摘要： An image projecting system includes an image projecting device that projects image data onto a projection surface; and an information processing device connected to the image projecting device. The image projecting device includes a driving control unit, a setting unit, and a synchronization signal output unit. The information processing device includes a receiver, a shooting control unit, a light spot image detector, and an image signal transmitting unit. The receiver receives the synchronization signal from the image projecting device. The shooting control unit causes the image capturing unit to shoot the scene in accordance with the timing specified by the synchronization signal. The light spot image detector detects an image of the light spot generated by the light spot device on the projection surface or its vicinity from image data of the scene shot by the image capturing unit. The image signal transmitting unit transmits projection image data to the image projecting device.

摘要： A projection control unit controls projecting a first pattern image including first feature points and a second pattern image including second feature points. An acquisition unit acquires, from a photographing unit, a first photographed image of the first pattern image and a second photographed image of the second pattern image. An extraction unit extracts second connected components in which the second feature points in the second photographed image are connected in a predetermined direction and first connected components in which the first feature points in the first photographed image at positions corresponding to the second feature points included in the second connected components are connected. A shift amount calculation unit calculates shift amounts of the first connected components with respect to the second connected components. A first calculation unit calculates first correction information for correcting a projection target image based on the shift amounts.
