1. A vehicle system, comprising:
- at least one lens configured for light sensing applications and further configured to project two or more spatially interdispersed images of a scene upon an image plane of an image sensor, wherein said two or more spatially interdispersed images are configured as a function of a patterned spectral filter positioned between said lens and said image sensor and wherein said at least two spatially interdispersed images are vertically and, or, horizontally misaligned with respect to one another, and each of said spatially interdispersed images pass through a different color of said spectral filter to fall on a pixel array, such that alternate spots of said spatially interdispersed images fall on like portions of said pixel array except that said colors of said spectral filter are reversed.

14. A vehicle system, comprising:
at least one lens configured for light sensing applications and further configured to project first oriented light rays associated with a scene to form two or more spatially dispersed images of the scene on an image plane of an image sensor, wherein a portion of said two or more spatially dispersed images overlap one another, and a portion of said two or more spatially dispersed images that are not overlapping pass through a different color of said spectral filter to fall on a pixel array, such that alternate spots of said spatially dispersed images fall on like portions of said pixel array except that said colors of said spectral filter are reversed. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
