Dear Laurent-san
Thank you for your advice.
Now I can set the size parameter.
An additional question, please.
I can now display the image up to 3280x1908 size and save the jpeg file,
but I cannot see 3280x2464 full-size image.
Please see attached message log when error occurs.
PS
The aspect ratio of the display is sometimes incorrect. The aspect of Jpeg file is OK.
I appreciate your kind advice in advance.
Best Regards,
NOMURA

The syntax is
qcam -s width=1280,height=720
without any space after the ','. I've just tested it with a UVC camera as my Raspberry Pi isn't plugged in right now, but it should work there too. If it doesn't, we can look into it.
