Abstract:
PROBLEM TO BE SOLVED: To provide a display method using a computer capable of dealing with a universal and real time moving image. SOLUTION: The display method includes: a process for reading vertex coordinate values of a polygon character (17) for front/rear discrimination for each frame; a process for calculating a Z value of the polygon character (17) for front/rear discrimination; a process for obtaining a three-dimensional polygon character (21); a process for comparing the Z value of the polygon character (17) for front/rear discrimination with the Z value of the three-dimensional polygon character (21) in pixel units; a process for performing hidden surface removal; and a process for obtaining a combined screen.

Abstract:
PROBLEM TO BE SOLVED: To provide an image compression device for an image format incapable of containing alpha data that compresses an image with alpha data attached. SOLUTION: An image processing apparatus includes an image data input part 1, a first conversion part 3 for dividing a data block into a color data block and a transparency data block and converting the color data block into a macro block of color data, a second conversion part 5 for converting the transparency data block as a color data block into a macro block of transparency data, a coding part 7 for combining the macro block of color data and the macro block of transparency data into a set of macro blocks and coding the set of macro blocks, and an output part 9 for outputting the coded data.

Abstract:
PROBLEM TO BE SOLVED: To provide a triangular surveying apparatus using large aperture concave mirror. SOLUTION: The present invention relates to the triangular surveying apparatus using large aperture concave mirror, and moreover gives a detailed account of the triangular surveying apparatus using a large aperture concave mirror where concentration ratio of the light intensity incident into an object is enhanced by the use of the large aperture concave mirror to obtain a more exact image resulted in high precision. The apparatus is characterized by including an arbitrary illumination lamp emitting line light, a large aperture concave mirror for reflecting line light emitted from the arbitrary illumination lamp toward the surface of the object, and a camera for receiving reflected light from the object. The apparatus broadens further the measuring domain of a three-dimensional bump obtained by forming converging light with the large aperture concave mirror, and also has an effect reducing a shape error.

Abstract:
A motion producing device comprising an output member with a contact surface and a reference member. An actuator member is attached to the reference member, the actuator member having a traction surface and comprising actuator zones, each actuator zone being energizable to move a corresponding portion of the traction surface to change a contact state of the traction surface with the contact surface depending on an energized state of the actuator zone. An energy source is operatively coupled to the actuator zones for sequentially changing the energized state of the actuator zones. The actuator member provides a torque transmission path between the reference member and the output member.
