TL;DR: In this paper, a terminal device with built-in image sensor allows to use a conventional writing tool as the handwritten input means, and facilitates reading of printed document, and incorporates a scanning image sensor composed of a lens member having the optical path disposed parallel to a transparent panel, a prism member for bending the optic path at right angle to match one focal position of the lens member with the surface of the transparent panel and a light source for illuminating the surface on the transparent panels.

TL;DR: In this article, an input/display integrated information processing device has : image display circuit for displaying document and image information; image input circuit through which information of an image such as a picture, a photograph, documents drawn or written on a sheet presented by the user can be input; a visual coincidence structure for integrally combining a display screen of said image display circuits with an input screen of the image input circuits so as to establish visual coincidence of said screens as viewed from the user.

TL;DR: In this article, a character recognition machine for Japanese characters is described. But the machine is adapted to recognize Japanese characters such as kanjis and kanas, and the evaluation function which assumes its minimum value when a character extraction produces the best results is calculated by the operators simultaneously so as to minimize the value of the function.

TL;DR: In this paper, the gray levels of the pixels at the center points of the cells are extracted, and a local threshold value is found only from the extracted gray levels, and the grey levels are compared with the local threshold values, thereby binarizing the cells.

TL;DR: In this paper, the authors describe an information input apparatus that includes a touch pad, a touch information detecting unit, and a touch operation start position detecting unit which detects, using the touch information, the start position of a touch operations performed by the operator.
