According to an embodiment, a storage controller comprises a circuitry configured to implement an address generator, a reader, and a duplication detector. The address generator is configured to generate a scan address indicating each storage area of a storage that stores therein externally written data, according to a particular scan pattern for defining an order of an address of data to be read. The reader is configured to read data from the storage area of the storage indicated by the scan address. The duplication detector is configured to detect whether the data read by the reader is a duplicate of any one of a past predetermined number of pieces of data.

First coded data are generated from a target block by a first coding mode. Second coded data having predetermined amount are generated from the target block by a second coding mode. Whether to encode by the first coding mode or the second coding mode is decided. Based on the decision result, any of the first coded data and the second coded data is selected. If a total amount of coded data of a segment is over a target amount, encoding by the second coding mode is decided. The segment comprises blocks including the target block. The total amount is sum of an amount of coded data generated from blocks prior to the target block in the segment, an amount of the first coded data, an amount of coded data to be generated from remained blocks in the segment by the second coding mode.

According to an embodiment, a data storage system includes a host computer performing input and output of data, and a data storage device connected to the host computer. The data storage device includes a compressor to compress data input from the host computer; a memory to store compressed data compressed by the compressor; and a first interface. When first writing data a input from the host computer, the first interface sends second writing data obtained by compressing the first writing data to the host computer. When address information corresponding to the first writing data is input from the host computer, the first interface sends read-compressed data representing the compressed data read from the memory based on the address information, to the host computer. The host computer includes a determiner to determine that the first writing data is already stored when the second writing data is identical to the read-compressed data.

According to an embodiment, a reproduction device includes an acquirer, a decoder, and a synthesizer. The acquirer is configured to acquire transmission information including first and second coded data. The first and second coded data are generated by encoding first and second image data, respectively. At least one of the first and the second image data is lossy encoded. The first and second image data being generated by performing conversion processes different from each other on original image data. The decoder is configured to decode the first and second coded data to generate first and second decoded data. The synthesizer is configured to synthesize the first and the second decoded data with adjusting pixel positions of the first and the second decoded data so that the pixel positions of the first and the second decoded data are identical to each other to generate reproduction image data.

According to an embodiment, a stereoscopic image encode device encodes a stereoscopic image displayed on a display device including a light control unit capable of controlling directions of light beams and including a display for emitting light beams from sub-pixels through the light control unit. The stereoscopic image encode device includes a determining unit, a generating unit, and an encoding unit. The determining unit configured to determine a method of dividing the stereoscopic image for each color component based on mapping information indicating the direction of emitted light beam from each sub-pixel, when the number of sub-pixels corresponding to a single cycle of the light control unit is not an integral multiple of the number of parallaxes in the stereoscopic image. The generating unit configure to generate a plurality of divided image. The encoding unit configured to encode each divided image.

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.
