Patent number: 8363146Abstract: An image-taking apparatus generates an output image from a photographed image obtained by photographing and displays this output image on a display screen of a display section. The image-taking apparatus includes a recognition processing section for recognizing a specific subject (facial region of a person, or a facial component such as eyes) included in the photographed image. Referring to results of this recognition, the image-taking apparatus evaluates the dimension of the specific subject in each photographed image. If the dimension evaluated is relatively large, a relatively small magnification ratio to be employed upon the generation of the output image from the photographed image is provided. If the dimension evaluated is relatively small, a relatively large magnification ratio to be employed upon the generation of the output image from the photographed image is provided. As a result, the dimension of the specific subject in the output image is kept substantially constant.Type: GrantFiled: July 31, 2007Date of Patent: January 29, 2013Inventors: Hiroaki Yoshida, Yukio Mori, Yasuhachi Hamamoto, Seiji Okada, Satoru Takeuchi, Masahiro Yokohata

Patent number: 8000558Abstract: Based on, for example, the image at the start of a movie, a thumbnail image is tentatively generated and is stored in a header file. If a predetermined triggering condition is fulfilled during movie shooting, a thumbnail image is generated from the frame image at the timing that the triggering condition is fulfilled, and the thumbnail image existing in the header file is replaced with the newly generated thumbnail image. The triggering condition is fulfilled, for example, if, after zooming-in, the angle of view has been kept fixed for a predetermined period or longer, or if the focus has been kept locked for a predetermined period.Type: GrantFiled: March 21, 2007Date of Patent: August 16, 2011Assignee: SANYO Electric Co., Ltd.Inventors: Yukio Mori, Yasuhachi Hamamoto, Seiji Okada, Hiroaki Yoshida, Satoru Takeuchi, Masahiro Yokohata

Publication number: 20080112644Abstract: N separately-exposed images are serially captured in an additive-type image stabilization processing that generates one synthetic image having reduced influence due to camera shake by positioning and additively synthesizing a plurality of separately-exposed images. For each non-reference image (In), the strength (the degree of similarity) of a correlation between a reference image (Io) and each of the non-reference images is evaluated. Each of the non-reference image is determined whether valid or not according to the strength of each correlation. By using the reference image and valid ones of the non-reference images, a synthetic image is generated by additive synthesis.Type: ApplicationFiled: November 7, 2007Publication date: May 15, 2008Applicant: SANYO ELECTRIC CO., LTD.Inventors: Masahiro YOKOHATA, Yasuhachi Hamamoto

Publication number: 20080095408Abstract: There is provided an imaging apparatus and an imaging method capable of matching coordinate positions of a plurality of images to be synthesized with each other when generating an image having a wide dynamic range by synthesizing the plurality of images each having a different exposure condition. When a luminance adjustment circuit adjusts a luminance value of each of reference image data and non-reference image data, a displacement detection circuit detects displacement between the reference image data and non-reference image data. After a displacement correction circuit corrects coordinate positions of the non-reference image data on the basis of the detected displacement, an image synthesizing circuit generates synthesized image data composed of reference image data and non-reference image data.Type: ApplicationFiled: October 22, 2007Publication date: April 24, 2008Applicant: SANYO ELECTRIC CO., LTD.Inventors: Masahiro Yokohata, Yasuhachi Hamamoto, Yukio Mori

Publication number: 20070077055Abstract: The exposure time calculator calculates exposure time of image sensor based on an aperture value corresponding to a diaphragm and brightness of an object. The predetermined time calculator calculates predetermined time based on a focal length of a lens and a predetermined coefficient. The shooting mode determining unit determines execution of multiple-exposure shooting to obtain a composite image of the object by obtaining multiple object images and then combining the multiple object images in a case where the exposure time is equal to or longer than the predetermined time.

Patent number: 6075556Abstract: A method is disclosed, for encoding a signal with a three dimensional image sequence using a series of left and right images. Each image in the left image series is a picture formed by non-interlaced or interlaced scanned left line images, and each image in the right image series is a picture formed by non-interlaced or interlaced scanned right line images. The left line images contained in the left picture are merged with the right line images contained in the right picture to produce an alternately arranged left and right line merged picture. The merged picture is encoded using an MPEG-2 compliant encoder.Type: GrantFiled: March 26, 1998Date of Patent: June 13, 2000Assignee: Sanyo Electric Co., Ltd.Inventors: Takashi Urano, Hideo Kodama, Yasuhachi Hamamoto, Etsuko Sugimoto, Satoko Kobayashi

Patent number: 6011598Abstract: A decoding start controller is capable of appropriately decoding pictures up to the final picture, even if the amount of the data stored in a bit-stream buffer is reduced, as a result of partial storage of the data in an internal local buffer. Further, the decoding start controller is capable of decoding extremely short bit-stream data. If completion information, which is sent from an input side of the bit-stream data and represents completion of input of the bit-stream data, is detected, a decoding start instruction signal is output to a variable-length decoder regardless of a value of VBV occupancy. In short, when the amount of the data stored in the bit-stream buffer connected to the decoder having the decoding start controller, is equal or greater than the value of VBV occupancy, the decoding start instruction signal will usually be sent to the variable-length decoder: namely, so-called decoding start control operation based on value of VBV occupancy.Type: GrantFiled: March 28, 1997Date of Patent: January 4, 2000Assignee: Sanyo Electric Co., Ltd.Inventors: Yasunori Tsuji, Takashi Urano, Koichi Tsuchikane, Yasuhachi Hamamoto
