In the present invention, a measurement unit (110) measures the electromagnetic characteristics of the brain of a user. An image generator (120) analyzes the electromagnetic characteristics measured by the measurement unit (110), and on the basis of the analysis results, generates a perceptual image. A search unit (140) searches a database (130) that stores a plurality of content data pieces for content data that includes a subject image from the perceptual images generated by the image generator (120), and the search unit acquires such content data. A comparison unit (150) compares the characteristic amount of the perceptual image generated by the image generation unit (120) and the characteristic amount of the content data acquired by the search unit (140). An output unit (160) outputs the content data on the basis of the comparison results of the comparison unit (150).
