Abstract:
An image detection device comprising a projector which projects a reference light on an object;an image sensor which senses an image of the object and converts said image into electrical signals; anda controller for controlling said projector and said image sensor, wherein when said controller prevents said projector from projecting the reference light, said image sensor captures the image of the object for obtaining a two-dimensional image information of the object, and when said controller instructs said projector to project the reference light, said image sensor captures the image of the object for obtaining a three dimensional image information of the object;wherein said image sensor comprises:an aperture that restricts a passage of entering light into said image sensor; andan aperture controller for independently setting a first aperture value for the aperture when obtaining a two-dimensional image information and setting a second aperture value for the aperture when obtaining a three-dimensional image information.
