Patent number: 9948828Abstract: A subject is imaged repeatedly and color images of the subject are obtained. A color histogram is generated from the color subject image obtained and a representative color is decided from the color histogram generated. A specific color range that can be considered a color identical with the representative color is decided from the color histogram and representative color. Color outside the specific color range in the color subject image is changed to gray, an image of the subject in which the non-specific colors have been changed to gray is obtained and the image is displayed. Processing such as deciding the specific color range is repeated. When an instruction to fix the specific color is issued, the specific color range is fixed.Type: GrantFiled: May 20, 2015Date of Patent: April 17, 2018Assignee: FUJIFILM CorporationInventors: Hisashi Endo, Yitong Zhang, Masahiko Sugimoto, Junya Kitagawa, Kosuke Kuribayashi

Publication number: 20110228100Abstract: Disclosed is a technique for accurately tracking a tracking target object. A disparity map image in which the disparity of each pixel of an object is shown is generated from a three-dimensional object image. A detection range is determined such that an object disposed on the front side of a pedestrian, which is a tracking target object, in the depth direction is excluded from the generated disparity map image. The pedestrian, which is a tracking target object, is detected in the determined detection range. In this way, it is possible to prevent a bike driver disposed on the front side of the pedestrian in the depth direction from being tracked.Type: ApplicationFiled: March 3, 2011Publication date: September 22, 2011Applicant: FUJIFILM CORPORATIONInventors: Koichi YAHAGI, Yitong ZHANG, Tetsu WADA, Koichi TANAKA

Patent number: 7656456Abstract: Both a specific target and the background thereof in the image of a subject are caused to take on brightnesses that are relatively appropriate. Preliminary image sensing is performed to obtain a preliminary image of the subject. The image of a face is detected from within the preliminary image of the subject and the representative luminance of the face image is calculated. If the representative luminance calculated is not appropriate, then amount of exposure is adjusted so as to make the face image slightly darker than the appropriate brightness. Regular image sensing is then carried out. If the representative luminance of the face image in the image of the subject obtained by regular image sensing is not appropriate, a tone adjustment is applied utilizing a tone curve. Thus there is obtained an image of the subject in which both the face image and its background exhibit brightnesses that are relatively appropriate.Type: GrantFiled: September 6, 2006Date of Patent: February 2, 2010Assignee: Fujifilm CorporationInventor: Yitong Zhang
