Publication number: 20070139435Abstract: The present invention has as an object to propose a texture mapping method which enables smooth shading, and is also appropriate for conserving memory resources. In order to achieve this object, in this invention, data regions with different color tones are set so as to form density gradients in the U coordinate direction and in the V coordinate direction of the texture data. If the brightness of the surface of the object to which texture mapping is performed is I, then among the coordinates to be read to access texture fdata, the U coordinate is calculated as U=a*I+b, and the V coordinate is determined from V=d. The value of the dynamic variable d can be set appropriately according to the application. Because the texture data is such that color tone density gradients are formed in two mutually orthogonal directions, smooth shading is possible, and a plurality of texture memory areas can be consolidated to conserve memory usage.Type: ApplicationFiled: February 16, 2007Publication date: June 21, 2007Inventors: Yuichi Higuchi, Naohiro Warama

Patent number: 6977739Abstract: When an engine detects changes in condition such as a power-OFF operation, an out-of-paper state, or the like, it sends a condition change signal indicating that the condition has changed to an engine control unit. The engine control unit inquires of the engine as to the contents of the changes in condition using a command signal so as to examine the cause of the changes in condition. When a power supply is scheduled to be turned off, a message indicating it is supplied to a host computer that uses the printer, or job conditions are saved, and the host apparatus is informed of the saved job conditions after the power supply is turned on again. In the case of the out-of-paper state as well, a message indicating it is supplied to the host computer that uses the printer. The items to be informed can be selected from the host computer.Type: GrantFiled: August 12, 1997Date of Patent: December 20, 2005Assignee: Canon Kabushiki KaishaInventors: Yuichi Higuchi, Takashi Kotani

Patent number: 6963424Abstract: A calibration for the printing apparatus is performed under relatively easy management by a host computer and then the printing apparatus always can perform printing in a condition where an appropriate calibration is made for the printing apparatus. More specifically, the printer holds calibration data downloaded from the host computer and executes a density control (S1001) which generates calibration data at a predetermined timing independently in the printer. Then, the printer checks whether a difference between a print density value represented by the calibration data generated in the printer and a print density value represented by the calibration data held is greater than a predetermined threshold value (S1003). When the difference is greater than the predetermined value, the printer notifies an error (S1004) and sets a correction table based on the calibration data generated by the printer (S1006).Type: GrantFiled: June 29, 2000Date of Patent: November 8, 2005Assignee: Canon Kabushiki KaishaInventor: Yuichi Higuchi
