Object → Optics → Sensor → Digital data → Algorithms

Optics defines what information can enter the system:)

Sensors convert light into data!

Computation reconstructs or enhances the data.

Computational imaging ≠ software tricks

Thin lens equation : 1/f = 1/z_o + 1/z_i

f : focal length

z_o : object distance

z_i : image distance

Magnification M = - z_i/z_o

Aperture = opening controlling light intake(조리개 같은 느낌이네 빛의 양을 조절할 수 있게 하는!) → objecct

f-number = f/n = f/D
