A developing method of computer microscopy called Fourier Ptychography can provide images of samples at a gigapixel resolution. An important tradeoff between a microscope's resolution and field of view is addressed by Fourier Ptychography without the need for any moving parts, merely requiring a reconstruction program and the attachment of an LED array to a standard digital microscope. This paper explains the ptychographic imaging, extended ptychograhic imaging, and incoherent imaging and hence discusses the result obtained from these methods on cameraman image.
