摘要： A terminal transmits disk identification information and user information to a content delivery server for purchase of initial content in the case where the content to be stored in an optical disk is provided to a user. The user information and the content delivered by the content delivery server are written on the optical disk. The optical disk storing the initial content is set in the terminal for purchase of additional content. The terminal transmits, to the content delivery server, disk identification information, the user information and content information. The content delivery server determines whether or not the purchase of the additional content is authorized. When the content delivery server determines that the purchase of the additional content is authorized, the content delivery server delivers the additional content to the terminal. The terminal writes the additional content on the optical disk. It is therefore possible to prevent content from being copied and obtained in an unauthorized manner and provide content based on preferences and characteristics of the user.

摘要： A change in the white balance caused due to the temperature is reduced in an image display device using MEMS and a laser light source. An image processing unit of the device superposes a signal based on a first measured value of a light quantity at a first temperature on a image signal to be supplied to the laser light source. An amplification factor of the light source drive unit is changed so that a second measured value at a second temperature comes close to the first measured value at the first temperature as a target value based on the second measured value at which the light quantity of light generated at the laser light source is measured at the second temperature different from the first temperature on the signal based on the first measured value.
