The invention is directed to a method and apparatus for storing image data received in a block-interleaved format using an MCU buffer A first minimum coded unit of the image data is stored in a first memory The image data in the first minimum coded unit is grouped into pixels The grouped image data is stored in a second memory as a second minimum coded unit of the image data Preferably, the image data is converted from a first color format to a second color format Further, the image is preferably dimensionally transformed

Method and apparatus for storing image data using an MCU buffer

The invention is directed to a method and apparatus for transforming the dimensions of an image represented by block-interleaved data. The method comprises: (a) storing a first minimum coded unit of the image data in a first memory; (b) dimensionally transforming the first minimum coded unit; and (c) storing a second minimum coded unit of the image data in the first memory. Steps (b) and (c) are performed after step (a). In addition, step (b) is performed before: starting to store any third minimum coded unit in the memory after step (c). The apparatus comprises a first memory, a storing circuit, a dimensional transforming circuit, and a timing control circuit. Preferably, the first memory is sized for storing no more than two minimum coded units.

Method and apparatus for transforming the dimensions of an image

The invention is directed to a method and apparatus for reducing the bandwidth required to transmit image data to a display device. It is contemplated that the image data represents a plurality of pixels defining an image for display on the display device, and that the image data is transmitted in a data stream with the data being in a predetermined order of pixel components. The method comprises the steps of receiving the image data from the data stream, and transforming the image data as it is received by selectively storing some of the image data in a memory for access by the display device and discarding other of the image data.

Method and apparatus for reducing the bandwidth required to transmit image data

PROBLEM TO BE SOLVED: To shorten processing time from the retrieval of binary type data stored in a database up to the output of a file converted into character strings. SOLUTION: As to binary type digital data of field configuration collected in a fixed section, the number of data, the number of delimiter bytes and data required for processing are stored (S11, S12) and the binary type data of each field are stored as they are in a memory as array data (S13). The position of data to be extracted is specified from the number of delimiter bytes of each field to be output to a file, the data are processed (numerically converted) by the size of the number of delimiter bytes (S14, S15), and the processed data are converted into a character string and written in a file as file output data (S16).

Data processing method

PROBLEM TO BE SOLVED: To provide an image converter and method, and a recording medium for decoding compressed data subjected to reduction processing without the need for a frame memory having a capacity of one screen image. SOLUTION: The image converter applies reduction processing to each unit block and provides an output of a result so as to avoid the size of a work memory required for the reduction processing from being increased even when the size of an input image increases. Further, the image converter decodes and reduces compressed data by each minimum unit at the same time so as to store only a reduced and decoded image. Thus, the downsized converter, reduced cost, and saved power consumption are attained. COPYRIGHT: (C)2004,JPO
