Abstract
A system and method for interpolating intensity values for a color component array are disclosed. Intensity values stored in a color component array are derived from intensity data sensed by a charge-coupled-device in a camera. First and second gradients are determined for the array elements which have no color intensity value corresponding to the color component stored in a first color component array. The gradients are used to select intensity values from the first color component array and a second color component array. The second color component array includes the intensity values for the color component which was sensed by the array element having no intensity value in the first color component array. Incorporation of intensity values of both the first and second color components reduces the likelihood of color artifacts. The method also includes determination of third and fourth gradients from the second color component array which are used to select the intensity values for the array element interpolation. An inventive system which implements the method of the present invention and an inventive arrangement of the filter elements in the color filter array is also disclosed.
