    摘要: An image projection device includes: a drive controller that causes generation of light of a specified color tone by a combination of light to be transmitted by a liquid crystal panel to project image data onto a projection plane; an image capturing controller that receives a synchronization signal that specifies a period in which the liquid crystal panel does not transmit light from the drive controller and causes capturing of an image of the projection plane according to the period that is specified by the synchronization signal; an illuminated image detector that detects, from the captured image of the image data, an illuminated image that is illuminated by an illuminating device on the projection plane; and an illuminated image generator that generates projection image data obtained by combining given image data in a position in which the illuminated image is detected.

    摘要: An image processing device extracts, for a target area that has sites having different flexibilities and where markers corresponding to the respective flexibilities are put on the sites, marking positions where the markers are put according to each type of the markers from each of a first image to be projected and being an image of the target area captured in advance and a second image being an image of the target area captured before projection of the first image; executes, based on the extracted marking positions according to each type of the markers, image processing to align the marking positions of the markers contained in the first image with the marking positions of the markers contained in the second image by a processing method corresponding to the types of the markers; and generates, based on the processed first image, a projection image to be projected onto the target area.
