Patent ID: 7428103

Claim:
An imaging device, comprising: an imager having a pixel cell array arranged in a plurality of rows and columns, the pixel cell array comprising: at least first, second, and third pixel cells having corresponding first, second, and third photosensors, the first and second photosensors having a first distance between each other, and the second and third photosensors having a second distance between each other, the first and second distances being different from one another, and a substantially gapless microlens array formed over the pixel cell array, the microlens array having at least first, second, and third microlenses at least two of said microlenses having respective focal points corresponding to the first and second photosensors of the pixel cell array such that photo radiation striking a top surface of at least one microlens at an orthogonal angle does not strike the corresponding photosensor at an orthogonal angle after passing through the at least one microlens, and a plurality of row and column lines coupled to the pixel cell array; and readout circuitry coupled to the plurality of row and column lines.
