses this skill to counteract the reflected light of the lens on the lens. The effect is to eliminate ghosts, glare, and light spots that occur when the catadioptric light is resisted. Together, it can reduce the lens reflectance and add lenses. The amount of incoming light (transmittance). This skill is used in surveillance cameras, but there are considerable differences in the skill capabilities of the lens manufacturers. Therefore, in many cases, this can be used as a reference for the selection of the lens. The other thing to say is that the coating of this kind of lens is somewhat. The user only knows whether or not there is coating. It does not know how many layers and what is different lens coating. The lens coating can be roughly divided into nano coating (Nano), Integrated coating, Subwavelength Coating, Multi Coating, Transparation Coating, BBAR Multilayer Coating, HFT Coating, etc. Although many coating techniques are not necessarily required In monitoring, the current surveillance camera uses BBAR and Nano methods. Most of the others are used in DSCs or monocular camera lenses.
Highly transparent raw lens skills (Fluorite FL)
This lens technology is more commonly used in high-end camera telephoto lens and high magnification telescope head, and its other name is fluorite chip lens, characterized by a very low refractive index and LD dispersion, let the lens in the foreground There will be no lens reflection dispersion problems when zoomed in. This type of lens is used throughout the Japanese series of jog lenses.
High-index lens (HRI) skills This lens is special. It uses the lens's special polarization correction technique to make useful corrections to the polarization aberrations that occur when the lens enters the light, and to reduce optical aberrations. This can make the lens volume somewhat The reduction and weight reduction are generally applicable to the digital camera DSC or the monitor On-Bosard board lens, but the essential effect on the monitoring is not high, and is less concerned with the monitoring lens manufacturer.
Multi Focusing (multi Focusing)
This new skill has been successfully applied to the digital camera DSC in 2012. This kind of multifocal imaging technique has a broken application. It means that the lens can have multiple imaging points at the imaging point, and it is not clear when taking pictures in real time. Recording or taking down impressions, after this skill, it is possible to restore the proper focus point on the playback of the impression or the photo photograph afterwards. This has historically broken the proof of the surveillance application, but it has not yet been recorded. A lot of reference to the surveillance camera, trust in the near future; will be referenced to surveillance camera skills. Low-dispersion lenses and aspheric lenses for surveillance cameras are used for such skills.
The above are the use of the lens in the critical skills of the lens to clarify, trust this is some of the skills of the monitoring system users have not touched some of the information, after this elucidation also allows us to obtain more reference information on the lens selection.
Summary <br> <br> on high-definition imaging system, the relevant monitoring system to mature, and many people are not very attention to detail skills. While details determine success or failure, excellent imaging systems will consider more. With the gradual adoption of the high-definition system, the selection of high-definition cameras will be more rational, along with the need to flourish, will in turn promote the continuous promotion of goods.
