3.3 Video Data Output Modes

The A202k 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 A202k 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.
