Patent ID: 7301570

Claim:
A camera comprising: a sensor composed of light-sensitive elements arranged in a matrix and sensitive to light within an image spectrum; at least a first filtering device for processing the signals issuing from said sensitive elements, comprising a plurality of linear filters for supplying a respective plurality of output signals, each linear filter acting upon signals from a different plurality of selected light-sensitive elements arranged along a line with respect to the sensor and selected based on the respective positions of the selected light-sensitive elements with respect to a particular light-sensitive element; an elimination device for classifying output signals of the linear filters relative to each other, for identifying extreme output signals of one or more linear filters that are either greater than or less than output signals of all other linear filters whose output signals have not been identified as extreme output signals, and for eliminating the extreme output signals; and an estimation device for supplying an estimated image value for the particular light-sensitive element produced by combining a plurality of remaining output signals not previously eliminated as being extreme output signals.
