Apparatus and method for combining background images with main images

摘要

It is intended to enable main image data from a video camera and background image data recorded on a recording medium to be chromakey-combined with each other naturally at a low cost. When a video switcher chromakey-combines main image data that is produced by imaging with a video camera with background image data that is reproduced from a magnetic tape by a VTR, the main image data is chromakey-combined with the background image data such that the VTR is caused to perform a reproducing operation on the magnetic tape based on time codes that are stored in a control device as one of a pair of information and the operations of the video camera and a video camera stage are controlled based on camera control information as the other of the pair of information.
