  • Patent number: 11568516
    Abstract: A solution to the problem of image and video stitching is disclosed that compensates for the effects of lens distortion, camera misalignment, and parallax in combining multiple images. The disclosed image stitching technique includes depth or disparity estimation, alignment, and blending processes configured to be computationally efficient and produce quality results by limiting the presence of noticeable seams and artifacts in the final stitched image. An inter-frame approach applies image stitching to video frames to maintain temporal continuity between successive frames across a stitched video output having a 360-degree viewing perspective. A temporal adjustment is configured to improve temporal continuity between a subsequent frame and a previous frame in a sequence of video frames.

  • Patent number: 9596407
    Abstract: An imaging device includes an imaging section, an image segmenting section, and a blur enhancement section. The imaging section images a field to generate photographic image data. The image segmenting section partitions an image of the photographic image data into a first region that is a main subject region and a second region where the main subject is not included. The blur detecting section detects degree of blur of an image of the second region of the image of the photographic image data. The blur enhancement section performs blur enhancement processing on the image of the second region to enlarge the degree of blur of the image after image processing in proportion to the magnitude of the detected degree of blur of the image.

  • Patent number: 8792716
    Abstract: An image processing apparatus for region segmentation of an obtained image is provided. The image processing apparatus may include a detecting unit detecting, among plural fundamental regions set to an image, a fundamental region satisfying a predetermined condition as an appropriate region. The image processing apparatus may further include a specifying unit specifying adjacent states of fundamental regions excluding the appropriate region among the plural fundamental regions. The image processing apparatus may also include a region segmentation unit performing region segmentation on each component included in the image based on the adjacent states of the fundamental regions excluding the appropriate region specified by the specifying unit.

  • Patent number: 7703602
    Abstract: An easy-open encasement formed of a soft encasement member in the form of a film. An opening or an openable portion is formed in the soft encasement member, which allows a user to extract contents from the encasement. Furthermore, a lid member, which can be peelably adhered to the soft encasement member, is adhered to the surface of the soft encasement member such that it covers the opening or openable portion. With such a structure, a tab is provided at a part of the perimeter of the lid member, which serves as a starting point that allows the user to peel off the lid member. Furthermore, the tab includes a hinge portion, which allows the user to raise the tab, or a flap elevated from the surface of the encasement.

  • Patent number: 7475781
    Abstract: A package is presented from which contents can be easily taken out. This package includes a film with a soft packaging material. On the surface of the soft packaging material is a cut line, such that, inside the cut line, an openable region is formed for taking contents out from the package. Further, inside the openable region, dashed lines are provided. When a lid member adhering to cover the openable region is peeled, the openable region easily adheres to the lid member side owing to the dashed lines to reliably form the opened portion.

  • Publication number: 20040206651
    Abstract: Disclosed is a wet sheet container for housing a sheet roll that is a wet sheet wound in the form of a roll. A container body is formed with a storage space into which the sheet roll is to be inserted. The container body is separable into two or more parts so that separation of the container body allows insertion of the sheet roll into the storage space. A shaft is located inside the container body so as to be inserted into a center hole of the sheet roll. The shaft defines a support space which extends along an axial direction thereof and communicates with the outside of the container body.
