Patent number: 11463620Abstract: An image processing apparatus includes an image corrector and an output circuit. The image corrector inputs image data. The image corrector processes the image data input by the image corrector. The image corrector arranges an input image indicated by the image data input by the image corrector on a first plane. The image corrector maps each pixel included in a part or whole of a region of the input image arranged on the first plane onto a curved surface. The image corrector maps each point mapped on the curved surface onto a second plane so as to generate new image data. The output circuit outputs the image data processed by the image corrector.Type: GrantFiled: October 12, 2018Date of Patent: October 4, 2022Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventor: Hisako Chiaki

Patent number: 10044963Abstract: An imaging apparatus includes a rolling shutter type first image sensor and second image sensor, a timing generator that controls operation timings of these two image sensors, and a controller that subjects generated image data to image processing and controls the timing generator. The first image sensor captures an image of a subject to generate first image data, and the second image sensor captures an image of the subject to generate second image data. Each of the first image data and the second image data has a duplicate region in which the subject is partly duplicated. The controller controls the timing generator in such a way that a period over which the first image sensor exposes lines within the duplicate region in the first image data coincides with a period over which the second image sensor exposes lines within the duplicate region in the second image data.Type: GrantFiled: February 10, 2017Date of Patent: August 7, 2018Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Genki Sato, Katsuji Kunisue, Hisako Chiaki

Patent number: 9232120Abstract: Disclosed is an image processor that reduces or eliminates the effects of a flash band regardless of performing a shutter operation or not. An imaging device includes a flash band detector configured to determine whether each image of the consecutive images shown by image signals output from an imager is a flash band image a part of which is affected by a flash, and a flash band compensator configured to, if a first image is determined as the flash band image, generate a third image which is supposed where the third image is fully affected by a flash by using a second image which is not determined as the flash band image, and output the third image instead of the first image.Type: GrantFiled: April 29, 2013Date of Patent: January 5, 2016Assignee: Panasonic Intellectual Property Management Co., LtdInventors: Yuki Kishida, Katsuji Kunisue, Hisako Chiaki, Ryoji Asada

Patent number: 9225958Abstract: In a video signal processor, a difference value calculation section calculates a difference value between video signals at two or more different points of view, which have been input to a video signal input section, at each predetermined timing. A compensation value calculation section holds the difference value between the video signals, which have been obtained at the predetermined timing, at each predetermined time interval. The compensation value calculation section calculates a compensation value with reduced compensation variations along a time axis using the held difference value. A video signal compensation section compensates the video signals using the obtained compensation value. Furthermore, the compensation value calculation section also calculates the compensation value with reduced compensation variations along the time axis based on information at imaging, which has been obtained by an information input section at each predetermined timing.Type: GrantFiled: November 5, 2012Date of Patent: December 29, 2015Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventor: Hisako Chiaki

Publication number: 20120120068Abstract: A display device includes an input unit, a depth direction position information processing unit, and a display processing unit. Depth direction position information is inputted to the input component. The depth direction position information is information corresponding to information about and/or the position in the depth direction of a subject. This depth direction position information is set for at least part of a two-dimensional information corresponding to a subject. The depth direction position information processing unit processes two-dimensional information. The two-dimensional information is made up of depth direction position information and either horizontal direction position information or vertical direction position information. The display processor displays an image corresponding to two-dimensional information processed by the depth direction position information processor.Type: ApplicationFiled: November 16, 2011Publication date: May 17, 2012Applicant: Panasonic CorporationInventors: Hisako Chiaki, Katsuji Kunisue
