Title:
MULTI-PROJECTION SYSTEM, IMAGE PROCESSING DEVICE, AND IMAGE DISPLAY METHOD
Document Type and Number:
Japanese Patent JP2019101066
Kind Code:
A
Abstract:
To provide a multi-projection system, an image processing device, and an image display method.SOLUTION: In the multi-projection system including a plurality of projectors which are arranged so that projection images are mutually superimposed and the image processing device which generates an image to be projected by the plurality of projectors on the basis of an input image and outputs the generated image to the plurality of projectors, the image processing device includes a first image generation part which extracts a pixel having a luminance higher than a set luminance in the input image and re-arranges the extracted pixel, to correct a gradation value and generate the image and a second image generation part which corrects the gradation value of each pixel constituting the input image, to generate the image. The plurality of projectors include a first projector for projecting the image generated by the first image generation part and a second projector for reducing the brightness of light of the image generated by the second image generation part and projecting the image.SELECTED DRAWING: Figure 1
