Digital Imaging Explained

The digital image that is created byrepparttar CCD is huge. It's far too big to be easily stored inrepparttar 116103 relatively little amount of storage space that's available to a digital camera. Accordingly,repparttar 116104 camera's computer compressesrepparttar 116105 image to make it smaller.

There are two basic methods for achieving this compression. The first method takes advantage of repetitive patterns inrepparttar 116106 image. For example, if you are taking a picture of an airplane that is flying inrepparttar 116107 sky, a lot ofrepparttar 116108 picture will be a chunk of blue sky. The camera recognizes that there are multiple parts ofrepparttar 116109 image containingrepparttar 116110 same digital information, so it only records a small piece ofrepparttar 116111 sky. Then it simply creates a map to tell it whererepparttar 116112 rest ofrepparttar 116113 sky belongs. Whenrepparttar 116114 picture is ultimately displayedrepparttar 116115 sky appears exactlyrepparttar 116116 same as it did inrepparttar 116117 original image when it was first captured. The only difference is thatrepparttar 116118 overall storage requirements were reduced thanks torepparttar 116119 camera's clever mapping techniques.

The other method uses a procedure called irrelevancy. This methodology automatically removes digital information that is not visible torepparttar 116120 human eye such an infra red light.

Digital imaging is amazing yet we have only started witnessingrepparttar 116121 revolutionary changes that are yet to come.

Most titles give yourepparttar opportunity to connect directly to a pre-arranged player or to find an available player through available message boards.

Peer-to-Peer software may likely becomerepparttar 116102 dominant chess software inrepparttar 116103 future and replace chess servers asrepparttar 116104 preferred method of playing chess onrepparttar 116105 computer.

Chess Software Database

Chess software databases are like holdingrepparttar 116106 sub total ofrepparttar 116107 world's chess knowledge on your local PC. Most programs offer thousands of past grandmaster games for you to review either in text or video format. There are endless opening, middlegame, and endgame strategies. You can read annotations and some titles even have photos ofrepparttar 116108 world's grandmasters.

Some chess software databases come with built-in chess software that lets you play outrepparttar 116109 games that are inrepparttar 116110 database and even allowrepparttar 116111 database to analyze your game.

Prices are low and chess software databases make a great learning and analytical tool.

Computer vs. Computer Chess Software

These chess software programs pit computers against computers using an Internet or LAN connection. They are good learning tools in some ways but you shouldn't read too much into their strategies. These chess software programs can't actually "think" like humans do. Theirs is a mathematical world where moves are calculated according to a set of formulas that allow it to determinerepparttar 116112 "best" move based upon all possible moves atrepparttar 116113 moment.

In spite of their "non-thinking" processing, chess software has evolved to become a formidable opponent even forrepparttar 116114 grandmasters.

In my opinion nothing beats a head-to-head game with a living breathing opponent who is seated a few feet away from you onrepparttar 116115 other side of a real chessboard. However, I realize that today's lifestyle does not always allow usrepparttar 116116 luxury of pre-planned leisure time and they have to pick up a game whenever and wherever we can. With that it mind, you should pick yourself up some chess software for those times when a human in he same room is not an option.

Michael is fascinated by all aspects of the game of chess. - Find more at htpp://
