Abstract: A parallax image generator establishes a plurality of projected regions around a display in predetermined intervals and generates a plurality of parallax images having different parallaxes due to being seen from respective points of view. In addition, pixels of the plurality of parallax images occupying the same position are gathered together in a pixel block, and are mapped to rendering memory corresponding to the display. A parallax image display unit displays mapped images in the rendering memory, projects the light from a pixel toward the projected region corresponding to each parallax image per pixel of the plurality of parallax images in each pixel block, and makes a 3-D image observed by positioning both eyes of an observer in adjacent projected regions and projecting the parallax images.

Abstract: A position of an observer in a stereoscopic observing region is detected by a position detecting unit. A right-eye image and a left-eye image which are seen from the detecting position are formed by an image forming unit and displayed on a display. By setting an aperture position of a projection optical system, the right-eye image is projected to the right-eye position of the observer and the left-eye image is projected to the left-eye position, thereby allowing a stereoscopic image to be observed. Further, an aperture is set so as to project the right-eye image or left-eye image to a position different from the detecting position of the observer, thereby allowing a same image to be seen to both eyes of another observer and allowing a two-dimensional image to be observed.

Abstract: An optical device for forming an image of an uneven surface, including a plane-parallel plate with a pair of parallel plane surfaces which is made of a transparent material having a refractive index larger than that of water and transparent to illuminating light. An uneven object (object having an uneven surface) is placed in close contact with one plane surface of the plane-parallel plate. A light source illuminates the uneven object through the plane-parallel plate. Among light rays scattered back into the plane-parallel plate by the uneven object and totally reflected at the other plane surface of the plane-parallel plate, only light that is totally reflected at an angle larger than the critical angle at the boundary between the plane-parallel plate and water is taken in by an image-forming device.

Abstract: When a print line is printed on a printing paper by supplying a print current to a thermal head, heating elements within the thermal head and a transfer ribbon are easily adhered together due to melted ink on surface of the transfer ribbon. Due to such adhering between the heating elements and the transfer ribbon, a white line is easily formed on a printing paper. In order to prevent such white line from being formed, the heating elements must be prevented from being cooled down after printing each print line. More specifically, in a period between a first time when each print line is completely printed and a second time when a printing paper is to be transported forward to a next print line, the heating elements are heated by relatively small heating value which is sufficient to melt a adhering portion formed between the heating elements and the transfer ribbon but which is insufficient to perform the printing.

Abstract: A method of detection of a wiring pattern using triangulation to detect a height thereof, comprising the steps of scanning a light beam from a light source, illuminating the wiring pattern to be detected by the scanned light beam, focusing the light reflected from the wiring pattern or a substrate, applying the focused light beam to a beam-splitter, and converting a wiring pattern configuration to a corresponding electric signal. Further, by blurring the focused light entering the beam-splitter, an expansion of a measurable height domain of the wiring pattern is possible. Furthermore, by applying a correction factor in response to the height of the substrate, the detected output of the wiring pattern height for a curved substrate can be sliced with a more appropriate slice level. Further, the beam-splitter comprises a reflection portion, a half reflection and half transmission portion, and a transmission portion.

Abstract: The image data including a grid pattern to be printed by a thermal printer line by line is stored for three lines of dots in a plural line buffer, and the image data is scanned by a window frame of an inverted T-shape which covers the three lines. When a dot arrangement extracted by the window frame including an object dot and its surrounding dots coincides with a predetermined window frame pattern defined in an intermediate table, an address representing the dot arrangement is convertred into an intermediate code by the intermediate table. The intermediate code indicates the amount of heating energy to be supplied to a heating element corresponding to the object dot in order to preheat when the area of the object dot is a non-printing area, or to heat additionally when this area is a printing area, thereby to prevent a thin or broken portion from appearing in the printed pattern line.

Abstract: A thermal transfer type printer prints a desirable dot pattern on a printing paper by heating heating cells within a thermal head which is pressed against the printing paper via a transfer ribbon, the surface of which is painted by thermal melting ink. A memory stores two kinds of current-on time data, each of which represent specific current-on time characteristics designating a relation between the current-on time and a surrounding temperature of the thermal head. This surrounding temperature is detected by a thermistor mounted on the thermal head. One of two current-on time characteristics can be arbitrarily selected, and desirable current-on time is read from the selected current-on time characteristics based on the detected surrounding temperature. Some heating cells are selected in accordance with the desirable dot pattern and the selected heating cells are heated for the desirable current-on time.

Abstract: A method of thermally printing a multicolor image on a print paper is disclosed. With this method, a lengthy multicolor image can be printed on a paper over a plurality of pages of a length determined by a length of each ink zone of an ink ribbon. First, the ink ribbon is set over a platen roller with the paper being interposed therebetween, the ink ribbon having plural groups of ink zones, the ink zones of each group carrying a plurality of heat-dissolving inks of different colors, respectively. One of the ink zones is positioned at a printing position where a thermal head contacts with the platen roller through the ink ribbon and paper. The thermal head is then activated in accordance with image data stored in a memory, and the ink ribbon and paper are advanced to effect transfer of ink so that one of color component images of the image is printed on the paper. The ink ribbon and paper are then advanced by a predetermined distance to separate the paper from the ink ribbon.
