    摘要: A picture processing apparatus includes a decoder configured to decode encoded data to generate a decoded picture. A picture memory has a plurality of banks each containing a plurality of pages to which row addresses are assigned, and is configured to store the decoded picture. A bank selector is configured to divide the decoded picture into a plurality of blocks, and to select a page of a different bank as a write location for a block adjacent in at least one of either a horizontal direction or a vertical direction. A write controller is configured to write pixel data of pixels occupying even lines of each of the blocks, and pixel data of pixels occupying odd lines of each of the blocks in a column address direction of each of the page in an alternating manner.

    摘要: According to one embodiment, an image processing device includes a plurality of parallax image generators. Each of the parallax image generators is configured to generate a first image and a second image based on an input image and a parameter for setting a distance between viewpoints. There is a first parallax between the first image and the second image. The first parallax depends on the parameter for setting the distance between viewpoints. The input image is inputted to the parallax image generators in common. A plurality of parameters for setting the distance between viewpoints different from each other are inputted to the parallax image generators, respectively.

    摘要: A decoding apparatus using tables T1, T2, and T4 has a buffer memory (1), a code word separation circuit (2), a comparator (31), and an addition circuit (4). In the table T1, decoded data items corresponding to each code word are stored based on each code length as index. In the table T2, addresses in the table T1 corresponding to the minimum value in code words having each code length is stored based on the code length as index. In the table T4, the number of code words having each code length is stored based on the code length as index. The buffer memory (1) stores the real data part in a bit stream transferred from outside. The code word separation circuit (31) separates each bit data item from the buffer memory (1). The comparator (31) analyses the content of the data item transferred from the code word separation circuit (2). The addition circuit (4) adds the output from the comparator (31) to the output from the table T2.
