The position of the target will be used to determine the

calibration value that shifts the row and column position of

adjustable overlay graphics.

The overlay calibration is intended to be applied on a

device by device basis “in system,” which means after the

camera has been installed. ON Semiconductor provides

basic programming scripts that may reside in the SPI Flash

memory to assist in this effort.

OVERLAY CHARACTER GENERATOR

In addition to the four overlay layers, a fifth layer exists

for a character generator overlay string.

There are a total of:

• 16 alphanumeric characters available

• 22 characters maximum per line

• 16 x 32 pixels with 1-bit color depth

Any update to the character generator string requires the

string to be passed in its entirety with the Host Command.

Character strings have their own control properties aside

from the Overlay bitmap properties.
