HDTV Mini Camera From Racing Cars

High definition images from racing cars

Sport telecasts could look a lot more realistic to TV viewers in future,thanks to a mini camera being developed by Fraunhofer Institute for Integrated Circuits.It can transmit the view of a Formula One racing driver or ski jumper,all in HDTV quality.

With a size of just 4 x 4 x 8 centimeters,the camera is small enough to fit in cockpit of an F1 race car or on a helmet.According to Stephan Gick, a researcher at the Fraunhofer Institute (IIS), their success was due to factors; the dissipation of the electronics and thus the heat generated was kept very low for the tiny casing and all the components are highly integrated.All camera settings can be controlled through the Web,because the sportsperson can't be the cameraman as well.

Why DSLRs Camera Better Than Compact Camera

Now days the compact cameras is most popular camera.Why? The answers is compact camera actually cheap price than another camera like DSLR camera.So DSLR are more expensive than compact digital camera,but they also have many features better than compact camera.In short reason I bring to you,why DSLR camera better to try.

1.Better Image Quality
With the large image sensors on DSLRs actually more sensitive to light and less prone to noise,while more powerful image processors,create sharper picture with finer colours.It was used by professional photographer.For simple example your wedding picture.It captured by DSLR camera for better and beautiful picture.Are you agree with me? I hope so

2 More Speed
Power on time,shutter lag and continue shooting are much more faster compared to compact cameras.

3.More Option
This camera allow completely manual control of setting such as shutter speed,aperture,sensitivity and white balance and also offer extensive menu options.


4.Upgradeable
Don't like the kit lens?With DSLRs you can just buy another lens to replace it and you can also add flash units,special filters,etc..


5.Better Ergonomics
Although DSLRs are heavier and large than compacts,their sculpted grips and better weight distribution make them more comfortable to hold for longer periods of time

6. Manual zoom and Focus
The zoom ring on the interchangeable lenses make it easy to precisely select a focal length while the focus ring open up more options for experimenting with areas in focus


7.What You See Is What You Get!(WYSIWYG)
The view through the optical viewfinder is very close to the final picture,so it is easier to adjust composition,expose and focus before you snap.


8 RAW format
Beside the usual JPEG format,DSLRs also support RAW format,that mean the original image without any in camera processing for the highest quality


9.Better Auto focus
The smarter auto focus system function more accurately and faster than compact camera,so you won't miss a short from slow focusing


10.Better Flash
You can use the pop up flash to illuminate large area.If that is not enough a separate flash unit will provide more even illumination

So what is your choice ?Is up to you.DSLRs or compact camera,both of it have a advantages,but I refer to DSLRs even the compact camera is more popular.For a small budget better to buy the compact,but if you love the really good quality picture for your own,better to get DSLR one for you:).Ok for further information please read the full review and information about DSLRs from Wikipedia

HP iPAQ rw6800 Personal Messenger

I love the battery life,speedy performance and bright screen,but miss the keyboard of Mobile Messengers

HP took its first steps into the smartphone market with the hw6500 Mobile Messenger,but the Personal Messenger series is distinct in to way: it is more targeted at consumers and does not included a keyboard.

The rw6800 feels more like a generic smartphone than a sophisticated piece of hand crafted hardware.in particular, the silver plastic finish veers towards tacky in place and it is thick at 19mm.This thickness is partly due to a big battery,with a 1,530Ah removable unit inside.That led to some decent scores in our real life battery life test,lasting for around four days between recharges despite some heavy use - HP claims a talk time of five and a half hour and standby of ten days.Another boon is that unlike previous iPAQs,this one can recharge via the standard mini USB port.

It is also fast.A 416MHz processor means Windows Mobile 5 speeds along and whatever task we were performing we could not complain about the iPAQs responsiveness.The screen is similarly impressive,with 240 x 320 pixels and a bright backlight.The flip up cover is another plus,as it means you can shove the iPAQ into a pocket without worrying about scratches.

All this make the iPAQ an excellent device for viewing email. The trouble is started missing the keyboard of Mobile Messengers.Even sending a text becomes a bind when you have to use the mini on screen keyboard or character recognition.

Fortunately,Bluetooth is available for hooking up the optional HP iPAQ BT Foldable Keyboard ( part code FA802AA),headphones or virtually any other peripheral,while Wi Fi is another excellent inclusion.The lack of 3G is drawback but at least EDGE and GPRS are on hand

There is a lot to like here,there's even a decent 2 megapixel camera which takes great picture in good lighting but without an easy way to input information,it falls short a Recommended award.

Panasonic Lumix DMC-LX2

The Lumix's novelty selling point is its 16:9 ratio widescreen CCD.Compared with the 4:3 sensors found on the vast majority of other compact and D-SLR cameras,the CCD is extra width means a greater horizontal resolution and thus wider prints.The sensor is a 10 megapixel unit,part of which can be shut down if you want either 3:2 or 4:3 ratio pictures.This reduces the resolution to 8.5 or 7.5 megapixels respectively.Image quality is generally good,although chromatic aberrations were a problem with some of our higher contrast images.Performance is also slightly lacking - focusing, even in good light,takes around a second for each exposure,which means it is easy to miss shots.Ok it a just short review from me.Knowledge is the first,even is just a short writing from me,Happy reading guys...

Canon EOS 400D A great camera in its own right

Hi readers today I brought to you review about camera ,canon the 'biggest' name in camera digital company I think.I try my best review.... and thanks a lot to Mr William Ong for your permission to me to try your brand new camera,Canon EOS 400D

Today about Canon EOS 400D, so stay with my post if you want further information about it.
Any new camera has to have a megapixel rating to equal its peers,so the 400D is replete with a 10 megapixel sensor,up from the 8 megapixel of the 350D.That is not the only difference,though.It also addresses what's becoming the Achilles heel of the DSLR: sensor borne dust. The front element of the sensor is attached to a pieco electric element and every time the camera is switched off this vibrates for a couple of second in an attempt to shake off any particles.Assessing the systems effectiveness is difficult,but if you have had to go through the nerve wracking process of manually cleaning a sensor with an air blower you will appreciate the help.

Among the other minor changes is the presence of nine point auto focus system,borrowed from its big brother the EOS 30D.The 350D is seven point system was adequate but occasionally struggled the newer system seems a little faster and more sure footed in low light.And while the burst frame has not increased beyond 3fps,the burst depth has been more than doubled from four RAW frames to 10 or up 30 or so JPEG frames.

The body design is almost identical to that of the 350D,which means that the handgrip is smaller than that of most competitors.the only big physical change is at the back the body,where the old 1.8in LCD monitor and secondary LCD settings display have been replaced by a single 2.5in screen.This mean that all camera settings aside from the basic shooting mode,which is still selected by the top mounted rotary control- are set via the colour display.To reduce the distraction of having a screen lit up underneath your nose,there is a proximity sensor beneath the viewfinder that deactivates the screen when you put your eye to the camera


This change has two consequences.First it increases the sluggishness of operation due to the slight switch on delay of the screen.Second,since the battery pack is the same as the 350D and the screen power draining backlight will be on for more of the time,battery life is reduced.On the face of it this is not a problem,since the battery life of all canon models these days is excellent,but it means that if you do start running low in the field you cannot deactivate the screen to save power.The upside is a larger monitor.


Conventional wisdom has it that more megapixels equals more noise,and I was worried that in bowing to market demands for higher numbers,the basic image quality of the 400D would have decreased.Thankfully, that is not the case, and there is no discernible difference in noise perfomance or image quality,it is as excellent as ever.Even at ISO 1,600,where noise is apparent,its quality is closer to film grain luminance noise than the far more distracting chrominance noise that plagues lesser cameras.If you buy the standard kit with 18 - 55mm lens,which has not changed from 350D,the limiting factor is the quality of the lens itself,which tends to produce obvious chromatic aberrations.Replacing it with a higher quality optic will pay dividends.


If you are 300D owner with a large investment in Canon EF lenses,or a first time buyer on a tight budget,the 400D is a worthwhile purchase.
So, be nice information before get one.Bye...
