Patent number: 8140254Abstract: In a road map data generation apparatus, existing primary road map data is subjected to a deletion process according to a deletion rule to delete a portion of the data. Thus, reduced road map data is generated for a storage medium such as a memory card having a data volume smaller than the primary road map data. A navigation apparatus using the reduced road map data stored in the memory card records a restoration rule pairing with the deletion rule. Based on the restoration rule, the reduced road map data can be restored to the primary road map data. Thus, the deletion rule can decrease the data volume of the primary data to thereby generate the reduced data, whereas the restoration rule can restore the reduced data to the primary data in the navigation apparatus. This helps prevent worsening of the quality of the road map data and lowering of the user's satisfaction.Type: GrantFiled: June 24, 2008Date of Patent: March 20, 2012Assignee: Denso CorporationInventors: Shigehiro Mutoh, Toshio Nomura

Publication number: 20110002383Abstract: An image quality/rate control portion 106 confirms whether a predictive code amount Ci is a target code amount Rt or less. When the predictive code amount Ci is the target code amount Rt or less, the predictive code amount Ci is output to a base layer coding portion 101. Then, a switch 108 is turned off. When the predictive code amount Ci exceeds the target code amount Rt, the target code amount Rt is output to the base layer coding portion 101. Then, the switch 108 is turned on and (predictive code amount Ci?target code amount Rt) is output to an enhancement layer coding portion 103. A buffer 104 stores coded data of the base layer coding portion 101 and the enhancement layer coding portion 103. In this manner, while performing fixed bit rate coding using a single transmission path, image quality of a moving image is made constant so as to prevent deterioration of image quality.Type: ApplicationFiled: January 26, 2009Publication date: January 6, 2011Inventors: Toshiyuki Yoshida, Tomoko Aono, Norio Itoh, Toshio Nomura, Tomohiro Ikai, Takeshi Tsukuba

Patent number: 7859529Abstract: A controller 103, based on the positional information of the display image, selects whether the 3-dimensional image data decoded by a decoder 102 is displayed stereoscopically (in 3-dimensional display mode) or planarly (in 2-dimensional display mode) and gives notice of the selected display mode to a display portion 104. Specifically, the input positional information=display address is monitored, and if no temporal change occurs, namely if the displayed position of the image data does not change, 3-dimensional display mode is selected as the display mode. On the other hand, if there is a temporal change, namely if the displayed position of the image data varies by scrolling, 2-dimensional display mode is selected as the display mode. Thus, an image data display apparatus which can efficiently display image data on a display when display of 3-dimensional image data is scrolled is provided.Type: GrantFiled: August 11, 2005Date of Patent: December 28, 2010Assignee: Sharp Kabushiki KaishaInventors: Yasuaki Tokumo, Toshio Nomura
