Hi, the HD1 when connected to RPi 3B+ can capture video with raspivid well, but when raspistill is run, the picture does not capture full screen of the input source.
My source is 1920×1080 1080p, and I used command
raspistill -md 1 -o file2.jpeg -q 100
to capture a still. The resulting picture has resolution of 2592 x 1944, instead of 1920 x 1080. As you can see that the ratio of w:h is off, the left and right parts of the input source are not captured in the still.
Any idea why it might happen or advice for what to try?
It seems that you need to use the -w and -h parameters with raspistill to control the output resolution – the size you are seeing matches the full frame resolution of the RPi camera.
There are some forum posts that discuss the issue here: https://www.raspberrypi.org/forums/viewtopic.php?t=128764
