Patent number: 7237919Abstract: The invention provides a range finder capable of carrying out three-dimensional measurement stably for a long period of time. A light pattern is projected on a subject by using a light source array unit in which a plurality of light sources, such as LEDs, are arranged. Even when each LED has a small light quantity, a sufficiently large quantity of light can be projected on the subject by the entire light source array unit, and hence, the three-dimensional measurement can be stably carried out. Also, a plurality of light patterns can be generated by electrically controlling a light emitting state of each LED of the light source array unit.Type: GrantFiled: July 10, 2003Date of Patent: July 3, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kenya Uomori, Atsushi Morimura, Joji Wada, Takeo Azuma

Patent number: 7176959Abstract: In the vehicle surroundings display device of the invention, an image processor generates an image showing the situation around a vehicle. When an obstacle is detected by an obstacle detection means, the image processor determines an image missing region using the position of the border of the obstacle on the vehicle side detected by an obstacle position detection means and fills the image missing region with substitute image data. This eliminates unnaturalness of a display image the user may feel and enables the user to accurately recognize the position of a neighboring obstacle that is important in driving operation.Type: GrantFiled: September 9, 2002Date of Patent: February 13, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Satoshi Sato, Masamichi Nakagawa, Shusaku Okamoto, Atsushi Morimura, Yoshihiko Matsukawa, Kunio Nobori

Patent number: 7161616Abstract: A synthetic image viewed from a virtual point of view above a vehicle is generated, using images captured by a plurality of cameras shooting surroundings of the vehicle. In the synthetic image, an illustration image or an actual image of the vehicle is displayed in a vehicle region in which the vehicle is present. The area around the vehicle that is not shot by any of the cameras is displayed as a blind spot region.Type: GrantFiled: April 17, 2000Date of Patent: January 9, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Shusaku Okamoto, Masamichi Nakagawa, Kunio Nobori, Atsushi Morimura

Patent number: 7027616Abstract: In transmitting image data from multiple cameras to an image processing section to produce a synthesized image from respective camera images, the amount of data transmitted through a transmission path can be cut down without sacrificing the quality of the synthesized image. In accordance with a correspondence between the synthesized and camera images as described on a mapping table, a resolution specifier specifies resolutions, which should be necessary for image synthesis, for respective areas of each camera image. A compressor, provided for each of the cameras, compresses the associated camera image data according to the resolutions specified. In this manner, the image data, which has been compressed in accordance with the correspondence between the synthesized and camera images, is transmitted through the transmission path.Type: GrantFiled: July 3, 2001Date of Patent: April 11, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hirofumi Ishii, Shusaku Okamoto, Masamichi Nakagawa, Kunio Nobori, Atsushi Morimura

Patent number: 7016411Abstract: Provided are a depth image obtaining section that obtains a depth image from the same viewpoint as in the input image, a layer section that separates the input image into a foreground image and a background image as layered images using depth information of the depth image, a coding section that encodes the foreground image, a background sprite generating section that generates a background sprite image from the background image, and a sprite coding section that encodes the background sprite image. The depth image from the same viewpoint as in the input image is obtained in the depth image obtaining section, the input image is separated into a foreground image and a background image as layered images using the depth information, and based on the separated background image, a background sprite image is generated.Type: GrantFiled: June 13, 2002Date of Patent: March 21, 2006Assignee: Matsushita Electric Industrial Co.

Patent number: 6993159Abstract: A driving support system for enabling a driver to appropriately confirm environmental conditions of a moving body is provided. A plurality of imaging means for taking an image of the rear of the moving body is installed on the moving body. The plurality of imaging means have an area (OL) where their imaging areas overlap with each other, and the overlap area (OL) includes an area in the vicinity of a vanishing point (VP). Detection means obtains a stereo parallax (VD) between one imaging means and another imaging means in the overlap area (OL), and obtains a distance to an object based on the stereo parallax (VD).Type: GrantFiled: September 20, 2000Date of Patent: January 31, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hirofumi Ishii, Atsushi Morimura, Masamichi Nakagawa, Shusaku Okamoto

Patent number: 6912001Abstract: In an image processor for synthesizing images that have been taken by multiple cameras mounted on a vehicle, even if any movable part of the vehicle has changed its state, the synthesized image will have no unnatural part. A pixel synthesizer receives the images that have been captured by the cameras included in an imaging section and generates the synthesized image by reference to a mapping table. Receiving a signal indicative of the state of a movable part such as the door or hood of the vehicle, a display mode changer disables at least one of the cameras that is taking an image to be affected by any change in the state of the movable part. For that purpose, the changer rewrites mapping data stored on the mapping table and thereby eliminates the image in question from the synthesized image.Type: GrantFiled: May 25, 2001Date of Patent: June 28, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Shusaku Okamoto, Masamichi Nakagawa, Hirofumi Ishii, Kunio Nobori, Atsushi Morimura

Patent number: 6911997Abstract: To monitor both the surrounding of a vehicle and a place distant therefrom, there is mounted on the vehicle a twin-camera (23) composed of cameras (23L, 23R) forming a pair. To properly set the postures of the cameras (23L, 23R), their tilts, pans and twists around the optical axes are adjusted using, as indexes, the lengths of the portions, as captured by the cameras (23L, 23R), of the vehicle center line (BCL), the lengths of the portions, as captured by the cameras (23L, 23R), of the vehicle rear-end line (BEL), and the areas of the blind zones (S) in the capturing directions.Type: GrantFiled: October 12, 2000Date of Patent: June 28, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Shusaku Okamoto, Masamichi Nakagawa, Atsushi Morimura

Patent number: 6876392Abstract: A rangefinder according to the present invention includes light source section, camera section, distance-measuring sensor, exposure controller and shutter. The light source section projects light onto an object for 3D imaging purposes. The camera section receives the light that was emitted from the light source section and then reflected from the object. The distance-measuring sensor estimates an approximate distance to the object. Based on the approximate distance, the exposure controller controls the optical output power of the light source section and/or the open/closed states of the shutter. The rangefinder can control the intensity of the projected light even if the object is on the move. As a result, the rangefinder can obtain highly precise information about the 3D location of the object.Type: GrantFiled: December 17, 1999Date of Patent: April 5, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kenya Uomori, Takeo Azuma, Kunio Nobori, Atsushi Morimura
