Hello
I have a problem about the video input program which introduced at the link below.
https://www.mathworks.com/help/imaq/examples/laser-tracking.html
When I executed this example program, the error occurred.
The error is
error: videoinput (line 324)
The FORMAT specified is not supported by this device. See IMAQHWINFO(ADAPTORNAME).
error: demoimaq_LaserTracking (line 51)
vid = videoinput('winvideo', 1, 'RGB24_320x240');
How can I solve it?
I tried below;
・checked "Image Processing Toolbox™" & "Image Acquisition Toolbox™" installation
・installed some hardware support packages "Image Acquisition Toolbox Support Package for OS Generic Video Interface" & "MATLAB Support Package for USB Webcams"

Your camera does not support 320×240 in 24 bit rgb.
What is the output of
imaqhwinfo('winvideo')
