I have software which I wrote, that takes the data
from the camera, and memcopy's it into a JNI byte array, which then passes it to
Java for drawing. It is a black and white feed, and works great, running
at 33fps, 160x144. On occasion, when our system starts, there is a black
line on the left side of the image, 1 pixel wide, and a gray solid line next to
that, also 1 pixel wide. The rest of the image is fine. If it was
constant, I would guess it was my code...but it is very inconsistent. I
have 3 machines that I'm testing this on, and it happens quite frequently on one
system, occasionally on another system, and the third it almost never
occurs...which suggests hardware to me. In my previous version, the
drawing was done in C++ by grabbing the Canvas from Java and
drawing it to the drawing surface in C++. I don't remember ever
seeing this issue with that version...which suggests a software
issue. They all are running the same version of v4l, and ov511.
I believe my v4l version is 4.2.0, and my ov511 version is 1.57. Any ideas
what could cause this random black line?
