Patent number: 11833973Abstract: A control section generates an overhead surround view composite image by combining image data acquired by plural cameras, and, combines the image data to generate a wide-range rear image, a left rear image, a right rear image, a front image and a rear image. The control section calculates angles of view of the image data that were used in generating the wide-range rear image, the left rear image, the right rear image, the front image and the rear image, respectively. The control section displays any of the wide-range rear image, the left rear image, the right rear image, the front image and the rear image in a first display region, and displays information expressing angles of view corresponding to images displayed in the first display region in a second display region in a manner of being superimposed on the overhead surround view composite image.Type: GrantFiled: June 10, 2022Date of Patent: December 5, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tomohito Higuma, Yosuke Kubota

Publication number: 20230140228Abstract: An image control system includes a rear camera, a left rear (right rear) camera, a display device, and an image control device for generating a combined image and displaying the combined image on the display device. The image control device identifies a rear target object and a left rear (right rear) target object which are closest to the vehicle in an own lane and a left lane (right lane), respectively, and changes a magnitude of the rear left-side (right-side) azimuth angle being an azimuth angle of a left (right) boundary line defining a horizontal angle of view of a rear effective range based on a combination of presence or absence of the rear target object and a level of closeness to this object and presence or absence of the left rear (right rear) target object and a level of closeness to this object.Type: ApplicationFiled: October 27, 2022Publication date: May 4, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tomohito Higuma, Jumpei Inagaki, Yosuke Kubota

Patent number: 11491915Abstract: In a first case a trimmed image generating section carries out trimming such that respective lateral direction lengths of a rear processed image and rear lateral processed images in the combined image are equal, and in a second case in which the trimmed image generating section judges that there is information that is included in the images of the first overlapping regions and is not included in the images of the second overlapping regions and information that should be included in the combined image, the trimmed image generating section carries out trimming such that the information that should be included in the combined image remains in the rear lateral processed images, and, as compared with the first case, the lateral direction length of the rear processed image in the combined image is short, and the lateral direction lengths of the rear lateral processed images in the combined image are long.Type: GrantFiled: July 21, 2021Date of Patent: November 8, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuki Takahashi, Yohei Satomi, Tomoaki Iida, Jumpei Inagaki, Tomohito Higuma

Patent number: 11390216Abstract: An electronic mirror system for a vehicle includes a rear imaging device, a left and right pair of side-rear imaging devices, a display device, an anomaly treatment device, memory, and a processor coupled to the memory. The processor causes a composite image in which a rear image and side-rear images are composited to be displayed, and detects an anomaly occurring at any one of the imaging devices. In a case in which an anomaly is detected, the processor generates a substitute image based on a captured image captured by another of the imaging devices, and causes the substitute image to be displayed. And, in a case in which the one of the imaging devices at which the anomaly is detected, is restored to the normal state by the anomaly treatment device, the processor causes the composite image to be displayed instead of the substitute image.Type: GrantFiled: June 15, 2020Date of Patent: July 19, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tomohito Higuma, Yosuke Kubota
