pixels

Pixel resolutionThe term resolution is often used for a pixel count in digital imaging, even though American, Japanese, and international standards specify that it should not be so used, at least in the digital camera field.[1][2] An image of N pixels high by M pixels wide can have any resolution less than N lines per picture height, or N TV lines. But when the pixel counts are referred to as resolution, the convention is to describe the pixel resolution with the set of two positive integer numbers, where the first number is the number of pixel columns (width) and the second is the number of pixel rows (height), for example as 640 by 480. Another popular convention is to cite resolution as the total number of pixels in the image, typically given as number of megapixels, which can be calculated by multiplying pixel columns by pixel rows and dividing by one million. Other conventions include describing pixels per length unit or pixels per area unit, such as pixels per inch or per square inch. None of these pixel resolutions are true resolutions, but they are widely referred to as such; they serve as upper bounds on image resolution.




According to the same standards, the number of effective pixels that an image sensor or digital camera has is the count of elementary pixel sensors that contribute to the final image, as opposed to the number of total pixels, which includes unused or light-shielded pixels around the edges.



Below is an illustration of how the same image might appear at different pixel resolutions, if the pixels were poorly rendered as sharp squares (normally, a smooth image reconstruction from pixels would be preferred, but for illustration of pixels, the sharp squares make the point better).







An image that is 2048 pixels in width and 1536 pixels in height has a total of 2048×1536 = 3,145,728 pixels or 3.1 megapixels. One could refer to it as 2048 by 1536 or a 3.1-megapixel image.



Unfortunately, the count of pixels isn't a real measure of the resolution of digital camera images, because color image sensors are typically set up to alternate color filter types over the light sensitive individual pixel sensors. Digital images ultimately require a red, green, and blue value for each pixel to be displayed or printed, but one individual pixel in the image sensor will only supply one of those three pieces of information. The image has to be interpolated or demosaiced to produce all three colors for each output pixel.

When I went to buy a TV with Ahmed, I saw this.  When I went to BETT a chap on the HP stand told me about superfast boot ups with a solid state drive..

I also talked to the guy from Bedford who has softaware to run two stations from the same computer.  He mentioned a particular NVidia card , but I'm not sure if I can find the details.  (this review shows that you can get it in the US for same price in dollars as you would pay in pounds. ($1899 in US and 1999pounds in(with VAT).  That difference @ excahnge of $1.60 to the pound id 800 pounds. For that you could fly to New York for a weekend!!

Jan 18 2011 - The Toshiba Qosmio X500-Q930S is a large 18.4-inch gaming laptop computer with a new Intel 2nd Generation Core i7-2630QM quad-core processor. This Sandy Bridge processor is fast, as are the two 500GB 7200RPM hard drives. While the notebook is very heavy, it can be used as a desktop replacement with excellent gameplay utilizing an NVIDIA GTX 460M 1.5GB GDDR5 graphics card. Unfortunately, the Toshiba X500-Q930S only supports 8GB of memory. However, this attribute can be overlooked due to the overall value and extra features.

Review - Toshiba X500-Q930S 18.4-Inch Gaming Laptop Computer

Image Courtesy ToshibaSo you're transitioning from your beloved gaming desktop to a more portable solution, but hate to be confined to a 15-inch screen? The Toshiba Qosmio X500-Q930S features a large 18.4-inch TruBrite LCD display that supports 1080p 1920x1080 resolution. This high resolution is excellent for gaming battles.



Visually, the Toshiba Qosmio X500-Q930S offers the same red and black glossy chassis as seen in previous models. Fortunately, the colors aren't overly distracting and create a unique design compared to mainstream laptops.



Processing power comes from the recently launched 2nd Generation Intel Core i7-2630QM quad-core processor using the Mobile Intel HM65 chipset. The CPU has a stock speed of 2.0GHz and 2.9GHz with Turbo Boost technology. This Sandy Bridge processor is a powerful chip and is suitable for a laptop in this price range ($1,899 MSRP).



The Toshiba Qosmio X500-Q930S also has an abundance of memory - 8GB of DDR3 1333MHz RAM is equipped in this laptop. Unfortunately, the system only supports up to 8GB with two main memory slots. While 8GB of memory is plentiful for gaming and working in a variety of applications, such as Microsoft Office, capping memory at 8GB impedes future upgrades.



But since the Qosmio is built for gaming, you're most likely wondering how good the graphics are. The Toshiba Qosmio X500-Q930S features the NVIDIA GeForce GTX 460M video card with 1.5GB of GDDR5 discrete graphics memory. The GTX 460M has 192 shaders and supports DirectX11 for smooth gameplay in the latest games. However, since the system rings in at $1,899, some gamers would prefer the ATI Mobility Radeon HD 5870 (seen in the ASUS G73JH) for slightly better performance in demanding games.



Since the Toshiba Qosmio X500-Q930S is a high performance gaming laptop, storage space must be fast and spacious. The Qosmio doesn't disappoint with two 500GB 7200RPM hard drives. It also makes a great multimedia machine with a Blu-ray drive and HDMI output, so you can watch your favorite Blu-ray movies on a compatible HDTV. Sound quality is also good with built-in Harmon Kardon speakers.



Unfortunately, with an abundance of screen real estate and powerful components comes added weight. This system is very heavy, starting at 10.1 pounds. Don't count on carrying this notebook around for long periods of time unless you're looking to build some muscle. And while battery life is enhanced with a 12-cell pack, don't forget that gaming for a prolonged period of time requires plugging the system in.



Overall, the Toshiba Qosmio X500-Q930S is a nicely equipped desktop replacement. Gaming is a pleasurable experience thanks to the high resolution screen and decent graphics card. While the weight and price are turn-offs, the new Intel Sandy Bridge Core i7-2630QM CPU is one of the top processors on the market today, and the NVIDIA GTX 460M graphics card offers smooth gameplay. Small details, such as including Windows 7 Professional versus Home Premium are also excellent additions to the overall value.

5.0 out of 5 stars Superb! A concise starter guide, 5 Aug 2010

By Jonny IT Guy - See all my reviewsThis review is from: Learning PHP, MySQL, and JavaScript: A Step-by-Step Guide to Creating Dynamic Websites (Paperback)

Another excellent member of the O'Reilly book range, this is a superb start for learning the ins and outs of PHP, MySQL and Javascript. It doesn't weigh the reader down with a lot of uneeded information and sets a nice pace for easy learning. I'd already had a small amount of experience in working with PHP and MySQL in the past but within a couple of hours of picking this up I had applied some newly learnt coding practices to an application I was working on.

5.0 out of 5 stars Perfect Book For Both Beginners & Professional, 9 Oct 2010

By Omar Venture (UK) - See all my reviewsThis review is from: Learning PHP, MySQL, and JavaScript: A Step-by-Step Guide to Creating Dynamic Websites (Paperback)

I am quite familer with many of the O'Reilly book range some of which were excellent and some a bit to advance to understand... but i can happily say this book was excellent without a doubt it was very easy to understand and detailed at the same time, it a perfect book for anyone who want to learn PHP, MySQl & JS.

I actually brought this book to code wordpress themes in PHP and after 2 week of reading this book thats what i did and it also shows the power of combining PHP, MySQL & JS together which was really impressive.

Comparison: i my opinion this book excellent quailty is one of many reasons to buy the book, the other being using it as "Future Reference" which in many ways saves you money compares to buying a DUMMIES book which only shows the Basic elements of PHP ect. so wheather you turn from Beginners to pro this Book is for you!

5.0 out of 5 stars A great read for beginners, 26 Sep 2010

By Anthony Collins (London, UK) - See all my reviews

(REAL NAME) This review is from: Learning PHP, MySQL, and JavaScript: A Step-by-Step Guide to Creating Dynamic Websites (Paperback)

I'd previously bought "Learning PHP & MySQL" from O'Reilly and found it confusing and hard to follow.


This one was completely different. I loved it. It explains things clearly and really helped me to understand. Maybe different people appreciate different styles, but this is the one book that really helped me get to grips with PHP and MySQL (still struggling with Javascript!)

5.0 out of 5 stars Great for both beginners and amateurs!, 19 Jan 2010

By Adrian Von Gegerfelt "The New Son of London" (Stockholm, Sweden) - See all my reviews

(REAL NAME) This review is from: Learning PHP, MySQL, and JavaScript: A Step-by-Step Guide to Creating Dynamic Websites (Paperback)

I had general knowledge in PHP from modding and experimenting with Wordpress themes. HTML and CSS wasn't new to me - I work as a web designer, but I'm not perfect with javascript. SQL scared me.

This new O'Reily book filled in my blanks - gave me facts and tips about PHP developing and more self confidence in playing around with MySQL in PHPmyAdmin.

I'd say the things you need to be a great PHP web-developer are experience in HTML+CSS, a great idea, and this book :)

5.0 out of 5 stars Best Read For All Level Of Programmer, 27 Sep 2010

By metallicrazy - See all my reviewsThis review is from: Learning PHP, MySQL, and JavaScript: A Step-by-Step Guide to Creating Dynamic Websites (Paperback)

I am a third year student at university studying computer science and I read this book over the summer to refresh my memory and solidify the skills I have learned from the last two years. This is one of the best books I have read on the subjects and I am always using it for quick refernce when coding.

I would and have recomended this book to several of my friends. Help other customers find the most helpful reviews
