Open the CIPO recordAbstract From the Canadian patent
A system and method accomodate several image orientation modes in a single software driver (208). The driver utilizes the same software instructions for each orientation mode in order to transfer image information to display memory (212). The driver instructions which transfer the image information to display memory utilize parameters to determine where each successive pixel of information goes in the display memory. These parameters are set at the time an orientation mode is selected, and the use of these parameters by the driver allows the same instructions to be used for each mode.

Why it's free to use
- Filed March 19, 1999 and granted February 27, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 19, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 19, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
