Patent number: 9041821Abstract: An image obtaining unit continuously obtains plural images each showing a moving subject and motionless subject. Dark current noise is removed from the plural images. Image portions of the moving subject are extracted from the plural images with noise removed, which image portions occupy different positions in the plural images, respectively. Image portions of the motionless subject are extracted from the plural images with noised removed, which image portions occupy the fixed positions in the plural images, respectively. The extracted image portions of the moving subject are moved in the plural images with noise removed based on the corresponding positions in the respective images. The moved image portions of the moving subject are combined with the mage portions of the motionless subject held at the fixed positions in the plural images with noise removed, whereby a shooting image is composed.Type: GrantFiled: March 8, 2013Date of Patent: May 26, 2015Assignee: CASIO COMPUTER CO., LTD.Inventors: Motoyuki Kashiwagi, Kosuke Matsumoto

Patent number: 8411181Abstract: The digital still camera 1 has CCD 33 with an electronic shutter for controlling an exposure amount, and a timing generator 34 and a vertical/horizontal driver 35 for driving CCD 33. Under control of a controlling unit 42, the timing generator 34 and a vertical/horizontal driver 35 generate an electronic shutter pulse signal once every time plural periods have come each for reading charge of one line from CCD 33. Power consumption can be reduced in controlling exposure using the electronic shutter.Type: GrantFiled: September 13, 2010Date of Patent: April 2, 2013Assignee: Casio Computer Co., Ltd.Inventors: Motoyuki Kashiwagi, Takashi Itoh, Hiroyuki Nakata

Patent number: 8330842Abstract: An amplifier control device controls an amplifier which amplifies a first signal supplied from an image-pickup element, and supplies a second signal acquired by amplification of the first signal to a signal processing unit which is a following stage. The amplifier control device comprises a control unit which changes a current supplied to the amplifier depending on whether or not the first signal supplied to the amplifier is used for image data.Type: GrantFiled: May 5, 2010Date of Patent: December 11, 2012Assignee: Casio Computer Co., Ltd.Inventors: Takashi Itoh, Hiroyuki Nakata, Motoyuki Kashiwagi

Patent number: 8169512Abstract: A digital still camera includes an amplification circuit, a timing generator, sample hold circuits, a differential amplifier, an analog/digital conversion circuit and a control unit. The generator generates a first-pulse signal and a second-pulse signal at different timings. The circuits sample analog video signals outputted from the amplification circuit at timings when the first-pulse signal and second-pulse signal, respectively, are provided and hold levels of the analog video signals. The amplifier acquires a difference between the levels of the analog video signals. The circuit obtains a digital video signal corresponding to the analog video signal on the basis of the difference. The unit changes the timings to provide the first- and second-pulse signals to the first- and second-sample hold circuits, respectively, and a bias current depending on the driving period.Type: GrantFiled: June 16, 2010Date of Patent: May 1, 2012Assignee: Casio Computer Co., Ltd.Inventors: Hiroyuki Nakata, Takashi Itoh, Motoyuki Kashiwagi

Publication number: 20100321516Abstract: In a digital camera apparatus, drive mode of CCD is set to AF mode in AF controlling operation (at step S4), and is set to a capture mode in a shooting operation (at step S12). AFE for processing an image signal output from CCD is held in a halt state during a rapid sweeping period, in which unnecessary charge that is not used as pixel information is discharged (at steps S5, S9, S13, S17), whereby power consumed by AFE in a shooting mode is reduced.Type: ApplicationFiled: June 7, 2010Publication date: December 23, 2010Applicant: Casio Computer Co., Ltd.Inventors: Motoyuki Kashiwagi, Hiroyuki Nakata, Takashi Itoh
