hi-res camera control
« on: Jun 14th, 2004, 5:10pm » |

I'd like to use Processing to make a small time-lapse film. I know it wouldn't be difficult to do with any old webcam, having processing save still images at some specified interval. However, I'd like to do it with high resolution images (about 1024x768 would be fine) so that I could pan around the frame for the finished result. Are there any webcams out there that let you capture images at this resolution? Are there any not-too-difficult ways to hack a digital still camera so that its shutter can be triggered over USB or something? I have a Sony DSC-S75. Thanks.

well this has nothing to do with Processing but if you're on a Mac you should check out iStopMotion: http://www.istopmotion.com/
This allows you to take shots from a video camera every so many seconds to do time lapse/stop motion animation. Not sure the resolution can go up as high as you want though.
Of course if you're not on a Mac my answer is totally useless.

I have also been looking into ways of getting hi-res images into processing. I have been playing around with the Logitech Quickcam pro 4000. It is capable of capturing still images of 1024x768. This is done in the Logitech ImageStudio either directly from the program or by pressing the small button on top of the camera. So I guess you could do some ugly hardware hack where the button is activated say every second. And then you just access the images from processing in the folder where they are stored as Picture1 Picture2 etc.
Of course it would be a lot nicer if you could control the camera capture directly via the usb from processing. According to thread JMF in Java supports the Quickcam pro 4000

In the thread they also link to an SDK for the camera. I found a java test program

I haven't had time to test it yet but I will post the result here when I have.

well, I tried the testprogram. But the JMF only support capture up to 640x480.
I also contacted logitech's support, to find out if there was a way to do hires capture from other programs than the logitech software. Unfortunately logitech doesn't want to give out any info on how to do this, so you have to use their own software. They have also discontinued the SDK for the logitech cameras.......so not much help there. I guess it is back to my nasty hardware hack
