Patent number: 7379090Abstract: An image capture apparatus includes an image capture unit, an internal memory, a digital communication unit, a display unit and a control unit. The image capture unit captures an image. The internal memory stores the captured image. The digital communication unit sends the captured image stored in the internal memory to an external device. The control unit (i) selects a low-speed transfer mode if the display unit displays an image, and (ii) selects a high-speed transfer mode if the display unit does not display an image. Both the low-speed transfer mode and the high-speed transfer mode are used for transfer of data between the internal memory and the digital communication unit for transfer of the captured image to the external device.Type: GrantFiled: June 10, 2003Date of Patent: May 27, 2008Assignee: Canon Kabushiki KaishaInventor: Atsushi Katayama

Patent number: 6278755Abstract: A bit synchronization circuit extracts the central phase of an eye opening irrespective of a jitter distribution of input data to maintain an optimum timing adjustment margin. The bit synchronization circuit has a data edge detector for comparing the phases of an edge of the input data and m-phase clock signals divided from a reference clock. Data edge phase information from the data edge detector is accumulated by a phase accumulation register, which stores the jitter distribution of the input data as accumulated phase information. Based on the accumulated phase information, an eye center phase calculator decodes the negative and positive ends of a jitter range as negative jitter range information and positive jitter range information, and calculates a phase control direction in relation to an extracted phase value which represents a presently selected clock phase.Type: GrantFiled: May 8, 2000Date of Patent: August 21, 2001Assignee: NEC CorporationInventors: Mitsuo Baba, Yasushi Aoki, Minoru Kayano, Yuuji Takahashi, Atsushi Katayama

Patent number: 6166810Abstract: A method and apparatus for precision distance measurement are provided to perform accurate measurement of distance to an object according to light spots formed on the light receiving surface of a detector even when multiple reflections are involved. A beam of light emitted from a light source and reflected from the object is focused on the viewing surface as light spots through an optical member. The focal position of a reflected beam of light is determined according to a focal position detection process. When there are peaks in a luminosity curve generated on the detector, prior to performing the focal position detection process, the peaks are separated into individual light spots and a correct light spot for deriving the precise distance is selected by a selection process.Type: GrantFiled: December 3, 1998Date of Patent: December 26, 2000Assignee: Nippon Telegraph and Telephone CorporationInventors: Joji Nakayama, Atsushi Katayama
