There is provided a game system in which a virtual object such as a car is moved in virtual surroundings on a screen of a display. The system comprises an input device for providing from a player operating information concerning an expected motion of the object and an element for simulating the motion of the object in response to the provided information and in consideration of interaction forces between the object and the surroundings. The interaction forces are operated at least two positions of the object. The simulated results of the object Is displayed on the screen of the display.

A master strategy adjustment method includes performing first recording on a master with a predetermined strategy, performing first measurement of an evaluation value of the master of the first recording, forming a first optical disc based on the master after the first recording, performing second measurement of an evaluation value of the optical disc formed as the first optical disc, calculating a target value of the evaluation value of the master based on a difference with the first measurement evaluation value and the second measurement evaluation value, and adjusting the strategy so that the evaluation value with regard to the master matches the target value, performing recording on the master with the adjusted writing strategy, performing measurement of the evaluation value of the master, and performing determination of whether the evaluation value is within a predetermined range with the target value as a reference until an affirmative result is obtained.

An exposure apparatus includes an exposure unit selectively performing exposure on a resist layer with a first laser beam, focused by a lens system, in a pattern including pits and lands arranged in a scanning direction; a detecting unit detecting a reflection of a second laser beam applied through the lens system to the resist layer selectively exposed to the first laser beam, the second laser beam being produced by changing a focal length of the lens system such that the resist layer is prevented from responding thereto; a calculating unit calculating, from a result of the detection, a displacement between center axes of signal waveforms representing beams reflected from first and second portions of the pattern having a smallest width and a larger width, respectively; a setting unit setting the focal length of the lens system to such a value that the displacement is maximal; and a control unit controlling the exposure unit to expose the resist layer to the first laser beam focused with the focal length set by the setting unit.

In an image processing device composed such that it can display a prescribed object whilst changing the shape of the object. Furthermore, the image processing device includes a first memory for recording information for first polygons which form the object; a second memory for recording information for second polygons that form the object and are linked to the first polygons; and when the shape of the object is changed, the shapes of the second polygons are changed such that no gaps are produced between the first polygons and the second polygons. Using computer graphics in a video game it is possible to achieve a more realistic object representation, wherein joint regions move in a natural manner.

Information unique on a group basis is allowed to be efficiently added to a recording medium in which read-only contents data is recorded. Master data (cutting master) having a data structure in which data to be replaced is managed by a file system as data to be arranged in a specific folder or a specific file is produced by authoring. In manufacturing of a recording medium master disc through premastering and mastering using the master data, replacement data unique to each group is prepared, and the data to be replaced is replaced with the replacement data to perform the mastering (master disc exposure). Then, a stamper is produced from the produced master disc, and recording media is mass-produced by using the stamper. In other words, the replacement data are changed on the group basis to allow the recording media in which the replacement data (such as GP1 and GP2) unique to each group is recorded as read-only data to be manufactured, as recording media containing the same content.

A recording drive waveform adjusting method for manufacturing a master disc is provided. The method includes forming an exposed area in an inorganic resist layer for test exposure by irradiating a master disc having the inorganic resist layer with laser light of a recording power based on a recording drive waveform according to a test recording signal. The method also includes obtaining reflected-light information by irradiating the exposed area formed in the test exposure with laser light of a reproducing power, determining whether the recording drive waveform is appropriate by using the reflected-light information, and correcting the recording drive waveform if the recording drive waveform is determined to be inappropriate in the determination.
摘要:
An image processing device for realizing more realistic pictures of explosions in video game devices and the like. Objects displaying such pictures of explosions are formed of spherical polygons (R1, R2, R3, . . . ) and planar polygons (S1, S2, S3, . . . ). Pictures of explosions are realized by alternately arranging these spherical polygons and planar polygons with the lapse in time. Preferably, pictures of polygons are realized by arranging the spherical polygons in layers on the boundary of the planar polygons.

摘要:
A reproduction control method adopted by an information-processing apparatus such as a personal computer for the purpose of protecting copyrights imposes a restriction on an operation carried out by a media reproduction apparatus such as a disc drive apparatus to reproduce musical data or the like (from a recording medium mounted on the media reproduction apparatus). A command issued by the processing main member of the information-processing apparatus (including application programs and an OS) to the media reproduction apparatus such as the disc drive apparatus to read out data recorded on the recording medium in a predetermined format is monitored. If the issuance of a command to read out data recorded in a predetermined format is confirmed, a copyright protection process is carried out to protect a copyright. The copyright protection process is a process to prohibit or conditionally permit a suck-up operation (to transfer the musical data from the recording medium to the personal computer).
