A method and system for controlling operation of a fixed position camera are disclosed. The method includes determining durations of time with respect to which moving objects are projected to become at least practically out of a capture range of the fixed position camera. Based at least in part on these determined durations of time, a number of changes are made to physical settings of the fixed position camera within respective opportunity windows for achieving respective objectives, and in a priority-ordered manner.

A method according to embodiments of the invention includes creating a three-dimensional profile of a scene, calculating a relative amount of light for each portion of the scene based on the three-dimensional profile, and activating a light source to provide a first amount of light to a first portion of the scene, and a second amount of light to a second portion of the scene. The first amount and the second amount are different. The first amount and the second amount are determined by calculating a relative amount of light for each portion of the scene.

An optical structure is provided. The optical structure includes a sensor, a bandpass filter and a plurality of protrusions. The bandpass filter is disposed above the sensor. The protrusions are disposed on the bandpass filter. The bandpass filter allows light with a wavelength of 700 nm to 3,000 nm to pass through. The protrusions have a size distribution that controls the phase of the incident light to be between 0 and 2π.
