is there any possibility to control expusire time with USB-cameras?
I'm taking pictures with a USB camera using Scilab and IPCV:
n = camopen(0); sleep(200); im = camread(n); //get a frame imshow(im); camcloseall();
This works very well. However I can not controll exposure time. The camera can be controlled with a camera-software and settings can be stored in the camera. After restart of the camera, the settings are still there. When using scilab, it looks that the image is taken with a different setting. Does scilab with above mentioned camopen and imread send different settings?
