摘要
A system for transcoding signals for a 12x10 dot matrix into signals for a 8x10 dot matrix uses a two phase conversion process. In the first phase, the pixels of each line are arranged in groups of three and in their natural order. Each group of three pixels is logically processed to obtain a group of two converted pixels. In the second phase, the configuration of the initial four pixel block which straddles the limit or interspace between two three-pixel groups are analyzed. Depending on the difference found during the analysis, the two pixels which are converted in the first phase are kept on either side of the limit, or are replaced by either the corresponding converted pixels of the former line or the pixels that are calculated in the second phase.
