发明名称 Colour picture transmission processing apparatus
摘要 The apparatus includes a computing unit for counting the number of colours as the numbers of different colour pixel values during scanning pixels of colour picture data for each row. A palette forming unit is provided which has a storage area for representative colours of a preset number of entries. A subtractive colour palette is formed by storing full colour pixel values as representative colours in the entries when the number of colours is counted upwardly. A transmission format discrimination unit counts the number of transmission pixels to the end of a previous row, if the number of colours exceeds a preset number of entries of the subtractive colour palette. Transmission data according to the full colour format of the number of the transmission pixels are compared with transmission data according to the palette format. Data transmission is instructed according to the format of a smaller transmission data amount. A data transmission unit forms and transmits the palette format data which include halftone codes and representative colours of the subtractive colour palette if an instruction of a data transmission in the palette format is received. Full colour format data are formed and transmitted including colour pixels, when an instruction of data transmission in the full colour format is received.
