      In conclusion, the image formed by a pinhole camera is the convolution of the ideal (sharp) image with a pillow-case function. The difference between the convolution defined in (1) and what happens in the pinhole camera is that the points in the world are not neatly arranged onto a rectangular grid, as are pixels in an image, but form a ...
