1. An image processing apparatus, comprising:
- a real-space image acquisition unit operable to acquire a real space image;
a virtual space image acquisition unit configured to acquire a first virtual space image including a chroma key region defined by a pixel group having a chroma key color which is set in advance;
a composition unit operable to execute chroma key composition of the first virtual space image on the real space image based on said chroma key color included in the first virtual space image; and
an output unit adapted to output, to a display device, a composite image generated by the chroma key composition processing of said composition unit, the image processing apparatus characterized by further comprising;
a determination unit configured to determine whether or not an error part exists at a boundary between the chroma key region and a non-chroma key region, based on a second virtual space image acquired by said virtual space image acquisition unit; and
a correction unit operable to correct the error part, if said determination unit determines that the error part exists, based on a chroma key region of the second virtual space image.

Abstract
A left-eye color discrimination unit (1101) and right-eye color discrimination unit (1102) generate mask images from virtual space images. If an error part exists at the boundary between a chroma key region and non-chroma key region in the mask image, each of a left-eye mask correction unit (1108) and right-eye mask correction unit (1110) corrects the error part using another mask image generated based on the other virtual space image in addition to the virtual space image.

12. An image processing method, comprising:
-
acquiring a real space image; acquiring a first virtual space image including a chroma key region defined by a pixel group having a chroma key color which is set in advance; executing chroma key composition of the first virtual space image on the real space image based on the chroma key color included in the first virtual space image; and outputting a composite image generated by the chroma key composition processing in the composition step to a display device, said method characterized by further comprising; determining based on a second virtual space image, acquired in the virtual space image acquisition step whether or not an error part exists at a boundary between the chroma key region and a non-chroma key region; and correcting, if it is determined in the determination step that the error part exists, the error part based on a chroma key region of the second virtual space image.

13. A machine-readable storage device storing a computer program which when loaded into a computer and executed performs an image processing method, the method comprising:
-
acquiring a real space image; acquiring a first virtual space image including a chroma key region defined by a pixel group having a chroma key color which is set in advance; executing chroma key composition of the first virtual space image on the real space image based on the chroma key color included in the first virtual space image; and outputting a composite image generated by the chroma key composition processing in the composition step to a display device, said method characterized by further comprising; determining based on a second virtual space image, acquired in the virtual space image acquisition step whether or not an error part exists at a boundary between the chroma key region and a non-chroma key region; and correcting, if it is determined in the determination step that the error part exists, the error part based on a chroma key region of the second virtual space image.
