dear sir

i am using imagingcontrol 3.0 trial version with vb.net 2003...i am using this with pixelink pl-a653 imaging module.......i wanted to measure the intensity of inoming image....image having a bright spot of 10 pixel diametrert on the black background....i set exposure time of camera very low in order to detect the only bright spot .....is it possible to measure the intensity of image .....i have one approach....first save the incoming image as bitmap and the calculate the brightness of image by adding the bightness of each pixel of image using vb.net properties of bitmap "brightness" and finally divide it by total number of pixel because brightness value is between 0 and 1 ...is it correct way to do this....

please give me ur suggestion

with regards
