Image processing apparatus for discriminating and processing different formats of color image signals

摘要

Data processing apparatus include an input device that has a single signal line. The input device inputs a data signal and a discrimination signal through the signal line with the data signal having one of a plurality of data formats in each of which a plurality of kinds of data are arranged during respectively different periods of the data signal. The discrimination signal represents the one of the formats in which the data signal is arranged. A discriminator, connected to the single signal line, is responsive to the discrimination signal to discriminate the format of the data signal input by the input device. A separation circuit is responsive to the discrimination by the discriminator to respectively separate the plurality of kinds of data from the data signal in accordance with the format of the data signal. The different kinds of data carried by the data signal may include different color component data. Further, the formats in which the data signal may be arranged include an arrangement of the different kinds of data in pixel units, an arrangement of such data in line units, and an arrangement of such data in frame units.
