| Abstract | ||
| In this study white testing image (A4 paper) has been used , it was put in a dark box with the dimensions (61 cm 74 cm 120 cm) , it has source of light (tenkisten lamp) in one of its sides and in the same side it has a hole for photographics to put the web camera (ENET) on it , in the facing side it has been put the testing image wanted to capture under different light conditions . Also it was found in the facing side of camera sensor to record the intensity of light ; then transistor the light detector of type NPN has been used . In each photographics process to measure the intensity of light . the web camera capture the white paper , we changed the intensity of light for (13) value , so we obtain to (13) images for the whit image . It recorded by computer and it analyzed via program written by the visual basic language (VB6) . It has been extracted line from the captured images from the half of high and from the half of width for each image . These lines has been studied later to limit the light homogenous and the sensitivity change process of the web camera sensor (ENET) and its affected on sensitive the homogenous with increasing light. It has been observed the web camera can not sensitive the low intensity (when the tenkistn lamp did not give sensitive light and it has been observed the arrangement in light for low intensity and stability value of the mean () with quantity (28) , the web camera start to sense in the power (0.001492 watt ) , Also ; it was found with increasing power the mean () increase and in the high intensity arrangement in the mean accord specially in the power larger than (0.005803 watt ) . the cause of changeable in the light homogenous is the oscillation in liability of light sensor in the web camera (ENET) specially in the high intensities . | ||
