**Abstract [#z0e1578e]
-We propose a new design method for multispectral filter array based on RGB color filter array. We aim to achieve a high speed, low cost, and more precise multispectral imaging system by developing both MSFA pattern and demosaicking.

**Design of multispectral fiter array [#o9ba05e2]
-We improved the demosaicked multispectral image quality by optimizing both spectral sensitivities and spatial pattern of MSFA.

**Demosaicking of multispectral image [#ec42c20c]
-We developed some new algorithms (e.g., Multispectral Local directional interpolation, and the minimization problem of vectorial total variation) for multispectral demosaicking.

**Image compression for mosaicked multispectral image [#z725eee8]
-Since the data size of multispectral images is increased after demosaicking, we propose to encode the image before demosaicking.
