The film is taken from a reel above the projector and passes in front of a very bright bulb. Each frame is held in place for approximately 1/24 seconds. The image is projected… into a screen.
A projector simply projects images onto a wall or projection screen. Projectors are typically used to increase the image size for viewing by audiences. Projectors come in a va…riety of sizes, normally measured in Lumens which is the brightness of the light. This brightness will determine the size the image can project and the distance the projector can be from the screen. Slide projectors use light to project images from 35mm slides. Digital Projectors use light to project images from computers and DVD players.
There are two types of projectors: The two types of projectors are LCD and DLP. LCD: LCD stands for Liquid Crystal Display. The way this places an image on a screen is fa…scinating and not nearly as complex as you might imagine. A bulb is set up to shine a fairly powerful light through a prism. The prism splits the light into its component colors and these are sent through small LCD screens. The screens themselves are sent signals to allow just so much of the light through at specific pixel locations. The light is then beamed through a lens onto a screen where the images can be seen by the human eye. DLP: DLP, or Digital Light Processing is a bit more complex. This time the light is shined through a spinning color wheel onto a chip that is mounted with hundreds of thousands of tiny mirrors. The mirrors are turned off or on by electronic impulses according to the need for the color at that moment. Even though only one color is shown at a time, one color follows another so quickly that the primary colors seem to blend into the appropriate color. The image appears to be constantly lit, when in fact small parts of it are constantly flickering. This technology was developed by Texas Instruments and is based on an older technology that was used for color television in the 1950s.

A video projector takes a video and reflects it off a mirror. The video is played on a screen that is a solid color preferably white.
A projector is a machine that shines a reflection of an image or text onto the surface in front of it. Example: The music teacher shone the song lyrics onto the wall for the c…hildren to see via the projector
i know because enter the data
regarding throw of image these can be divided into three classes i.e medium range, short throw(st)and ultra short throw (ust) and regarding working it has two basic types i.e …3lcd and dlp. 3lcd is good (4-5 hr) for continuous prolong work, with comparatively poor resolution, whereas dlp provide high resolution but meant for short use i.e 45-60 min than rest needed coz it dont have fan cooling system (answer by shahid jamal) email@example.com
Projecters show a larger version on a screen or blank wall of what you are either teaching or watching. For example when i went to my friends house she has a projecter and we …watched 'Get Smart' on her big blank wall in her house and she projected it on this little machine that you put the DVD in and it comes out the lense.
A bright light lights the slide (a prepared positive cut from the original film). The light travels through a lens to focus it and on to a screen. There are many mechanisms to… change slides, from manual insertion, to rotary and linear slide trays.
Yes, the new ones such as samsung galaxy note or s3 with adapter will work with HD TV and also projectors with hdmi in.
A powerful beam of light through the transparent slide image is focused by a convex lens to produce an image on a screen .
It is impossible unless you hook it up to another computer or laptop
A micro projector works by taking an image, scanning it, and then resizing it to the desired size. This is actually really how all of the projectors work.
The projector phone is just what the name describes! It is both a smart phone and a portable projector. It gives the convenience of portability and professionalism in your poc…ket. It works just like a regular projector showing files from your phone and/or slides. It also has convenience of bluetooth, so that you can use your phone hands free. It utilizes a touch screen feature, making it easy to navigate.
The principle of LCD projector is to display different thing larger like video ,images, computed images and different items large .
Do you mean connect it to a projector? If so, you need a projector, your computer and a special screen cord. Connect the cord to your computer and projector and is should work…!
