Hi all !
I got my hands on the Canon SDK and wrote a little app for remote-capturing images. By now it has live-preview via USB, full resolution capturing, one level of onion-skinning and of course a possibility to review the already captured frames.
I’m going to add the following features: autofocus-lock (a shame manual focus isn’t possible remotely), macro-mode-switch, multilevel-onion-skinning and playback at constant (selectable) framerate. It won’t be an all-in-one solution, only for frame capturing (no sound or colour-keying or whatever, there are better tools for that)
Currently, I tested it with my A520, but nearly all Powershots should work.
Anyone interested ?
To get CSMC, look here… (free download)April 4, 2006 at 1:18 pm #175282
Yes, it’s for windows. The SDK is available for windows only… using it is quite simple actually, you have a function to ‘connect’ to the camera and put it into remote-capture mode. Then you have another function to activate the live-feed. That comes in standard windows-DIB-format, so you only need to bitblt it to the screen… Screenshots follow when I get back to my development-pc 😉
BTW – you can’t attach images to posts here, can you ?April 4, 2006 at 1:27 pm #175283

I made a screenshot.
The live-feed looks horrible compared to my QC4000, but the captured frames are ok. The bad thing is you have to rely on the autofocus and have no chance of knowing wether the cam got it right or not before shooting a frame. But once you have it focussed as you like, you can lock the af. You can’t save or restore it though, so you have go thorugh one scene without powering off the cam or disconnecting. Not that bad actually, but a limitation…
The “new” and “load” buttons on the left are greyed out because they are only available until one of them is pressed. Once everything is in there I think of changing the layout of the controls to tab-panes. One for new/load/save, one for capture-mode, one for playback/editor-mode.
No comments about the crappy blue-screen, pleasse 😉April 5, 2006 at 1:35 pm #175557

The only feature you cannot use manually while in remote mode is the focus, and you can still lock it to make sure it stays as it is. This is unfortunate but still acceptable. The problem is that this is not the software’s fault but the camera’s. It would be so much cooler if you could change the focus from the computer, making possible automated focus pulls, e.g.

There don’t seem to be many cameras that comply to a standard in this regard. A standard would be PTP (Picture Transfer Protocol), which many cameras support – but only for downloading images. A camera that is said to support PTP is not automatically remote controllable over that protocol and the commands sent to the Canon cameras on top of PTP seem to be Canon specific. Also, I don’t think I have ever before had a camera that can send the viewfinder image over USB. This doesn’t seem to be a wide-spread feature from my experience. But as the usual spec sheets and reviews don’t often tell us these things, I don’t know for sure.
