Acquisition Parameters Tab

Change video acquisition parameters from the Acquisition Parameters tab.

• Video Mode displays a list of all available video modes for the camera. Select the appropriate video mode. If you select Format 7, you also must set the Color Coding mode.
• Color Coding displays a list of available color coding modes for the camera in Partial Image Format (Format 7) mode. For non-Format 7 modes, this parameter returns the default color coding for the camera. Refer to the camera documentation for the appropriate color coding.
• Speed displays a list of available transfer speeds for the camera. The default is 400 Mbps.
• Region of Interest controls the acquisition window of the camera. The four parameters are Left, Top, Width, and Height. For Format 7 mode, these parameters affect the amount of data sent across the IEEE 1394 bus. For non-Format 7 modes, these parameters affect the amount of data decoded by the driver.
• Timeout sets the number of milliseconds the driver waits for the acquisition to complete before returning a timeout error. The default is 5,000 ms.
• Packet Size specifies the number of bytes transferred in each data packet. Changes to this parameter affect the number of packets required to transmit an image over the IEEE 1394 bus. Larger values transfer images faster. Smaller values allow more cameras to coexist on the same bus.
• Ignore First Frame pauses for a frame interval before returning an image. Set this option if a snap acquisition returns an incorrectly exposed image.
• Actual Bit Depth specifies the number of bits per pixel that contain image information. This parameter applies only to images with 16-bit components.
• Bit Alignment specifies the alignment of pixel information in memory. Refer to the camera specifications for the correct alignment. The default is Least Significant Bit (LSB). This parameter applies only to images with 16-bit components.
• Byte Order specifies the order in which multibyte data is stored. Refer to your camera specifications for the correct byte order. The default is Big Endian. This parameter applies only to images with 16-bit components.
