Stop video recording from Camera Board
You can connect to the camera board from the MATLAB® software, take a photograph, and record video.
Create a connection from the MATLAB software to the Raspberry Pi™ hardware.
mypi = raspi
Create a connection,
mycam, from the MATLAB software to the camera board, and set the image resolution. The connection
displays the camera board properties.
mycam = cameraboard(mypi,'Resolution','1280x720')
mycam = Cameraboard with Properties: Name: Camera Board Resolution: '1280x720' (View available resolutions) Quality: 10 (1 to 100) Rotation: 0 (0, 90, 180 or 270) HorizontalFlip: 0 VerticalFlip: 0 FrameRate: 30 (2 to 30) Recording: 0 Picture Settings Brightness: 50 (0 to 100) Contrast: 0 (-100 to 100) Saturation: 0 (-100 to 100) Sharpness: 0 (-100 to 100) Exposure and AWB ExposureMode: 'auto' (View available exposure modes) ExposureCompensation: 0 (-10 to 10) AWBMode: 'auto' (View available AWB modes) MeteringMode: 'average' (View available metering modes) Effects ImageEffect: 'none' (View available image effects) VideoStabilization: 'off' ROI: [0.00 0.00 1.00 1.00] (0.0 to 1.0 [top, left, width, height])
Import and display a sequence of 10 snapshots on your computer.
for ii = 1:10 img = snapshot(mycam) imagesc(img) drawnow end
If the image is upside down, change its orientation.
mycam.Rotation = 180

Record a 60 second video.
Stop the recording immediately.
Copy the video from the board to your computer.
Delete the video file from the hardware to free up space.
You can deploy
