3.3 Video Data Output Modes
The
A202
k
can output video data using two different modes: dual 10 bit mode, or dual 8 bit mode.
In dual 10 bit mode, the camera outputs data for two pixels on each cycle of the pixel clock and
the pixel data is at 10 bit depth. In dual 8 bit mode, the camera outputs data for two pixels on each
cycle of the pixel clock and the pixel data is at 8 bit depth. These modes are described in detail in
Section
2.5.4.2 .
You can select the video data output mode using either the Camera Configuration Tool Plus (see
Section
4.1 and the configuration tool’s on-line help) or binary commands (see Section 4.2 ). With
the configuration tool, you use the Video Data Output Mode setting in the Output group to select
the data output mode and with binary commands, you use the Video Data Output Mode binary
command.
3.4 Integrate Enabled Signal
An output signal called Integrate Enabled (IntEn) is available on
A202
k
cameras. The integrate
enabled signal indicates that an exposure is taking place. The signal will go high when each
exposure begins and go low when the exposure ends. The characteristics of the signal are
described in more detail in Section
2.5.5 .
This signal is especially useful when you are operating a system where either the camera or the
object being imaged is movable. For example, assume that the camera is mounted on an arm
mechanism and that the mechanism can be used to move the camera to view different portions
of a product assembly. Typically, you do not want the camera to move during exposure. In this
case, you can monitor the IntEn signal to know when exposure is taking place and thus know
when to avoid moving the camera.
In cases where flash exposure is required, the integrate enabled signal is useful as a flash trigger.
