An image processing apparatus and an image processing method are provided. The image processing apparatus includes: a division control unit that, on the basis of a first boundary dividing an image into a plurality of partial areas, further sets a second boundary and divides each of the partial areas into a plurality of slices; and an encoding unit that encodes the image on the basis of the first boundary and the second boundary, in which the division control unit sets the second boundary such that the plurality of slices included in the partial area has unequal numbers of lines, and the slice situated at the bottom among the plurality of slices included in the partial area is not a slice having the most lines in the partial area.

Image processing apparatus and image processing method

An encoder for encoding an image signal, the encoder including processing circuitry that sets, as a block setting process and in case that a condition that an operating mode requires resource efficiency higher than that of a normal mode, a depth of block division with more limited variety of pixel sizes of coding units than that of the normal mode; performs cost calculation and divisional determination only with respect to coding units within the set depth; and skips cost calculation and divisional determination with respect to coding units outside the set first depth.

Image processing device, image processing method, and program

An image processing system, method and device for processing an image signal. The image processing system, method and device receive an operating mode signal indicative of a determined operating mode associated with resource efficiency, and control a depth of block division for a block setting process based on the determined operating mode indicated by the operating mode signal.

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.

Image processing method and image information coding apparatus using the same

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.

Motion prediction compensating device and its method

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. The present invention may be applied to an IC card for receiving/transmitting data under non-contact state.
