COMPUTER IMAGE PROJECTION OR DIGITAL IMAGES


Computer image projection

the process of projecting computer generated materials using liquid crystal display (LCD) projector.


Two types of projector

DLP (Digital light processing)

it is been developed by Texas instruments, its clearer and more vivid

pictures compared to the LCD.

LCD (liquid crystal display)

requires a complete darkened room for optimal projection.


Integration Where it yields real benefits

in providing dynamic or interactive presentation.and its difficult to justify simple presentation.


ADVANTAGESIt is possible to project all which

appears in a computer screen.Presentations using LCD projectors are

more professional lookingA vast capacity of images for

projection can be stored in the computers.

Displays can be changed after or even during the presentation.


ADVANTAGESRandom access - Digital images stored on

discs can be rapidly and randomly access.Durability - The discs are very durable.

Fingerprints do not interfere with the quality of the projected visual, as is the case of slides and filmstrips.

Storage capacity - All the discs store thousands of colorful images at your fingertips.


ADVANTAGESPortable - Digital discs are extremely

portable.Less storage space - It would require

67580 slide trays to store the 54,000 still images on a single videodisc and on the computer.

Image choices Interactivity


Limitations oLack of brightness – the room must

be darkened more than in an overhead projection

oLegibility - oExpense – LCD projectors are costlyoLow resolution of LCD projectors

may affect viewing conditions


MOTION MEDIA

use of both auditory and visual senses at the same time. It is an effective device in arousing the pupil’s interest, in recreating the past and in bringing the outside world into the classroom.
