Hello people,

Is it possible to use the camera flash with PyCamera (from Nokia Research) ?

Hi Luis,


I'm Rafael from the Code Camp in Rio. I'll still talk in English here, so the others can also understand


So, I'm not sure if you can do that using PyCamera, but you should, since is a extending module and it wouldn't miss such a basic function.

Although, there is a very complete example on the Wiki that doesn't says anything about using flash

I'll search a little more tomorrow. I'm also curious about this

If I find something, I will post it here.


BR,

Rafael.

Just downloaded the PyCamera package and saw the oficial script that comes in the documentation folder (by the way, is the same from the Wiki). I think it really doesn't have support for using the flash, since it isn't any example of that, even in official documentation.

Unfortunately, I think you will have to use default camera module for using flash

Manual 1.4.4 page 35:

flash is the flash mode setting. The default value is 'none'. The following
flash mode settings are supported:
- 'none'
No flash. Default value, always supported
- 'auto'
Flash will automatically fire when required
- 'forced'
Flash will always fire
- 'fill in'
Reduced flash for general lighting
- 'red eye reduce'
Red-eye reduction mode

Cheers,

Hello JOM,

Thanks for the reply, that documentation is for the standard camera module, and not the pycamera from NRC.

Hi Luis,

Yes, you can use flash !

Below are the modes,

EFlashAuto , EFlashFillIn,EFlashForced , EFlashLManual , EFlashRedEyeReduce , EFlashSlowFrontSync , EFlashSlowRearSync, EFlashNone

and here is how you can select one,

cam = pycamera.Camera(0)
cam.SetFlash(EFlashAuto)

Hello croozeus,

I've already tried to use SetFlash, but I get an error saying that this method doesn't exist.

Is the function listed when you use, dir(cam) ?

Yes, and hence the error!

Ideally it should be listed. I haven't used PyCamera myself. Lets wait for someone who has used it, to comment on this.

I guess the source is not available either, so we are unable to modify it ...

[Rafael T.]

Here it is also giving this error. And when I do dir(cam) it also doesn't return any set flash function

Ok, now I know what you were talking about
http://research.nokia.com/research/p.../download.html

Checked only PyCam and at least there was only _pycamera.pyd without sources. Not sure what was used to create it, but maybe those other ZIPs contain something useful... Most likely not the needed sources.
