Publication number: 20080037975Abstract: In an imaging device, a photographic scene is automatically determined with high accuracy. Distance information is acquired, through a TTL-AF, from an image signal produced by a CCD. Further, a face recognition circuit detects the face of a person in a subject. An AE-AF-AWB value computing section evaluates the reliability of the distance information acquired through the TTL-AF operation, on the basis of a focal length of a lens, an aperture, and a distance to the subject computed from a distance between eyes included in the detected face. A mode-recognition-and-determination-and mode-selection section automatically determines the photographic scene from the distance information acquired through the TTL-AF operation, the reliability of the distance, and an estimated white balance value.Type: ApplicationFiled: December 13, 2006Publication date: February 14, 2008Inventor: Kenichi Nakajima

Publication number: 20070183831Abstract: In a sticky note printer, a sticky note is peeled off and fed one by one from a bundle of notes set in position. In empty-feed motion, the sticky note is fed in a normal direction from a peel-off position through a sticky note ejecting slot to a pull-out position in which the sticky note protrudes outside the sticky note printer. In feed-back motion, the sticky note is fed in a reverse direction from the pull-out position to a retracted position in which printing can be performed. In feed-again motion, the sticky note is fed in the normal direction from the retracted position to the pull-out position. The empty-feed motion is made when the sticky note has been pulled away from the pull-out position. The feed-back motion or the feed-again motion is made, when an instruction for printing is given, in a manner synchronized with the printing operation.Type: ApplicationFiled: January 10, 2007Publication date: August 9, 2007Applicant: SEIKO EPSON CORPORATIONInventor: Kenichi Nakajima

Publication number: 20070025718Abstract: The present invention provides a digital camera that is capable of capturing a picture in which the brightness between a main subject and a nighttime background are well balanced. When an image capture instruction is received while a night scene portrait mode is set, in a pixel addition output mode, an image sensor 16 is set to a high sensitivity state by performing pixel addition, and outputs low resolution non-flash image data. Further, in an overall pixel output mode, the image sensor 16 outputs high resolution flash image data in a low sensitivity state without performing pixel addition. Next, a resolution conversion circuit 40 converts a resolution of non-flash image data to be equivalent to a resolution of flash image data. Then, an image combining circuit 60 adds respective pixel values of corresponding pixels in the non-flash image data and the flash image data having the same resolution and combines both sets of image data to generate image data for recording.Type: ApplicationFiled: December 21, 2005Publication date: February 1, 2007Inventors: Keiichi Mori, Sumito Yoshikawa, Kenichi Nakajima

Patent number: 7008040Abstract: There are provided an ink jet printer capable of printing efficiently by reducing the useless operation dependent on the width of a print image to thereby increase the printing speed and an image printing system incorporating the ink jet printer, as well as printing methods therefor. In one aspect, a print head capable of simultaneously printing M dots at a predetermined nozzle pitch in an X-axis direction is scanned in the X-axis and a Y-axis direction, to print an image on a medium. The print image width in the Y-axis direction is detected. Depending on the width, a head moving pitch in the X-axis direction relative scan is determined. The scanning of the head in the X-axis direction relative to the print medium prints maximum M dot lines along the X-axis juxtaposed in the Y-axis direction. The scanning of the head in the Y-axis direction is effected by moving the head relative to the medium at the head moving pitch, after printing by the scanning of the head in the X-axis direction.Type: GrantFiled: January 17, 2002Date of Patent: March 7, 2006Assignee: Seiko Epson CorporationInventor: Kenichi Nakajima
