Auto-Image

Auto-Image

Use either Adjust knob ([ {) to turn Auto-Image on or off (default).

When enabled and a new input frequency is detected, the DVS first applies an existing Auto Memory for the signal (if Auto Memory is enabled), or, if no entry exists, performs an automatic Auto-Image on the new signal. This automatically attempts to size/position the image to fill the screen, with respect to the current aspect ratio setting.

With Auto-Image disabled, the DVS 605 will apply default values to a new input if no Auto Memory exists (if Auto Memory is enabled).

Auto-Image threshold settings

By default, the Auto-Image function considers any analog video with a >25% brightness to be active video. Some video sources, such as dark PC backgrounds, or dark borders around a presentation, may require a lower “Auto-Image threshold,” to ensure incoming video is properly sized and centered by the Auto-Image function. Other scenarios, such as upstream analog twisted pair extension products, may require a greater Auto-Image Threshold setting in order to allow the DVS 605 to ignore extraneous sync pulses that may have been embedded in the RGB signals.

A global analog video Auto-Image threshold value can be set via an SIS command or using internal web pages.

The range is 0% (black / ~0.0 VDC) to 100% (white / ~0.7 VDC), with a default value of 25%.

NOTE: The Auto-Image threshold setting only affects analog input signals, and has no

effect on digital inputs, which are sized and centered automatically.

Auto Memory

Use either Adjust knob ([ {) to turn Auto Memory on (default) or off.

The DVS 605 stores 32 auto memories per input, with input configuration and picture control data for each input. The default settings enable these memories to automatically recall input and picture controls for signals that have been previously applied. When auto memories are disabled, the DVS treats every newly applied input as a new source. Default for Auto Memory is on.

On

On

“New” signals/rates that have not been previously detected by the DVS are initially

 

 

set up using default parameters, then Auto-Image is automatically applied and values

 

 

stored. The next time that signal is detected, the values stored in the auto memory

 

 

location are applied.

“New” signals/rates that have not been previously detected by the DVS are set up using

(Default)

default parameters. If manual input and/or picture settings are made to the input, an

 

 

auto memory location is created and recalled each successive time the input is detected.

 

 

 

Off

On

Each change in input sync, input switch, or power cycle triggers an automatic Auto-

 

 

Image. When auto memory is disabled, each change in sync is treated as a new signal

 

 

and an automatic Auto-Image is triggered. Any manual changes made to the image and

 

 

picture controls are lost each time a new rate is detected.

 

 

 

Off

Off

Each change in input sync causes default values to be applied to the rate. Any manual

 

 

changes made to the image and picture controls are lost when a new rate is applied.
