Display Mode
There are three display modes: Full Screen, Split Screen, and Bypass. Pressing the Display Mode
switch cycles thru these modes and updates the indicators to show the currently selected mode.
In Full Screen mode, the entire video field is enhanced per the current parameters.
In Split Screen mode, the left half of the video field is left unenhanced (see BYPASS below) while the
right half of the video field is enhanced per the current parameters. This allows a convenient method
for comparing the effects of enhancement in a side-by-side manner.
In Bypass mode, the enhancement parameters are all set to unity gain such that the data output from
the EVD1000 exactly matches the data input to it. Note that in this mode, the enhancement level
indicators are OFF; also, note that the data still passes through the input and output conversion
stages.
Preset Enhancement Levels
There are three preset enhancement levels that are selectable on the Demonstrator board: low,
medium, and high. Note that these names do not necessarily indicate relative levels, since it is
possible to store virtually any combination of enhancement parameters in each of the three preset
positions, see below; however, the factory default settings do correspond to general “low,” “medium,”
and “high” levels of enhancement. Pressing the Enhancement Level switch cycles thru these presets
and updates the indicators to show the currently selected level (unless, as indicated above, the
current Display Mode is set to BYPASS).
Advanced Feature Interface
For further investigation of the EVD1000 series capabilities, including the numerous enhancement
parameters which control the detailed characteristics of the processing performed, the registers in the
EVD1000 on the Demonstrator board can be accessed directly via an external PC connected to the
board by means of a standard USB cable. EVD provides VideoTuner, a Windows®-based (Windows
2000, XP, and Vista) application for this purpose. The latest version can be downloaded from EVD
on the web. Installation is generally straightforward and performed in the usual manner. Detailed
installation instructions for this application can also be found in a separate Application Note.
The EVD application contains the ability to control each of the registers in the EVD1000 series chips
using on-screen sliders. A panel is provided which, by default, contains sliders for several of the
parameters which we have found most often adjusted in customizing the chip’s performance to
specific applications and in tailoring the enhancement to suit a particular customer’s image
processing preferences. The user can create custom sets of such sliders, as well as initial values for
those parameters, and save and restore these using the local PC hard drive. An Application Note
describing the use of this application in accessing these and other advanced operational features is
available, as well as the EVD1000/1500 data sheet which discusses the available parameters.
Advanced users can also write their own software to control the setting of EVD1000 series
parameters on the Demonstrator board; commanding protocol information is available from the
factory. This can be done, for example, as a precursor to the user-developed software running in a
microprocessor on a customer’s board designed for a specific application.
