Patent number: 10639013Abstract: An ultrasound diagnostic apparatus performs transmission and reception of ultrasonic waves for forming focal points used to set sound velocities at predetermined timing such that sound velocities having been set for all of respective segment regions established by diving a subject are all reset every predetermined number of frames. Owing to this configuration, it becomes possible for the ultrasound diagnostic apparatus to suitably reset sound velocities of ultrasonic waves in the subject and also reduce the amount of calculation for resetting sound velocities.Type: GrantFiled: July 25, 2017Date of Patent: May 5, 2020Assignee: FUJIFILM CorporationInventors: Yasunori Ohta, Tsuyoshi Tanabe, Noriaki Ida, Shin Nakata, Hiroshi Yamaguchi

Patent number: 6822757Abstract: A first relationship of correspondence from RGB data to colorimetric values is univalently determined by using an sRGB space, i.e., a standard space which is colorimetrically defined, and a second relationship of correspondence from CMYK data to the colorimetric values is determined. After K data among the CMYK data is constrained under a predetermined condition corresponding to saturation and lightness, an inverse relationship of correspondence from the colorimetric values to CMYK data is univalently determined. Further, a forward relationship of correspondence from the RGB data to the CMYK data is determined from the first relationship of correspondence and the inverse relationship of correspondence.Type: GrantFiled: June 18, 1999Date of Patent: November 23, 2004Assignee: Fuji Photo Film Co., Ltd.Inventors: Yoshinori Usami, Shin Nakata
