  • Patent number: 8565312
    Abstract: An image information coding method for performing a motion vector search based on hierarchical search in an image compression information device adapted to output image compression information. The image information coding method includes the steps of, compressing a plurality of frame images at a predetermined compression ratio to generate a plurality of reduced screens of lower hierarchical levels, searching for a first motion vector using the plurality of reduced screens, switching between search areas in a memory in which the frame images are stored, and searching for a second motion vector using the first motion vector in the switched search area.

  • Publication number: 20130058416
    Abstract: An image processing apparatus and an image processing method capable of further improving coding efficiency while suppressing an increase in a load. For example, in a case a macro block with a size of 16×16 pixels or less used in AVC is a coding process target, a motion search and compensation unit performs a motion search using an image with the original size which is not reduced. In addition, for example, in a case where an extended macro block with a size larger than 16×16 pixels is a coding process target, the motion search and compensation unit performs a motion search using a reduced image.

  • Patent number: 7746930
    Abstract: An object of the invention is to provide a prediction compensation device and its method in which the processing efficiency of the overall coding process is enhanced. The address of an object pixel block serving as a pixel block of prediction object among a plurality of pixel blocks is detected, a first search range or a second search range narrower than the first search range is decided as the search range of a motion vector for the object pixel block on the reference frame according to the detected address, and the motion vector is searched for from the decided search range around the predictor of the motion vector based on the surrounding pixel blocks adjacent to the object pixel block.

  • Publication number: 20090092189
    Abstract: Disclosed herein is a movement-prediction/compensation method for carrying out processing based on search layers to search for a movement vector by selecting one or more reference frame images for each of movement-compensated blocks obtained as a result of dividing a processed frame image existing among successive frame images. The method includes: a layer creation step; a first movement-prediction/compensation step; a reference frame image determination step; and a second movement-prediction/compensation step.

  • Publication number: 20080037642
    Abstract: When motion vector is searched based on hierarchical search by designating any one of reference images of plural frames used every respective motion blocks, which have reference images of plural frames and are obtained by dividing an object frame image to be processed among successive frame images, a thinning unit (12) is operative to thin pixels of the motion compensation block having the largest pixel size caused to be uppermost layer among pixel sizes of the motion compensation block to thereby generate a contracted image of lower layer having a predetermined contraction factor; a reference frame determination unit (15) is operative to determine a contracted reference image on the contracted image; a motion compensation prediction unit (1/N2 resolution) (15) is operative to search motion vector by using the contracted image thus generated to search; with respect to an image before contraction, motion compensation prediction unit (full resolution) (17) is operative to search motion vector and perform motion

  • Publication number: 20070286281
    Abstract: In a picture information encoding apparatus that outputs picture compression information according to a picture encoding system such as MPEG4/AVC, when it is determined whether the mode of a predetermined block is a skip mode or a spatial direct mode, moving vector information and so forth for all of predetermined adjacent blocks needs to have been computed. However, when each block is processed in parallel to speed up the entire processes, moving vector information and so forth of the predetermined adjacent blocks may not be always obtained. In this case, moving vector information and so forth of neighbor blocks instead of adjacent blocks are pseudo-used to determine the mode of the block without need to wait until moving vector information and so forth of adjacent blocks have been computed.

  • Patent number: 6950074
    Abstract: The present invention relates to an electronic device that suppresses reduction in reception sensitivity and occurrence of distortion when IC cards are used while stacked. A loop antenna equipped on the IC card has up to four turns, and is designed so that one turn, for example, has a first linear portion, a first curved line portion, a second linear portion, and a second curved line portion. When two electronic devices having a first loop antenna and a second loop antenna, respectively, are stacked onto one another, the corners of the loop antennas do not overlap. For example, the corner formed by first curved line portion and the second linear portion of the first loop antenna is overlapped with the first curved line portion of the second loop antenna. The first and second loop antennas are shaped such that when two electronic devices are stacked, their respective loop antennas are superimposed in the opposite direction so that the corners are not overlapped and the amount of overlap as a whole is reduced.

  • Publication number: 20050111551
    Abstract: A data processing apparatus, a method of data processing and an encoding device are provided. The data processing apparatus is capable of encoding all motion compensation block data, wherein, when generating for example a motion vector MV of a motion compensation block data A in macro block data MB_X, when the motion vectors MV of the motion compensation block data B1, B2, and B3 at the periphery of that are not generated, a predictive vector generation unit of a motion prediction and compensation circuit generates a predictive motion vector PMV of the motion compensation block data A by using already generated motion vectors MV of motion compensation block data C1, C2, and C3 in the adjacent macro block data MB_Y in place of them.

  • Publication number: 20030151561
    Abstract: The present invention relates to an electronic device that suppresses reduction in reception sensitivity and occurrence of distortion when IC cards are used while stacked. A loop antenna 1 equipped to the IC card has four turns, and it is designed so that one turn comprises a linear portion L2, a curved line portion L3, a linear portion L4 and a curved line portion L5, for example. When two loop antennas 1 having such a shape is stacked with being faced in the opposite directions, the corners thereof are not overlapped. For example, the corner formed of the curved line portion L3 and the linear portion L4 of the loop antenna 1 is overlapped with the curved line portion L3 of the loop antenna 1 superimposed with being faced in the opposite direction, so that the corners are not overlapped and the overlap portion is reduced as a whole. The present invention may be applied to an IC card for receiving/transmitting data under non-contact state.

  • Patent number: 4498415
    Abstract: Can end disks have annular, curled rims on which a sealing composition is applied as a coat to form airtight seals when the end disks are subsequently attached to can bodies. The sealing composition is sprayed onto the curled rim of each can end disk by an overlying spray nozzle while the disk is being rotated on a rotary rest in a coating machine. For detecting uncoated regions on the curled rim of the can end disk, a photodetector is positioned over the rim of the disk on the rotary rest, with a preassigned angular spacing between the photodetector and the spray nozzle. The detection of uncoated regions is essentially concurrent with the application of the sealing composition. Since the output from the photodetector represents a nonfaulty uncoated region (i.e. a region not yet coated), in addition to a possible faulty uncoated region (i.e.
