Abstract

Apparatus and methods for enhancing the performance of an imager in applications such as gaze tracking are described. An enhanced image sensor includes a sensor pixel array, a filter array optically coupled to the pixel array and a filter map including data associated with one or more characteristics of the filter array. The filter array characteristics can be preconfigured and/or dynamically reconfigured to allow for wavelength specific pixel capture, with the filter map correspondingly adjusted in response to changes in the filter array characteristics.
