Yes I’m indoor lighted with neon lights
For each test my procedure is :
- use the command line,
- check the picture,
- use a lamp to saturate a part of the camera, wait for 10 seconds and see if the image global luminosity change
Here are my tests where I try all values of wbmode :
gst-launch-1.0 nvcamerasrc fpsRange="15 15" auto-exposure=1 exposure-time=.03 wbmode=0 ! nvoverlaysink
The picture is a little dark and colours are ok
With light, the global luminosity doesn’t change
gst-launch-1.0 nvcamerasrc fpsRange="15 15" auto-exposure=1 exposure-time=.03 wbmode=1 ! nvoverlaysink
Exactly the same results
gst-launch-1.0 nvcamerasrc fpsRange="15 15" auto-exposure=1 exposure-time=.03 wbmode=2 ! nvoverlaysink
The picture is a little dark and the image looks more blue
With light, the global luminosity doesn’t change
gst-launch-1.0 nvcamerasrc fpsRange="15 15" auto-exposure=1 exposure-time=.03 wbmode=3 ! nvoverlaysink
The picture is a little dark and the colours are ok
With light, the global luminosity doesn’t change
gst-launch-1.0 nvcamerasrc fpsRange="15 15" auto-exposure=1 exposure-time=.03 wbmode=4 ! nvoverlaysink
The picture is a little dark and the image looks more blue
With light, the global luminosity doesn’t change
gst-launch-1.0 nvcamerasrc fpsRange="15 15" auto-exposure=1 exposure-time=.03 wbmode=5 ! nvoverlaysink
The picture is a little dark and the image looks more yellow
With light, the global luminosity doesn’t change
gst-launch-1.0 nvcamerasrc fpsRange="15 15" auto-exposure=1 exposure-time=.03 wbmode=6 ! nvoverlaysink
The picture is a little dark and the image looks more yellow than daylight
With light, the global luminosity doesn’t change
gst-launch-1.0 nvcamerasrc fpsRange="15 15" auto-exposure=1 exposure-time=.03 wbmode=7 ! nvoverlaysink
The picture is a little dark and the image looks more yellow than daylight
With light, the global luminosity doesn’t change
gst-launch-1.0 nvcamerasrc fpsRange="15 15" auto-exposure=1 exposure-time=.03 wbmode=8 ! nvoverlaysink
The picture is a little dark and the image looks more yellow than daylight
With light, the global luminosity doesn’t change
- (9): manual and wbManualMode = 0 (off)
gst-launch-1.0 nvcamerasrc fpsRange="15 15" auto-exposure=1 exposure-time=.03 wbmode=9 wbManualMode=0 ! nvoverlaysink
The picture is a little dark and the colors are ok
With light, the global luminosity doesn’t change
- (9): manual and wbManualMode = 1 (reset)
gst-launch-1.0 nvcamerasrc fpsRange="15 15" auto-exposure=1 exposure-time=.03 wbmode=9 wbManualMode=1 ! nvoverlaysink
The picture is a little dark and the colors are ok
With light, the global luminosity doesn’t change
- (9): manual and wbManualMode = 2 (restore)
gst-launch-1.0 nvcamerasrc fpsRange="15 15" auto-exposure=1 exposure-time=.03 wbmode=9 wbManualMode=2 ! nvoverlaysink
The picture is a little dark and the colors are ok
With light, the global luminosity doesn’t change
- (9): manual and wbManualMode = 3 (external-gains)
gst-launch-1.0 nvcamerasrc fpsRange="15 15" auto-exposure=1 exposure-time=.03 wbmode=9 wbManualMode=3 ! nvoverlaysink
The picture is a little dark and the image get only green component no red or blue, but I have the picture.
With light, the global luminosity doesn’t change
On this test I don’t know how to change luminosity in command line. In my preivous post I show programmatic method I’ve used to check the wbgain. These gains can make the imgae more green or more blue but I can’t manage to change global luminosity.
Hope these tests could help to solve my problem.
