2013-03-01 02:35:03 -0600	asked a question	OpenCV and Android NDK - setting camera Exposure Hi, I'm having problems setting camera propertie EXPOSURE.. This is my code: vt1->capture = cvCaptureFromCAM( CV_CAP_ANDROID + vt1->cam_device); cvSetCaptureProperty(vt1->capture, CV_CAP_PROP_EXPOSURE, -2); but if I print out camera EXPOSURE like this: LOGI("EXPOSURE = %d", cvGetCaptureProperty(vt1->capture, CV_CAP_PROP_EXPOSURE)); it doesn't give me "-2", it gives me "0". Is it possible that camera manufacturer made it impossible to change exposure settings? It is possible to change exposure from built-in camera application, but I can't do it through OpenCV. Device is HTC ONE X
