IMAGE SIGNAL GENERATING APPARATUS, IMAGE SIGNAL GENERATION METHOD, COMPUTER PROGRAM, AND RECORDING MEDIUM

摘要

An image signal generating apparatus is provided. The apparatus includes a sight-line detecting unit, a peripheral image determination unit, and an image processing unit. The sight-line detecting unit detects a sight line of a user looking at images of a plurality of contents displayed on a display unit. The peripheral image determination unit determines an image located in a user's peripheral viewing field as a peripheral image in the images of the plurality of contents based on the sight line detected by the sight-line detecting unit. The image processing unit adds an object representing an attribute of a content of the peripheral image determined by the peripheral image determination unit to an image signal for displaying the images of the plurality of contents.
