  • Patent number: 7600875
    Abstract: In a projector, CPU supplies a chart generation circuit with chart display information designating display position and display size of a chart image to be projected on a screen such that it comes within viewable ranges of phase difference sensors. For focus control, CPU sets display position near center of the screen, and designates display size regardless of distance between the projector and screen. For keystone correction, CPU designates display position and display size based on relationship among angular field of view, distance, and viewable ranges of the phase difference sensors. A superimposing circuit generates a video by superimposing a video signal with a chart image signal based on the chart display information. A display device projects the video superimposed by the superimposing circuit on the screen. CPU obtains the distance to the screen based on phase difference between reflection lights obtained by a sensor unit and corrects the video.

  • Publication number: 20080036995
    Abstract: A light source 165 of a projection unit 16 AM modulates an electric current supplied to a built-in LED. The projection unit 16 projects the modulated light on a projection screen. A photoreceiver 171 receives, with a time lag, a reflected portion of the modulated light from the screen, which corresponds to a time required for the light to travel from its projection to its reception. A calculation unit 173 acquires a phase difference between the projected light and its reflection at a respective one of a plurality of points on the screen, acquires a distance from the projector to the respective one of the plurality of points on the screen, and then acquires an inclination angle of the screen. Because the distance from the projector to a respective one of the plurality of points on the screen is acquired based on the corresponding phase difference, the measurement accuracy is improved compared to the triangular distance measuring method.

  • Patent number: 7303285
    Abstract: A trapezoidal correction unit included in a projector positions a quadrangle p?q?r?s? after correction within a quadrangle pqrs before correction, by using inclination angles v and h. In this case, the trapezoidal correction unit performs correction in a manner that the quadrangle p?q?r?s? establishes symmetry with respect to a vertical line including a light axis point k which is an intersection of a light axis and a screen, and a part or the all of the bottom side of the quadrangle p?q?r?s? contacts or is positioned near a part or the all of the bottom side of the quadrangle pqrs. The trapezoidal correction unit sets the size of the quadrangle p?q?r?s? in a manner that the area of the quadrangle p?q?r?s? becomes the largest. The trapezoidal correction unit projectively transforms the quadrangle pqrs before correction represented by an input image signal into the quadrangle p?q?r?s? after correction temporally continuously.

  • Patent number: 7209225
    Abstract: Each of a horizontal chart generating unit and a vertical chart generating unit generate eight charts #0 to #7, the bright/dark sections being placed sequentially in equal distances. Each pattern of each charts #0 to #7, is shifted little by little. Each chart #0 to #7 is sequentially projected on a screen, and each of the sensor controllers obtains an average phase difference, by obtaining the sensor data obtained by the result of measuring, from the distance-measuring sensors, and obtains the angle between an ideal screen that is vertical to a center line of distance-measuring sensors and the screen, by obtaining the distance to the two distance-measuring points on the screen, based on the obtained average phase difference. A projector control unit replaces the angles that each of the sensor controllers obtains, to inclination angles ?H and ?V of the screen, and supplies the angles to a trapezoidal correction unit.

  • Patent number: 7180510
    Abstract: A field sequential color projector includes an area sensor unit having an area sensor for photographing a screen, and an optical filter for permitting only a red light having the same color as a laser beam from a laser pointer to be input to the area sensor, and a color period/timing extraction unit which extracts timings for projecting red, green, and blue images. When a projection timing for a red image arrives while an image is projected, an MPU (Micro Processor Unit) receives a light of an image projected on the screen at that time to acquire image information, and detects a position pointed by the laser beam based on the acquired image information. Even if there exists a portion having the same color as the laser beam in the projected image, a pointed position detection device accurately detects the position irradiated by a pointing light of the laser pointer.

  • Patent number: 7101126
    Abstract: End-mill machining control method and apparatus in which cutting forces tangential and normal to tool motion are detected and machining is controlled based on the detected cutting force values. A primary component Ft and motion axis components Fx, Fy of a cutting force are determined from current values of a spindle motor and motion axis motors for tool feed. A cutting-engaged angle ?en is determined from a radius R of a tool and a depth of cut I into a workpiece. A motion direction angle ? is determined from distribution motion amounts ?X, ?Y to the axes. The cutting forces Fm, Fs tangential and normal to tool motion are determined from the primary component Ft and a motion axis component Fx or Fy whichever is the largest, the cutting-engaged angle ?en, the motion direction angle ?. The accuracy of the determined cutting forces Fm, Fs is high since they are determined from the primary component Ft less affected by disturbance and the largest axis component of the cutting force.
