CPC G09G 3/002 (2013.01) [G09G 2320/0233 (2013.01); G09G 2320/0242 (2013.01); G09G 2354/00 (2013.01)] | 12 Claims |
1. An image processing apparatus for use with a projection system that includes a first projection-type display apparatus configured to project a first projection image so that the first projection image and a second projection image partially overlap each other on a projected surface, a second projection-type display apparatus configured to project the second projection image, and a light-shielding plate disposed between the projected surface and the first projection-type display apparatus, and configured to reduce a projected light amount on an overlapped area of the first projection image and the second projection image of the projected surface, the image processing apparatus comprising:
at least one processor and
at least a memory containing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
a correction task configured to correct an image signal that has been input to the first projection-type display apparatus,
wherein the first projection image includes:
a first area which part of the second projection image overlaps and where a luminance decreases compared to the case where the light-shielding plate is not disposed due to an influence of the light-shielding plate,
a second area that is adjacent to the first area and where a luminance increases compared to the case where the light-shielding plate is not disposed due to the influence of the light-shielding plate, and
a third area different from the first area and the second area, and
wherein when the light-shielding plate is disposed between the projected surface and the first projection-type display apparatus, the correction task corrects one of a luminance and a color of the image signal corresponding to the second area by lowering a level of the image signal corresponding to the second area in accordance with the luminance of the second area so as to reduce a difference from a corresponding one of a luminance and a color of the image signal corresponding to at least one of the first area and the third area.
