| Abstract | ||
| In this research imaging a color image using a camera laptop type DEL VOSTRO (WEBCAB OPTIMIZED) in an open room windows with different lighting (natural lighting once and natural with electric again) a number of microscope glass slides identity of type Cover Glass where placed in front of the camera, which is intended to take images of the scene placed on the different dimensions of the camera (125,100,75,50) cm. The techniques Calculates contrast (horizontal and vertical) was adopted to image with different lighting, to evaluate resolution image through the statistical properties of the image (average and standard deviation). The results show that the techniques adopted to calculate the contrast (vertical and horizontal) was standards for the efficient evaluation of image quality and lighting effects. Also the presence of a number of glass slides between the camera and image affect the contrast of the images taken and this evident, and this process has been proven by the camera and computer simulation. ا | ||
