Filtering circuit, filter processing method, image pickup element circuit and camera

摘要

A filtering circuit which filters an image picked up by an image pickup element arranged in a two dimensional array. The filtering circuit includes a plurality of filtering units and a selecting unit. The plurality of filtering units locally filter a plurality of pixels forming the image, and the selecting unit selects one or more pixels to be filtered by one of the filtering units and selects another pixel to be filtered by another one of filtering units. The selected one or more pixels filtered by the one filtering unit and the selected another pixel filtered by another one of the filtering units belong to a same column in the two dimensional array.
