Video signal processing apparatus and video signal processing method

A video signal processing method, comprising the steps of:

• outputting a standard video signal and an enlarged region video signal to a display portion for displaying thereon an image when first and second cameras each having an image pickup element including an effective image region for output of the standard video signal, and an enlarged region wider in horizontal and vertical directions than the effective image region, outputting the standard image signal from the effective image region, and outputting the enlarged region video signal from the enlarged region transmits the standard video signal in accordance with a predetermined transmission format with which the standard video signal and the enlarged region video signal are transmitted, and superimposes the enlarged region video signal on each of a vertical blanking interval and a horizontal blanking interval of the predetermined transmission format, thereby transmitting the resulting enlarged region video signal;
• outputting a manipulation signal in accordance with which a shift between optical axes of images captured by using said first and second cameras, respectively, is adjusted based on the image displayed on said display portion in accordance with the standard video signal;
• and
• moving a region of the standard video signal so as to correspond to the shift between the optical axes within a range of the enlarged region video signal when the shift between the optical axes is adjusted in accordance with the manipulation signal, extracting the standard video signal corresponding to a movement from the enlarged region video signal contained in a range of the movement, and outputting the standard video signal thus extracted.
