Objectives
1. Rays to pixels
2. A camera without optics
3. Lens in the camera system
4. The lens equation
Context of computational photography
3D scene, illumination, optics, sensor, processing, display, user
Rays -> pixel
optics, sensor, image processing, computer graphics, computer vision
Scene via a 2D array of pixels
rays are fundamental primitives
illumination follows a path from the source to the scene
computation can control the parameters of the optics, sensor and illumination
ViewFinder
Focus or Zoom Ring
Shutter Release
Frontal Glass Lens
Diaphragm
Photographic film
Focal Plane Shutters
Pinhole photograph
-heoretically
no distortion straight lines remain straight
infinite depth of field: everything in focus(but there is optical blurring)
