Mixer-systems comprising gain-blocks and switches have a flexibility depending upon their configuration and are made more flexible by supplying data input signals to the gain-blocks and oscillation signals to the switches for switching couplings between the gain-blocks. A sensitivity uniformization section uniformizes the sensitivities of pixels of a color and sensitivity mosaic image to produce a color mosaic image, and a color interpolation section interpolates color components of the pixels of the color mosaic image M to produce output images R, G and B. An encoding method may include encoding an input bit stream to generate first bit streams of C-bits, and receiving the first bit streams and shuffling data of the received first bit streams to generate second bit streams. The node application loadsunloads selected applications and manages node resources for those applications.
