Patent number: 7929761Abstract: Software of a simple configuration checks whether an original image to be corrected is an image picture, and an image correction process based upon a formed histogram of the original image is not performed for an image different from the image picture. An image processing condition is set in accordance with the formed histogram to perform the image correction process for the original image. An image processing method judges from a shape of the formed histogram whether the original image is an image picture, and does not perform not perform the image correction process for the original image if it is judged that the original image is not an image picture.Type: GrantFiled: August 26, 2009Date of Patent: April 19, 2011Assignee: Canon Kabushiki KaishaInventors: Manabu Yamazoe, Nobuo Ogura, Akihiko Uekusa, Kentaro Yano, Tetsuya Suwa

Patent number: 7321450Abstract: According to an image processing method for performing color processing in accordance with a plurality of image objects, image data representing the plurality of image objects is input. The relationship between the plurality of image objects is analyzed. The plurality of image objects are grouped based on the result of analysis. The same color processing condition is set for the plurality of image objects belonging to the same group. Thus, the same color processing condition is set for the plurality of image objects divided from a single original image, thereby obtaining a high-quality output image.Type: GrantFiled: July 20, 2004Date of Patent: January 22, 2008Assignee: Canon Kabushiki KaishaInventors: Akihiko Uekusa, Nobuo Ogura, Manabu Yamazoe

Patent number: 6954288Abstract: An image-processing method for performing color matching using a source profile and an output profile, includes a step of correcting input image data, a step of calculating a feature quantity of an input image based on the corrected image data, a step of performing an image correction process on the input image data in accordance with a processing condition responsive to the feature quantity, and a step of performing a color matching process on the corrected input image data. The image-processing method is thus performed with the color matching process result taken into account.Type: GrantFiled: December 22, 2000Date of Patent: October 11, 2005Assignee: Canon Kabushiki KaishaInventors: Akihiko Uekusa, Manabu Yamazoe

Patent number: 5122953Abstract: A word processor capable of creating a formula during a document editing process by automatically setting a range of a formula in a document being edited with an instrument of a formula process start command and allowing a switching operation between the document editing process and the formula creating process to be easily made. This allows the formula to be edited on a block basis, thereby facilitating the editing operation such as modification, addition, or deletion of the formula in accordance with any editing of character trains or symbols inside and outside the formula in a well-balanced manner. The word processor is also capable of automatically defining the position, size, and form of a symbol in accordance with the length and form of an object to which the symbol is to be added, so that the position, size, and form of the symbol can be automatically accommodated in accordance with any change in the object to which the symbol is to be added without bothering an operator.Type: GrantFiled: August 30, 1989Date of Patent: June 16, 1992Assignee: Canon Kabushiki KaishaInventors: Akihiko Uekusa, Shinko Sugiyama, Masaki Hamada, Akifumi Shirasaka, Tetsuaki Yaguchi
