A method of receiving optical channels including providing an optical band filter configured to filter at least one optical channel from a multiple channel optical signal and provide a band filtered optical signal. Each TRC accounts for colorant interactions between a primary colorant with which the first color separation is to be rendered and at least one secondary colorant with which at least a second of the plurality of color separations is to be rendered. The network is preferably inserted between a source of laser modulating signal and the laser. A source electrode layer and a drain electrode layer are formed over the gate insulating layer. This model limits the exploration of the Virtual Memory organization considerably without limiting the optimization possibilities. The pattern-detection method has steps of binarizing the input image data to obtain binary image data, recognizing a partial image that is contained in the binary image data, is part of the specific pattern, and has an empty inside, and determining the specific pattern contained in the image based on the recognition results.
