Abstract
The present disclosure relates to an image sensor including a plurality of pixels formed in and on a semiconductor substrate and arranged in a matrix with N rows and M columns, with N being an integer greater than or equal to 1 and M an integer greater than or equal to 2. A plurality of microlenses face the substrate, and each of the microlenses is associated with a respective pixel. The microlenses are arranged in a matrix in N rows and M columns, and the pitch of the microlens matrix is greater than the pitch of the pixel matrix in a direction of the rows of the pixel matrix.
