• CFA (Color Filter Array) to RGB (Red, Green, Blue) conversion
• Display controller
• Picture In Picture (PIP)
• 4K image panning through 1920×1080 output via HDMI 1.4 TX port
• Edge detection
• Image enhancements such as contrast, brightness, or color balance
• Send GenICam commands from the CXP Host to CXP Device to control camera settings.
• Fetch XML file from the CXP Device to CXP Host to save it on the host computer and displaying on the user interface (GUI).

Note: The solution includes a user-friendly GUI to control these image/video settings and support for GenlCam commands.

• The Full HD HDMI monitor displays the camera feed from the 2 cameras as Picture in Picture.

Running the Demo
The demo features receiving the MIPI Rx data from the two cameras with 4K resolution at 30 frames per second (fps). The 4K MIPI video data from the 2 cameras is converted to CoaXPress data using the CoaXPress IP and transmitted over the coaxial cable. The CoaXPress data received from the host board is converted in to video data using the CoaXPress IP. The received video frames from CoaXPress are stored in DDR and passed on to the display as per the display controller timing parameters. The image processing IPs are enabled on the display side of the video pipeline.
In the demo design, display controller is used to provide the Full HD output (1920×1080 60 Hz resolution). The Full HD output supports PIP, panning, Edge Detection, and Image enhancements such as contrast, brightness, color balance, and alpha blending.
Running the demo involves adjusting the imaging and video settings using the CoaXPress – GenICam GUI and then observing the result on the HDMI monitor.
To use the demo GUI:

1. Start the CoaXPress – GenICam GUI from the Program menu.
   The GUI is displayed as shown in the following figure.
   Figure 8 • CoaXPress – GenICam GUI

2. Select the second largest COM port on the GUI and select the Connect option.
   Figure 9 • Connecting the GUI and Video Kit

3. The Connect button turns green indicating a successful connection.
   Figure 10 • Connection Successful

4. Use the Contrast and Brightness sliders to adjust the contrast and brightness and observe the change on the HDMI monitor. The sliders are highlighted in the following figure.
   Figure 11 • Adjusting Contrast and Brightness

5. Similarly, adjust the color balance of the image using the color balance sliders.

6. Adjust the Alpha slider. The alpha blending feature enables adjusting the transparency of the PIP image. When the alpha value is adjusted to minimum (0), the image disappears.
   Note: Default image settings can be reverted by using the Reset option.

7. Switch to Edge Detection mode using the Edge option.

8. Select the PIP Menu to change the PIP settings.

9. Select the source of the PIP window between Camera 1 and Camera 2 using PIP: Source Select. The position of the PIP window can be moved anywhere within the screen by dragging the pink PIP box. The Auto Mode Start option moves the PIP window automatically. The speed of this movement can be controlled using the Auto Mode Step slider.
   Figure 12 • PIP Menu

10. Close the PIP Menu.

11. In the main video control GUI window, select the Panning option to view a particular area of the main or the PIP image within a 4K image.

12. In the Panning Menu, use Image Select to select the image to be panned (Main image or PIP image). Any area of the 4K camera feed can be viewed by dragging the pink box horizontally or vertically. The Reset option sets the view of the Main image and PIP image to its default center position.

13. Close the Panning Menu to return to the main GUI.

GenICam GUI Features
This allows various GenICam commands to be sent from the Host to Device. The selection is made from the Command drop down.

1. Select the command to be sent to the device.
   The address menu will be active for Read_Bootstrap and Write_Bootstrap command.

2. Select the address to be accessed with the Read_Bootstrap or Write_Bootstrap command.
   Figure 14 • Selecting GenICam Command
   Figure 15 • GenICam Address Menu

3. Click Send Command to read bootstrap register from the device.
   Read_Bootstrap command illustration is as shown below for Address Standard. The output for the selected command is: C0 A7 9A E5.
   Figure 16 • Read Command Output

4. For write command, enter the value in the Data (hex) section that needs to be written to the register.
   Successful completion of write command displays 01 01 01 01 in the Hex Log window.
   Figure 17 • Write Command Output

5. Fetch_XML_File command reads the XML file from device memory and displays the file in the log window.
   This command performs read on XmlUrlAddress bootstrap register that provide details
   (Local:xml_mchp_desc.xml;8100;08a8?SchemaVersion=1.0.0) of the file starting address (8100) and the file size (08a8) of this file in the Device Memory. This is displayed first in the log window. It will issue commands to read XML file till the entire file is read.

6. Use Save XML to save the last received xml file in the log on to a xml file in the Host PC.
   Figure 18 • Fetch XML Command

7. Fetch_Magic_Number command performs read operation on Bootstrap address 0x0 and displays the data.

8. Display_XML_FILE command displays XML file stored in the host memory. For this command to work, Fetch_XML_File command should have been issued before.

9. Camera module on device supports flipping the video capture horizontally. The same can be performed by sending the HORIZONTAL_FLIP_EN command. Enter value 0x1 to flip and write value 0x0 to revert it back to the normal video. Observe the video on screen.

10. Camera module on device supports sending the pattern instead of video from camera. The same can be performed by sending PATTERN_EN command with value in the data as 0x1. Run the same command with the data as 0x0 and it reverts back to the camera video. Observe the changes on screen.
    Note: Command outputs can be viewed in Hex or ASCII formats in the respective tab. The XML file is best viewed in the ASCII format tab. Most of the other commands are best viewed in the Hex format tab. There are buttons to Clear Log and Save Log.

11. The user has the option to access the address, which are not available in the Address drop down menu by using the … option.
    Figure 19 • GenICam Address Other

12. Close the GUI to exit from the demo.
    This concludes the demo.
