Accessing the date from webcamera with pure C++. Is it possible?

mk_4

Hi, I was wondering, if it's possible to gain access to date from webcamera, connected to my PC through the USB, by using pure C++ (I mean without using WINAPI and stuff like this). I want to write an application that retrives data of images from webcamera and then works on it. If it were possible, I would be greateful if you could give me some links to sites or titles of books which broach that issue. Thank you in advance.

The Webcamera 'might' offer some API for directly controlling/accessing it - thats the c++ approach you might mean - in any case, why dont you have a look on the manufacturer's website or driverguide or such to find a driver for it .. you dont actually say what webcamera you have (which may make a difference in that someone here might have one) , are we supposed to guess ?

hmm... I don't have any webcamera yet 'cause I didn't need it so far. I've just been curious about this issue. I know, there are several ways to retrive data from webcamera by using some already existing libraries and APIs. So it doesn't metter what the type of camera it is. I'am new to c++ and just want to know if it's possible to access the driver or USB port which operates on that camera and retrive data from it but without using any api's and external libraries. I don't know if my idea is worth of effort, that's why ask about it. Maybe my previous question wasn't too strict, so sorry for that.

Yes you can use the WIA for many web cams other have there own API.

It's not exactly what I meant but anyway thanks.

I reread you question and yes It would be possible but you would have to write a driver and have some knowledge of how the webcam worked at a low level. I don't think in any of the modern OS you can have direct IO access. So if thats way you want to go I would download the driver development kit.

If it's the only way to do this, then I will rather look for some webcamera with it's own API. Anyway thank you for help.
