Title: Area decision device
Inventor: OSUGA BUNICHI
IPC: H04N1/40
Filed: 1993-06-02
Abstract: PURPOSE:To provide the area decision device which generates no void even if there are boldfaced characters in a document and has a small possibility of making misdecision even if a text area and a confusing image area are present. CONSTITUTION:A 1st decision circuit 21 decides whether a desired pixel is included in the image area or the text area (character area) on the basis of the desired pixel and density differences from its peripheral pixels. Further, this 1st decision circuit 21 decides that the desired pixel is in the text area irrelevantly to the density differences on condition that the density of the desired pixel is less than a specific lower-limit value or larger than a specific upper-limit value. A 2nd decision circuit 23 searches an area nearby the desired pixel that the 1st decision circuit decides as a pixel in the text area and cancels the decision on the text area unless more than a specific number of pixels are present in the text area to decide the desired pixel is in the image area.

Title: Distance measuring apparatus
Inventor: OISHI TADAHISA
IPC: G01S7/48
Filed: 1992-04-24
Abstract: PURPOSE:To reduce the measuring error of the title apparatus by a method wherein a single-mode optical-fiber coupling-type light-waveguide modulator is used as a means to demodulate a beam of returned light from a reflector and a lens system which reduces the beam diameter of the beam of returned light and which changes the beam into a beam of parallel light is installed. CONSTITUTION:A single-mode optical-fiber coupling-type light-waveguide electro-optical intensity modulator 9 is used as a means to demodulate a beam of returned light. The modulator 9 is provided with a single-mode light waveguide 9A. When a beam of light which has been modulated is radiated toward a reflector, the beam diameter of the beam is expanded by means of a beam expander 6 and the beam is changed into a beam of parallel light so that the beam of returned light from the reflector is advanced and passed to a direction opposite to that of its radiation; it reduces the beam diameter of the beam of returned light and changes it into a beam of parallel light. Since the expander 6 is installed between a condensing lens 8 and the reflector, a loss in the quantity of light is caused only in the peripheral part of the beam of returned light even when a dislocation delta is caused. The intensity of light is low in the peripheral part of the beam of returned light, and a fluctuation in the loss amount of the quantity of light due to a fluctuation in the air hardly affects a beam of detection light.
