Stamp
The stamp feature provides the user with information about the area of interest settings of each
captured image. When the stamp feature is enabled, the video data of the last 11 pixels of the last
image line, that is, the bottom right of each transmitted image is replaced by 11 stamp pixels. Each
stamp pixel carries an 8 bit value that conveys information about the area of interest of the
transmitted image.
The table below shows the function of each stamp pixel by position. A more detailed explanation
of how to interpret the pixel values follows the table.
Stamp Pixels S1 and S2:
Stamp pixels S1 and S2 are only active when the Programmable AOI
Sequencer feature is used (see Section
). S1 represents the position number of the area of
interest within the AOI sequence. You can look up the position number in the AOI list so you know
which settings were used to capture the image. S2 represents the run counter. If the
Programmable Area of Interest Sequencer feature is disabled, all bits are set to 0.
Stamp Pixel S3:
Stamp pixel S3 represents the 8 bit frame counter. The frame counter increments
by one for each image captured by the camera. The counter starts at 0 and wraps at 255
(decimal). The frame counter is reset to 0 whenever the camera is switched off or reset. It is also
reset to 0 when the stamp feature is disabled.
Stamp Pixels S4 through S11
: Stamp pixels S4 and S5, S6 and S7, S8 and S9, and S10 and
S11 represent the most significant byte and least significant byte (respectively) of the AOI starting
column, AOI width, AOI starting line, and AOI height.

Table 3-2: Stamp Pixel Functions

When the camera is operating in an 8 bit output mode, the stamp pixels will be 8
bit values. When the camera is operating in a 10 bit output mode, the stamp pixels
will be 10 bit values but only the 8 LSBs will carry information. The two MSBs will
be packed with zeros.
