Learn Digital Photography – The Megamyth megapixel explained in 4 steps

Saturday, August 28th, 2010

So you’ve just returned from the camera shop with all the information that you need more megapixels your camera. Your current compact camera has 8. 1 megapixel and the seller tells you that you need to upgrade to the 10 new ones. 1-megapixel model to really improve your pictures. Rubbish! Here’s why you do not need de.Parce that digital cameras are often classified according to their number of megapixels, the megapixel rating of a camera is often used as a measure of image quality. This is a totally wrong concept and myth. There are a number of factors that determine the quality of a megapixel camera and is really an insignificant part. 10. 1 megapixel compact camera with low price and 10. 1 megapixel digital SLR and dear to the Antipodes. For comparison, they mean nothing. If they served something so why such a big difference in their prices. The price difference between a compact and an SLR should immediately tell you that there are other factors to take into considération.Voici what really matters: 1. Quality of the lens caméraIl costs a lot of money to build a quality lens with high quality glass. If the device is cheap, it means the lens is cheap. Even if it had 36 million pixels in the quality of your image is going to mean. Camera manufacturers can not afford to put quality glass in a camera of bad quality. Even with digital SLRs that have interchangeable lenses, the difference between entry-level lenses and lens Pro is enormous, measured in thousands dollars.2. Quality camera construireLes parts that go into building a good quality digital camera costs a lot of money to develop and then the camera will cost more. The cost difference between plastic or aluminum and high quality magnesium alloy is large. This is more so with digital SLRs. When comparing how a shutter button or dial feels a entry level SLR, you will feel a considerable difference is still reflected in the prix.3. Quality of capteurComment manages your sensor light and noise that results depends on the quality and construction of the CCD or CMOS sensor and ISO rating. Try taking a picture with lots of shade and you will see that in the darkest parts of the image are patches of color and a more granular. Is the noise. The more expensive cameras will have much less noise, or sometimes no sound at all compared to the less expensive compact cameras. This degrades the image quality, even with a good objectif.4. Quality of processeurChaque device has a computer chip called the processor that supports the digital information received by the sensor and transforms them into an image. The way they are treated affects the speed and overall quality of the image. The more powerful and complex processor for the best image quality and of course plus the cost of the device. Again, the more megapixels processed by a processor of low quality will continue to provide an image of low qualité.Il is so easy to use one aspect of a camera to judge the quality of a camera and c ‘ is that manufacturers and sellers have done. It is much easier than to explain a number of complementary factors, but makes the explanation of a myth. We need almost quadruple the megapixels of a camera sensor to an obvious improvement. Even just doubling megapixels does give you a subtle change in quality. And this will again only really play a role if all other factors are also of augmenté.Alors, how do you know what to buy? The answer is of forums and review sites. See what reviewers have to say and then read the forums and hear what people who bought the camera, you can have dire.Utilisez your natural instincts and you’ll know when a person derives sales the dressing. No manufacturer can afford to sell high quality at low prices. This is why many manufacturers sell you a digital SLR lens comes as a kit with the camera and not a single high quality, reduce coûts.Ainsi, the bottom line, your instincts. When someone wants to sell you a BMW or a Mercedes at a price Suzuki alarm should sound.

With the ability to capture full HD video clips at 1920 x 1080 resolution, Canon EOS 5D Mark II Digital SLR offers a 21. 1-megapixel full frame 24 x 36mm CMOS sensor, DIGIC 4 imaging processor and significantly lower noise, with ISO sensitivity range is from 50 to ISO 25600. “The anticipation surrounding the launch of this camera model has exceeded our greatest expectations, and we believe our loyal customers will be impressed by the level of innovation and features built into the new EOS 5D Mark II Digital SLR . Once they thechance to experience the camera, we believe they will agree it was worth the wait, “said Yuichi Ishizuka, senior vice-presidentand general manager, Consumer Imaging Group, Canon USA Among the many advances in the new Canon EOS 5D Mark II camera is the exclusive property of the Company’s DIGIC 4 Imaging Processor that powers fast the conversion device 14-bit analog-digital shades of soft colors and exceptional gradation. The Canon EOS 5D Mark II Digital SLR offers a full frame 24 x 36 mm, 21. 1-megapixel CMOS and continuous shooting at 3. 9 images persecond (fps) for an unlimited number of full-resolution JPEGs to the capacity of the memory card or up to 14 RAW images in a single burst when using a UDMA CF card. The unit includes a 15-point Autofocus (AF) sensor with nine selectable AF points plus six Assist AF points other (three center AF points sensitive to f / 2. 8 lenses) with enhanced light source detection and AF for microadjustment autofocus performance more. The EOS 5D Mark II camera also features a large, clear 3. 0-inch Clear View LCD screen with 920,000 dot / VGA resolution, four times the number of pixels of the EOS 5D camera 2. 5-inch screen, for enhanced clarity and color when viewing images. The new camera is equipped with a high performance, high-magnification optical viewfinder providing 98 percent coverage, giving a new dimension to the adage, “what you see is what you get.” Professional photographers will also enjoy the building aspect 150,000 cycle durability of the EOS 5D Mark II. Canon, the first company to introduce a full-frame digital camera, has improved the EOS 5D Mark II Digital SLR newly developed full-frame CMOS image sensor. Using Canon’s patented technology, the Company has reduced noise and expanded the sensitivity of the CMOS sensor ISO 25600, which is three full stops higher than the ISO 3200 limit of the original EOS 5D. Although the individual pixel dimensions of the EOS 5D Mark II are the same as 21. 1-megapixel CMOS sensor used in the SLR EOS-1Ds Mark III Digital, the new sensor incorporates an improved output amplifier and a more advanced color filter that improves light transmission while retaining excellent color reproduction.

Leading technology megapixel CCTV

Thursday, April 29th, 2010

The CCTV Market crossed an evolutionary step forward with the creation of megapixel IP cameras, perceived by many as the future of the CCTV market multi-megapixel (MP) IP cameras are now available that offer a huge jump in image quality compared to conventional surveillance cameras. Example A megapixel surveillance of the most compelling advantages surveillancesystems megapixel CCTV is their ability to capture not only the situational awareness an overview of what is happening but also fine detail that can be used for reading plate and identification. The combination of situational awareness and detail allows security operators to respond more quickly and reduce the time of the survey, all with a greater likelihood of prosecution and conviction. The images below illustrate how the HD megapixel video surveillance systems can take full situational awareness and fine details. A standard camera would be able to display this image and should then be zoomed to show detail using a PTZ and then lose the rest of the image that is out of sight. With this detailed megapixel cameras can be expanded, while the still recording the whole situation. Detail1: Detail2: Detail3 Electronic Pan Tilt Zoom (ePTZ) Any security Nion megapixel includes digital pan / tilt / zoom ePTZ. ePTZ has been developed to solve the problems with traditional mechanical pan / tilt / zoom devices. Mechanical devices let users redirect the camera but only record what you have zoomed in on. This can be a problem when there are more than one object in the scene or if nobody controls the camera. Security Nion Electronic Pan / Tilt / Zoom ePTZ lets you move a large virtual image using a small viewing window. As it is virtual, you can always save the whole scene in the multi-megapixel resolution, even if you can be digitally “zoomed”. This means that you never miss a thing. ePTZ also saves bandwidth. In many cases you do not need to display a multi-megapixel image when you go to the video on a WAN or Internet. ePTZ Nion security allows you to display an image much smaller that shows the entire field of view in a small window. If you see something that interests you, just digital zoom and resolution of security Nion multi-megapixel comes in. When you zoom in, ePTZ this in more detail if you do not suffer the distortion typical with other products.
