Publication number: 20230315058Abstract: A decision system includes an identifier and a decider. The identifier identifies, based on a captured image generated by an image capturing unit attached to a tool, a work target shot as a subject of the captured image as one of a plurality of work targets. The decider decides whether a first work target included in the plurality of work targets is a mistakable work target by comparing, by reference to at least one reference image, the first work target with a second work target also included in the work targets. If the second work target is similar to the first work target, the second work target makes the first work target the mistakable work target difficult to identify based on the captured image. The at least one reference image belongs to a plurality of reference images corresponding one to one to the plurality of work targets.Type: ApplicationFiled: March 21, 2023Publication date: October 5, 2023Inventors: Koji UEKUSA, Mutsuhiro YAMANAKA

Patent number: 7227574Abstract: An object of the present invention is to realize an image processing technique of making chromatic aberration correction excellently function and capable of efficiently correcting a chromatic aberration and to reduce storage capacity of parameters used for the chromatic aberration correction. It is constructed so that an image processing unit concurrently performs a chromatic aberration correcting process of correcting a chromatic aberration by an image capturing optical system and a color interpolating process of interpolating a dropout color component pixel by pixel on an image signal obtained from an image capturing device. On the basis of position information of a pixel to be processed obtained from the image processing unit, a control unit determines an image filter to be applied to the pixel. For example, an image filter is generated by combining a filter for chromatic aberration correction and a filter for color interpolating process.Type: GrantFiled: May 19, 2003Date of Patent: June 5, 2007Assignee: Minolta Co., Ltd.Inventor: Mutsuhiro Yamanaka

Patent number: 6812969Abstract: Provided is a digital camera in which the user can easily recognize that an image is out of focus by viewing a display image. At the time of live view display, image capturing is performed every predetermined time in an image capturing unit 3 and images for live view display are successively recorded on an image memory 209. An evaluation value computing unit 230 in an overall control unit 211 obtains an image stored in the image memory 209 and calculates an evaluation value indicative of the focus state of the image. A display image control unit 240 obtains the evaluation value, determines a focus state of the image, and controls a process to be performed by a display image processing unit 250 in accordance with the result of determination. When the image is out of focus, an image quality degrading process is performed in the display image processing unit 250 and an image of low image quality is displayed on a display 10.Type: GrantFiled: January 31, 2003Date of Patent: November 2, 2004Assignee: Minolta Co., Ltd.Inventors: Eiichi Ide, Mutsuhiro Yamanaka

Publication number: 20040051799Abstract: The present invention is directed to provide a technique of interpolating a green signal efficiently with excellent reproducibility of a high frequency pattern while suppressing an interpolation error. A process of interpolating a green signal in an image signal outputted from a CCD image pickup device 13 having a Bayer pattern is performed. A G signal interpolating unit 21 extracts green light sensing pixels of total n pieces (where n denotes an integer of four or larger) which include two nearest neighbor green light sensing pixels in an oblique direction and exist in the same direction from a green image signal obtained from the CCD image pickup device 13. The (n−1)th order function for approximating the illumination distribution of a green image received by the n green light sensing pixels is set, and the signal value of a pixel to be interpolated which is positioned in the same direction as the n pixels is derived from the (n−1)th order function.Type: ApplicationFiled: December 4, 2002Publication date: March 18, 2004Applicant: MINOLTA CO., LTD.Inventor: Mutsuhiro Yamanaka

Publication number: 20040041919Abstract: The present invention provides a digital camera capable of performing shading correction more easily. Two images PA1 and PB1 of the same subject are captured while changing the aperture. The shading states of the captured two images PA1 and PB1 are different from each other. A shading correction factor (correction information) is obtained by using the image PB1 in which shading is hardly generated, and the shading in the image PA1 is corrected on the basis of the shading correction factor. It is also possible to correct shading by using two images while changing a focal length or two images captured while changing the presence/absence of electronic flash light.Type: ApplicationFiled: December 26, 2002Publication date: March 4, 2004Inventor: Mutsuhiro Yamanaka
