Phantom Miro Control via "Touch-Sensitive" LCD Screens 291

· Area - the percentage of the auto-trigger region that must be active in order for an auto-

trigger event to be generated. A typical percentage value is 10.

· Threshold - the amount a pixel value must change in order to be counted as an active

pixel for auto-trigger purposes. A value of 100 would require a change of approximately

half of the full swing of the camera. A typical threshold setting would be 10.

A larger sensitivity setting means a lower area and threshold.

Update

The Update, (Speed), Selector defines the number of frames between updates of the auto-

trigger reference memory. A value larger than 1 allows the trigger to activate on slower

events.

Image changes are evaluated over a time interval of auto-trigger speed/frame rate.

A larger update number will make the trigger slower as it will compare an image over more

frames.

Enable

Ensure the Image-Based Auto-Trigger is set to enable.

RESULT: Camera is set to use Image-Base Auto-Trigger feature.

Image-Based Auto-Trigger Region Tables

NOTES

X and Y defines the center of the auto-trigger region, relative to the center of the image size.

H specifies the height of the auto-trigger region. If zero the height will be either 1/4 of the image

height, or 16 pixels, whichever is larger.

W specifies the width of the auto-trigger region. If zero the width will be either 1/4 of the image

width, or 128 pixels, whichever is larger.
