A display control apparatus according to an embodiment of the present invention includes: a grayscale converting circuit for converting input image data to output image data using a look-up table showing a correspondence between input image data of i bits and output image data of k bits larger than the i bits; and an LUT creating circuit for creating the look-up table based on γ data of 2k bits. The apparatus further includes a γ data storage circuit capable of storing the plural γ data in the LUT creating circuit.

A device for sequentially storing input bit symbols of a given interleaver size N in a memory at an address from 0 to N−1 and reading the stored bit symbols from the memory. The device comprises a look-up table for providing a first variable m and a second variable J satisfying the equation N=2m×J; and an address generator for generating a read address depending on the first and second variables m and J provided from the look-up table. The read address is determined by 2m(K mod J)+BROm(K / J), where K (0≦K≦(N−1)) denotes a reading sequence, BROm(y) is the bit-reversed m-bit value of y and / is a function in which a quotient of K divided by d is obtained, the quotient being an integer.

The invention discloses a DTMB symbol de-interleaving method. The method comprises the following step: a de-interleaving memory is logically divided into 52 rows such as from row 0 to row 51; each row respectively writes 72 symbols in a same interleaved frame; row 0 writes the symbols such as 0, 52, 104, ..., 3692 of an interleaved frame; row 1 writes 72 symbols such as 1, 53, 105, ..., 3693; row 51 writes the symbols such as 51, 103, 155, ..., 3743; row N contains (52-N+R) blocks, R is 0 or a positive integer, and the size of each block is M symbols; after data of the interleaved frame fully writes the last block in a row of the de-interleaving memory, subsequent data memorized in the row is covered in the block written with invalid data of the row; 51 X 52 symbols are fully prewritten when initialization; and then a frame of de-interleaving common signal data is read out every frame symbol is written. The application of the method can reduce the consumption of time domain symbol de-interleaving memory space.

A printing device enables a laid-out and drawn image to be printed without any subsequent rotation. In the presence of an orientation change command, the printing device receives a layout command and determines a layout of each object in each page on the medium with conversion of coordinates at a preset position of the object. In the presence of the orientation change command, the printing device receives a print command, fetches an object according to the stored layout in each page, and draws and prints the fetched object in response to the orientation change command. No subsequent orientation change of drawing data, which has been laid out and drawn in the specified page orientation, is required to generate converted drawing data corresponding to the specified medium orientation.

An image processing apparatus for compositing multiple component images into a composite image is proposed. The image processing apparatus includes: a separating unit that separates a codestream corresponding to each one of the component images into a header portion and a data portion; a header processing unit that edits the separated header portion; and a codestream generation unit that generates a codestream corresponding to the composite image by combining the edited headers and the separated data portions. Each component codestream is generated by dividing the corresponding one of the component images into one or more rectangular regions, transforming pixel values of the divided one or more rectangular regions with discrete wavelet transform into transform coefficients, and compressing the transform coefficients.

The invention relates to a storage system with flash memories, which mainly comprises a microcontroller, at least a flash memory connected with the microcontroller, and a scratch pad storage. A plurality of entity storage area blocks are included in each flash memory; an entity address and a plurality of entity sectors are included in each entity storage area block; each entity sector at least comprises a user data field and a logical address pointing column, wherein logical address pointing data can be written into each logical address pointing column when entity data is stored in the user data field; a logical address of a logical storage area block corresponding to each entity storage area block can be recorded in the logical address pointing data; the scratch pad storage is connected with the microcontroller, and can be used for storing a connection comparison table; and the entity address of each entity storage area block and the logical address of one of the logical storage area blocks corresponding to the entity storage area blocks can be recorded in the connection comparison table. The storage system with the flash memories can not only ensure secure data access, but also save the internal storage capacity and the electric energy loss of the scratch pad storage.

The invention relates to a method, device arrangement and a terminal for transferring a message received in a first terminal in a controlled manner from said first terminal to a second terminal. In the method, the messages are searched for possible references to resources outside the message, and information is downloaded from these resources for later examination.

An image processing apparatus for processing an image, includes a face detector for detecting an image of a face of a subject contained in a captured image, based on image information of the captured image supplied from an imaging unit, a face feature detector for detecting a face feature contained in the face image, based on image information of the face image detected by the face detector, a normalizer for normalizing the face image detected by the face detector, based on a detected position of the face feature detected by the face feature detector and generating a normalized face image, and a face expression detector for detecting a face expression contained in the face image, based on image information of the normalized face image generated by the normalized.

A file system includes a processing device that processes first data with at least one of a copying function to read image data of an original document and record the read image data on a sheet, a transmitting function to send and receive image data and / or character data via a communication line, and a recording function to record received image data and / or character data on a sheet. The file system also includes a memory device to store the first data processed by the processing device, an identity determination device to determine an identity (i.e., similarity or relation) between the processing data and second data stored in the memory device, and a storage management device stores the first data into the memory device on the basis of a result of a determination made by the identity determination device. The storage management device cancels the storage of the first data into the memory device when the identity determination device determines that the first data is identical to second data stored in the memory device. The identity determination device determines the identity between the first data and the second data stored in the memory device based upon information of processes with which the first data has been processed with the processing device. The information of processes includes information of an original document associated with the first data.
