Abstract
A video signal receiving apparatus receives a first and second video signals for transmitting a same video content. When determining a size adjustment amount of a second video included in the second video signal, the video signal receiving apparatus performs scaling processing on a second image included in the second video signal to generate a scaling image and performs shift processing on the second image to generate a shift image. The video signal receiving apparatus calculates a similarity degree between a first image included in the first video signal and the scaling image, calculates a similarity degree between the first image and the shift image, and uses the scaling image or the shift image having the higher calculated similarity degree as an image to be subjected to the next scaling processing and the next shift processing.
