Abstract:
1. A data combining apparatus combining first data and second data relating to an image to form a screen comprising: a processing unit for performing predetermined processing on the first data; a data generation unit for generating the second data; a combining unit for combining the first data processed by the predetermined processing in the processing unit and the second data generated by the data generation unit; a timing information generation unit for generating timing information for the processing of the processing unit or for processing for generation of the data generation unit so that the combination of the first data processed by the predetermined processing in the processing unit and the second data generated by the generation unit is performed at the same timing; a superposing unit for superposing the timing information generated by the timing information generation unit to the first data or the second data; a timing information detection unit for detecting the superposed timing information in the first data or the second data; and a control unit for correcting a timing for processing or generation to make the processing unit or the data generation unit perform the predetermined processing or data generation based on the timing information generated by the timing information generation unit.
