When light strikes a CCD, it excites the electrons in the chip, creating a grid of charged elements or pixels (for picture elements).
He came up with the 80m figure by multiplying the number of dots, or pixels, in a high-resolution image (about 1m-2m) by the number of surfaces that an imaginary ray of light corresponding to each pixel would encounter as it bounced around a complex scene (say, 50-100).
Top-of-the-line digital cameras, so called megapixel cameras, capture images of a million or more pixels.
Standard 35mm film is capable to resolution equal to 20 million pixels or more.
For cellphones equipped with cameras, the light-capturing sensor chip is a matrix of 1, 000-by-1, 000 pixels or more.
The T28 is equipped with a tiny (to today's standards) rectangular 1.4-inch monochrome screen (101 x 33 pixels or three lines of 12 characters) with a blue-ish green backlight.
Apple says the 2880-by-1800 resolution of the Retina Display has more than five million pixels, or over four times that of the previous MacBook Pro and over three million more than an HDTV.
Well for starters, relying upon vendor, ad network, tier 1 or otherwise, data via pixels is suicide.
The best display on the market today is IBM's Roentgen screen, a 16.3-incher with 200 pixels per inch, or 6.6 times as many as a conventional PC screen.
Or maybe it is the inherent nature of reading pixels instead of print.
They shouldn't be larger than 10Mb and ideally much smaller: around 1Mb is fine, or you can resize your pictures to 1, 000 pixels across.
By contrast an Nvidia graphics processing unit, or GPU, renders graphics by simultaneously hashing out the same problem for multiple pixels: textures, lighting and smooth rendering of shapes flying across the screen.
The capsules are arranged as pixels and electric charges applied to each pixel pull either the black or the white particles towards the top of the capsule (and the opposite colour to the bottom).
ECONOMIST: Electronic screens as thin as paper are coming soon
The new XGA-resolution (1024 x 768 pixels) short-throw projector can be placed close to a screen or white board and achieve a relatively large picture.

When zooming in all the way or when taking pictures at full-resolution (thus revealing the sensor's original pixels) we noticed a bit less detail and a touch more noise.

So, if you've been looking to get all those pixels crammed into your smartphone over to a bigger medium, hit the source or check the details after the break.

Available in 16GB or 32GB, the Kindle Fire HD has a higher resolution screen of 1280-by-800 pixels, Dolby Digital Plus powered speakers, stronger Wi-Fi and better battery life.
As of now, the setup only snaps black and white images with a resolution of 32 x 32 pixels, but there are plans to boost its fidelity by leveraging higher quality photodiodes (or even composite photos).
With pixels on a screen, everyone in the room sees the same dot of white, red or blue.
Traditional cameras use either charge-coupled devices (CCDs) or complementary metal oxide semiconductor (CMOS) chips, which capture images on a grid of millions of pixels.
While most of them are on par with Samsung's other top of the line HDTVs this year (quad core CPU, five panel Smart Hub and apps, recommendations, gesture control etc.), it's differentiating itself with a display based on self-emitting RGB sub-pixels which it claims makes for absolute blacks, pure whites and prevents colors from being washed out or distorted.
