This type of arrangement is found in digital cameras. The response of each sensor is directly equal to the amount of light or (photon) energy striked on the surface of the sensor. Generally, in this stage, pre-processing such as scaling is done. Image can be defined as a function which as two dimension value of magnitude of image and these value works for making of elements of digital image. Two pixels p and q are said to be connected in S if there exist a path between them consisting entirely of pixels in S. For any pixel p in S the set of pixels that are connected to it in S is called connected component of S. If S has only one connected component, then it is called connected set. It forms core research area within engineering and computer science disciplines too. Motion perpendicular to the strip provides imaging in other direction. is blue, b is green, and g is red Most of the cones are at the fovea.
