1. FEATURES
1.1 Development objectives
With its sights firmly fixed on the SOHO-HOME market, Canon introduced the LV-
5100 B5 file size microportable* multimedia projector to consumers last year.
Equipped with a 0.7-inch liquid crystal panel, this LCD projector has been offering a
more compact size and greater portability at an even lower cost than before. In contrast,
Canon's competitors in this product range have brought out projectors with the same
high brightness to be found in liquid crystal projectors featuring 1.3-inch and 0.9-inch
liquid crystal panels.
Now following on the heels of the LV-5100 as its successor is the LV-5110 multimedia
projector. It employs a high-brightness lamp, and its aim is to maintain the company's
competitive edge in this product field while further opening up the market.
*Microportable: Defined by Canon to mean an LCD projector that weighs less than 3kg.

1.2 Major Features
●Compact, lightweight 2.7kg/B5 file size micro-portable type
Real SVGA compatible, class-leading 850 ANSI lumen output
●Supports HDTV&DVD component input
Beautiful image reproduction with minimal burring of color
●Equiped with Digital Keystone function
Smoothly corrects for "keystone" effect caused by projector tilt, giving a square image
with up to 15 degrees tilt.
●Plug and Play: Simply plug in computer or AV components and start - no adjustments
required.
1) Multiscan System automatically detects PC vertical and horizontal scan
frequencies
2) Video color system: Automatically detects system (NTSC/PAL; SECAM/NTSC4.43)
PAL-M/PAL-N can be selected from menu bar)
3) Tracking: Auto Imaging function automatically tracks and optimally positions
image
4) Graphic User Interface (GUI): The graphic user interface simplifies image
adjustments in varying environments.
5) Six Language support: English, French, German, Italian, Spanish and Japanese
are supported
6) Wireless Remote Control: Remote control has mouse control functions
●Temperature-sensing Real Time Fan Control: Unobtrusive sound level for conferences
●Gamma Correction: Gives high quality reproduction of gradation
Part 1: General Information

1.3 LV-5110 Features (Details)
●Brightest in the SVGA Micro Projector class - 850 ANSI Lumens
1) Large screen presentation even in brightly lit conference rooms
2) 132W UHP short arc lamp for bright images with great color balance
●Real projection SVG (800 x 600 dot) Digital compression XGA/SXGA high-definition
projection *
0.7" LCD Panels used (for the first time)
●Supports input from HDTV&DVD components
Color defference signal (Y, Pb/Cb, Pr/Cr) input reproduces the images with minimal
burring of color.
* Composite (Video) input is common to the Brightness (Y) input.
●Digital Keystone distortion compensation
When the projected image surface and the projector are offset, the image has a
trapezoidal shape, but this can be smoothly compensated with offsets up to 15
degrees.
A simple operation gives a square image without adjusting the height of the projector.
●Gamma Correction
To avoid washed-out whites and murky blacks the user can control the middle
brightness.
●Plug and Play: Simply plug in computer or AV equipments and start - no adjustments
required.
●Power Management: improves lamp life
After a predetermined time (5' 30") with no input signal, the lamp is turned off. When
a signal is input, it turns back on.
●Simple wireless remote control
1) Supports all remote functions
2) P-Timer button supplies presentation elapsed time
3) Functions as the mouse control for connected PC
●Manual zoom and focus controls included
●Digital zoom enlarges any selected part of the presentation image
●Cues up the next screen without pausing or projecting an unnecessary operation
screen. (Freeze function)
●The image can be turned off without turning the power off and immediately turned back
on - Image shut-off function.
●Noise is cut in the absence of a signal - Blue Back function.
Part 1: General Information

●Impressive image size - up to 200 inches.
●Reverse image function allows the unit to be suspended from the ceiling or used as a
rear-screen projector.
●Reduced lamp problems (Replace Lamp Indication)
1) The replace lamp indicator shows when it is time for a change.
2) Lamp replacement by the user is simple.
●The design emphasizes the lens, as you would expect from a Canon product.
* With digital compression projection, some information is lost.
