Abstract
An image reproducing device includes: an image signal inputting part for receiving input of a first image signal; a sub image signal generating part for generating a sub image signal from information on a sub image extracted from said first image signal; a main image signal decoding part for extracting a main image signal from said first image signal and decoding said main image signal; a brightness detecting part for detecting a brightness of said main image signal and calculating a brightness average value; a brightness adjusting part for adjusting a brightness of said sub image signal based on said brightness average value; an image signal composing part for composing said main image signal and said sub image signal, the brightness of which is adjusted, and generating a second image signal; and an image signal outputting part for outputting said second image signal.
