Display device and method of outputting audio signal

摘要

A display device receives first data for an object to be displayed at a first point in time and second data for the object to be displayed at a second point in time, the second point in time being after the first point in time. A controller determines a difference between the first and second data and controls output of an audio signal based on the difference. The difference is indicative of a change in perceived depth by a viewer.

1. A method of controlling a display device, comprising:
receiving an image signal and an audio signal, wherein the image signal comprises a previous frame object to be displayed on a display screen at a previous point in time and a current frame to be displayed on the display screen at a current point in time, the current point in time being after the previous point in time, wherein each of the previous frame and the current frame comprises left and right images; comparing the left and right images of the previous frame to generate a disparity map for the, previous frame; generating a first histogram from the disparity map of the previous frame; comparing the left and right images of the current frame to generate a disparity map for the current frame; generating a second histogram from the disparity map of the current frame; determining a difference value between the first histogram and the second histogram; and controlling output of the audio signal received in coorespondence with the image signal based on the difference value.
