Abstract: An image input device comprises a mirror body which is designed in a polygonal prism form and has side peripheral surfaces each formed of a mirror face, image pickup light from a subject being reflected from the mirror face, and a linear sensor for talking the image pickup light reflected from each mirror face of the mirror body to perform photoelectric conversion on the image pickup light. The mirror body is arranged so that the length direction thereof is substantially parallel to the length direction of the linear sensor, and disposed so as to be rotatable around a shaft at the center of the bottom surface which are substantially perpendicular to the length direction of the mirror body.

Abstract: A computer obtains a change amount of an image of a manuscript. If the change amount of the image of the manuscript is equal to or larger than a predetermined threshold, the computer determines that the image does not have movement, such as in a case where the manuscript is replaced, and switches the resolution of the image, which is possible to shorten the processing time, to low resolution. In a case where the manuscript is placed on a base, if the change amount of the image of the manuscript is less than the predetermined threshold, and the computer determines that the image does not have movement, the computer switches the resolution of the image to high resolution.

Abstract: An enhanced reading device that which secures written material in a fixed location and moves a video camera across the written text or images for the purpose of automatically registering the video camera at the beginning of each new line. The device uses a manually operated transmission to move a camera across a line at a speed controlled by the user. The video camera is also stepped to the next line under control of the user. Optional embodiments permit the transmission to be powered and control by push buttons for automatic registration at the beginning of new lines. The device also has a document tray assembly to control vertical movement of the document in relation to the video camera under control of the user. The document tray assembly can also be optionally powered rather than manually operated.

Abstract: The present invention provides a digital camera capturing technique for documents. In one embodiment, a method for a digital camera capturing technique includes determining an orientation of an object (e.g., a document) relative to an optical axis of the digital camera, and determining a distance of the object from the digital camera. The method also includes determining a planarity of the object (e.g., a curl of the document). The method further includes projecting a pattern on the object, and detecting the projected pattern, which is then processed to determine the orientation of the object relative to the optical axis of the digital camera, the distance of the object from the digital camera, and the planarity of the object.
