Abstract:
1. A method of processing image data generated according to a color filter array, comprising: generating horizontal and vertical classifiers from the image data; directional-interpolating a predetermined color component from the image data depending on the classifiers to generate a directional-interpolated color component, wherein the predetermined color component is determined from a selected one of a row of the image data or a column of the image data depending on which of the horizontal classifier and the vertical classifier is greater; and generating chrominance components from the directional-interpolated predetermined color component and image data for at least one other color component aside from the predetermined color component, wherein the directional-interpolated color component has a value of a horizontal convolution current if the vertical classifier is greater than the horizontal classifier, a value of a vertical convolution current if the vertical classifier is less than the horizontal classifier, and an average of the values of the horizontal and vertical convolution currents if the vertical classifier is equal to the horizontal classifier.
