Abstract
An image taken from a typical camera loses its intensity and contrast around the periphery due to optical attenuation. A model is derived to characterize this effect quantitatively. This model is derived for a commonly used thick lens using the sine condition, and thus, is more general than those from the Gauss geometrical optics. Based on this model, the authors developed an algorithm to calibrate the periphery attenuation. Some experimental results are presented
