Image brightness from a projector is normally measured in ANSI lumens. Lumens is a brightness measurement and ANSI lumens is a method of standard brightness measurements for projected images. The measurement is based on certain video levels and patterns and helps to compare the outputs from different projectors.
Most manufacturers now quote an ANSI lumen figure although some choose to quote a lumen level that may not be based on the ANSI measurement system. The non ANSI levels will generally be a rather higher figure so they do not offer a comparison with industry standard measurements.
Apparent brightness is also dependent on the ambient light falling on the screen as well as the contrast range of the image itself. For these reasons, don't let the brightness rating influence a choice of model without taking other factors into account.
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 variety 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.
Lumen is a simple way to indicate the amount of light the projector has to produce the brightness of the picture. The higher the number the brighter the picture.
Yes, a projector is a peripheral.
A projector that projects images from 35mm slides.
what are the advantages of a data projector
Brightness is measured in ANSI lumens. For home theater projectors, brightness typically ranges from 700 - 2000 lumens or more. Your viewing environment will be a big part of determining how bright your projector needs to be. Dedicated home theaters (rooms with controlled lighting and no ambient light) will not require as much brightness as a space with ambient light from windows or other household lighting.
An apparent brightness is the brightness of a star as measured by an observer.

Noot always, this depends more on the brightness rating of the projector, instead of the display technology.
The power consumption of an basic model of LCD projector is around 250W to 400W depending on the make and model, brightness 2000 to 3000 ansi lumens SVGA projector.

Both are unit of brightnes and usually shows numerical value of brightness in projector. lumen is measering unit of each pixel which generates by light source .it tallest brightness away from centre and other mansion is equally distributed cause of generated by led .
The measure of a star's brightness is its magnitude. A star's brightness as it appears from Earth is called its Apparent Magnitude.Star's brightness is measured by there magnitude.

Brightness of light sources is measured using a unit called lumens. Lumens indicate the total amount of visible light emitted by a source, with higher lumens corresponding to greater brightness.
The relationship between brightness and perception in lighting, measured in lumens, demonstrates a logarithmic scale because our perception of brightness increases more slowly as the actual brightness increases. This means that doubling the lumens doesn't result in a perceived doubling of brightness.
