A remote control device is provided which is of a relatively simple configuration and capable of remotely controlling a digital mirror apparatus or the like. The remote control device includes: a three-dimensional rendering unit (23) generating first and second user images from first and second three-dimensional models; a first operation determination unit (24) determining whether or not the menu image overlaps with the second user image; a second operation determination unit (24) determining coordinates of a position specified by a user, on a display screen based on an amount of the movement of the second user image in a direction perpendicular to the display screen; and an operation information outputting unit (25) outputting operation information corresponding to the menu image, when it is determined that the menu image overlaps with the second user image and when the determined coordinates are included within a display area of the menu image, and the second operation determination unit (24) calculates as the amount of the movement a difference value between a depth value of the first user image and a depth value of the second user image with reference to a depth buffer in which depth information indicative of relation between coordinates on a projection plane and a depth value is stored.
