Stop video recording from Camera Board
You can create a connection to the Camera Board, take a photograph, and record video.
Create a connection to the Raspberry Pi™ board.
mypi = raspi;
Create a connection to the Camera Board while changing the resolution, and assign that connection to a handle, mycam. The handle 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 ten snapshots on your host computer.
for ii = 1:10 img = snapshot(mycam); imagesc(img); drawnow; end
If the image is upside down, change the orientation of the image.
mycam.Rotation = 180;
You can use the same approach to change the values of many mycamera properties listed in the "Name-Value Pair Arguments" for cameraboard.
Record a 60 second video.
Stop recording before the 60 seconds have elapsed.
Copy the video from the board to your host computer.
Delete the video file from the board to free up space.
