To reduce cost, current digital cameras adopt color filter array (CFA) instead of RGB camera which obtains beam splitters to capture image information. This leads effect that only one of three color channels remains and the other two color channels are missing during CFA. To compensate missing color information, color interpolation or demosaicking process is needed. There have been many methods with different degree of complexity and filter size. Normally bigger filters and higher complexity provide better performance. However, clever method may give fast and satisfactory results in terms of objective and subjective performance. This paper proposes adaptive camera image interpolation method which uses directional information. Simulation results show that the proposed method outperforms conventional benchmark method.
