Data Compression - A method of reducing the size of files, such as image files, by representing the sets of binary numbers in the file with shorter string that conveys the same information.
data compression
The process of converting data from one format to another format that is physically smaller in size. The same logical information is stored using less physical information.

Data Compression: Reducing the amount of electronic "space" data takes up. Methods include replacing blank spaces with a character count, or replacing redundant data with shorter stand-in "codes".
Data compression
Digital cameras don't have the massive amounts of storage a computer does, yet they create files that can be quite large. Because of this, the camera compresses used, the better the image.
Data compression techniques that reduce some detail of a digital image are described as being "lossy." Most video compression techniques utilize lossy compression.

Back in the early 1950s some very brilliant men designed an analog data compression scheme which we know today as color TV. It allows the transmission of the three discrete Red, Green and Blue (RGB) color channels in just one TV channel.
There are two general types of data compression: lossless and lossy. Lossless compression has the advantage that no data is lost. So, lossless compression does not degrade the quality of images.
Entropy coding is a special form of lossless data compression. It involves arranging the image components in a "zigzag" order employing run-length encoding (RLE) algorithm that groups similar frequencies together, inserting length coding zeros, ...
Standard method of image data compression used to reduce the file size of digital images. It's known as lossy compression because there is a permanent loss of some data during the process.

The best camcorders use better data compression (codecs) and offer higher resolution / frame rates than most stills cameras. 3-CCD cameras are still the benchmark for professional video.

Because they save all of the pixel information in data compression, TIFF files are much bigger than JPEG files. As a result, TIFF files require large amounts of memory to store images.
To make the most of their storage space, almost all digital cameras use some sort of data compression to make the files smaller. Two features of digital images make compression possible. One is repetition. The other is irrelevancy.
PNG - Abbreviation for Portable Network Graphics, a format for storing bitmapped images, employing lossless data compression and supporting transparency. PNG was created to replace the GIF format as its use does not require a patent license.

(Portable Network Graphics) pronounced ping. A new standard that has been approved by the World Wide Web consortium to replace GIF because GIF uses a patented data compression algorithm. PNG is completely patent and license-free.

At a resolution of 300 dpi, you would need more than 8 megabytes to represent a single 8½ by 11-inch page using 256 shades of gray. This can be reduced considerably through data compression techniques, ...
