Abstract: An image sensor for acquiring an image of an object comprises: an array of photo-sensitive areas (112); and a mosaic filter (114) associated with the array dividing the array into sub-groups (118) of photo-sensitive areas (112) extending across at least two rows and two columns, wherein the mosaic filter (114) transmits unique light properties to the photo-sensitive areas (112) within the sub-group (118); wherein the mosaic filter (114) comprises a sequence of unique filter portions associated with a set of photo-sensitive areas (112) along a row, wherein the set extends through more than one sub-group (118); wherein sequences comprising the unique filter portions are associated with each row and wherein the sequences associated with adjacent rows comprise different orders of the unique filter portions, such that different light properties are transmitted to photo-sensitive areas (112) in the same column of adjacent rows.
