Crop controls

Zoom

It is possible to zoom between the sensor size selected and the output size (if the output

size selected equals the sensor mode size then no zoom can take place).

The zoom step size in both the horizontal and vertical directions are selectable and zoom

controlled with the commands zoom_in, zoom_out and zoom_stop.

Pan

It is possible to pan left, right, up and down when the output size selected is smaller than the

sensor size selected. (if the output size selected equals the sensor mode size then no pan

can take place).

The pan step size in both the horizontal and vertical directions are selectable.

Frame rate control

The VS6624 features an extremely flexible frame rate controller. Using registers

uwDesiredFrameRate_Num, and uwDesiredFrameRate_Den any desired frame rate

between 2 and 15 fps can be selected for the SXGA sensor mode and between 1 and 30fps

for a VGA sensor mode. To program a required frame rate of 7.5 fps the numerator can be

set to 15 and the denominator to 2.
