A camera control technique is provided. An image data processing apparatus includes a raw data processor configured to convert a signal collected by an image sensor into a digital signal, an identification information processor configured to allocate identification information to each video frame obtained by the raw data processor, and a metadata processor configured to write the identification information in metadata of the video frame. Video frames can be captured with different frame rates. The identifcation information includes at least one of a time stamp and a frame counter. Based on this identification information missig video frames or video frames being reversed in order can be detected. Afterwards, the order of video frames can be corrected or a missing video frame can be re-inserted by copying eiher the preceding or the subseqent video frame.
