1. An optical sensor, comprising:
a pixel matrix, comprising a plurality of unblocked pixels, a first pixel and a second pixel, which is arranged at a side of the first pixel in a row direction of the pixel matrix; and
an opaque layer, covering upon a first region, which is a part of the first pixel, and upon a second region, which is a part of the second pixel, but not covering upon the unblocked pixels, wherein the first region and the second region are symmetrically arranged in the row direction, and uncovered regions of the first pixel and the second pixel are arranged to be larger at a pixel edge than at a pixel center in a column direction of the pixel matrix, wherein
the first pixel and the second pixel are arranged in a first row of the pixel matrix,
the pixel matrix further comprises a third pixel and a fourth pixel arranged in a second row, separated by one row of unblocked pixels from the first row, of the pixel matrix,
the opaque layer further covers upon a third region, which is a part of the third pixel, and upon a fourth region, which is a part of the fourth pixel, and
the third region and the fourth region are symmetrically arranged in the row direction.
