AN IMAGE SENSOR COMPRISING AN ARRAY OF PIXELS FOR REDUCING THE SHADOWING EFFECT, AND CORRESPONDING DESIGNING METHOD AND COMPUTER PROGRAM PRODUCT

摘要

The present disclosure relates to an image sensor (21) comprising an array of pixels, wherein a set of pixels of the array comprises pixels with different height levels arranged according to their height level and relative position to an optical axis (22) of the image sensor, wherein each pixel of the set can take one height level i among N different height levels, N≥2, where i=1 is the smallest height level and i=N is the highest height level. According to the disclosure, for a pixel of the set having a first height level equal to n, 2≥n≥N, and an adjacent pixel of the set having a second height level equal to m, lower than the first height level, in at least one of horizontal, vertical, or diagonal scanning direction, from a point at which the optical axis (22) intersects the image sensor (21) to at least one rim of the image sensor, the second height level m is equal to n−1.
