摘要： A decoding device decodes coded image data having a plurality of color components and includes a variable length decoding unit that performs variable length decoding on the coded image data to generate variable length decoded data. A separation unit separates the plurality of color components to a predetermined number of color components, and obtains, from the variable length decoded data generated by the variable length decoding unit, each of pieces of data to be decoded in decoding processes, as necessary data required in at least one of decoding processes, and the decoding processes each corresponding to a corresponding component of the predetermined number of color components. Each of the image reconstruction units corresponds to a corresponding component of the predetermined number of color components, and generates, in parallel, decoded images regarding the respective components using the necessary data obtained by the separation unit.

摘要： PURPOSE: An apparatus and a method for coding an image are provided to improve the processing speed substantially when coding a variable length of an image. CONSTITUTION: A 2D DCT(Discrete Cosine Transform) unit(101) performs a DCT operation for inputted image data, and a zigzag scan unit(103) performs a zigzag scanning operation for every DCT coefficient block. A quantization unit(104) quantizes read DCT coefficient based on a preset quantization value, and an intermediate code generator(105) creates an intermediate code on the basis of the quantized DCT coefficient. Based on a non-zero coefficient and a zero run length, a variable-length coding unit(107) generates a Haffman code.

摘要： The present invention relates to an encoding device and a method, a decoding device and a method, an editing device and a method, a storage medium, and a program which can perform encoding and decoding so that buffer failure does not occur. Information, such as a minimum bit rate, a minimum buffer size, and a minimum initial delay time, is contained in a random access point header contained in an accessible point in a bitstream. A bitstream analyzing unit 72 analyzes an input bitstream, sets the above-mentioned information, and outputs the resulting information to a buffer-information adding unit 73. The buffer-information adding unit 73 adds the input information to the input bitstream and outputs the resulting bitstream. The present invention is applicable to an encoding device and a decoding device which process bitstreams.

摘要： PROBLEM TO BE SOLVED: To prevent growth of a required buffer memory by maintaining the number of pixels configuring a template shape even if the pixels configuring the template of an NLM filter exceeds a specified boundary.SOLUTION: When the pixels configuring a template shape exceeds the border line of a specified image to be processed for a predetermined template shape, a template shape setting unit 203 sets a template shape rearranged so that the number of pixel exceeded the border line fall within the border line. An NLM filter execution unit 204 removes noise of pixels to be de-noised in a processed image by using a template of a template shape set by the template shape setting unit 203.
