In most of the digital cameras, single sensor cameras are used for image acquisition with a color filter array (CFA). But these images are saved in unrefined format still. These are going to further process to become color images. This becomes a reason for noise generation in images. Noise is very to remove. Numbers of technique are used to denoise the captured images but because of various limitations, techniques are not up to the mark. In this work, we introduce a technique which gives the satisfactory result. In this technique, 2D image is converted into High pass and Low pass component then denoised the high pass component and further merge with the low pass component again. Now it is required a demosaicking process. A directional LMMSE demosaicking process is used. To estimate the system performance different parameters is used such as SNR and visual quality.
