Are Pico Projectors The Best Way To Go For Your Next Projector Choice?

We live in a world where technology and science are constantly changing around us. We are more mobile as a society and, day by day, we are becoming more advanced and efficient in the way we conduct business. We are always looking for new ways to make ourselves a bit more mobile and efficient though. When you go into a business meeting, one of the main focal points may be the images coming from a projector. Projectors are becoming more and more advanced. You can store images and video files directly to these machines and play them right there at the meeting. Whether being used for business or entertainment, projectors are becoming more computer-like as the days go by. As often as we are all on the go, the thought of mobility comes to mind. You can't just take your company's projector home if you want to load something onto it. This is where the pico projector comes in.

I feel that, eventually, pico projectors are going to be the kings of the projector world. Now mind you, my thought process and opinion are not without reasoning. Think about this for a second. Originally we had landlines or "home phones". Now, I'd be surprised if anyone reading this still has an operating home phone that they legitimately use. The cellphone/smartphone has taken its place. It's more mobile. Desktops and laptops used to be the only way to surf the web, listen to music, send emails, and more. Then came the tablet. Virtually every consumer tech company out there is coming out with, or has come out with, their own tablet. Laptops gave us the sense of mobility that the PC didn't. Then came the tablet, which made us even more mobile. PC's are almost obsolete.

The point I'm trying to make here is that we are a society driven by efficiency and mobility. The pivotal changes in technology show the future of what's to come. The cell phone took over the landline. The laptop took over the PC. The laptop is, slowly, being overcome by the tablet. It seems only obvious to me that the pico projector will eventually overcome the standard business projectors we use today.

As businessmen and women, we are always on the go. We're always looking for a way to make our company more successful with less effort and more efficiency. The fact that pico projectors are completely mobile, rechargeable, and can have images and video files stored directly onto them (like their larger, more stationary counterparts) could make more of an impact than we realize.

With the mobility of the pico projector, we are allowing ourselves to always have a backup projector should the meeting room's projector not work. We're allowing ourselves to have our entire presentation in the palm of our hands. We are able to show our presentation whereever we would like. We can store all of our necessary information directly to the device, without having to worry about the flash drive we may have left at home.

Technology is quickly moving along with the needs of a more mobile society. I feel it's only a matter of time before the pico projector takes over in the realm of projectors. You might as well start using them now to put yourself a bit ahead of the crowd.

New Projectors From Hitachi Designed To Work In Bright Environments

We've all used projectors before, or at least been in a situation where we were watching something on a projector screen.  And we know that almost every single situation that calls for a projector also calls for the lights in the room to be turned down or off and for any other external light sources, like sunlight through a window, to be blocked as well. This is primarily due to the fact that projectors aren't quite the same as televisions or computer monitors. They are not bright enough to deliver the same picture quality that other screens can, so other lights need to be eliminated for full picture quality and brightness. However, Hitachi is set to change all of this as the company recently announced that it has developed projector technology that makes video display clearly in brightly lit rooms.

The processing hardware that Hitachi is using is just under 2 square centimeters, which means that the technology itself is capable of enhancing video in everything from security cameras and vehicle camera systems to pocket projectors and home theater projectors. What this technology does is improve the visibility of the projected images without using more light. In addition to that, this technology will also be incorporated into projectors that Hitachi will be launching in the United States and Europe this spring.

Hitachi's approach is focusing more on video processing, which means that instead of processing the entire image as a whole, it analyzes individual characteristics and enhances whatever is necessary. According to Spokesman at Hitachi's Research and Development Headquarters Masayuki Yoshida, "Most manufacturers simply increase the power source for the light projection to improve visibility. Hitachi's technology does not change the power of the light, but it won't make dark regions of an image completely black or lighter regions washed out."

Researchers at Hitachi have developed an algorithm that is based on a model of how the human eye and brain perceive colors and light. This algorithm, known as the Retinex Theory, processes brightness, resolution and color composition while making individual adjustments for each of these factors. As a result, projectors see the enhancement of dark areas in a video without affecting brighter ones, while object outlines are better defined so they appear more distinct. What's more is that the researchers at Hitachi have also optimized the algorithm's processing sequence, allowing it to be efficient enough for commercial applications. Hitachi also developed compact logic circuits that are capable of performing real-time processing at 60 frames per second (fps) for still images and 1920x1200 pixel high-resolution video.

Hitachi Maxwell plans on releasing a total of seven projector models in the United States and Europe, all of which contain the enhancement technology. Hitachi made note to report that all seven of the projectors will feature lumen ratings of 2,700 to 3,600 and will also come with two HDMI digital inputs, allowing you to connect a variety of devices to them. "In recent years, the performance of various display devices has been improved, but it is not sufficient in comparison with the dynamic range of the human eye yet," said another Spokesman for Hitachi, Tomoko Sato. Soto added, "Therefore, visibility enhancement by image compensation has been very desirable. In order to support such needs, Hitachi has developed this technology."

Are LED Based Projectors Going To Become The New Trend?

The LG PG85U Projector is about to hit the market, and it might be a sign of what the future may hold for projectors.

The LG PG85U is completely LED-based and has a 30,000 hour lifespan. Most pressure lamps found in normal projectors are intended to last between 2,000 and 4,000 hours and can be quite costly. With the cost of pressure lamps and the fact that they slowly degrade throughout their life, making the picture dimmer all the time and the picture less appealing, you can understand why one would be excited about an LED-based projector. All you have to do is hook it up, never worry about it again, and know that your picture quality isn't degrading every single time you use it.

There are a few problems with the idea of an LED-based projector though. Yes, they do last longer, a LOT longer. But, pressure lamps are still much brighter than any LED light on the market today. For some people, this may not be that much of an issue. If you are typically viewing your projector screen in a dimly lit or dark room, it may not be a very big deal. For everyday life, and for those using it in a not-so-dimly lit room, this could become an issue. You may run into problems when factoring in screen size as well. Pressure lamps will naturally be able to supply you with a larger screen while still retaining good picture quality. An LED-based projector would probably have a hard time doing that.

With all that being said, LED lights are getting better all the time. The LED lights on the market today are much brighter than they have ever been, even just a few years ago. When this projector becomes officially available to the public, it might completely blow us away. Only time will tell. Either way, I think that LED projectors are a great idea with lots of potential. LED's could be the way that the industry goes, and we may see a lot more projectors like this.
