Abstract

The color photography process is studied with using test paper in the box which was possible to control with its light by fluorescent lamp and a group of different images at different intensities of light are captured (at different voltages) and calculate the power of the light system , Analysis these images and calculate the standard deviation and the mean for the intensities values for RGB bands and L the brightness component and estimate the quantity effect of the sensors of the enet web camera by changing the intensity of light of the fluorescent lamp . The relation between standard deviation although the mean for the color bands RGB and L the brightness component for the captured images with the power of illumination system .We observed rigidity and stability in distribution of the intensity of light for all color bands from (0-60) volt which the sensors of the web camera an able to sense through this range of the light voltages and observed with increasing the supplied power of the system increasing the mean value and this increase take parabola form and rigidity and stability occurred in the mean value for all color bands with continuity of increasing . Also, observed stability in the standard deviation value at low different light less than (80) volt which there wasn’t noise in this range of voltages and the noise increase at high intensities of light for the fluorescent lamp until it reach level of stability again and for all color bands RGB and L component .
