FIELD: physics.
SUBSTANCE: image construction device, designed to superimpose a superposition image onto the colour region of colour background projection of a base image and to output the superposition image as the constructed image. The image construction device includes a storage module designed to store the position and size of the region to which the superposition image is mapped. The device also includes a module for changing the position and size of the image, which is designed to change the position and size of the superposition image according to information obtained from the storage module. Furthermore, the device includes a module for making a decision on the presence or absence of said base image.
EFFECT: providing continuous output of a superposition image even without a base image signal.
