Patent number: 7791604Abstract: A graphics drawing apparatus able to reduce the amount of data transferred, able to realize a lower power consumption, and consequently able to achieve an improvement of performance of the system as a whole, provided with address generator for automatically generating addresses of drawing parameter registers required for the drawing in a defined sequence of drawing parameters according to address data and a specified drawing type; a register address selector for selecting either of the address data for specifying the register addresses of the address generator transferred through a general purpose bus or the address data for specifying the register address of the address generator by a former engine and inputting the same to the address generator; and a drawing data selector for selecting either of the drawing parameter data transferred through the general purpose bus or the drawing parameter data from the former engine and inputting the same to the drawing engine, and a method of the same.Type: GrantFiled: June 30, 2005Date of Patent: September 7, 2010Assignee: Sony CorporationInventors: Hideaki Tomikawa, Junichi Fujita

Patent number: 7151862Abstract: Texture data filtered according to each of different reduction ratio are stored in a texture buffer. A texture mapping apparatus (an lod calculating apparatus) calculates an lod (Level Of Detail) which represents a reduction ratio of each pixel of a polygon. The calculation does not include a divisional calculation. In other words, the lod calculating apparatus does not need many multipliers, as compared with a case in which an operation including a divisional calculation, thereby enabling the down-sizing of the lod calculating apparatus.Type: GrantFiled: November 19, 2002Date of Patent: December 19, 2006Assignee: Sony CorporationInventors: Tanio Nagasaki, Hideaki Tomikawa, Seigo Iwasaki, Tetsuo Motomura, Masahiro Igarashi

Patent number: 6409642Abstract: An assembling device for supplying and assembling a part on an object has a table and a first moving portion disposed above the table, where the first moving portion includes a guide and a movable body. The guide extends in a first direction parallel to a surface of the table out of a range in which the table is positioned. The movable body is movable to a position out of the range in which the table is positioned. The assembling device also has a second moving portion disposed on the table and movable in a second direction transverse to the first direction, the object being mounted on the second moving portion.Type: GrantFiled: May 18, 1999Date of Patent: June 25, 2002Assignee: Sony CorporationInventors: Morio Tominaga, Katsuya Arai, Shoichi Hayashi, Kenichi Kato, Tsuyoshi Inoue, Hiroyuki Suzuki, Tetsuo Higewake, Hideaki Tomikawa, Takeshi Tokita, Norifumi Otsuka, Hiroshi Teranishi
