4. COMMENTARY
4.1 External appearance design
This product follows the same design concept and coloring as the earlier models, LV-
7325/LV-7320 to establish a unified image for Canon Multimedia Projectors. Some of
the major design points, which are basically the same as the other Canon Multimedia
Projectors, are outlined below.
●
External Styling
The body is designed with subtle curves and the coloring and semi-transparent body
panels follow the lead of the LV-7300 series. Indications of the excellent lens
performance are printed around the lens to convey an impression of high picture
quality.
●
Operating Keys
The operation and cursor key layout is a simple, intuitive layout with grouping to
insure ease of use.
●
Coloring
The body of the projector is colored glacial blue. The front of the unit, with an
appearance fittimg a product from an optical equipment manufacturer, has an
aluminum lens ring and is colored arctic silver. The overall effect is to emphasize the
lens and evoke a sophisticated image.
The operating keys are a special "mercury silver" color that is easy to see in dim light
and also serves as a design accent point.
4.2 Hybrid gamma correction
Hybrid gamma correction is a new feature. It combines digital gamma correction and
analog gamma correction, and takes advantage of the characteristics* of both. Using the
on-screen menu, the user can take advantage of this new feature to control image
gradation.
* Analog gamma correction: analogue correction is applied to the non-linear analog
circuit. In analog correction transitions between gradations
are smooth.
* Digital gamma correction: Correction is applied through digital processing of the X/Y
gamma curve. Using a digital signal, varying the
characteristics curve, for example, is simple. Because
digital processing is involved, however, transitions between
gradations can be abrupt.
