This paper extends the traditional pinhole camera projection geometry used in computer graphics to a more realistic camera model which approximates the effects of a lens and an aperture function of an actual camera. This model allows the generation of synthetic images which have a depth of field and can be focused on an arbitrary plane; it also permits selective modeling of certain optical characteristics of a lens. The model can be expanded to include motion blur and special-effect filters… 
Camera Models and Optical Systems Used in Computer Graphics: Part I, Object-Based Techniques
TLDR
The optics underlying camera models that have been used in computer graphics, and object space techniques for rendering with those models are described, and image space techniques to simulate these models are surveyed.
Introducing Vision-Realistic Rendering
TLDR
Applications of visionrealistic rendering in computer graphics as well as in optometry and ophthalmology are discussed and it is noted that the method is a post-process and can handle simple camera models as a special case.
Image capture simulation using an accurate and realistic lens model
TLDR
A digital image capture simulator that incorporates a lens model based on point-spread function (PSF) data from a commercial lens design package that has significant advantages over a simple MTF based model.
Three Techniques for Rendering Generalized Depth of Field Effects
TLDR
Generalized depth of field provides a novel tool to emphasize an area of interest within a 3D scene, to select objects from a crowd, and to render a busy, complex picture more understandable by focusing only on relevant details that may be scattered throughout the scene.
Depth of field synthesis from sparse views
Investigating Occlusion and Discretization Problems in Image-Based Blurring Techniques
TLDR
This work illustrates how image based blur algorithm needs to distinguish whether a portion of an image is either from a single object or is part of more than one object and motivates two approaches to identify objects after an image has been rendered.
Vision-realistic rendering: simulation of the scanned foveal image from wavefront data of human subjects
TLDR
A method for simulating the scanned foveal image from wavefront data of actual human subjects is developed, and methods for compositing to form a vision-realistic rendered image are demonstrated.
Image sensing model and computer simulation for CCD camera systems
TLDR
A computational model and a computer simulation system are presented for image sensing in a typical CCD camera system based on a precise definition of input to the camera system that decouples the photometric properties of a scene from the geometric properties of the scene.

TLDR
A method of using a texturing function to perform a small perturbation on the direction of the surface normal before using it in the intensity calculations yields images with realistic looking surface wrinkles without the need to model each wrinkle as a separate surface element.
