  • Publication number: 20080088626
    Abstract: A 3D image data compression system, a method a program and a recording medium storing the program are provided for effectively compressing a data amount and obtaining a decompressed 3D image with little distortion. A recording medium also is provided for storing the compressed 3D image data. The system generates, a cut path based on a texture distribution of the surface of the 3D image so as to reduce the distortion of the 3D image reproduced from the compressed data. Geometric information and optical information of the 3D image data are correlated with points within a 2D planar figure based on the texture distribution of the surface of the 3D image so as to reduce the distortion of the 3D image reproduced from the compressed data.

  • Patent number: 7008052
    Abstract: An ink jet printer includes ink jet heads for recording an image on a recording medium, an ink bottle for holding ink, an ink supply path connecting the ink bottle to each ink jet head, and an electromagnetic valve provided on the path. In the printer, the bottle, the valve and the heads are arranged downward in this order in the vertical direction, the path constantly exists upwards in the vertical direction in such a manner that air entered into the path moves up above the valve due to a difference in the specific gravity between the air and the ink, the path is provided with a branching portion provided between the valve and the heads, and a sub ink tank is provided at an end of the branching portion so as to be positioned lower than the heads in the vertical direction.

  • Publication number: 20050219523
    Abstract: A foreign matter detecting system which can acquire a clear image and detect a foreign matter with high accuracy based on the acquired image regardless of whether a subject is located far or near from an image capturing device in spite of a depth variation or a level difference. An image capturing unit having an externally controllable focus position is disposed above or below a liquid surface, and a ray of light from an LED is illuminated toward the liquid surface from above or the side at least at a focus position of the image capturing unit so that a foreign matter on the liquid surface causes mirror reflection. The focus position of the image capturing unit is changed over the range from the top of a container containing a liquid to the bottom thereof. At each focus position, an input image from the image capturing unit is taken into an image input unit of an image processing section.

  • Patent number: 4370051
    Abstract: A actuating apparatus for an electrophotographic device having a photosensitive drum mountable through an opening of a sidewall of the device, a detachable lid to close the opening, and a separator pawl adapted to separate a recording paper from tight contact with the drum. The actuating apparatus includes an actuator secured to the separator pawl so as to move the separator pawl between an operating position substantially in contact with the drum and a retarded position away from the drum, a bias device normally urging the separator pawl to the retarded position, and a stopper integrally secured to the lid in such a manner that when the lid is attached in position to the sidewall, the stopper automatically engages the actuator so as to keep the separator pawl at the operating position, whereas when the lid is detached from the sidewall, the stopper disengages from the actuator so as to automatically move the separator pawl to the retarded position for clearing the path of the drum.
