ABSTRACT:
Conversion of YUV-format data into RGB-format data is consecutively carried out through pipeline processing in two stages, namely, primary and secondary conversion which are derived from only the common expressions of theoretical conversion equations. The secondary conversion is executed by a circuit subsequent to ROMs 51a to 51c. Of the secondary conversion operation, the conversion of a G component requires complicated calculation. Therefore, analogous calculation is carried out to convert the G component.
