IMAGE REPRODUCING APPARATUS AND IMAGE REPRODUCING METHOD

摘要

An image reproducing device and an image reproducing method that can control a brightness and/or a contrast of a sub image according to a brightness and/or a contrast of a main image and minimize eyestrain of users are provided. The image reproducing device comprises 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 the above-mentioned first image signal; a main image signal decoding part for extracting a main image signal from the above-mentioned first image signal and decoding the above-mentioned main image signal; a brightness detecting part for detecting a brightness of the above-mentioned main image signal and calculating a brightness average value; a brightness adjusting part for adjusting a brightness of the above-mentioned sub image signal based on the above-mentioned brightness average value; an image signal composing part for synchronizing the above-mentioned main image signal and the above-mentioned sub image signal, the brightness of which is adjusted, composing them and generating a second image signal; and an image signal outputting part for outputting the above-mentioned second image signal.
