Night Vision Camcorder - Possible?
 

Hey guys just want to know is there anyone out there planing on writting an app for the video camera to recording night vision video?

I've used the SONY camera came with Carl Ziess and I got to say Night vision works great with just a red light beaming out.

Is this ever be possible on N900? Since N900 got redlight LED and a good lense

Re: Night Vision Camcorder - Possible?
 

The Sony uses infra-red light for night shots, I'm fairly sure the N900 doesn't have one.

Re: Night Vision Camcorder - Possible?
 

well, n900 has ir port.... but it is useless.

and sony's led is probably much more powerful than n900's.

Re: Night Vision Camcorder - Possible?
 

By default, any camera can record in night-vision: The ccd is based on silicon and works fine with wavelength up to 1100nm. But you have to remove the IR filter, and supply enough illumination in the IR region. (and maybe you need to filter out uv-vis!). For sure you can find some nice hack tutorial for digital cameras, and you can buy cheap IR leds, but I don't know if I would open my phone... anyway, awesome idea...

Re: Night Vision Camcorder - Possible?
 

Of course it's useless!! IR port is not a camera!! nor an illuminator!! And Sony led has probably a different wavelength. Or can simply be a double one with red+IR. Btw the problem isn't the led but the filters you might remove.
so, if someone has IR leds, can I suggest to try to get some pics? so we can see how much we need to fight for removing the filter.

this is what you should expect with a standard digital camera hacked:
(a friend did this)

That's freaky!! :eek:

Re: Night Vision Camcorder - Possible?
 

wtf, what have you been smoking? usually phone cameras register wavelengths of remotes so the ir port is a potential ir source for night vision stuff invisible to human eye.

Re: Night Vision Camcorder - Possible?
 

It's pointed in the wrong direction and way too weak for illumination, though :P

Anyone with a strong external IR illuminator care to try taking a few pictures?

Re: Night Vision Camcorder - Possible?
 

yup! sorry... I tought you planned to acquire from the ir port. but of course ir port has no resolution for acquiring :)
btw the same guy that take this pic has an n900 now, so I texted him asking if has already tried. waiting ...

Re: Night Vision Camcorder - Possible?
 

My mate hasn't tried, couse "you must remove the filter, and it's still brand new...". I don't know anyone else in the field...

Re: Night Vision Camcorder - Possible?
 

so seems like imposible to hack the camera via software

Re: Night Vision Camcorder - Possible?
 

Take a look in the new user manual (which suggests new features for PR1.2) - It includes night modes for video and photo.

FYI,night mode is not night vision. Two complete different things. Night vision using infrared light and night mode using algorithm and sensoring

Re: Night Vision Camcorder - Possible?
 

Oops, my bad, misread.
I am waiting for night mode for a long time, I thought I am making someone else but me happy that it's coming :)

Re: Night Vision Camcorder - Possible?
 

Night mode can be handy but the frame drop really bad in this mode and very grainy. It won't be perfect though, take a look at Lanscape Mode for picture mode, so blurry and unusable. Automatic and Macro is the only thing that work.

I uses the N95 lanscape mode and yes was clear like a normal automated focus. N900 camera is far from finishing.

Re: Night Vision Camcorder - Possible?
 

Well, It's still a cell phone, or tablet computer, I don't expect it to excel in all the features - But i'll give you an example why I need night mode.

Warning, Offtopic :
I was with some friends at a bar, someone left a bag full of crap outside, the police came, closed the whole area down, and brought a robot to take care of the bag - open it, blow it up etc.
Now, the police where I live are known to do things only to 60% extent.
They used the robot the open the bag (tear it apart) while spreading around everything that was in it, just making sure no bombs etc, and they left it on the road, blocking traffic, leaving the place messy and dirty with someone belongings ripped and tossed everywhere. This is prime news to some local news website.
If My N900 could photo that at night mode, the framerate wouldn't matter, and also the graininess wouldn't matter.

I don't carry a real camera with me. I got enough things to carry around.

Re: Night Vision Camcorder - Possible?
 

is it possible to light up the camera leds one by one?? sow youj could replace one of them with a ir led... i would do the hack if its possible...

Re: Night Vision Camcorder - Possible?
 

Night mode will just slow the shutted speed down, you'll have to hold extra still or put the phone on a stable surface.

When those modes are built into camera phones (unless you can control the sesnors shutter speed and ISO) its never much good for more than a slightly less blurry upclose photo of your drunk friends (ie no distance involved).

Re: Night Vision Camcorder - Possible?
 

IR shooting is impossible. It is blocked by special physical filter in camera. It is needed for correct white balance in visible range. Cameras from Sony can mechanically remove it and use IR light, more light. IR flash is not important, more light is important.
It is possible to make IR shots with usual camera without removing filter, by adding black filter. But then you have get 10-12 steps darker images, so this is not suitable for night shooting.

Night mode in n900 just means, that now you can shoot crap at night. It allows you to set very high ISO and long exposure which would result in very noisy and blurred image.
