New multi-media projector from Canon Designed for educational use
Canon, leader in photographic and imaging technology, today announces the LV-X4 – a new multi-media projector designed especially to suit the requirements of the education market. The 1500 ANSI lumens projector produces an image that is both bright and clear, and complies with the requirements outlined by Becta (British Educational Communications and Technology Agency) for classroom use*. Canon brings its optical heritage and technical expertise into the classroom with the LV-X4, which features high resolution native XGA projection for crisp images and a high contrast ratio of 400:1 for vivid colours, with an affordable price tag for education budgets.
The 1.6x zoom lens allows flexibility when positioning the projector and the wide angle of the lens provides a large image when the projector is close to the screen. The LV-X4 also incorporates a range of features to automatically maximize image quality and increase flexibility of use. These include an ‘Auto Image mode’ for automatic brightness adjustment and eight flexible image settings – including a Blackboard mode designed especially for classroom use – for optimal results in different lighting conditions. Progressive scan replication with interlaced video signals provides smoother movement and sharper text. Vertical keystone adjustment corrects image distortion when the projector is angled up or down.
Flexible image settings for better images
The eight image settings ensure picture quality is always optimized – both data projection and video projection modes can be selected with four sub-modes. Data projection can be set to standard, Hi-Contrast (for sharper graphs and photographs), custom and Blackboard modes. Video projection can be set to standard, cinema (designed for watching movies in darkened rooms), custom and Blackboard modes. Blackboard mode is designed to supply the ideal colour balance when projecting onto the dark surface of classroom blackboards. Custom modes for both data and video allow a range of settings (including gamma, or brightness) to be manually adjusted to tailor the image to a specific environment.
Auto Image mode handles variable light conditions
For low light or darkened room conditions, areas in the projected image that are supposed to be jet-black can sometimes be tainted with light grey if the projector lamp is too bright. The LV-X4’s Auto Image mode automatically compensates for this effect by continuously measuring ambient light and adjusting lamp output accordingly. This results in perfectly balanced brightness – even in constantly changing conditions – without the need for manual adjustments.
Progressive scanning for smooth video projection
Image flickering often visible in conventional projectors is generally caused by a method of projection known as interlaced scanning, which merges two fields to produce a single frame. The LV-X4 uses progressive scanning, which draws the entire frame continuously from top to bottom, greatly reducing flicker and producing cleaner diagonal lines, titles and sub-titles.
Flexible placement
The LV-X4 is portable, compact and lightweight (weighing 2.8 kg and featuring an A4+ footprint), offering great flexibility of location. The LV-X4’s 1.6x manual zoom provides the right image size at a wide range of throw distances. The wide angle of the lens ensures large image projection even when the projector is very close to the screen, producing a 100-inch diagonal screen from a 100-inch (2.5m) distance. The vertical keystone adjustment corrects trapezoidal distortion when the projector is angled up or down - perfect for ceiling installation.
Quiet and comfortable
A quiet mode reduces fan noise from 39 dB to just 35 dB for exceptionally quiet operation in hushed settings. The new Linear Fan Control feature also helps create a comfortable viewing environment by automatically adjusting the fan system – fan voltage is calibrated with respect to room temperature, so fan noise is never in excess.
Advanced multimedia connectivity
With its Analogue In/Out connection, the LV-X4 offers high-quality projection from a wide array of audio-visual devices, including VCRs, DVD players, digital camcorders and game consoles. The projector can also be connected to an external monitor. Optional SCART connectors and Component Video adapters are available.
Customization and control
The LV-X4 can be customized to project the user’s logo as soon as the projector is turned on – useful for both security purposes and for maintaining a professional impression. A Key Lock function can disable the keys on either the remote control or the projector’s control panel, giving just one person control of the presentation. The remote control incorporates useful new features including mouse right click functions and spotlight function.
Pricing, availability and reader enquiries
The LV-X4 will be available from 1 September 2004 for around £1320 inc. VAT.

* Becta, the British Educational Communications and Technology Agency, recommend a maximum ANSI lumens of 1500 on projectors for classroom use except for video projection where it is unlikely that a person will be standing in the beam.
