1. A method for enhancing the performance of an imaging device, comprising the steps of: (1) receiving first and second input pixels having an initial intensity value, the first and second input pixels being obtained by an imager having a fixed focal length; (2) forming a first intermediate intensity value from the first input pixel based on the initial intensity value of the first input pixel and the value of a first weighting factor; (3) forming a second intermediate intensity value from the second input pixel based on the initial intensity value of the second input pixel and the value of a second weighting factor; and (4) combining the first and second intermediate intensity values to form an output pixel.
