What is computational photography?

The so-called computational photography is actually a new discipline, which contains many forms of realization. Our simple understanding is that the generation of photos is no longer absolutely dependent on the professional photography knowledge of image sensors and photographers, nor on the pressed shutter, but the role of chip hardware such as mathematical algorithms and CPU is more important. For example, the results of several kinds of computational photography mentioned above are the results of combining multiple photos or even photos taken by different cameras by mobile phone programs and algorithms. The user just clicked the shutter and didn't know what the algorithm had done. He only knows that the photos he took are more striking-what you see is what you get.
