摘要： According to an embodiment, an image decoding apparatus includes a memory, a decoder and a first filter. The memory stores reference pixels based on pixels included in a decoded pixel block. The decoder decodes encoded data in units of pixel blocks using the reference pixels to generate a first decoded pixel block, the first decoded pixel block being adjacent to the reference pixels. The first filter performs a first filtering on only the first decoded pixel block using the first decoded pixel block and part of the reference pixels perpendicularly adjacent to the first decoded pixel block in a scan direction of image decoding processing.

摘要： According to an embodiment, an encoding device includes a determination unit, a first palette generator, a first assignment unit, an encoder, and a first reference generator. The determination unit is configured to determine an additional palette that holds a color not included in a reference palette among colors included in a predetermined operation unit of an input image. The first palette generator is configured to generate a palette for encoding including a color included in the additional palette and a color included in the reference palette. The first assignment unit is configured to assign, to each pixel in the operation unit, an index indicating a color in the palette for encoding corresponding to a color of the pixel. The encoder is configured to encode the index and information on the additional palette. The first reference generator is configured to generate the reference palette from the palette for encoding.

摘要： An image compression device includes: a first encoder that encodes a target block included in a segment in a first encoding mode; a second encoder that encodes the target block in a second encoding mode using a fixed-length coding to obtain a second encoded data; a calculator that calculates an accumulated amount of the first encoded data of the blocks; a selector that selects an encoding mode to be used to encode the target block from among the first encoding mode and the second encoding mode; and a determiner that determines whether to encode encoding mode information according to a predetermined condition. The selector selects the second encoding mode if a sum of an accumulated amount and an amount of the second encoded data of all remaining blocks in a segment exceeds a target value.

摘要： According to one embodiment, an acquisition unit acquires a pixel block having a predetermined size from image data to be coded. A comparison unit calculates a distance between a color of a target pixel in the pixel block and each of a plurality of typical colors, and selects a typical color of which the distance is a minimum distance from the plurality of typical colors. A decision unit assigns a first index representing the selected typical color to the target pixel if the minimum distance is smaller than a first threshold, assigns a second index representing a new typical color to the target pixel if the minimum distance is larger than the first threshold, and adds the color of the target pixel as the new typical color when the second index is assigned. A coding unit codes the selected typical color, the new typical color, the first index and the second index.

摘要： According to one embodiment, a control method includes setting a transmission angle of an ultrasonic wave to a standard angle. The control method further includes transmitting an ultrasonic wave at the set transmission angle and detecting an intensity of a reflected wave from an object. The control method further includes calculating a tilt angle based on a gradient of the intensity. The tilt angle indicates a tilt of the object. The control method further includes resetting the transmission angle based on the tilt angle.
