  • Patent number: 11507766
    Abstract: A method for processing an encoded pattern, a storage medium, and an electronic device are disclosed in this application. An electronic device acquires a first encoded pattern to be recognized, the first encoded pattern being a pattern obtained after predefined information is encoded therein. The electronic device increases resolution of the first encoded pattern through a target model to obtain a second encoded pattern, the target model being obtained through training by using a predetermined third encoded pattern as an input and a predetermined fourth encoded pattern as an output, the third encoded pattern being obtained by decreasing resolution of the fourth encoded pattern, the third and the first encoded patterns being encoded in the same manner. Finally, the electronic device decodes the second encoded pattern using a code recognition module to obtain the predefined information. This application resolves the technical problem that an encoded pattern cannot be accurately recognized.

  • Patent number: 8459801
    Abstract: An object of the present invention is to display a highly reproducible three-dimensional image in response to changes in the viewer's position and to easily realize the miniaturization of the system. The three-dimensional image projector includes a projection image forming disc in which a hologram recording medium is formed along a disc-shaped glass substrate, and which projects image light having directivity by causing the image light to fall incident on the hologram recording medium, and a rotational drive unit for rotationally driving the projection image forming disc along a surface of the glass substrate with the center point on the surface as a rotation center. The projection image forming disc is preliminarily recorded with a hologram by causing two laser beams as reference light and object light to simultaneously fall incident on the hologram recording medium.

  • 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: 4139287
    Abstract: A slide body of a rigid transparent material is sized to be received within a slide transparency projector. The slide body includes a bubble level indicator having a narrow arcuate chamber which is filled with a liquid to create a bubble of air trapped within a band of fluid. The bubble is displaceable within the arcuate chamber and remains at the highest point therein. When the slide is level, the bubble rests at the mid-point of the band. The slide body is also provided with a pattern of concentric rectangles and a pattern of markings to indicate the extent of deviation of the bubble from its position at the mid-point of the band. The arcuate band, bubble and pattern of markings are projected onto the screen by a projector to permit a projectionist to readily ascertain whether or not the projector is in focus and is level. The projector can then be focused and leveled by adjusting the focusing and leveling system of the projector.
