Abstract

A projection system includes a light source, an imaging unit, a control unit, a storage unit, and a projecting unit. The light source applies light beam having a predetermined wavelength. The imaging unit captures a subject to which the light beam is applied. The control unit generates image data for projection based on the captured image. The storage unit stores plural pieces of figure information each representing image data of an object having a predetermined figure. The projecting unit projects a projection image onto the subject. The control unit selects figure information from the stored figure information, based on a degree of similarity with an image of a captured region responding to the light beam. The control unit generates the image data for projection such that an image including a figure indicated by the selected figure information is projected onto the region responding to the light beam.

Claims8

Dependent claims

A projection system comprising:

a light source for applying a light beam having a predetermined wavelength;
an imaging unit for capturing a subject to which the light beam having the predetermined wavelength is applied;
a control unit for generating image data for projection based on the image captured by the imaging unit;
a storage unit for storing plural pieces of figure information each representing image data of an object having a predetermined figure;
and
a projecting unit for projecting, onto the subject, a projection image based on the image data for projection, wherein
the control unit
selects a piece of figure information from the plural pieces of figure information stored in the storage unit, based on a degree of similarity with an image of a region responding to the light beam having the predetermined wavelength captured by the imaging unit, and
generates the image data for projection such that an image including a figure indicated by the selected piece of figure information is projected onto the region responding to the light beam having the predetermined wavelength.
