Title:
IMAGE OUTPUT APPARATUS, PROJECTION APPARATUS, CONTROL METHOD THEREOF, SYSTEM, AND PROGRAM
Document Type and Number:
Japanese Patent JP2019125830
Kind Code:
A
Abstract:
To achieve both resolution enhancement by pixel shift and jaggy reduction in pixel shift control by multi-projection.SOLUTION: In a system including an image output apparatus and a plurality of projection apparatus, the image output apparatus includes generation means for generating a projection image projected by each of the projection apparatuses and in which the pixel positions of the projection images are shifted by a predetermined shift amount, shift amount calculation means for calculating the shift amount between the projection images, determining means for determining pixel information for interpolating a difference between the predetermined shift amount and the shift amount when the generation means generates the projection image, and output means for outputting the projection image generated on the basis of the pixel information by the generation means to each of the projection apparatuses, and the plurality of projection apparatuses include acquisition means for acquiring the projection image from the image output apparatus, and projection means for projecting the projection image acquired by the acquisition means.SELECTED DRAWING: Figure 3
