摘要： An image projecting system includes an image projecting device and an information processing device. The image projecting device includes: a driving control unit causing light to pass through filters of colors by time unit based on the image data, to generate light having a desired color tone and corresponding to the image data; a setting unit that sets a color of a light spot on vicinity of the projection surface; and a synchronization signal output unit that transmits, to the information processing device, a synchronization signal specifying, as a timing at which a scene including the vicinity of projection surface is to be shot, a period during which light of a color closest to the set color of the light spot is not projected. An information processing device includes a shooting control unit that causes the image capturing unit to shoot the scene in accordance with the specified timing.

摘要： A disclosed image scanning device illuminates a document with a light source, focuses light reflected from the document on an image sensor to obtain one-dimensional images of the document, and obtains a two-dimensional image of the document from the one-dimensional images. The device includes an illumination lens for dividing a light beam emitted from the light source into multiple light beams and a combining unit for combining the multiple light beams on the document. A disclosed image scanning method includes the steps of illuminating a document with a light source; focusing light reflected from the document on an image sensor to obtain one-dimensional images of the document; and obtaining a two-dimensional image of the document from the one-dimensional images. In this method, a light beam from the light source is divided into multiple light beams and the multiple light beams are combined on the document. A disclosed image forming apparatus includes the image scanning device.
