The process of scrutinizing the brightness of each element of detail contained in the image of a scene to be transmitted by television. The television scene is sampled many times per second in order to create a sequence of images (called frames). Then, within each frame, sampling is done vertically to create scan lines. Scanning proceeds sequentially, left to right and top to bottom.
