Patent number: 9919717Abstract: Position information of a vehicle 100 and feature amounts of driving operations by a driver are acquired as triggered by occurrence of switching from an automatic driving mode to a manual driving mode, and a driving operation to be corrected in the automatic driving mode and a correction amount thereof, are determined from these feature amounts. A driving operation in the automatic driving mode is corrected using the determination result, so that the vehicle 100 is controlled in the automatic driving mode in which the corrected driving operation is included.Type: GrantFiled: April 14, 2014Date of Patent: March 20, 2018Assignee: Mitsubishi Electric CorporationInventors: Nariaki Takehara, Koji Iida, Takahisa Aoyagi, Tetsuji Haga

Patent number: 7627199Abstract: An object processing unit divides each image frame of received image data into block areas, extracts an object from each image frame, and extracts, as metadata, the features of this object for each block area. A real-time detection processing unit compares the metadata extracted for each block area with a received real-time detection query, and detects an object which satisfies the real-time detection query. A post-retrieval processing unit compares the metadata for each block area stored in a metadata storage unit with a received post-retrieval query, and retrieves an object which satisfies the post-retrieval query.Type: GrantFiled: October 5, 2006Date of Patent: December 1, 2009Assignee: Mitsubishi Electric CorporationInventors: Kazuya Sato, Tetsuji Haga

Publication number: 20090248745Abstract: A link table (28) showing a link relation between video data which are time reference data and log data which are number reference data is disposed. When the video data are deleted from a video recording ring buffer (23) or when the log data are deleted from a log recording ring buffer (26), a link data management unit (27) instructs either a number reference data recording and deleting unit (25) or a time reference data recording and deleting unit (22) to also delete the data which are the link destination of the deleted data with reference to the link table (28). Simultaneously, the link data management unit (27) deletes the link relation from the link table (28).Type: ApplicationFiled: July 22, 2008Publication date: October 1, 2009Applicant: MITSUBISHI ELECTRIC CORPORATIONInventors: Naoki Kuwahara, Tetsuji Haga, Koichi Takeuchi, Koichi Sasakawa

Publication number: 20060008118Abstract: In a conventional image monitoring system problems have been that images are very unclear and it is sometimes difficult to monitor them, because images to be monitored are displayed intact to a monitoring operator, even if monitoring-unnecessary-moving objects, such as rainfall or snow, are photographed in the monitoring images. In an image processing apparatus 1, easy-to-monitor images, in which monitoring-unnecessary-moving objects, such as rainfall or snow, have been eliminated, can be displayed to the monitoring operator, because a monitoring-unnecessary-moving-object-eliminating unit 3 processes each of pixel values of consecutive images that have been continuously photographed and stored in image storing units 2, and outputs the images in which the monitoring-unnecessary-moving objects appearing in the consecutive images have been eliminated.Type: ApplicationFiled: April 15, 2005Publication date: January 12, 2006Applicant: MITSUBISHI DENKI KABUSHIKI KAISHAInventors: Nobuyuki Matsuoka, Kenji Tanaka, Kenichi Shinbou, Tetsuji Haga
