Abstract:
1. An image sensing device having an array of image sensors and a filter structure disposed in relation to the image sensors, the filter structure comprising blocks of filter groups, each block of filter groups being arranged in a repeating pattern adjacent to one another, each block having a filter group comprising a combination of one or more areas adapted so as to allow light to pass therethrough onto corresponding image sensors with colour filtering, and one or more areas adapted so as to allow light to pass therethrough onto corresponding image sensors without colour filtering, wherein said one or more areas adapted so as to allow light to pass therethrough onto corresponding image sensors with colour filtering comprise two colour filters, wherein said one or more areas adapted so as to allow light to pass therethrough onto corresponding image sensors without colour filtering comprise four filterless areas or non-colour filters, wherein the filters are arranged such that in each repeating and adjacent filter block there are two colour filters for every four filterless/non-colour filters.
