<p>PROBLEM TO BE SOLVED: To improve realistic sensation when a user views a video content.SOLUTION: A control device comprises a reference object color detection part and a spectral distribution calculation part. The reference object color detection part detects from image data, a reference object color which represents a color of a reference object representing any object in common between the image data included in a video content and a viewing space where the video content is displayed. The spectral distribution calculation part calculates a lighting spectral distribution representing a spectral distribution for controlling a luminous body from detected reference object color, a luminous body spectral distribution representing a spectrum distribution of the luminous body included in a light source of a lighting device which irradiates light in the viewing space, and a spectral reflection factor of the reference object.</p> |
