Auto exposure (gain), auto white balance switching does not work in freenect-glview example

[alexander-hagg]

In v0.2.0 you added control of auto exposure and white balance, as mentioned in #332. I am running the current main branch. After starting the freenect-glview example and then consecutively pushing 'e', 'b', 'e, 'b', I get the following output, but no change in device behaviour. I flip my lights on and off, but autoexposure still seems to be on.

'w' - tilt up, 's' - level, 'x' - tilt down, '0'-'6' - select LED mode 
'f' - change video format, 'm' - mirror video, 'o' - rotate video with accelerometer 
'e' - auto exposure, 'b' - white balance, 'r' - raw color 
read_cmos_register: 0x0106 =>
write_cmos_register: 0x0106 <= 0x7fff 
read_cmos_register: 0x0106 =>
write_cmos_register: 0x0106 <= 0x02
read_cmos_register: 0x0106 =>
write_cmos_register: 0x0106 <= 0x00
read_cmos_register: 0x0106 =>
write_cmos_register: 0x0106 <= 0x00
read_cmos_register: 0x0106 =>
write_cmos_register: 0x0106 <= 0x4000
read_cmos_register: 0x0106 =>
write_cmos_register: 0x0106 <= 0x02

Confirmed!

Now I'm not so sure. I don't see a difference when toggling e and b, but my output is consistent with the correct bit being written to the cmos register. Here I pressed e four times:

read_cmos_register: 0x0106 => 0x648e
write_cmos_register: 0x0106 <= 0x248e
read_cmos_register: 0x0106 => 0x248e
write_cmos_register: 0x0106 <= 0x648e

43d44e9 prints the read_cmos_register reply. It would be helpful if you can post the output with e four times then b four times.

[alexander-hagg]

This is the output on my system, pressing e four times, then b four times.

read_cmos_register: 0x0106 => 0x7fff
write_cmos_register: 0x0106 <= 0x7fff
read_cmos_register: 0x0106 => 0x0000
write_cmos_register: 0x0106 <= 0x00
read_cmos_register: 0x0106 => 0x0000
write_cmos_register: 0x0106 <= 0x4000
read_cmos_register: 0x0106 => 0x0000
write_cmos_register: 0x0106 <= 0x00
read_cmos_register: 0x0106 => 0x0000
write_cmos_register: 0x0106 <= 0x02
read_cmos_register: 0x0106 => 0x0000
write_cmos_register: 0x0106 <= 0x00
read_cmos_register: 0x0106 => 0x0000
write_cmos_register: 0x0106 <= 0x02
read_cmos_register: 0x0106 => 0x0000
write_cmos_register: 0x0106 <= 0x00

I'm kind of stumped on this one. The first read from my model 1414 is always 0x648e. What model do you have?

[alexander-hagg]

It is a 1473 model

And by the way, I did a manual install (using http://openkinect.org/wiki/Getting_Started#Ubuntu_Manual_Install) to get the Kinect model to work with Freenect.

Hey, has this issue been resolved? Can we control the exposure, colour correction and white balance of the kinect with the latest release?

[Masterxilo]

I think exposure, white-balance and colour correction can only be controlled with "Kinect for Windows" devices, not with vanilla XBox 360 devices.
